Hyperthyroidism in cats | Author : G. Ajitkumar and R. Praseeda | Abstract | Full Text | Abstract :Hyperthyroidism, primarily due to functional thyroid adenoma, is the most common endocrinopathy of older cats worldwide. Even though the etiopathogenesis of feline hyperthyroidism
is not yet fully understood, the four common therapeutic modalities that can be implemented individually or in combination for management are surgical thyroidectomy, radioactive iodine, pharmaceutical therapy and dietary therapy using a limited-iodine diet. Regular monitoring of a hyperthyroid cat is important to assess therapeutic efficacy, to detect iatrogenic hypothyroidism and to confirm comorbidities that become evident with resolution of the hyperthyroidism.
Thyroid gland is an endocrine gland located at the neck area. In cats, this gland has two
lobes connected by an indistinct isthmus. The functional unit of the gland is the thyroid follicle and the
three hormones produced are triiodothyronine (T3), thyroxine (T4) and calcitonin. Secretion of T3
and T4 are regulated by the thyroid-stimulating hormone (TSH) and thyrotropin-releasing hormone
(TRH) produced by the pituitary gland and hypothalamus, respectively. Ectopic or accessory
thyroid tissue is relatively common in many species including cats and may be located anywhere
from the larynx to the diaphragm. Hyperthyroidism is characterized by the overproduction of
thyroid hormone and a subsequent increase in metabolic rate |
| Seroprevalence of leptospirosis in cattle in Mannancherry panchayat of Alappuzha district | Author : S. S. Sreekutty, K. Vrinda Menon, C.Latha, B. Sunil, R. Ambily | Abstract | Full Text | Abstract :Cattle can act as asymptomatic carrier in leptospirosis and can transmit the infection to
other animals and humans either by direct contact or indirectly by contaminating the environment
with infected urine. Thus, the role of apparently healthy cattle in the maintenance and transmission
of the organism needs to be studied. The present study was conducted in 90 apparently healthy
cattle in Mannancherry panchayat of Alappuzha district. Serum samples were collected from cattle
and subjected to Microscopic Agglutination Test (MAT) using a battery of serovars. A serum dilution
of 1:50 and above was taken as positive. Out of the 90 samples analysed, 47 (52.2 per cent) were
found positive. The predominant serovars observed in the study were Grippotyphosa (34.04 per
cent), Sejroe (25.53 per cent) and Autumnalis (21.3 per cent). The study revealed the importance
of asymptomatic cattle in the maintenance and transmission of the disease. |
| Occurrence of vaginal hyperplasia among intact dogs | Author : Anila Babu, B. Bibin Becha, C. Jayakumar, Shibu Simon, Indu V. Raj and M.O. Kurien | Abstract | Full Text | Abstract :Hyperplasia of vaginal mucous membrane is an unusual reproductive disorder observed
in canines. It is the protrusion of oedematous vaginal tissue into and through the opening of the
vulva occurring during proestrus and oestrus stages of the sexual cycle. This study was aimed to
find out the overall occurrence of canine vaginal hyperplasia and its occurrence based on breeds,
age, parity and stage of oestrous cycle. The occurrence of canine vaginal hyperplasia was 1.02
per cent. The highest occurrence of vaginal hyperplasia within a breed was observed in Labrador
retrievers (48.94%), while the lowest occurrence was in German shepherd, Spitz, and Dachshund
breeds (2.13%). The highest occurrence was recorded in dogs of one to two years old (43.62%)
and the lowest occurrence in dogs of above 4 years of age (13.83%). Highest occurrence of vaginal
hyperplasia was found in nulliparous (60.71%) and in intact dogs (100%). |
| Effect of jackfruit powder on the physicochemical and sensory attributes of poultry meat cocktail nuggets | Author : Silpa Sasi, T. Sathu, C. Sunanda, M. Pavan,V.N. Vasudevan, A. Irshad, and S. Kiran Kumar | Abstract | Full Text | Abstract :The present study was designed to investigate the effect of jackfruit powder on the
physicochemical characteristics, proximate composition and sensory attributes of cocktail nuggets
containing 75 per cent chicken and 25 per cent duck meat. Jackfruit powder was added in cocktail
nuggets at three different levels i.e., one, two and three per cent over and above the cocktail
nuggets formulation and its effect was evaluated against control cocktail nuggets. There was no
significant difference in emulsion pH values of control and jackfruit powder incorporated treatment
samples. When compared to control nuggets, significant increase was noticed in the product pH
of all the three treatment nuggets incorporated with jackfruit powder. No significant difference was
observed in the water activity and cooking yield of treatment and control nuggets samples. No
significant difference was observed in the moisture, fat, carbohydrate and calorie content of the
jackfruit powder added treatments and control nuggets. Protein percentage of treatment samples
were significantly lower than the control nuggets. Significantly higher ash content was observed for
jackfruit powder incorporated treatment samples when compared to control samples. On sensory
evaluation, no significant difference was observed for the appearance and flavour between
control and the treatment samples. Functional cocktail nuggets containing three per cent jackfruit
powder had significantly lower values for juiciness, texture, saltiness, mouth coating and overall
acceptability when compared to other treatment and control samples. The addition of jackfruit
powder in the nugget formulations was effective in sustaining the desired sensory attributes
besides the nutritional benefits. Hence, acceptable functional cocktail nuggets can be made with
the addition of jackfruit powder up to two per cent over and above the cocktail nuggets formulation
without affecting the sensory attributes. |
| Antibiogram of Escherichia coli isolates from faecal samples of neonatal calf diarrhoea in Wayanad distr | Author : M. Xavier, A. Janus, P. M. Deepa , K. C. Bipin, B. P. Habeeb, K. Vijayakumar | Abstract | Full Text | Abstract :Thirty faecal samples were collected from diarrhoeic neonatal calves reared in organized
farms and households of Wayanad district. The collected rectal swabs were subjected to bacterial
isolation and biochemical tests. Based on their cultural and biochemical characteristics isolates
were confirmed as Escherichia coli. Based on clinical signs and bacterial isolation calves were
diagnosed as affected with colibacillosis. Antibiotic sensitivity patterns of the isolates were evaluated
using standard disc diffusion method in Muller Hinton Agar. Antibiogram revealed susceptibility to
Chloramphenicol (70.0 per cent), Trimethoprim/Sulphamethoxazole (60.0 per cent), Ceftriaxone
(33.3 per cent), Ampicillin (33.3 per cent) and Tetracycline (3.3 per cent). The sensitivity patterns
of the isolates to the three antibiotics viz. Trimethoprim/Sulphamethoxazole, Ceftriaxone and
Ampicillin correlated well with clinical response. |
| Occurrence of repeat breeding and prolonged oestrus in crossbred cattle | Author : H.D. Arun, B. Bibin Becha, C. Jayakumar, M.P. Unnikrishnan, K.S. Ajith and M.O. Kurien | Abstract | Full Text | Abstract :Study was conducted to determine the occurrence of repeat breeding and prolonged
oestrus among crossbred cattle in organized farms. Data were collected from breeding registers
maintained on farms over a period of four years and tabulated in relation to age and parity. Overall
occurrence of repeat breeding, prolonged oestrus and occurrence of prolonged oestrus among
repeat breeder animals was 25.96 per cent, 25.86 per cent and 55.42 per cent, respectively.
Occurrence of repeat breeding, prolonged oestrus and repeat breeding among prolonged oestrus
exhibiting animals among cows was 27.35, 30.29, and 61.58 per cent, respectively. Occurrence
of repeat breeding, prolonged oestrus and repeat breeding among animals exhibiting prolonged
oestrus, among heifers was 23.07, 16.66, and 40.27 per cent, respectively. Among cows, the
occurrence of repeat breeding was highest in the age group of 2-4 years and occurrence of
prolonged oestrus among repeat breeders was highest in the age group 8-12 years. |
| Constraints in participatory management perceived by the inhabitants of human wildlife conflict (HWC) affected areas in Kerala | Author : P.Vinoth, T.S.Rajeev, R.S.Jiji, R.Senthilkumar, V.L.Gleeja | Abstract | Full Text | Abstract :Human-Wildlife Conflict (HWC) can be explained as an interaction between humans and
wildlife where negative consequences, whether perceived, exists for one or both the parties when
the action of one has an adverse effect on the other. The human population residing the forest
buffer zones sharing a common geographical border with it are considered to be more affected
with HWC. These populations encompassing the tribal and non-tribal communities usually manage
the HWC by external assistance and internal efforts by the affected one. The present study was
conducted in such a community so as to identify the above type of affect to identify the constraints
in management of HWC encountered by tribal and non-tribal the inhabitants associated with
the Eastern Palakkad forest circle of Kerala state in India. A total of sixty respondents including
thirty non-tribal and tribal families each from the affected people were purposively selected for
study various division of Palakkad forest area. The responses were recorded initially with group
discussion, pilot study etc., and the final schedule was used as the scale with final statement to
analyse the constraints of the respondents using Garret ranking method. The constraints faced by
encountering HWC and implementing control measure. Most of the non-tribal and tribal respondents
perceived HWCs to be caused by water scarcity during the summer period and inadequate food
availability due to climate change and deforestation, shrinkage of grassland/pasture land, lack of
proper barriers (solar fence, trench) and proximity to forest land as the major constraints.

| Clinicopathological profile of Babesia canis vogeli infection in dogs | Author : Ancy Thankachan, K.Vinodkumar, ShymaV.H, R. Asha, K.Vijayakumar | Abstract | Full Text | Abstract :The clinicopathological profile of Babesia canis infection in dogs presented to University
Veterinary hospital, Kokkalai was studied. Eight animals with clinical signs of babesiosis like
pyrexia, anorexia, amaemia and lethargy and found positive for Babesia piroplasms in blood
smear were included in the study. The organism was identified as Babesia canis vogeli by PCR.
Haematological analysis showed highly significant alterations in granulocyte count, monocyte
count, Mean Corpuscular Volume (MCV), Mean Corpuscular Haemoglobin (MCH), platelet count
and significant alterations in total RBC count. Systemic inflammatory response syndrome (SIRS),
as per the classification of Matijatko et al. (2010) was noticed in two out of eight animals. This
indicate that B. c. vogeli organisms which are considered to be benign in some parts of the world
can cause severe complications in a different geographical location. |
| Assessment of foetal lung surfactant in amniotic fluid of dogs by bubble test, to evaluate foetal maturity | Author : D.S. Suprith, M.P. Unnikrishnan, M.O. Kurien, B. Bibin Becha and Binu K. Mani | Abstract | Full Text | Abstract :Study was conducted to determine the reliability of bubble test for assessment of lung
surfactant in amniotic fluid and its application in clinical level to judge the foetal maturity. Amniotic
fluid samples were collected from the foetuses of dogs undergoing elective caesarean section
(Group I) at term and from the foetuses of dogs undergoing ovariohysterectomy at different stages
of gestation, following misalliance (Group II). All the samples from neonates of Group I were found
positive for bubble test, with variable grades ranging from two to four. All the samples from Group
II foetuses were found negative for bubble test, with grade of zero and one. The results signify the
presence of adequate foetal surfactant in amniotic fluid of mature foetuses when compared to that
of immature foetuses and also suggest the potential practical utility of bubble test for foetal maturity
assessment, particularly for timing elective induction of whelping or timing of caesarean delivery |
| Comparison of endometrial cytology and transrectal ultrasonography for the diagnosis of subclinical endometritis | Author : Gayathri Prathap, Shibu Simon, M.O Kurien, B. Bibin Becha, Surej Joseph Bunglavan, Niyas Emadudeen, Gleeja V. L. | Abstract | Full Text | Abstract :The objective of the present study was to compare the efficacy of endometrial cytology
(EC) and uterine echobiometry by transrectal ultrasonography (TRUS) for the diagnosis of
subclinical endometritis (SCE) in crossbred dairy. A total of 20 crossbred cows, at 30 and 40 days
postpartum (DPP), without any clinical signs or abnormal discharge were subjected to transrectal
ultrasonography (TRUS) and endometrial cytology (EC) examination. Among the TRUS parameters,
uterine horn diameter (UD) was found to be least useful in the diagnosis of SCE. Cervical diameter
(CD) also had poor to moderate sensitivity when compared to EC and less accurate in diagnosing
SCE. Fluid in uterus (FIU) had more sensitivity than UD and CD for the diagnosis of SCE but its
presence is dependent on the stage of oestrous cycle. Hence, when TRUS is used as a supporting
diagnostic aid along with EC, it has promising value in the diagnosis of SCE. |
| Comparative analysis of closed and open-cervix canine pyometra | Author : V.K. Vidya, M.P. Unnikrishnan, M.O. Kurien, C. Jayakumar and Surya Sankar | Abstract | Full Text | Abstract :Canine pyometra is the most common uterine disease in intact, sexually mature female
dogs. The disease is broadly classified as open and closed type, based on the patency of
cervix. The study was conducted to evaluate the changes in clinical, physiological and haematobiochemical
parameters in open and closed-cervix pyometra. Physiological parameters were not
altered among pyometra-affected dogs. Vomiting, dehydration and dullness were more frequently
noticed in open-cervix pyometra cases. Significantly higher total leucocyte count and band cell per
cent and significantly lower total erythrocyte count was recorded among dogs with open-cervix
pyometra than closed-cervix pyometra. The present finding is contradictory to most of the previous
reports. |
| A study on the factors influencing resumption of postpartum ovarian activity in crossbred cows | Author : K. Sonam, K. Promod, Leeba Chacko, K.C. Bipin, Lijo John | Abstract | Full Text | Abstract :The aim of the study was to identify the factors influencing postpartum resumption of
ovarian activity in crossbred cows. Sixty crossbred cows on day 30 postpartum were selected and the
details of age, parity, milk yield, peripartum and postpartum complications were recorded. Animals
were examined per rectally from 30 to 90 days postpartum at 12 days interval for the presence of
corpus luteum (CL) of any stage during the period of study. Serum progesterone concentrations
were estimated and cows which resumed ovarian activity (progesterone concentration >1 ng/mL)
at early and late postpartum periods were identified. Association of age, parity, BCS, milk yield and
reproductive complications with postpartum resumption of ovarian activity (ROA) at varying periods
was analysed. No significant association between ROA and variables such as age, parity. milk
yield and reproductive complications were observed. BCS was significantly (P<0.01) associated
with ROA. The higher number of animals with postpartum complications belonged to not resumed
period than that of early and late resumed periods. The odds ratio for BCS indicated 6.46 times risk
for ROA for every unit increase of BCS. |
| Physico-chemical and structural attributes of meat from young and spent buffaloes | Author : S. Kiran Kumar, V.N. Vasudevan, S.Prajwal, T.Sathu, A. Irshad, C.Sunanda, S.Silpa, and M.Pavan | Abstract | Full Text | Abstract :The current study was carried out to determine the physico-chemical and structural
attributes of buffalo muscles from two anatomical locations obtained from animals belonging to two
different age groups. Six each of young (2-4 years) and spent (8-10 years) buffaloes were procured
from University Buffalo Farm, Mannuthy and were slaughtered scientifically at Meat Technology
Unit, Mannuthy. Each carcass was electrically stimulated. The longissimus dorsi (LNG) and Biceps
femoris (BIF) muscles were harvested, connective tissue and fat removed, aged for 72 hours at
4±1°C and analysed for the parameters. The ultimate pH values did not differ significantly between
the muscles as well as the age groups. Hunter L* and a* values were significantly different between
the muscles. Hunter L* and b* values had significant difference between the age groups. Myofibrillar
fragmentation index and Warner bratzler shear force of LNG and BIF were significantly different
between age groups as well as between muscles. With respect to structural characteristics, no
significant variation was noticed in sarcomere length between the muscles and the age groups.
Between two age groups, muscle fibre diameter of samples from spent animal group showed
significantly higher values. Thus, the results indicate important differences in the quality attributes of
buffalo meat of two different age groups, which may be reflected in their palatability and processing
properties. |
| Anatomical observations on the hair distribution patterns in the deer, goat and sheep | Author : S. Maya, N. Ashok, K. M. Lucy, V. R. Indu, A. R. Sreeranjini, N. S. Sunilkumar and K.B. Sumena | Abstract | Full Text | Abstract :Hair distribution patterns in the deer, goat and sheep were studied using skin samples collected
from spotted deer brought for post mortem at College of Veterinary and Animal Sciences, from
the Thrissur zoo and forest department and from goats and sheep freshly slaughtered at the
Meat Technology Unit, Mannuthy. Samples of 1cm3 were collected from 27 regions of skin, viz.
muzzle, infraorbital, horn glands, dorsal face, lateral face, ventral face, ear pinna, dorsal neck,
lateral neck, ventral neck, dorsal abdomen, lateral abdomen, ventral abdomen, dorsal forelimb,
palmar, dorsal hindlimb, plantar, interdigital part of fore limb, interdigital part of hind limb, forelimb
foot pad, hindlimb foot pad, inguinal, preputial scrotal regions of male dorsal thorax, perineum
and dorsal nasal regions. The hair arrangement in the three species was simple, but arranged in
groups. Mostly two to three hairs formed a group and they emerged out very closely but not from
a single orifice unlike in the case of compound hairs. The muzzle region lacked hair on the rostral
aspect and sparse wool hairs were found on the dorsal surface. Dorsal nasal and carpal regions
consisted of dense population of short, stout hairs. Maximum hair density per microscope field
under low power was noticed in the lateral aspect of neck, dorsal abdomen, palmar, interdigital
aspect of hind limb, lateral abdomen and dorsal aspect of hind limb in deer. Hair was absent in
the muzzle followed by dorsal face region in all three species in the present study. Maximum hair
density per microscope field under low power was noticed on the dorsal aspect of fore limb, palmar
aspect, pinna of ear, dorsal abdomen and interdigital space of hind limb in goat with minimum
hair distribution on the ventral abdomen followed by lateral face region. Maximum hair density per
microscope field under low power was noticed on the dorsal aspect of neck, interdigital space
of fore limb, lateral aspect of neck and infraorbital in sheep with minimum hair distribution on the
ventral abdomen, dorsal face and lateral face. In general, density of hair distribution was more in
the deer than the goat and sheep. |
| Effect of coenzyme q10 supplementation on total antioxidant status and lipid peroxides levels in dogs with chronic valvular heart disease | Author : K. Revathi, N. Madhavan Unny, Usha Narayana Pillai, R. Uma and S. Ajithkumar | Abstract | Full Text | Abstract :Oxidative stress management has been found to have beneficial effects in the management
of several disease conditions. A study was conducted to evaluate the efficacy of Coenzyme Q10
supplementation on the total antioxidant status and lipid peroxides levels in dogs with chronic
valvular heart disease. Total antioxidant status was measured by Ferric Reducing Antioxidant Power
assay and level of lipid peroxides in serum was determined by estimating malonaldialdehyde level.
Ten dogs with chronic chronic valvular heart disease were administered with coenzyme Q10 @
45mg q12h orally for 60 days along with the treatment for management of valvular heart disease. A
significant decline in Ferric Reducing Antioxidant Power value was recorded at the end of the study.
The malonaldialdehyde levels declined in animals with chronic valvular heart disease by day 60,
though reduction was not statistically significant. The administration of Coenzyme Q10 in chronic
valvular heart disease may be beneficial in improving the quality of life of the patient. |
| Influence of thermal stress on feed intake and body condition score during early postpartum period of crossbred cows in Kerala | Author : C. Ibraheem Kutty, C. P. Abdul Azeez, K. Promod, B. Bibin Becha, C. Sunanda , S. Lasna and K.S. Anil. | Abstract | Full Text | Abstract :Increased milk production and environmental alterations caused by climate change
makes dairy animals highly vulnerable to Thermal Stress (TS). Cross bred cattle shows some level
of adaptation, characterized by reproductive performance of low level, almost uniformly throughout
the year. Hence, objective of the present study was to find out the pattern of feed intake and body
condition score of cross bred cows in the context of adaptation to TS across seasons prevailing in
Kerala.
The study was carried out at Livestock Research Station, Thiruvazhamkunnu, Kerala, in
22 post partum cows between Day 7 and Day 135 of calving. Daily intake of concentrate and
weekly body condition score (BCS) were recorded. Blood samples were collected from 10 cows
every week for estimation of thermal stress indicators and the climatic variables were recorded
daily. Data were analyzed for monthly and seasonal variations and correlations between each
other.
Temperature Humidity index (THI) and other climatic variables showed exposure of the
animals to TS throughout the year. During summer months, ambient temperature and THI were
significantly higher to cause moderate TS. Feed intake, BCS and cortisol levels were significantly
high during summer, even though there was no significant correlation with climatic stress factors.
HSP 70 was elevated throughout the year and significantly high during the period of moderate THI,
indicating adaptation to TS. It is concluded that higher feed intake and BCS during summer months
is attributable to TS adaptation because of continuous exposure across many years. |
| In vitro antimicrobial activity of lemongrass (Cymbopogon flexuosus) oil and citral against Methicillin Resistant Staphylococcus Aureus (MRSA ) from bovine mastitis | Author : S. Jisha, R.S. Suja, J. K. Bibu, S. Surya, R. Ambily, J. Reni, Thresia, V.K. Vidya , P. Gayathri and P. T.A. Usha | Abstract | Full Text | Abstract :The mounting tide of bovine mastitis by methicillin-resistant Staphylococcus aureus
(MRSA) poses serious threat to efficacy of antibiotic treatment. Therefore, plant derived essential oils
and their constituents are gaining great importance in the recent times as promising antimicrobial
agents. Hence the present study was conducted to evaluate antibacterial activity of lemongrass
oil (LGO) and its active principle, citral against methicillin and oxacillin resistant Staphylococcus
aureus (MRSA) isolated from bovine mastitis cases. Among the 16 S. aureus organisms isolated,
six isolates identified as MRSA by antibiogram against methicillin and oxacillin were selected for
further study. The findings of the study indicated significant antimicrobial activity of LGO and citral
as evident from their minimum inhibitory concentration (MIC) and diameter of zone of inhibition
values. |
| Effect of dietary incorporation of ksheerabala residue on growth performance in wistar rats | Author : Deepak Chandran, K. Jasmine Rani, K.Shyama and K.Ally | Abstract | Full Text | Abstract :Ksheerabala residue is a by-product obtained during the preparation of ksheerabala
oil which is made by incorporating bala (Sida cordifolia), cow milk and gingelly oil (Sesamum
indicum). This residue is available in considerable quantity and many farmers use this byproduct
for feeding livestock. But the level of incorporation and the effect of Ksheerabala residue on growth
in rats are not yet well studied. Hence, the present study was planned to evaluate the effect of
dietary incorporation of Ksheerabala residue as a feed resource in the diet of Wistar rats on their
performance. Twenty-four male Wistar albino rats weighing 80 ± 5g were used as experimental
animals and were allotted randomly to two treatments of six replicates each. Group 1 was fed
basal diet as per BIS specification (control-T1) and other group was fed a diet containing 5 per
cent Ksheerabala residue (T2). The average body weight, body weight gain, dry matter intake,
haematological and biochemical parameters were found to be similar in both the groups (P >0.05).
The results of the present study indicate that Ksheerabala residue can be included in the rat ration
up to five per cent level without any adverse effect on their growth performance. |
| Effect of dietary incorporation of ksheerabala residue on nutrient digestibility and blood biochemical profile in Malabari kids | Author : T.J Roshma, K. Ally,Thirupathy Venkatachalapathy, K. Shyama and K. George Sherin | Abstract | Full Text | Abstract :An experiment was conducted with eighteen weaned Malabari kids of three months of
age for 90 days to assess the effect of dietary incorporation of Ksheerabala residue on nutrient
digestibility and blood biochemical profile in goats. Kids were divided into three groups (T1, T2 and
T3) as uniformly as possible with regard to age, sex and body weight and were offered kid starter
containing Ksheearabala residue at 0, 10 and 20 per cent, respectively. Kid starters were made
isonitrogenous and isocaloric (24 per cent CP and 70 per cent TDN). Kids were fed as per ICAR
standards (Ranjhan, 1998). Green grass was offered as the sole source of roughage. Data on
digestibility of nutrients and haematologcal parameters like haemoglobin, plasma protein, serum
calcium, serum phosphorus, serum cholesterol and triglycerides were the criteria employed for
evaluation and they did not show any significant difference (P >0.05) among the groups. It could be
inferred that digestibility of nutrients and haematological parameters of kids were not influenced by
the inclusion of Ksheerabala residue in kid starter. |
| Exome wide variant discovery by next generation DNA sequencing in Vechur cattle of Kerala | Author : R. S. Reshma, T. V. Aravindakshan, G. Radhika, T. Naicy and K. Raji | Abstract | Full Text | Abstract :Vechur, the native cattle breed of Kerala, India is well-known for economically
valuable phenotypic traits like disease resistance, adaptability to hot and humid tropical
climatic conditions, low feed requirements and high quality milk. However, genomic information
underlying these traits is rare. In the present study, the whole exome sequencing of a Vechur
cow using Illumina HiSeq 2500 platform is reported. Comparison of sequences with Bos
taurus reference genome assembly (UMD 3.1) identified 1,716,847 variants including 1,578,749
Single Nucleotide Polymorphisms and 138,098 Insertion/Deletions, of which 359,034 variants
(20.91%) were novel. Detailed annotation of the identified variants showed that majority were
situated in the intergenic region. Out of the 724,808 variants found inside the gene region,
107,880 were exonic variants. In the exonic variant, substantial proportion of non-synonymous
(34.83%), frameshift (12.47%), nonsense (0.3%), start loss (0.06%) and stop loss (0.0009%)
variants were identified. This information will provide a better understanding of genetic
differences responsible for the peculiar phenotypic traits inherent to Vechur cattle. |
| Comparative analysis of milk quantity and quality in native goat breeds of Kerala | Author : K. Mathivathani, G. Radhika., T.V. Aravindakshan., R. Geetha and Marykutty Thomas | Abstract | Full Text | Abstract :Goat rearing occupies an important place in augmenting the economy of our country. In
India there are 23 well defined goat breeds and Kerala has two native breeds namely Malabari
and Attappady Black, which vary significantly in milk production. Data on quantity of milk was
collected from 100 Malabari and 70 Attappady Black goats. There was a significant influence of
breed (p=0.01) and parity (p=0.05) on milk production. The average milk yield of Malabari goats
was, 558.94 ± 4.21 ml per day, while for Attappady Black it was 340.22 ± 4.45 ml per day. Milk
samples were collected from 54 Malabari and 35 Attappady black goats and significant difference
was observed in fat per cent between two groups. Double digest restriction associated DNA
sequencing (ddRADseq) is a modern reduced representation sequencing technique which is a
powerful and inexpensive approach for identification of Single Nucleotide Polymorphisms (SNP)
across populations. This technique was applied on two groups of Malabari and Attappady Black
goats with differing milk production and the preliminary evaluation of results revealed SNPs in five
major genes affecting milk production. |
| Response of crossbred cattle in terms of respiration rate and rectal temperature to maximum and minimum THI period in Kerala | Author : N.V. Jisha, G. Girish Varma, V. Beena, A. Prasad, V.L. Gleeja, K. Karthiayini and V. Sejian | Abstract | Full Text | Abstract :The observation indicated that from
THI 82 to 86 the body of the animal could
maintain body temperature by physiological
means of thermoregulation primarily by
increasing respiration. Rectal temperature
showed a positive correlation when THI reaches
86 and rectal temperature started increasing at
ambient temperature of 340C and THI 86. But
beyond 86 all these mechanisms failed and
body temperature started rising. The relative
humidity affects evaporative cooling negatively
when it cross limit. This limit is very important
to adopt management practices and could be
identified by doing experiments at different RH
levels using a climate chamber. The absence of
correlation between THI and AH is also pointing
to the fact that temperature and humidity affect
the evaporative mechanism independently. |
| Characterization of malabari goat lactoferrin and its pepsin hydrolysate | Author : Deepak Chandran, Uma Radhakrishnan and Linu Eldho | Abstract | Full Text | Abstract :Lactoferrin, a minor whey protein present mainly in milk as well as in small quantities in
most of the secretions of the body, has a wide range of biological activities to its credit including
antimicrobial, antioxidant, anticancer and immunomodulatory properties. A low molecular weight
peptideisolated from the pepsin hydrolysate of lactoferrin called aslactoferricin B, has been found
to be more functionally active than its parent compound. The present work focussed on the isolation
of lactoferrin from the colostrumof Malabari goats by cation exchange chromatography, followed
by the assessment of its molecular weight by SDS-PAGE andits characterization by dot blot assay
and western blotting.The concentration of lactoferrin as estimated by Lowry’s method was found to
be 15.103 mg/L of colostrum. Lactoferrin was hydrolysed by treatment with three per cent porcine
pepsin under acidic conditions to form lactoferrin pepsin hydrolysate. The results of this study point
to a single one step method to obtain pure lactoferrin from goats and further preparation of its
pepsin hydrolysate. |
| Detection and vp6 gene based molecular characterization of rotaviruses of pigs in Kerala | Author : G. Logeshwaran, Chintu Ravishankar, D Nandhakumar, Stephy Rose Sebastian, K. Sumod, T. R. Jayakrishnan, Reghu Ravindran and Koshy John | Abstract | Full Text | Abstract :Rotaviral enteritis is a common condition observed in farm animals especially piglets and
calves. Though the presence of porcine rotaviruses (PRV) have been reported in pigs in Kerala, no
study has been conducted to characterize them. This paper reports the finding of a study conducted
to detect and characterize PRV based on VP6 gene. A total of 87 samples collected from cases
of piglet diarrhoea were subjected to VP6 gene based reverse transcriptase polymerase chain
reaction (RT-PCR) and five (5.74 per cent) was found to be positive. All the positive samples were
from Palakkad district. On analysis of the nucleotide sequence it was observed that the viruses
belonged to inner capsid type I5 and I14 indicating diversity in the PRV prevalent in Kerala. |
| Higher concentration of haptoglogin indicates transient inflammation and negative energy balance in transition cows | Author : S.V. Vasudhar Bhat, J.P. Anisha, M. Shynu, K.K. Jayavardhanan and V. Ramnath | Abstract | Full Text | Abstract :Haptoglobin is an acute phase protein that is of diagnostic significance in dairy cattle. In
the present study, haptoglobin level was assessed during the periparturient period in 15 clinically
healthy pregnant cows. The mean concentration of haptoglobin during transition was found to be
5.60 ± 0.54 mg/dL, whereas the concentration during the period immediately before and after
transition was 4.80 ± 0.59 mg/ dL. The concentration obtained was greater than the reported
concentration of 2mg/dL or less, in healthy ruminants. The higher concentrations observed were
also associated with a higher concentration of serum non-esterified fatty acids of 0.576 ± 0.10
mmoles/L during transition and 0.328 ± 0.03 mmoles/L immediately outside the transition period.

| The occurrence of antibiotic residues in pooled raw cow milk samples of Palakkad, Kerala | Author : M.H. Asif, C. Latha, K. Vrinda Menon, Deepa Jolly, Suresh N. Nair and C. Sunanda | Abstract | Full Text | Abstract :Antibiotic residues in milk pose a potential risk to the health of consumers and are of
public health significance due to the dissemination of antimicrobial resistance. The present study
was conducted to assess oxytetracycline and enrofloxacin residues in pooled raw milk samples in
Palakkad district. A total of 120 pooled raw milk samples collected from five co-operative societies
in Palakkad district were screened by Microbial Inhibition Assay (MIA). The positive samples were
subjected to charm assay to determine whether the level of antibiotic residues viz., oxytetracycline
and enrofloxacin were within or above Maximum Residual Limit (MRL). Of the 120 samples
screened using MIA, 14 samples (11.67 per cent) were found to be positive for antibiotic residues.
The occurrence of tetracyclines and enrofloxacin residues in pooled raw milk samples was found
to be respectively 3.33 and 4.16 per cent using charm assay. Statistical analysis using chi-square
test for multiple proportions revealed that the occurrence of antibiotic residues between the cooperative
societies did not differ significantly (p > 0.05). The occurrence of antibiotic residues in
milk necessitates prudent use of antibiotics, observance of the withdrawal period and monitoring
system for antibiotic residues in foods of animal origin |
| Clinico haematological studies on xenotransfusion in cats | Author : A. P. Sahla Shaheena, N. Madhavan Unny, N. P. Usha, S. Ajithkumar, L. Bindu and C. Sunanda | Abstract | Full Text | Abstract :The present study was conducted in anaemic cats presented to the University Veterinary
Hospital, Kokkalai and Teaching Veterinary Clinical Complex, Mannuthy. They were subjected to a
detailed physical examination, blood smear and faecal sample examination and haematology to
reach an etiological diagnosis and to assess the severity of anaemia. Xenotransfusion with dog
blood was carried out in 10 severely anaemic cats. Clinical outcome and variation in haematological
parameters before and 24 hours after the transfusion was evaluated. |
