This study analyzed the physiological quality and plant in Eugenia dysenterica DC seeds. The treatments were control, drying, fungicide Cercobin® and thermotherapy. It was identified the genus Aspergillus, Fusarium, Penicillium and Rhizopus associated with seed treatment used as a witness. Drying was not an effective phytosanitary control and caused damage to the physiological quality of seeds. The fungicide was more efficient in the seeds prior to storage. Treatment with thermotherapy annulled the presence of Aspergillus and Rhizopus after 100 days of storage and did not cause significant losses in seed quality when compared with fungicide and witness.

The objective of this revision is to study and compare the effects of the use of different levels and lipid sources in the production and composition of milk in dairy cows. Using lipids aims to increase the productive performance per animal and the energy concentration of the diet to supply the energy deficit at the beginning of lactation and to obtain greater efficiency of milk production. Several sources are used, such as lump of cotton, soybeans, sunflower, vegetable oils and calcium salts of long-chain fatty acids. Recent work suggests higher percentage of fat in the diet ranging from 8-9%. The use of fats in the diet at the beginning of lactation brings benefits in the performance of animals.

The Ralstonia solanacearum is one of the main root pathogens of the tomato in North of Brazil. The control is dificult instead, there are no resistant cultivars and no efficient chemicals control. In this study, the use of wild Solanaceas, cubiu (Solanum sessiliflorum), jurubeba (Solanum viarum) and tomato cultivar Yoshimatsu as rootstockswere evaluated. The cv. Santa Cruz Kada Gigante (SCKG), susceptible to bacterial wilt, were used in the graft and rootstock combinations: SCKG/cubiu, SCKG/jurubeba, SCKG/Yoshimatsu, SCKG/autograft and SCKG ungrafted. Were quantified the incidence and symptom development, height and diameter of plants, numbers of flowers and fruits per plant. Plants grafted on cubiu did not develop symptoms of the disease. Yoshimatsu showed partial resistance and increased growth and productivity in grafted plants.

The present work had as objective the elaboration of a systematic bibliographical revision of articles referring to the ergonomic evaluation in activities of vegetal suppression and discussion of the risk factors. The identification of articles and their inclusion occurred in the period from August to December 2016. The electronic databases used were: SciELO; PubMed; PLOS ONE and Google academic. The searches were conducted through descriptors cataloged in the Descriptor in Health Sciences (DeCS). In view of the complexity and importance of the plant suppression activities being evaluated ergonomically, the extreme need to develop and publish more works in the area in question is highlighted here.

The objective was to evaluate the effect of the addition of different commercial brands of ractopamine hydrochloride on diets for finishing pigs, evaluating performance and carcass characteristics. Thirty-six pigs of the commercial strain Dalland, initial weight of 98.74 ± 0.68 kg were used. Experimental design in randomized blocks with three treatments and six replicates per treatment, two animals per experimental plot. Meat samples - control - or supplemented with 10ppm ractopamine from two laboratories were evaluated with 2 ractopamine hydrochloride. Supplementation of 10 mg / kg ractopamine 28 prior to slaughter was found to have improved feed conversion and carcass characteristics.

Bovine brucellosis is a disease of the reproductive nature. Its preferences for occupational groups cause consequently zoonosis demand for public health organs. Based in that scenery it was measured an occurrence seropositive of animal, as a result, it was subsidized the Program of Estate Control and Eradication of Brucellosis and Tuberculosis of Alagoas. It was started an epidemiological research to estimate the occurrence of bovine brucellosis of state, those databases were referring of 2011 and 2012 years. For the statistical evaluation, Z test method used to analyze for compare two proportion. With level of significance a=0,05. The test revealed that there was a low prevalence of Brucellosis in Alagoas with 0,47% (89) in 2011 and 0,14% (19) in 2012. There was significant difference.

The efficiency of Brazil in the production of sugar and ethanol is unquestionable, however, the challenges still remain for the management of the burning of the straw in the pre-harvest of sugarcane, which has generated negative externalities. Water erosion is one of the most aggressive forms of environmental degradation and which has caused huge losses. This work was carried out in the municipality of Campos dos Goytacazes, RJ, Brazil, in order to estimate soil erosion losses in an area planted with sugarcane under two types of crop management. The Universal Soil Loss Equation (EUPS) was used to obtain the erosion rates and the Replacement Cost Method (MCR) to carry out the economic valuation of the ecosystem service.The results show that the rate of soil loss from sugarcane burned was four times greater when compared to the rate for sugarcane harvested raw for both areas studied. The replacement cost of lost nutrients in the cultivation of sugarcane under harvesting system with previous burning was R$6.73 and R$15.91 per hectare of lowland and coastal tableland, respectively, while in the sugarcane harvesting unburned system the cost per hectare was R$ 1.66 for the lowland and R$ 7.56 per hectare for the coastal tableland. It is concluded that the crop management system influences environmentally the preservation of soil fertility and the cost of fertilization of the crop.

Creole varieties are important for the survival of family farms and because it is a low technology investment, being the seed a potential dispersant of pathogens, the objective was to evaluate the microbiolization with Trichoderma harzianum, compared to the chemical treatment, sanity, germination and vigor of seeds of creole bean varieties "Cavalo" and "Chumbinho" (group type carioca and black, respectively). These were covered with: T1) chemical treatment; T2) biological treatment; and T3) control. The biological treatment (T2) reduced the incidence of fungi associated with the seeds of the studied varieties. However, at the dose of 200 mL of commercial product there was reduction in germination percentage and increase of abnormal seedlings.

The objective of this work was to test the methods for overcoming dormancy, as well as to identify the best time for immersion of tamarind seeds in concentrated sulfuric acid. The maximum potential for emergence is obtained by immersion in concentrated sulfuric acid for 30 minutes or cuts in the integuments. To obtain more vigorous seedlings the immersion method in concentrated sulfuric acid for 30 minutes is the most efficient. The immersion time of tamarind seeds in sulfuric acid should be 36.6 minutes for the greatest emergence and vigor.

The main post-harvest concern is with the processing and storage, which plays a fundamental role, since they seek to guarantee the quality of the product that comes from the field. The storage process is the activity that stores and conserves the grains, aiming to guarantee the quality of the product regardless of the time it is kept in storage (BROOKER, 1992 apud LIMA, 2013). The objective of this work is to monitor the classification, temperature and humidity of soybeans at the Coopergrãos Cooperative, located in Nova Andradina – MS, and how these variables interfere with the quality and longevity of grains stored in silos. The temperatures were obtained through thermometry performed with the Thermo Collector MOD. V5 FOCKINK, where weekly temperatures during the months of May, June and July were monitored for each cable and its respective sensors. During this monitoring period, two samples of soybean grains were collected on different days in June to gauge moisture. The samples were withdrawn with the interval of 20 minutes to representatively express the material present in the silo, and were collected at the end of the conveyor belt. There was no proliferation of microorganisms or insect pests, where the grain mass did not present favorable humidity and the temperature was below the optimum for its proliferation. In the classification, we found the total number of defects above the allowed for soybean, but it was framed as Out of Type which does not prevent the sale of grains for other uses in the commercialization.

The objective of the present work was to evaluate the effect of feeding frequency and percentage of feeding on the zootechnical performance of common carp juveniles (Cyprinus carpio). 192 juveniles were fed extruded rations in a factorial scheme (2 x 4 x 4): two feed frequencies (one and two times a day), four percentages of nutrition (1, 2, 3 and 4%) and four replications. It is recommended for juveniles of common carp, 4% of feeding in two daily food frequencies, due to the best gain of weight.
