The vegetal ash can become an alternative for fertilization of vegetables in the metropolitan region of Manaus, Amazonas. The objective of this work was to evaluate the effect of doses of vegetal ash on the growth and production of cress (Barbarea verna) and arugula (Eruca sativa). The vegetal ash presented high levels of alkalinity (pH 11.23), base saturation (100%) and cation exchange capacity (15.41 cmolc dm-3 ), with a high potassium content (4.950 mg dm-3 ). However, under the conditions in which the experiments were conducted, the tested doses of vegetal ash had no additional beneficial effects on the development of plants.

The objective of this study was to conduct a retrospective study from July 2017 to July 2018 on the anatomopathological changes observed in post-mortem examination in slaughterhouses in Manaus-AM. Among the evaluated organs, 23% of the pieces were found to be condemned, with 54.29% represented by lung condemnations, followed by 12.78% of legs, 9.91% of kidneys, 5.20 % of head, 3.44% of intestines, 3.06% of tongue, 2.58% of heart, 1.39% of stomachs and 1.31% of livers. The organs with the greatest number of convictions were lungs and paws, and possibly these convictions occurred due to failures during pre-slaughter or even during slaughter.

The effect of supplementation with leucaena hay in partial replacement with the babassu pie, on grazing behavior, average daily gain (ADG) and infection by gastrointestinal nematodes in goats was evaluated. 15 male goats were arranged in DIC, factorial 3x2, with three proportions of leucaena hay (0, 20 and 40%) in two grazing cycles and five replications. The grazing cycle influenced the times for grazing and rumination. The supplementation interfered in leisure activity and supplement intake, variable also influenced by cycles. ADG was higher in cycle 1 and as well as the degree of nematode infection, it was not influenced by supplementation.

The agronomic traits, morphological composition and forage yield of seven forage sorghum genotypes were evaluated in two municipalities of Western Bahia, between January and May of 2017. A randomized complete block design with three replications was used. The genotypes tested were: Podium, Formoso, BRS-610, IPA-1011, IPA-467, SF-15 and SS-318. The genotypes SF-15 e IPA-467 were taller. BRS-610, Podium and SS-318 had greater averages in the length and diameter of the panicle. For Western Bahia, BRS-610 and Podium hybrids are recommended due to greater forage yields and panicle percentage.

This study aimed to investigate the presence of components, mast cells and myofibroblasts, to develop joint contraction in sheep and evaluate a potential as an experimental model for the development of this problem. Fifteen capsules of Santa Inês ewe lambs were used to localize the a-SMA protein, identifying a presence of myofibroblasts by the immunohistochemical technique, and mast cells by the Toluidine Blue staining under a light microscope. In the joint capsules, rare mast cells were stained. Studies on joint capsule lesions of sheep should be conducted to confirm the presence of myofibroblasts and joint contracture development.

Livestock is one of the main responsible for the Brazilian GDP, standing out in cattle ranching and one of the great problems of the producers, are degraded pastures. The objective of this work is to evaluate the relationship of different P sources and different application times in the reformulation of degraded pasture areas, using Brachiaria brizantha cv. Marandu. The experimental design was (DBC) in factorial scheme 5x3, being 5 treatments, control and 4 sources of P and three times of application. The chemical fertilizer MAP and reactive natural phosphate presented better performance. Early liming contributed to improved forage performance in the study.

The propagation by cutting comes as an alternative to guarantee the production of uniform and genetically homogeneous seedlings. Cutting of Annona squamosa (L.), Annona muricata (L.) and Atemoya Annona cherimola x Annona squamosa (L.) were collected at two times of the year, 15cm long, with two pairs of leaves cut in half. The cuttings were treated by immersing their base for 5 seconds in indolbutiric acid and naphthaleneacetic acid solutions at concentrations of 0, 0,25%, 0,50%, 0,75% and 1%, and then were packed in styrofoam polyethylene trays containing mix of substrate, maintained for 120 days under intermittent misting. Indolbutyric acid and naphthaleneacetic acid increase the rooting percentage, number and root length at concentrations of 0.50% to 0.75% respectively. The for the best season, highlights the summer.

Currently it has been observed the need for alternative botanical sources to meet the demand of potato starch manufacturers, mainly in the period between crops that the industry is idle. In Mato Grosso do Sul arrowroot can become an alternative source to meet this seen demand for the extraction of starch using the same physical structure already installed, and its starch has high commercial value because of its peculiar features required both in the market national and international, but to reintroduce that grow in the field of these agro-industries requires a better knowledge of nutrition to better understand your needs regarding macronutrients and micronutrients for its development, this work focused on checking the phosphorus doses of contribution to production arrowroot rhizomes. They evaluated several plant points such as diameter, mass shoots, root mass, shoot dry weight, root dry mass and mass of the rhizomes. It was found that the doses of P significantly influenced culture, it was observed that the higher dose of P of all varieties had greater weight of the plant with emphasis on the dose 320 kg ha-1 , in which the plants had an average weight 1.29 kg.

The aim of this study was to analyze a case of rabies observed in a beef that was served in a property in the city of Fortaleza -CE.

After death, central nervous system material was collected (CNS) and sent to the Central Laboratory of Public Health of Ceará, where it was confirmed the diagnosis of rabies.

The objective of this work was to evaluate morphological differences and genetic divergence among the Creole corn so that they can serve for the cultivation of producers in the region of Couto Magalhaes de Minas MG. The experiment was conducted at the Rio Manso Experimental Farm, Federal University of the valleys of Jequitinhonha and Mucuri, during the 2017/18 harvest, being studied six varieties of Creole corn, two improved varieties and two commercial varieties. Thirteen characteristics were evaluated: leaf, stem and flowering. The varieties of Creole corn showed genetic divergence, being generally discriminated by the genetic origin and the morphological characteristic that contributes most to the divergence is the mean height of the spike insertion.

The objective of this work was to perform physicochemical evaluations of genotype at mature and mature maturation stages. Evaluations were made in fruit pulp and seed, such as pH, acidity, vitamin C, instrumental color, total phenolic compounds, carotenoids, flavonoids and antioxidant activity. The physicochemical aspects resulted in values that varied for the pulp and seed of the green and mature fruit, respectively: pH (4.12, 3.93, 5.05; 4.38), acidity (0.45, 0.51, 0.89, 0.27 g/100g). The vitamin C ranged from 16.67 à a 50.00 mg/100g, phenolic compounds ranged from 91.05 to 166.80 EAG/100 g, antioxidant activity (20.80, 54.87, 53.76, 50.22%), besides presenting carotenoid and flavonoid contents.

The objective of this work was to evaluate the effects of increasing doses of urea (0, 2, 4, 6, and 8%) on the chemical composition, in situ degradability, intake and performance of feedlot beef cattle. CP was increased, and NDF and ADF were decreased by increasing the doses of urea. Ammoniation improved DM and NDF degradability. However, intake and performance were reduced when higher doses of urea were used. Ammonization with 4% of urea propitiated the improvement of nutritive value of cotton gin trash and the greatest performance of feedlot beef cattle.
