Background： Nutrition is one of the most important factors that affect animal performance, and it therefore also impacts on financial results in beef systems. In this way, finding the best strategy for feeding supplements is of paramount importance. Aiming to evaluate the effect of supplement feeding strategies for beef cows in the last third of gestation, two experiments were conducted. In Experiment 1, 35 pregnant Nellore cows were assigned to a completely randomized design with four treatments： control, which received no supplement; supplementation for the last 30 d of gestation（30-d; 3.0 kg/d）; supplementation for the last 60 d of gestation（60-d; 1.5 kg/d）; or supplementation for the last 90 d of gestation（90-d; 1.0 kg/d）. All supplemented treatments received the same total amount of supplement throughout the experiment： 90 kg（20% of crude protein）. A second experiment（Experiment 2） was delineated to evaluate the effects of the amounts offered in Experiment 1 on intake and metabolism. Four multiparous pregnant Nellore cows were assigned to a 4 × 4 Latin square design, with periods of15 d ***： There was a linear effect of the number of days of supplementation on calving body weight（BW; P 〈 0.05）and a quadratic effect on BW change from parturition to d 31 post-calving（P 〈 0.05）, with cows on the 60-d strategy losing less BW post-calving. No difference was found in offspring birth BW（P 〉 0.10）. A significant linear effect on interval from parturition to conception（P 〈 0.05） was observed, with the highest calving to conception interval being observed in the 90-d strategy. The level of supplementation did not affect forage intake or neutral detergent fiber digestibility（P 〉 0.10）. Nitrogen excreted through urine tended to increase linearly with the level of supplementation（P 〈 0.10）.Conclusion： Providing 1.5 kg of supplement during the last 60 d of gestation improves cow performance after calving, reducing the magnitude of BW lost, and reduces the number of

Introduction: Paraquat (1,1’-dimethyl-4,4’-bipyridine-dichloride) is a herbicide used to combat weeds and improve crop productivity. Its acute toxicity can cause fatal poisoning in humans and animals and several studies have shown a strong correlation between paraquat and Parkinson’s disease. Objective: To determine the concentration of paraquat in different types of rice in Brazil. Method: Paraquat quantification is based on a complexation reaction with sodium dithionite, which generates a blueish color compound, whose absorbance was read in a spectrophotometer at the 600 nm wavelength. Results: Five samples were found to be above the maximum allowed limit, while one sample had a concentration in the upper allowed limit. The method employed did not allow quantification of black rice. Conclusion: There is a need for identification of the type of pesticide used in each examined crop as well as their respective dates of remission in order to improve the safety of agricultural practices.

At semi-industrial scale it was obtained two cheeses, one with aromatic culture (CHN) and the other with also L. helveticus (CHN + LH). Proteolysis during ripening was evaluated using proteolytic indices, electrophoretic profile Urea-PAGE and release of free amino acids. Sensory evaluation was performed by acceptability test. It was observed a 5-fold increase in the fraction corresponding to αs1-I-casein in the CHN cheese and 6.5 times in the CHN + LH cheese and 7.2 and 8.2 increase respectively, for total amino acids. Prato cheese with the adjunct culture showed higher acceptability in terms of overall aroma and flavor.

Unconventional vegetables, in general, are plants that have been largely consumed by the population at some point and, because of changes in eating behavior, now present reduced economic and social expression and have lost ground to other vegetables. The objectives of this study were to perform phytochemical screening of the ethanol extracts of Rumex acetosa L., Tropaeolum majus L., Solanum muricatum, Stachys byzantina K. Koch and Solanum betaceum Cav. and evaluate their antioxidant potentials via the methods involving scavaging of the DPPH free radical and the ABTS radical, phosphomolybdenum and reducing power. In phytochemical screening, five species of unconventional vegetables tested positive for tannins;for sesquiterpene, lactones and other lactones. These tests were positive for Tropaeolum majus L. and Rumex acetosa L., Solanum betaceum Cav. and Solanum muricatum tested negative for steroids. Only Solanum betaceum Cav. gave positive tests for flavonoids. Among the five plant species studied, Stachys byzantina K. Koch presented the greatest antioxidant potential in all the methods evaluated.
