| The objective was to evaluate the productivity, morphological and chemical composition, in addition to the economic viability of the corn crop (Zea mays L.) for the production of silage under different levels of nitrogen and potassium fertilization in coverage. Treatments consisted of four coverage levels: T1 (217 kg ha-1 N + 137 kg ha-1 K2O); T2 (295 kg ha-1 N + 163 kg ha-1 K2O); T3 (374 kg ha-1 N + 190 kg ha-1 K2O); and T4 (452 kg ha-1 N + 216 kg ha-1 of K2O). It was found that the fertilization level had no effect (P> 0.05) in the parameters related to plant height, height of the first insertion spike and grain production, however, higher (P <0.05) dry biomass production was obtained with 374 kg ha-1 N + 190 kg ha-1 coverage K2O (32,346 kg... |

| Body composition analysis is relevant to characterize the nutritional requirements and finishing phase of fish. The aim of this study was to investigate the relationship between ichthyometric (weight, total and standard length, density and yields), bromatological (fat, protein, ash and water content) and bioelectrical-impedance-analysis (BIA) (resistance, reactance, phase angle and composition indexes) variables in the hybrid tambatinga (Colossoma macropomum × Piaractus brachypomus). In a non-fertilized vivarium, 520 juveniles were housed and fed commercial rations. Then, 136 days after hatching (DAH), 15 fish with an average weight of 37.69 g and average total length of 12.96 cm were randomly chosen, anesthetized (eugenol) and subjected to the first of... |

| ABSTRACT: This research aimed at evaluating the effect of increasing coexistence periods with weeds on the nutritional components of the forage grass Brachiaria brizantha cv. Marandú under pasture renewal conditions. The experiment was arranged in randomized blocks with four replications, and treatments were represented by eight coexistence periods, namely: 0, 15, 30, 45, 60, 75, 90 and 120 days after seedling emergence. A phytosociologic evaluation was performed on the weed community at the end of the coexistence periods; later, weeds were eliminated by an herbicide formulated with aminopyralid+2,4-D (40+320 g L-1) at 2.5 L ha-1, applied in post-emergence. The fodder plants were evaluated at the end of the experimental period as for leaf-stem ratio,... |

| ABSTRACT The objective of this study was to evaluate the performance, carcass characteristics and ingestive behavior of feedlot steers fed with three maize hybrids: Maximus VIP3, Defender VIP and Feroz VIP. The experiment lasted 112 days, weighing animals four times, every 28 days. The experimental diets were formulated and constituted by maize silage and pelletized ration in a 50:50 ratio (dry basis). Regardless of the hybrid used, there was an increase in the intake of dry matter with the advance in feedlot evaluation period (9.15, 9.14, 9.35 and 9.59kg day-1, in the first, second, third and fourth weighing, respectively). The type of maize hybrid silage influenced weight gain of animals differently, with a final mean of 1.413kg for animals fed with... |

| The objective of the experiment was to classify 20 protein co-products and by-products of the biodiesel industry with potential to use in ruminant feeding. The meals evaluated were: cottonseed, canudo-de-pito, crambe, sunflower, castor-oil seeds detoxified with calcium, non-detoxified castor-oil seeds and soybean; and the cakes were: cottonseed, peanut, babassu, crambe, palm oil, sunflower, licuri, macauba seeds, non-detoxified castor-oil seeds, turnip and jatropha. The samples were quantified to determine dry matter (DM), organic matter (OM), crude protein (CP), ether extract (EE), neutral detergent fiber corrected for ash and protein (NDFap), non-fiber carbohydrates (NFC), acid detergent fiber corrected for ash and protein (ADFap), lignin, cutin and... |

| Sweet potato is widely used for human consumption, but has also potential for its use in animal feeding. In this study we evaluated yield and quality as forage of wilted vines of various sweet potato genotypes and selected the most suitable for silage. Fifteen genotypes were evaluated (BD-31TO, BD-26, BD-13, BD-17, BD-22, BD-24, BD-54, BD-56, BD-69, BD-43, BD-44, BD-46, BD-52, BD-35, and cultivar Brazlândia Rosada), in a randomized complete blocks design, with three replications. At harvest we determined the yield of fresh matter and subsequently dry matter of vines. After 190 days of ensilage, we determined the concentrations of dry matter, crude protein, neutral and acid detergent fiber, lignin, ash, soluble carbohydrates in both vines and its silages;... |
