| ABSTRACT We aimed to evaluate the effects of glyphosate as a chemical desiccant on the nutritional quality, fermentation pattern, and aerobic stability of wilted black oat (Avena strigosa Schreb) silage. Black oat sowing occurred in the first fortnight of May 2013. Desiccant application took place when oat reached milky/dough grain stage (96 days after planting). Glyphosate dosages evaluated were 0, 500, 750, 1000, and 1250 mL ha−1. Three days after desiccation, all treatments were ensiled, and the silos were kept stored for 150 days. A completely randomized design was used, and all statistical procedures were performed by means of Bayesian Inference. Treating herbage prior to ensiling from 500 mL ha−1 glyphosate increased dry matter and organic matter... |

| ABSTRACT The objective of this study was to evaluate the effects of supplementation of two different enzymatic complexes, fibrolytic (NSPases) or amylolytic (EXP3066) enzymes, on growth performance, digestibility, behavior, and carcass characteristics of feedlot cattle. Thirty-six ½ Angus yearling bulls with an average initial weight of 391±5.0 kg were used in this experiment blocked by weight in a completely randomized design divided in three treatments: control, NSPases, and EXP3066. The basal diet was composed of 85% whole corn grain and 15% nucleus. NSPases increased average daily gain on days 63 and 84, and gain:feed ratio on days 42, 63, and 84. Total carcass weight and carcass daily gain were improved by 4.8% and up to 6.0% with EXP3066 and NSPases... |

| ABSTRACT: Forage conservation in silos depends on the efficiency of silo sealing, among other factors, to minimize aerobic deterioration and consequent qualitative and quantitative losses in silage. Thus, the aim of the present study was to evaluate the effect of two sealing types on dry matter recovery rate, aerobic stability, nutritional composition, and in vitro digestibility of corn silage in bunker silos: 110-µm-thick double-sided polyethylene sealing (conventional sealing) and110-µm-thick double-sided polyethylene sealing superimposed on 111-µm-thick translucent polyethylene sealing (double sealing). There were no significant differences in nutritional composition of silages between conventional and double sealing. However, the double sealing system... |

| ABSTRACT: The use of nitrogen fertilizers in corn crops for silage can improve both production and, theoretically, nutritional quality, especially carbohydrate and protein fractions, thereby optimizing animal production. Thus, the aim of this study was to evaluate the effect of increasing levels of nitrogen fertilization in carbohydrate and protein fractionation on the resulting corn silage (Zea mays L.). Nitrogen fertilization was carried out in the urea form (45-00-00) in V5 stage, at the following doses: T1: 0kg N ha-1; T2: 45kg N ha-1; T3: 90kg N ha-1; and T4: 135kg N ha-1. Crops were harvested at R4 stage and submitted to ensiling in experimental PVC silos. The chemical composition of the resulting silage was evaluated after silo opening. There was no... |
