| It was evaluated intake, total apparent digestibility, performance and feeding behavior of bovine fed diets constituted of corn silage, crushed sugar cane given fresh or crushed and given 72 hours after storage, ensilaged sugar cane with or without 1% of calcium oxide and concentrate at the proportion of 1% of the body weight. It was used 35 bovines, distributed in a random block design, with 5 treatments and 6 repetitions. The animals were housed in collective stalls with troughs individualized by electronic gates. The animals fed diet with corn silage presented greater intake of all nutrients and greater total digestibility of dry matter, organic matter, neutral detergent fiber and total digestible nutrients, as well as greater weight gain and... |

| Objetivou-se com este trabalho determinar o perfil fermentativo das silagens de quatro variedades de mandioca. No estudo do pH, do nitrogênio amoniacal, dos ácidos orgânicos, do índice de recuperação de matéria seca (MS) e da densidade das silagens, utilizou-se delineamento em blocos casualizados com esquema fatorial 4 × 3, com quatro repetições, sendo quatro variedades de mandioca (Amarelinha, Olho Roxo, Periquita e Sabará) e três frações da parte aérea (planta inteira, sobras do plantio e terço superior). No estudo da perda de matéria seca por gases e efluentes, o esquema fatorial utilizado foi 4 × 3 × 7, com quatro repetições, composto de quatro variedades de mandioca, três frações da parte aérea e sete datas de abertura dos silos (1, 3, 5, 7, 14, 28 e... |

| Objetivou-se avaliar o ganho de peso e as características de carcaça de bovinos Nelore, castrados ou não-castrados, terminados em confinamento. Utilizaram-se 36 animais com 24 meses de idade e peso vivo médio inicial de 445,30 (não-castrados) ou 449,57 kg (castrados aos 400 kg de peso corporal). Os animais foram abatidos aos 50 dias de confinamento, quando atingiram peso vivo médio de 516,30 (não-castrados) e 506,86 kg (castrados). Os animais não-castrados não tiveram aumento no peso vivo final, mas apresentaram maior ganho de peso (1,42 e 1,15 kg). Os pesos de carcaça quente (272,77 e 261,89 kg) e carcaça fria (266,13 e 258,24 kg) não diferiram entre animais não-castrados e castrados. Animais não-castrados apresentaram maior rendimento de carcaça quente... |

| The objective of this study was to evaluate low and high Brix diets, treated or not with 5 g of calcium oxide per kg of natural matter, and corn silage on intake, digestibility and performance of beef cattle. Forty cattle with initial body weight (BW) of 350 kg were used: five composed the control group, 30 were distributed into random blocks (control) and the other five were distributed in a 5 × 5 incomplete Latin square, with the objective of determining digestibility. The 30 animals evaluated for performance were slaughtered and empty body weight (EPW), carcass dressing and meat cuts were determined. The diet with corn silage (CS) presented the best intake of the other ingredients and the best weight gain, except for neutral detergent fiber intake in... |

| It was evaluated intake, rumen and intestinal digestibility and passage and digestion rates in bovines fed diets constituted of corn silage, crushed sugar cane and given fresh, crushed sugar cane and given after 72 hours of storage, ensiled sugar cane with 1% of calcium oxide and with no treatment and a same concentrate fixed at 1% of body weight. All roughage was corrected to contain 10% of crude protein. It was used five rumen-fistulated bovine with average weight of 240 ± 15 kg, distributed in a 5 × 5 Latin square. Abomasum and total fecal collection and two rumen evacuations were carried out in the morning. Animals fed corn silage based diet presented greater rumen digestibility of the protein and intestinal digestibility of the ether extract, greater... |

| The objective of this study was to evaluate the effect of sugar cane ensilage with different Brix degrees, with or without the addition of 0.5% of calcium oxide (lime) on the chemical composition and fermentation losses of silages. A complete random design in a 9 × 2 factorial arrangement was used. Experimental silos were used, ensilage was done every 15 days with Brix measuring, and they were opened after 30 days of fermentation. As the Brix degree of the ensiled material increased, the contents of dry matter (DM) increased and contents of ash, crude protein (CP) and fibers (neutral and acid detergent fiber corrected for proteins - NDFap and ADFap) reduced. After fermentation, DM content of the silage presented a linear increase with the Brix degree... |
