ABSTRACT: The inner bark or less tender sheath generated from industrial manufacture of canned babassu palm (Attalea speciosa) heart is inadequate for human consumption, often being discarded inappropriately and giving rise to environmental pollution. Accordingly, the aim of this study was to assess the intake and digestibility in sheep fed on silage of the agro-industrial co-product of babassu palm (ICBP)enric...
Avaliou-se as características morfogênicas do Capim Tamani (Panicum maximum cv. BRS Tamani), estabelecido com sementes inoculadas ou não com Azospirillum brasilense em função de fontes de fosfato (superfosfato triplo e fosfato natural reativo de bayovar) e doses crescentes de nitrogênio (0, 75, 150, 300 e 600 kg ha-1) em delineamento inteiramente casualizado, organizado em esquema fatorial 2 x 2 x 5 com 4 repet...
The objective of this study was to estimate requirements of energy, protein and macrominerals of young Nellore/Holstein crossbreds bulls supplemented on pastures of Brachiaria decumbens Stapf. Thirty-five young bulls, at 8.53±0.18 months of age and with initial body weight of 230.6±6.1 kg were used. Ten animals were slaughtered as reference, in different weight range, and the other animals were slaughtered at t...
Avaliaram-se o desempenho produtivo e as características nutricionais em tourinhos Nelore em fase de recria, não-castrados, recebendo diferentes ofertas de suplementos em pastagem de Brachiaria decumbens, de julho a setembro de 2006. A área foi dividida em cinco piquetes de 2,0 ha, com disponibilidade média de matéria seca (MS) e matéria seca potencialmente digestível (MSpd) de 3,88 e 2,22 t/ha, respectivamente...
Sixty 18-month-old steers (20 Nellore, 20 F1 Simmental × Nellore and 20 F1 Angus × Nellore with average body weight of 265.6±6.4 kg; 325.3±4.7 kg and 324.6±6.0 kg, respectively) were used. The effects of feeding regime and genetic group on physical carcass composition, empty body composition, composition of the gain, as well as the pattern of tissue deposition were evaluated in this trial. The interaction betwe...
This trial was conducted to evaluate some beef quality attributes of Nellore, F1 Simmental × Nellore and F1 Angus × Nellore steers finished on feedlot. The effects of feeding regime and genetic group on shear force, thawing losses, cooking (leak + evaporation) losses, total losses and muscle fiber type, as well as carcass pH and temperature during 24 h of chilling were evaluated. There was a genetic group effec...
The effects of different ratios of sugarcane and elephant grass (0:100, 25:75, 50:50, 75:25 and 100:0% of the natural basis) were assessed on the chemical composition and losses in silages treated with a bacterial inoculant, using laboratory silos. A 2 × 5 factorial arrangement (with and without inoculant and five elephant grass ratios) in a randomized blocks design with three replications was used. Interaction...
It was evaluated the addition of calcium oxide (0; 0.5; 1.0; 1.5; and 2.0% of dry matter) effect on the chemical composition and ruminal degradability of the dry matter and neutral detergent fiber, on the losses of dry matter, and on the microbial population in sugar cane silages. A design with five levels of calcium oxide and three replications was used. All the variables were influenced by the addition of cal...
Avaliou-se a influência da forma de utilização do milho em suplementos no desempenho de novilhos na fase de terminação, durante o período das águas, em pastagem de capim-braquiária. Utilizaram-se 16 bovinos mestiços com peso inicial de 384 kg e 18 meses de idade, distribuídos em delineamento inteiramente casualizado, com quatro tratamentos mistura mineral (MM) (controle); milho triturado (MT); milho desintegrad...
O experimento foi conduzido para avaliar o valor nutritivo da silagem de capim-elefante produzida com o capim emurchecido ou adicionada de diferentes níveis de farelo de cacau. O capim-elefante foi colhido aos 50 dias de rebrota após o corte de uniformização e submetido aos seguintes tratamentos na ensilagem: capim-elefante emurchecido ao sol por 8 horas, e capim-elefante sem emurchecimento com 0, 7, 14, 21 e 2...
