Comportamento ingestivo de ovinos Santa Inês alimentados com dietas contendo farelo de cacau

Abstract: O experimento foi conduzido para avaliar o comportamento ingestivo de ovinos alimentados com dietas contendo farelo de cacau. Foram utilizados 16 ovinos Santa Inês fêmeas, não-gestantes e não-lactantes, com peso corporal médio de 25 kg e aproximadamente 12 meses de idade, mantidos em baias individuais. O farelo de cacau foi fornecido no concentrado nos níveis de 0, 10, 20 e 30% e, como volumoso, utilizou-se feno de mandioca. As dietas foram fornecidas em mistura completa, na proporção 50:50 volumoso:concentrad… Show more

“…Nunes et al (2010), however, evaluated the supplementation of lambs with sisal (Agave sisalana) fodder salt and did not observe alterations in the feeding behavior of the animals, which was probably due to the low quality of sisal, which showed a CP content of 524 g/kg −1 in its chemical composition compared with the Gliricidia hay, whose average CP content was 211 g/kg −1 . A similar response was reported by Carvalho et al (2006), who evaluated the feeding behavior of feedlot Santa Inês sheep and observed that as the animals reduced the number of cuds ruminated per day, they increased the number of rumination chews per cud. Evaluating the feed and rumination efficiencies (g DM and NDF h −1 ), we observed that these variables were highest for the animals supplemented with GFS (Table 7).…”

“…The material consisted of tender branches with leaves from the arboreal stratum, at around 120 days of age, in the vegetative stage, which were previously dried in the sun for two days, and turned every 4 h until it reached hay point, with 150 g/kg −1 moisture (CAVALCANTE et al, 2004). After haying, the material was ground through a sieve with 0.8 mm screen aiming to facilitate the uniformity with the mineral salt and prevent selectivity by the animals.…”

“…Alterações nos tempos despendidos nas atividades de alimentação, ruminação e ócio têm sido, frequentemente, observadas em trabalhos nos quais as dietas experimentais apresentaram variações nos teores de fibra (MACEDO et al, 2007;MENDES et al, 2010). Estes resultados corroboram com os obtidos por Carvalho et al (2008), que, ao avaliarem o comportamento ingestivo de ovinos alimentados com dietas contendo 50% de concentrado e diferentes porcentagens de farelo de cacau (0, 10, 20 e 30%) em substituição parcial ao concentrado à base de milho moído e farelo de soja, não verificaram diferenças nas atividades de alimentação, ruminação e ócio.…”

“…6). Carvalho et al (2008) comentam que o consumo diário de alimentos pode ser descrito pelo número de refeições consumidas por dia, pela duração e pela taxa de alimentação, a qual é representada pela velocidade em que cada refeição é feita. Segundo Silva et al (2005), o padrão de procura de alimentos por bovinos confinados é bem característico, com dois momentos principais: início da manhã e final da tarde.…”
