Abstract: Ingestive behavior of sheep fed diets containing four levels of castor mealThe aim of this work was to evaluate the effect of the replacement of four levels of a soybean meal by detoxified castor meal in rations fed to seven month-old ½ Morada Nova x ½ WDB (without defined breed) crossbred lambs, average 18 kg BW, on their ingestive behavior. The experiment was conducted in a completely randomized design with four treatments and five replicates. Continuous (feeding time, rumination, other activities and idlene… Show more

“…The values obtained in this study for rumination efficiency in g DM/h corroborates those verified by Vieira et al (2011), who found no significant difference for this parameter when soybean meal was substituted by DCBM at the levels of 0; 50; 75 and 100% with respective means of 198. 06; 202.75; 197.14 and 224.19 g DM/hour.…”

“…The values obtained in this study for DM intake corroborate those verified by Vieira et al (2011), who found no significant difference for this parameter when substituting soybean meal by detoxified castor bean meal at the levels of 0; 50; 75 and 100% with respective means of 1550; 1490; 1530 and 1490 g/animal/day, confirming that the use of this co-product in the feeding of sheep does not limit DM intake.…”

“…Regarding the time spent in rumination, the intervals between 11 and 15 h were the first It was possible to observe that in all treatments the rumination process started one to two hours after feed intake. According to Vieira et al (2011) the rumination peaks between 01h and 07h are due to the rest of the animals, where the activities alternate between the processing of the ingested food and idleness (Figure 2). concentrates, because the greater proportion of hay promotes the faster filling of the rumen, leading the animals to idle state .…”

“…Isso pode ser explicado pela ausência de variação significativa no consumo de MS e de FDN, e pela condição isonutricional das dietas testadas. Resultados semelhantes foram observados por Vieira et al (2011) que ao trabalharem com borregos Morada Nova alimentados com dietas contendo 0; 50; 75 ou 100% de farelo de mamona autoclavado em substituição ao farelo de soja não verificaram diferenças quanto ao consumo de MS, tempos de alimentação e de ruminação, eficiências de alimentação e de ruminação, tempo de mastigação total, número de bolos ruminais, tempo de mastigação merícica por bolo ruminal e número de mastigações merícicas por bolo. O tempo de alimentação dos animais recebendo a dieta NT foi semelhante ao dos animais recebendo as rações com torta de mamona tratada, não se confirmando Como a composição química das dietas foi próxima, assemelhando-se, assim, na densidade nutricional, os animais atingiram suas exigências nutricionais em tempos similares, não ocorrendo diferenças no tempo em ócio.…”
