title: Feeding behavior of finishing goats fed diets containing detoxified castor meal, co-product of the biodiesel industry.
abstract: An investigation was made into the feeding behavior of goats to evaluate the effects of a detoxified castor bean meal in the diet of goats. Thirty-six ½ crossbred Boer goats were used, with an average weight of 20 ± 3.2 kg. A completely randomized design was used with four treatments (diets with of 0, 100, 200, and 300 g detoxified castor bean meals/kg dry matter) and nine replicates. Castor bean meal was detoxified using calcium oxide. Diets were formulated to be isonitrogenous, and the forage:concentrate ratio was 50:50. The feeding behavior was observed on the 17th, 45th, and 70th days of the experiment. For the evaluation of feeding behavior (feeding, idle, and rumination times), the animals were observed in 5-min intervals for 24 h. The addition of detoxified castor bean meal did not change (P > 0.05) the evaluated behavioral variables. Linear reduction was observed (P < 0.05) in the efficiencies of feeding and rumination, expressed in g dry matter/h. The variables related to the time series discretization of the feeding behavior of goats did not change (P > 0.05) with the inclusion of detoxified castor bean meal. The inclusion of detoxified castor bean meal in growing goats' diets does not change the feeding, rumination, and idle times, however, decreases intake, feeding, and rumination efficiencies of dry matter.
