title: Ingestive behavior and physiological parameters of goats fed diets containing peanut cake from biodiesel.
abstract: The experiment was conducted to evaluate the ingestive behavior and physiological parameters of confined goats fed peanut cake instead of soybean meal in their feed. We used 40 goats that were ¾ Boer, uncastrated, and 5 months of age on average, with an average initial weight of 15.6 ± 2.7 kg. The treatments consisted of diets with different levels of peanut cake replacing soybean meal in the concentrate (0.0, 33.33, 66.67, and 100%). The experimental design was completely randomized, with four treatments and ten repetitions. For the evaluation of feeding behavior, single animals were observed every 5 min for 24 h on 3 days. The physiological responses (respiratory rate; heart rate; rectal temperature, obtained with a rectal thermometer; and surface temperature) of the animals were evaluated at 09:00 and 15:00 h. The replacement of soybean meal with peanut cake did not change (P > 0.05) feeding behavior. The physiological parameters of the animals (P < 0.05) were altered; however, the changes appeared to be unrelated to the diet and to be due to the weather conditions. Peanut cake can replace soybean meal at 100% without causing negative effects on the feeding behavior or physiological parameters of confined ¾ Boer goats.
