“…This fact contradicts the expectations because the intake of these components was reduced by the addition of RFO (Table 2). Conversely, Freitas et al (2010) and Agy et al (2012) found that feeding efficiency is influenced by the intake of component nutrition (DM and NDF). However, the effect of RFO levels on feeding efficiency has not been verified by regression analysis.…”

“…These differences may affect intake behavior, which is influenced by the physical structure and the chemical composition of diets (CARVALHO et al, 2004). The study of intake behavior is necessary to evaluate foods and diets, to elucidate problems related to decreased consumption, and to adjust the feeding regime of the animals to maximize production and economic performance (AGY et al, 2012). Intake behavior has been studied with regard to the characteristics of food, rumen motility, alertness and the climatic environment.…”

The objective of this study was to evaluate the ingestive behavior of lambs fed diets containing different levels of residual frying oil. Different residual frying oil concentrations (0, 20, 40, 60 and 80 g kg -1 dry matter base) in the diets of lambs were evaluated. The experimental diets were formulated to contain 12.8% crude protein (CP) with a 60:40 roughage:concentrate ratio. In each observation period, the following variables were measured: time spent eating, time spent ruminating, time spent idle, and number and time of ruminating chews per ruminated bolus. Animals were randomly allocated to treatment groups according to a Latin square design, with five treatments and five experimental periods.The average values were analyzed using regression analysis to 5%. There was no difference for the time spent feeding, ruminating and being idle. No differences in daily feeding number, total chewing time, number of rumination boluses, number of rumination chews per bolus, rumination chew time per bolus and feeding efficiency were observed. The efficiency of rumination for dry matter and neutral detergent fiber showed a decreased linear effect. It can be concluded that the inclusion of residual frying oil does not affect activities of feeding, rumination and being idle as well as the parameters of rumination chewing, but it does decrease the efficiency of rumination. ResumoObjetivou-se avaliar o comportamento ingestivo de carneiros alimentados com dietas contendo teores de óleo residual de frituras. Foram avaliados os teores 0, 20, 40, 60 e 80 (g kg -1 base MS) de inclusão de óleo residual de frituras em dietas para carneiros. As dietas foram formuladas para conterem 12,8% de PB mantendo uma relação volumoso:concentrado de 60:40. Foram usados cinco carneiros com peso inicial de 36,8 ± 3,3 kg. O comportamento ingestivo foi avaliado no 11º dia de cada período experimental, através da medição do tempo gasto em alimentação, ruminação e descanso por meio de observações visuais realizadas a cada 5 minutos, durante 24 horas. No mesmo dia, foi realizada a contagem do número de mastigações merícicas e do tempo despendido para ruminação de cada bolo, com a utilização de um cronômetro digital. O delineamento experimental utilizado foi quadrado latino (5 x 5). Os valores médios foram analisados por meio de análise de regressão à 5%. Não houve efeito da adição do óleo residual de frituras sobre o tempo de alimentação, ruminação e ócio, nas variáveis relativas a mastigação merícica e eficiência de alimentação. Houve efeito linear decrescente para a eficiência de ruminação da MS e do FDN. Conclui-se que a inclusão de óleo residual de frituras não afetou as atividades de ingestão, ruminação e ócio, bem como, os parâmetros da mastigação merícica, mas reduz a eficiência de ruminação. Palavras-chave: Lipídeo. Alimentação. Ruminação. Ócio. Mastigação Merícica.

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.
