          Abstract

          Avaliou-se o efeito de diferentes níveis de fibra em detergente neutro (FDN), na dieta sobre o comportamento ingestivo de cordeiros Ile de France x Texel. Foram utilizados 20 cordeiros distribuídos em um delineamento experimental inteiramente casualizado, em um total de quatro tratamentos com cinco repetições, e alimentados à vontade com dietas que continham 25%, 31%, 37% e 43% de FDN. Foi utilizada uma ração em mistura completa de silagem de sorgo (AG 2005E) e mistura concentrada constituída por farelo de soja, grão de milho quebrado e mistura mineral. As dietas eram isoprotéicas contendo 17% de PB. As dietas foram fornecidas duas vezes ao dia, às 8:00 e às 16:00 horas. O comportamento ingestivo foi determinado mediante observação visual, ocorrido durante 24 horas, a intervalos de 5 minutos, para se determinar o tempo despendido em alimentação, ruminação e ócio. O aumento do teor de fibra na ração não influenciou significativamente (P>0,05) os tempos despendidos em alimentação, ruminação, ócio e tempo de mastigação total. Houve efeito linear crescente sobre as variáveis eficiência de alimentação e de ruminação de FDN (P>0,05). Os ovinos confinados possuem hábito de alimentação predominantemente diurno e de ruminação noturno.

          Translated abstract

          The effect of different neutral detergent fiber (NDF) levels in the diet on the Ile de France x Texel lambs ingestive behavior was evaluated. Twenty lambs distributed in a fully randomized experimental design were used, in a total of four treatments and five repetitions, fed ad libitum with 25%, 31%, 37% and 43% NDF diets. A ration in a complete mixing in sorghum silage (AG 2005 E) and concentrate mixing of soybean meal, fragmented corn grains and mineral mixing was used. The diets were isoproteic (17% crude protein) and were given twice a day, at 8 AM and 4 PM. The ingestive behavior was determined by observation, during 24 hours with 5 minutes intervals, to determine the time spent in feeding, rumination and idleness. The increase of the fiber level in the feed did not effect (P>0.05) on the time spent in feeding, rumination, idleness and total chewing time. The rumination and feeding efficiency increased linearly (P<0.05), as the dietary NDF levels increased. The feedlot sheeps have predominantly diurnal habit of feeding and nocturnal of rumination
