O trabalho teve por objetivo avaliar o comportamento ingestivo de caprinos das ra as Moxot車 e Canind谷, submetidos a dois n赤veis de alimenta o. Foram utilizados 24 cabritos inteiros (12 Moxot車 e 12 Canind谷) com idade m谷dia de quatro meses e peso vivo inicial m谷dio de 15 kg, alojados em baias individuais, distribu赤dos no delineamentointeiramente casualizado, em um arranjo fatorial 2x2 (duas ra as e dois n赤veis de alimenta o) e seis repeti es. Os n赤veis de alimenta o foram: 角 vontade (T1) e 30% de restri o em rela o ao animal que recebia alimenta o 角 vontade (T2). As observa es comportamentais foram realizadas em intervalos de cinco minutos durante 24h. Os animais das ra as Moxot車 e Canind谷 n o apresentaram diferen a significativa (P%26gt;0,05) para as vari芍veis comportamentaisobservadas. Alimenta o 角 vontade proporcionou maior atividade de alimenta o e rumina o e menor tempo em 車cio. As atividades de mic o, defeca o e procura por 芍gua foram influenciadas pela hora do dia. The aim of this study was to evaluate the intake behavior of Moxot車and Canind谷 breed goats when offered a diet at two levels of intake. Twenty-four noncastrated goats (12 Moxot車 and 12 Canind谷) were used, with an average age of four months and an initial average weight of 15 kg. The goats were housed in individual pens, distributed using a completely randomized design, in a 2x2 factorial arrangement (two breeds and two levels of intake) with six repetitions. The levels of intake offered were: ad libitum (T1) and 30% restriction (T2). The level of restriction was determined in relation to the amount consumed by animals on ad libitum intake. Behavioral observations were made at five-minute intervals during a 24hr period. There were no significant differences (p%26gt;0.05) in the observed behavioral variables between animals of the Moxot車 and Canind谷 breeds. Feeding at the level of free-choice intake resulted in greater feeding and rumination activity, and less idle time. Urination, defecation, and time spent for water consumption were influenced by the time of day.
