Resumo: | The objective of this experiment was to study the intervals of time for observing the ingestive behavior of 36 young crossbred bulls in feedlot. The animals were housed in individual stalls, in a completely randomized design, with three treatments (sorghum silage with 1.0 % concentrate, sugar cane with 1.0 % concentrate and sugar cane with 1.2 % concentrate). Five different intervals between observations were studied. The evaluated parameters were: feeding, rumination and idle, time and frequency, dry matter and neutral detergent fiber intake, total chewing time, feeding and rumination efficiency of dry matter and neutral detergent fiber, as well as, the percentage of the time in that the animals were laying during rumination or idle. The intervals of time did not differ (P > 0.05) for analyzed variable of the time and efficiency. The percentage of time in that the animals were laid while ruminating, was 91 %. The frequencies of feeding, rumination and idle, differed (P < 0.05) among all intervals. It can be concluded that the evaluation of ingestive behavior can be carried out at 30 minute intervals when did not study the frequency. |

Foram utilizados 36 animais, alojados em baias individuais, em delineamento inteiramente casualizado, com três tratamentos (silagem de sorgo com 1,0 % de concentrado, cana-deaçúcar com 1,0 % de concentrado e com 1,2 % de concentrado). Foram comparadas cinco escalas de intervalos de observações. Avaliou-se o tempo e freqüência de alimentação, ruminação e ócio, sendo que destes dois últimos itens calculou-se a percentagem do tempo que os animais permaneciam deitados, ingestão de matéria seca e de fibra em detergente neutro, tempo de mastigação total e eficiência de alimentação e de ruminação da matéria seca e da fibra em detergente neutro. Não se observou diferença significativa (p > 0,05) entre as escalas de tempo analisadas para as variáveis relacionadas a tempo e eficiência. A percentagem de tempo que os animais permaneceram ruminando deitado ficou em torno de 91%. As freqüências de ingestão, ruminação e ócio diferiram (p < 0,05) para todas as escalas de tempo avaliadas. Concluiu-se que o estudo do comportamento ingestivo de ruminantes pode ser efetuado com escalas de até 30 minutos de intervalo quando não se avalia a freqüência.UEL2008-08-30info:eu-repo/semantics/articleinfo:eu-repo/semantics/publishedVersionapplication/pdfhttps://ojs.uel.br/revistas/uel/index.php/semagrarias/article/view/272810.5433/1679-0359.2008v29n4p955Semina: Ciências Agrárias; Vol. 29 No. 4 (2008); 955-960Semina: Ciências Agrárias; v. 29 n. 4 (2008); 955-9601679-03591676-546Xreponame:Semina.
