Comportamento de vacas leiteiras em sistema silvipastoril e em pleno sol em uma pequena propriedade leiteira do sudoeste do Paraná

Abstract

The study aimed to evaluate the behavior of dairy cows in silvopastoral system and time spent in each activity by grazing, rumination, other, milk production, in addition to room temperature. We used two treatments sun and shade, the animals were distributed in a completely randomized design with five cows per treatment. The behavior of the cows was observed every ten minutes. It was found that the animals grazed the sun unless the animals had access to shade, because when the temperature increases they decrease their activities to maintain body temperature and thus reduce the intake of pasture. For the rumination of the sun as the animals had no access to shade, chewing remained longer, to reduce the stress they were suffering. For leisure activities there are differences between the treatments since shadow animals remained for a longer time without performing activities, since they did not suffer from stress.
