【 摘 要 】

The scientific study of animal behavior, especially when the animated or inanimated environment is changed, is the main objective of ethology. Many diseases which occur in ruminants develop some degree of change in their behavior. Professionals that work with ruminants should distinguish abnormal behavior due to environmental disturbance when their welfare is negatively affected (i.e. feedlots with high stock ratio, shade deficiencies in pastures, heat stress, and errors in nutritional management) from disease conditions or nutritional deficiencies (i.e. depraved appetite caused by sodium deficiency or by lack of physically effective fiber). The purpose of this paper is to discuss the main behavioral disturbances (i.e. abnormal herd behavior, stereotypies, cross-sucking, bar-biting) verified in ruminants raised under intensive or extensive conditions in Brazil.Index
