Resumo
The work aims to analize the behavior response and the ability to cope stressors when the piglets are exposed to aggressive treatment during the lactation phase. The behavior of 40 piglets was observed from birth to weaning (28 days). In the first fifteen days the observations were done every three days, with an interval of another three days. After this period, the observations were done once a week. Over a period of three hours, every five minutes it was registered the animal behavior. The group was divided into two treatments: rational group, where 18 piglets had minimal interaction with people and it was permitted the routine practice without sudden movements and loud sounds; and the aversive treatment, where 22 piglets received the daily routine of the farm, however, on every half hour during observations the observer performed a direct threat to the sow going into the cage with a flag and abruptly approach the animal, shouting or clapping. To avoid visual contact with the observer, he was located behind the maternity cage. Analysis of variance with fixed effects of time and time and means were compared by Tukey test or T at 5% of significance. In aversive treatment piglets spent most time at rest or exploring (P>0.05). However, in rational treatment the piglets remained resting most of the time (P 0.05). The interactions between pigs in the first phase of life areO artigo não apresenta resumo em português.
