The beef cattle industry is developed in all states and in different climates of Brazil. Cattle despite the group life bring a series of adaptive advantages, and also results in competition for resources that are exposed, showing some aggressive changes between them. The aim of this study was to evaluate the behavioral activities and social interactions of bulls in the Angus breed migrants from another state with animals born and raised in a producing property in beef cattle located in Coronel Domingos Soares - PR, where the study was conducted. Nine bulls with age and initial weight of 28 months and 482.66 kg were used. Three bulls from another region were distributed in a pasture, with predominant forage species such as Hemártria and grass Jesuita Missionera. The animals received daily supplementation with corn silage and corn cob. The Bulls received on average 7.30 kg of corn silage and 5.30 kg of corn cob per animal daily, this represents 1.5% of body weight of corn silage and 1.09 % of body weight cob maize. And estimates of the chewed reviews of behavioral activities ( standing idle , OD : lying idle , RE : standing ruminating , RD : ruminating lie ; B drinking water in AC Feeding trough OE grazing PA ) were made and rumination. The animals were most of their time feeding. The treatment of the animals had mixed media PR 152.22 minutes / day during the grazing time. The rumination activity standing, had a coefficient of variation of 77.72 %. The animals in the first week of the experiment were not suited to each other, from the second week environment has been possible to observe the adaptation by the amount of times that the animals were feeding in the trough and graze and also by the time they would lie that is a sign of adaptation. The best method of introduction that was found was to put the animals together with others, since they grazed over, and showed good adaptation in animals in group. |
