Comportamento de suinos submetidos a diferentes sistemas de pastejo em pastagem de trevo-branco


This work aimed to study the behaviour of pigs submitted to different grazing systems (continuous, alternated or rotational) in white-clover (Trifolium repens L.) pasture and fed ad libitum. 36 finishing pigs, castrated males, averaging 80 kg were used. The behaviour activities (feeding, grazing, drinking, standing, laying, sitting, walking, urinating, defecating, playing, itching, rooting, and digging) were recorded by visual observations during three consecutive days, from 7:00 a.m. to 6:00 p.m. The experiment was analysed as a complete randomized blocks, with three treatments and three replicates. The observations were made every 10 minutes and the number of animals and the respective activities on each grazing system were recorded. Lying, drinking, feed intake, grazing and walking were the activities that showed higher frequencies, regardless of the grazing system. Pigs on alternated grazing system showed higher frequency feed intake activity than pigs on continuous or rotational grazing systems. During the first day of observation, pigs on continuous or rotational grazing systems showed higher frequency grazing activity than pigs on alternated system. The pigs on continuous and rotational grazing systems showed similar behaviour activities. The behaviour of growing pigs was affected by the grazing system.
