RESUMO

The experiment was carried through with the objective to verify the behavior of nursing nuts during 28 days lodged in different types of maternity in the period of the winter. The matrices had been distributed in a completely randomized design with three treatments and nine replications, orders of childbirth varying between 1 and 6. The treatment one understood the conventional maternity with shelter in creep and birth cage; treatment two was conventional maternity with shelter in creep and birth cage with the heating of the floor in the part of the pigs and treatment three alternative maternity, without parturition cage with shelter and access of piglets and sows during a two hours a day to outdoor in the period of the afternoon. The animals were filmed at 7, 14, 21 and 27 days for 24 hours and after weans it, the nuts had remained more in the environment, being filmed by 12 hours. Daily the maximum and minimum temperatures had been inside of the zone of praised thermal comfort for the lactation phase. It did not have a effect (P>0,10) how much to the performance of the nuts, related to the ration consumption, energy digestible, lysine digestible, corporal weight and thickness of lard. Significant differences (P>0,10) for the weight of the pig, profit of weight, weight of litter and the milk production, but they had been found(P≤0,10) for daily consumption of average ration of the litter one in gram per day, in which, the pigs kept in poles had consumed lower amount of ration when compared with the pigs lodged in the conventional maternities . The nuts kept in alternative maternities with access the poles had remained for more time in the feeder (P≤0,10) and had frequented and expended more time in the water through in relation to the matrices lodged in the conventional maternity. The matrices kept in the conventional maternities had limitation in its daily movements, due to presence of protective gratings, what it provoked greater index of stereotypes, proving in this direction, that they had remained in bigger time in other positions (P≤0,10). As much to the 21 as to the 28 days, the biggest value for energy efficiency was verified for the T1, on the other hand, the pigs of the T3 had presented greaters values of profit of weight when compared with the pigs of the T1. It appears that heating the floor of the piglets in the nursery during the winter conventional and alternative maternity paddocks with access to provide better conditions of welfare, both forsows and for piglets.
