RESUMO:

Highest demands for good practices and animal welfare (BEA) in swine production have driven agribusiness companies to adapt their production systems. Changing from individual pregnancy stalls into group housing barns is one of the main challenges for intensive production farms. The objective of this experiment is to evaluate the reproductive parameters and Animal Welfare of swine females submitted to different group housing systems and differnt feeding models during gestation. The experiment was carried out in a sows unitfarm located in southern Brazil. A total of 1.080 females distributed in a 2 x 2 factorial scheme were used, with 10 repetitions over time. The factorial model consisted of two different transfer times to the group housing barns (immediately after the insemination protocol or at 35 days of gestation) and two different feeding process (“Y” or minibox drops). During the repetitions the females were equally distributed among the treatments in order of parturition (40 cycle 1 females; 16 cycle 5 females; 16 cycle 6 females and 36 piglets). Artificial inseminations (AI) were performed with 45 ml intrauterine doses at a concentration of 1,25 billion viable sperm. From pregnancy to delivery, reproductive parameters were evaluated: return to estrus, pregnancy checked at 28 d with ultrasound, total births and average litter weight. The analysis of Animal Welfare during pregnancy was based on the Welfare Quality® protocol, evaluating the behaviour and health of females at specific moments during gestation. Behaviour data was collected 16 different times (days 1, 8, 15, 22, 29, 36, 42, 49, 56, 63, 70, 77, 84, 91, 99 and 106 after AI). Health assessment was performed on all females on days 5, 31, 40 and 101 after AI. The final collectiondata on the field project is at the end of November 2019. The hypothesis is that the reproductive performance of swine females is better at the treatment in which females are transfered at 35 days of gestation, at stanchion feeding model.
