Abstract:

The researches were carried out with the goal to quantify the influence of differential housing and feeding of the pregnant sows until 28 and respectively 56 days of gestation, upon prolificacy and farrowing loss (stillborn). The prolificacy of the sows housed in crates and feed individually, according to the body condition, until 56 days of pregnancy was 10.98±1.58 pigs/sow; with limits from 9 to 13 pigs born alive/sow. For the sows housed in crates and feed individually, according to body condition, until 28 days of pregnancy, prolificacy was 10.92±3.59 pigs/sow; with limits from 4 to 14 pigs born alive/sow. Most of the sows (60.42% of the sows housed inc rates until 56 days and 53.33% of the sows housed in crates until 28 days) farrowed 11 pigs born alive/sow. Regarding the farrowing loss, for the sows housed in crates until 56 days, the number of stillborn was 0.31 pigs/sow; for the sows housed in crates until 28 days, the number of stillborns was 1.14 pigs/sow.
