The result of artificial insemination in pigs. The length of gestation period in sows and gilts of the Norwegian Land Race inseminated with semen from ten different boars

, : The result of artificial insemination in pigs. The length of gestation period in sows and gilts of the Norwegian Land Race inseminated with semen from ten different boars. Acta Agric. scand, 9: 189

Data on gestation length are summarised. The av. gestation period in 914 Norwegian Landrace sows was 114.17+or-0.06 days with a standard deviation of 1.82. There was a significant difference in gestation length between the 10 boars used. It was found that there was a tendency for sows with large litters (10 or more) to have shorter gestations than those with smaller litters.
