| Abstract | The research and trials at the Gorin Collective Farm in the Belgorod region showed that the period of pregnancy in sows under the conditions of the industrial technology of pork production is 115 days on average with the variation from 110 to 120 days. Thus, out of 100 farrowing sows of the Large White Breed 62% had a pregnancy period of 114 to 115 days. These groups of sows had the highest multiple births (12 piglets) and the highest fertility (1.30-1.33 kg). Out of 100 farrowing Landrace sows 51% of them had a pregnancy period of 114-115 days and on average Landrace sows had a pregnancy period of 115.7 days. It should be noted that Landrace sows have the same dependence on the period of pregnancy as Large White breeds. Moreover, the deviation of the gestation period from 114 days, both in the direction of decreasing and increasing, negatively affects the productivity of both breeds of pigs. |
