Comparative characteristic of sows of large white breed and their hybrids

Experiments on studying of reproductive qualities of pigs of breeds large white (17 heads) and hybrids large white x landras (10 goals) were scored in a country farm "Pashkov S.V." of Verkhneuslonsky district of RT. During experiment groups of sows of a different origin, age and alive weight were selected. Reproductive qualities of pigs of large white breed of the selection and genetic center "Top Hava" are higher on the majority of the studied signs of local pigs large white x landras, except a multiple pregnancy. At sows irrespective of an origin indexes of productive qualities with 1 on 2 farrow grows, and then there is their decrease to 3 and more farrows that testifies to high technological load of animals in economy.
