Abstract
Study comprised 60 crossbred gilts F1 (PLW x PL), 30 fattener gilts (A) and 30
littermate primiparous gilts (B). The fattening was conducted in standard condition
from 30 to 108 kg body weight. The primiparous gilts were mated at second oestrus.
During pregnancy and lactation period they were reared in standard condition
adopted for pregnant and lactating sows. Fattener sows as well as primiparous sows
were slaughtered after end of the experiment. Market carcass value was estimated
on carcass jointing basis. It was assumed that market value is a function of
percentage share of main parts in carcass and their unitary price (PLN/kg). Market
carcass value of fattener sows and primiparous sows counted on 100 kg was
comparable.
