CARCASS MARKET VALUE OF FATTENER GILTS AND PRIMIPAROUS GILTS

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.
