Pigs slaughtered at 156 kg BW ate more feed and had
worse feed conversion than pigs slaughtered at 145 BW. An increase in SW improved carcass yield, but
tended to decrease trimmed ham yield. Intact females are an alternative to castrated females for intensive
production of Iberian pigs. Also, the reduction in slaughter weight from 156 to 145 kg BW is recommended
for this type of production.
