Abstract

Thirty-eight multiparous sows were used to ascertain whether a high (4 kg/day), compared with a low (2 kg/day) food level affected early embryonic survival. To avoid any effect on ovulation rate the treatments were imposed 3 days after mating (2 days after presumed ovulation) and continued until the sows were killed 30 days after mating. Sows which were given the high food level gained more than twice as much body weight as those on the low food level, but ovulation rates, embryo numbers, embryo body sizes and embryo survival rates were similar for both feeding levels. It is concluded that, if necessary, multiparous sows may be fed higher than normal food levels in early pregnancy without prejudice to embryonic survival.
