Heat Stress Induced Fetal Dwarfing and Uterine Blood Flow in Sheep

Two trials were conducted to determine if restricted feed intake would alleviate heat induced dwarfing. Birthweight adjusted for sex and litter size was reduced 1.8 kg in trial 1 (P < .05) and 1.9 kg in trials 1 and 2 combined (P < .06) with maternal heat stress. Lamb sex, litter size, lamb condition and gestation length were all correlated (P < .05). Restriction of feed to 70 percent or 85 percent of ad libitum intake during heat stress had no effect on lamb birthweight.
