A.S. Series 79-19
Production data on a flock straightbred Targhee ewes mated to Targhee or Suffolk rams were collected during the years of 1971 through 1975. the mean lambing percent was 93.35. The average number of lambs born per ewe exposed to rams and pere which lambed were 1.44 and 1.54, respectively. The average number of lambs weaned per ewe exposed and per ewe which lambed were 1.13 and 1.20, respectively. Crossbreeding resulted in no difference in the number of the lambs born per ewe exposed or lambing. However, Targhee ewes bred to Suffolk rams weaned approximately 1% more lambs at 90 days of age. Crossbred lambs were heavier than straightbred lambs by .97 lb. at birth, 4.7 lb. at weaning (90 days of age) 620 lb. more lamb per 100 ewes. Ewes weaning twins produced 43.8 lb. more lamb than ewews rearing a single lamb. Growth rate of male lambs appeared linear through at least 150 days of age.
