Selection for reproductive rate in Rambouillet sheep. III. Correlated response in ovulation rate, lambing rate and litter size



Selection for reproductive rate in Rambouillet sheep. III. Correlated response in ovulation rate, lambing rate and litter size



Proceedings, Western Section, American Society of Animal Science and Western Branch Canadian Society of Animal Science 40: 24-26



Ewes selected for high or low reproductive rate and a randombred control line were endoscopically examined 3 to 5 days after breeding to determine ovulation rates. Fertility (ewes lambing per ewe exposed), lambing rate (lambs born per ewe exposed) and litter size (lambs born per ewe lambing) were evaluated at lambing. Ovulation rate was 1.23+or-0.03, 1.75+or-0.3 and 1.48+or-0.03 resp. in the 3 lines.
