Abstract

A total of 233 does were subjected to laparoscopy in order to study the relationships between litter size (LS) and its components, using linear and quadratic models. The relationships were essentially linear, but there was a quadratic relationship between ovulation rate (OR) and the number of live embryos at 12 days of gestation. OR explained a small proportion only, but prenatal survival a greater proportion of the variation in LS. Both embryo survival and foetal survival were of similar importance and appeared to operate independently.
