title: Seasonal and sexual influences on rabbit atropinesterase.
abstract: Atropinesterase was found in 61.17% of 6686 New Zealand White rabbits of both sexes studied over 2.5 years. Significantly more males possessed the enzyme, there was a significant difference in atropinesterase frequencies in males versus females in the winter and summer seasons, and a significant decrease in the frequency of atropinesterase-positive females during the winter.
