ACETYLCHOLINE ESTERASE ACTIVITY AFFECTING PREGNANCY IN FARM ANIMALS

Abstract

Acetylcholine esterase (AchE) activity was estimated in whole blood of 176 cows of different breed and 44 buffaloes at the time of oestrus. In general pregnancy was highest (about 60.00%) when AchE value ranged between 123 to 135 mMol/ml/hr of whole blood in COWS, whereas it was lower when AchE value was lower than about 100 mMol/ml/hr. No difference was observed due to breed characteristics. In contrast to cows, pregnancy in buffaloes was higher (63.16%) when AchE value was lower (35.50+1.72 mMol/ml/hr) whereas it decreased with increase in AchE value. This experiment shows that breed does not influence AchE value significantly but species certainly have effect on AchE activity and accordingly on pregnancy.
