Mating behaviour of rams in acceptance and late acceptance stage

摘要

This study aimed to study the sexual behaviour of ram when exposed to ewe in early and late acceptance stage of oestrus under pen mating system. Overectomized ewes were brought into oestrus artificially by using exogenous hormone. Oestrus period was divided into three stages i.e. early acceptance, late acceptance and acceptance stage based on time of oestrogen injection and reaction of ewe. Vocalization was the most predominant courtship activity.
