Abstract
The comparative efficiency of male and androgenized female teaser was assessed on two herds of 67 dry and 73 lactating buffaloes. A total of 236 oestrus events were recorded during the trial, 231 oestrus events were detected combinedly by male and female teasers. Of these 231 oestrus events, 175 were correctly marked by male and 203 by female teaser. The oestrus detection rate of 74.15 vs 86.02 per cent was found for male and female buffalo teaser, respectively indicating that androgenized female teaser is more efficient and can be utilized as an aid for oestrus detection in buffaloes.
