Occurrence of flehmen in male buffaloes (Bubalus bubalis) with special reference to estrus

摘要: Pheromonal cues present in the urine and vaginal mucus during estrus period elicit courtship behaviour mammals including characteristic flehmen behaviour. In study, was assessed male buffaloes by exposing them to heifers for three consecutive estrous cycles. Behavioural observations revealed that bulls sniffed female’s external genitalia, responded chemical signal(s) exhibited similar those reported other ungulates. The recorded daily 15-min contact with females Out of 180 five days periods (� 3t oþ1 days) which included high frequency out 637 or without diestrus periods, bull displayed 365 441 behaviour, respectively. Average numbers all (2:03 � 0:66) repeated (1:05 0:64) were significantly higher than (0:69 0:25) (0:11 0:10). statistical significance (P < 0:001) as compared diestrus. case 0:01) when occurrence clearly indicates specific pheromonal compound(s) urine/vaginal influence
