The average duration of first licking of perineal area, average frequency and overall average duration of licking of perineal area until ejaculation in high libido bulls were significantly (P<0.05) lower as compared to low libido bulls. Individual sperm motility (%) and viability (%) was significantly higher (P<0.05) in high than the low libido bulls. Therefore, breeding crossbred bulls can be demarcated for high libido based on based on quantification of sexual behaviour traits in relation to semen picture.
