Libido
-
Important component of BSE
-
Bulls must be observed under natural breeding conditions or special tests must be applied using restrained heifers to evaluate libido and mating.
- In 'one bull method', a bull is allowed to a restrained heifer for 10-15 minutes to mount the heifer.
- A bull should mount at least once. If he does not mount, he should fail and be tried again.
-
The 'multiple bull method' uses 4 heifers and 5 bulls on a pen perimeter.
-
Each bull should serve at least 3 times in 40 min.
-
Those bred can be removed for the others to get more chances to breed without any bull dominance affecting the breeding performance.
