Trans-scrotal ultrasonography and breeding soundness evaluation of bulls in a herd of dairy and beef cattle with poor reproductive performance
The present study was undertaken to determine the fertility soundness of unselected bulls used for breeding based on a standard breeding soundness evaluation technique (BSE) and trans-scrotal ultrasonography (TSU). A total of 8 bulls, with the mean age of 5½ years (ranged from 3½ - 8 years) and th...

| description | The present study was undertaken to determine the fertility soundness of unselected bulls used for breeding
based on a standard breeding soundness evaluation technique (BSE) and trans-scrotal ultrasonography (TSU).
A total of 8 bulls, with the mean age of 5½ years (ranged from 3½ - 8 years) and the mean weight of 651.5kg
(ranged from 480-840 kg) were evaluated. Three bulls were Friesian Sahiwal, 2 Brangus and the rest were
Brahman-KK (Kedah Kelantan) cross, Simmental-KK cross and KK breed (one from each). Out of the total
bulls examined, 3 (37.5%) were found to be unfit to be used for breeding due to their physical unsoundness
and/or poor semen quality. The use of TSU has revealed the presence of testicular lesions in 3 bulls. The
finding of TSU (suggestive of testicular degeneration) in one bull was reflected by a poor semen quality of
the BSE results. Despite the presence of lesions of idiopathic unilateral hydrocele and bilateral fibrotic foci
lesion in the other two bulls, the BSE findings for semen quality were not compromised. In conclusion, there
was enough evidence to support our hypothesis that the observed drop in the reproductive performance of the
herd was partly the result of using bulls with poor breeding soundness for fertility.
