Abstract

Physical conformation, scrotal circumference, testicular volume, rump fat thickness, testicular echogenecity and
accessory sex glands diameter in relation to libido (poor or high) in crossbred breeding bulls (n=22) was evaluated.
Internal pelvic area (1121.60±42.19 vs 959.14±75.20 cm2) and testicular volume (454.30±21.51 cm3 vs 393.65±27.06
cm3 ) were higher (p<0.05) in high libido bulls. Rump fat thickness was lower (3.90±0.47 vs 6.03±1.17 mm) in high
libido bulls (p<0.05). The scrotal circumference, hock joint angulation, diameter of prostate and diameter of seminal
vesicles were similar in both groups (p>0.05). Thus, internal pelvic area, testicular volume and ultrasound based rump
fat thickness are associated with problem of poor libido in breeding crossbred bulls.
