SEMEN QUALITY OF HORNED AND POLLED BALI BULLS TREATED WITH BEAN SPROUT (Phaseolus radiatus L.) SUPPLEMENTED FEEDING

Background. Horned and Polled Bali cattle are big meat producing livestock and have various other advantages, so they need to be maintained regarding their existence by improving semen quality. Providing bean sprouts (Phaseolus radiatus L.) in feeding is an effort to improve semen quality because of its antioxidant content that can scavenge free radicals. Objective. To determine the quality of semen from Bali Polled bull and Bali Horned bull fed with bean sprout feed supplements. Methodology. Four Horned and four Polled Bali bulls aged 5-7 years were fed bean sprouts-supplemented twice a day in the amount of 1 kg/bull for two months. Parameters observed in fresh semen include color, smell, pH, volume, concentration, and followed by motility, viability, abnormality, membrane integrity, and acrosome integrity for both fresh and frozen semen. Results. The results of the macroscopic evaluation of fresh semen showed that the color, smell, pH, and volume were not different (P>0.05) in Polled compared to Horned. Meanwhile, the microscopic evaluation showed that motility, viability, abnormality, membrane integrity, and acrosome integrity were not different (P>0.05) between Horned and Polled, but the sperm concentration of Horned was higher (P
