The results showed that, semen quality is significantly depended on individual. Bull number 05 had the best semen quality, expressed as it had better semen volume, higher sperms activity, sperm livability, and higher sperm mobility (3.18 ml, 70.89%, 94.78%, 2.2 billion/movement) and had the lowest abnormal sperm morphology (6.63%). The quality of semen is autumn showed the best with V, A, C, Sg and VAC parameters were (3.21 ml, 70.96%, 1.08 billion /movement, 94.82% and 2.47 billion / ejaculate. The solution 2 (MT2) with 7.5% glycerin showed to have higher post defrost  semen quality with the sperm activity (A) was 39.93%, Abnormal sperm morphology (K) was 9.92% and sperm mobility was 85.27%.
