Effect of Addition of Green Tea Extract (Camellia sinensis) in Egg Yolk Tris Diluter on Spermatozoa Quality in Bali Cattle (Bos sondaicus) After Freezing

This study aimed to determine the effect of adding 96% ethanol extract green tea (Camellia sinensis) in egg yolk tris diluter on quality spermatozoa Bali cattle (Bos sondaicus) after freezing. The samples were divided into four different treatment groups, which contained semen sample + 13% glycerol each (P0) 0 mg/100 ml, (P1) 0,05 ( P2) 0,10 and (P3) 0,15 ml. variables observed included motility, viability, abnormalities. Data analyzed using OneWay ANOVA continued with Duncan's test (p<0,05). results showed that P3 group had motility 49,00 ± 2,15, viability 61,92 1,70, abnormality 4,24 2,16 significantly compared other groups. In conclusion, addition ml could increase abnormal cattle.
