ABSTRACT
Artificial insemination is one of the reproductive biotechnology methods used to improve the genetic quality of livestock. Some factors affect the success of artificial insemination, including the quality of the frozen semen. This research examined the effects of carrot extract addition in egg yolk diluent tris aminomethane on the quality of frozen semen of Boer goats. Fresh semen was collected from 5 male Boer goats aged 5–7 years, with minimum mass sperm motility of ++ and individual motility of at least 70%. The semen was diluted using tris aminomethane egg yolk added with different concentrations of carrot extract. In this experimental research, 4 treatments with 5 replications and a laboratory experiment using a completely randomized design (CRD) were carried out. The treatments in this study were P0:0% carrot extract + 80% tris aminomethane + 20% egg yolk, P1:1% carrot extract + 80% tris aminomethane + 20% egg yolk, P2: 2% carrot extract + 80% tris aminomethane + 20% egg yolk, P3: 3% carrot extract + 80% tris aminomethane + 20% egg yolk. The addition of carrot extract in egg yolk tris aminomethane had a significant effect (P<0.05) on sperm individual motility and viability. To sum up, the addition of 1% carrot extract had better results than other treatments.
