【 摘 要 】

Artificial Insemination is a compatible method of reproduction in an effort to increase dairy productivity. Artificial Insemination Center as a producer of frozen semen was required to maximize bulls in producing high quality frozen semen optimally. The purpose of this research was to determine effect of age and bulls on fresh semen quality and frozen semen production of Holstein bulls in Indonesia. The research was conducted at Lembang and Singosari AI Centers. The material used were 24.634 data of qualified fresh semen and frozen semen production from 81 Holstein Bulls aged 1-9 years that used as frozen semen producer in period of 2008 to 2016. The variables observed in this research were data of age of bulls, fresh semen volume (mL); sperm motility (%); mass movement; concentrations (million/mL) and frozen semen doses at each production at age of bulls. Nested design was applied to obtain and analyze data. Results showed that Age and bulls have significant effect (P
