MACROSCOPIC APPEARANCE OF THE FREEZED SPERM QUALITY OF KEBUMEN ONGOLE BREEDS BULLS WITHOUT THAWING MEDIA Faruq Iskandar, Riawan Yudi Purwoko dan Zulfanita
This research was conducted to determine the effect of thawing time without using media (water) on the macroscopic quality of frozen sperm. The research was conducted from March to May 2020 at the Laboratory of Integrated Animal Husbandry, Muhammadiyah University of Purworejo, Purworejo Regency, Central Java. The study used 20 strow of Kebumen Ongole Breeds Bulls which was used for insemination artificial (IA) in Kebumen Regency. The experimental design used a completely randomized design (CRD) with four treatments and five replications. Thawing duration treatments was 20, 40, 60 and 80 seconds. The research parameters were consistency, colour, odour and pH. The data obtained were analyzed by t-test and descriptive analysis. The results showed that thawing time without using media had no significant effect (P> 0.05) on the macroscopic appearance of frozen sperm quality. The 60 second thawing time without using media meets the standards for performing IA.
