Kualitas semen segar dan recovery rate sapi bali pada musim yang berbeda

Abstract: This research was conducted at the Center  of Artificial Insemination (BBIB) Singosari , Malang, East Java. The purpose of this research was to determinethe parameters of fresh semen quality including volume, pH, individual motilityand concentration of frozen semen production and  recovery rate of  Bali bulls in different seasons. The material used were fresh semen of 14 heads of Bali’sbull in 3, 5, 6, 10, and 11 years and secondary data from November 2015 toSeptember 2016 at BBIB Singosari. The method used in this research was case study and the data were analyzed descriptively. The results showed that the highest volume semen Bali bull in summer was 6.05±1.50 ml. The pH in rainy season and summer were 6.5±0.07. Semen of Bali’s bull dominated by the white-milk color. The highest of color (white-milk), individual motility, concentrationand total of frozen semen production were at summer in September. The average of color, individual  motility, concentration  and total of fozen semen production were 89%±0.10, 66.98 ± 0.05%, 1159.25 ± 211.28 million/ml and 22682 ± 707.95 straw. Post thawing Motility (PTM) and RR value were 45.28 ± 0.02%; 66.79± 0.05 semen of Bali’s bull highest at summer in August. The conclusion  showed thedifferences of season will affect to volume, color, individual motility, concentration, PTM, the value of RR and production of frozen semen Bali bull, but it is not effect for pH semen.
