Effect Of Sprouts (Phaseolus Aureus) Addition In Ration On The Quality Of Friesian Bull Semen

A research on effect of bean sprouts (Phaseolus aureus) addition in ration of Friesian bull has been conducted in term to learn its effect towards motility and abnormality of their sperm. This research was conducted at Artificial Insemination Center in Lembang District, West Java, using 16 head of Friesian bulls of 3 – 3.5 years old and 800 – 900 kg of body weight. Treatment of ration were T0: basal ration without bean sprout ; T0.5 : T0 + 0.5% bean sprout; T1.0 : T0 + 1.0% bean sprout; T1.5 : T0 + 1.5% bean sprout. Feeding treatment was applied in two months and semen collection was conducted weekly for four times started from the end of feeding treatment. The study uses Completely Random Design. Each treatment was replicated 4 times. Data of this research was analyzed by ANOVA. Conclusion of the research is that addition of 0.5% bean sprout on bull ration is the optimum proportion to improve sperm motility and decrease sperm abnormality; however, addition of bean sprout has no effect on the other variables of Friesian bull semen qualities – either macroscopically or microscopically. And so, on the post thaw semen qualities that measured via post thaw motility and conception rate. Key words: Friesian Bull, Bean sprout, sperm qualit
