The effect of Moringa oleifera leaves on the quality of Bali bulls semen

This study aimed to investigate the effects of Moringa oleifera leaf (MOL) as a feed supplement on the semen quality of Bali bulls. The study was divided into two periods of 8 weeks (before and after) the supplementation of MOL. Four Bali bulls, weighing 250-350 kg, aged 3 to 4 years old were used in this study. At the second period (treatment period), the bulls were supplemented with dried MOL 0.1% of body weight. Semen was collected from the bulls once a week using an artificial vagina. The parameters in this study were macroscopic and microscopic evaluation of semen. Macroscopically evaluation of semen consisted of volume, pH, color, and viscosity. Microscopically evaluation of semen included mass movement, total sperms motility, and semen concentration. Microscopic evaluation of semen was conducted using Computer- Assisted Sperm Analysis (CASA). Furthermore, the data obtained were analyzed using SPSS with a Paired T-Test Sample design model. The results of this study showed that the quality of Bali bulls semen that supplemented with MOL had significantly (P<0.01) higher than the control group, both macroscopic and microscopic evaluation. Supplementation of MOL enhanced volume, color, viscosity, mass movement, sperm motility, sperm concentration of Bali bulls’ semen. In a conclusion, supplementation of MOL in the feeding of Bali bulls improved the semen quality.
