ABSTRACT
The fertility of goats can be seen from various parameters of sperm quality. Good sperm quality is very influential on reproductive efficiency. Vitamin E plays a role in male fertility because it can increase testicular weight, sperm count or concentration, sperm motility, and vitality. L-carnitine is an amino acid compound and is able to provide energy so that it can help improve sperm quality. The objectives of this research were to find out the sperm quality of Jawarandu goats after oral administration of vitamin E and L-carnitine. The research used 16 Jawarandu male goats, with a completely randomized design (CRD) using 4 treatments, control (P0), administration of vitamin E 50 IU (P1), administration of L-carnitine 50 mg (P2), and administration of a combination of vitamins E 50 IU and L-carnitine 50 mg (P3). The data from the research on sperm consistency and mass motility were analyzed descriptively. In contrast, the volume, individual motility, concentration, and percentage of live sperm were analyzed using analysis of variance ANOVA. The results showed that the administration of vitamin E and L-carnitine exerted a very significant effect on motility (P<0.01), the concentration, and the percentage of live sperm (P<0.05) but did not affect the sperm volume and abnormalities (P>0.05). In conclusion, the combination of vitamin E and L-carnitine gave the best results on the sperm quality of the Jawarandu Goat.
