Abstract
A total number of twelve healthy Damascus goats' bucks aged 1.7-2.3 years and weighed 56.7±1.34 kg were used to study the effects of treatment with L-carnitine, Co-enzyme Q10 and Zinc-methionine on semen quality and some blood parameters in Damascus goat bucks. The bucks were assigned to four groups (3 bucks in each group). The first group( control) was fed basal ration composed of 60% concentrate feed mixture (CFM) plus 20% clover hay and 20% rice straw. The 2nd group was fed basal ration and injected with 50 mg L-carnitine/Kg live body weight twice weekly. The 3rd group was fed basal ration and injected with 6 mg Coenzyme Q10/kg live body weight twice weekly. The 4th group was fed basal ration and orally administered daily 25 mg Zinc-methionine. Physical semen characteristics, physiological response parameters and blood biochemical parameters were studied. The obtained results showed that treatment with L-carnitine, Coenzyme Q10 and Zinc-methionine significantly (P<0.01) improved semen quality of Damascus goat bucks. Bucks injected with 50 mg L-carnitine/Kg live body weight recorded the best values of physical semen characteristics as compared to goats injected with 6 mg Coenzyme Q10/ kg live body weight or those administered 25 mg Zinc-methionine. Hair, skin and rectal temperatures were significantly (P< 0.0%) decreased in goat bucks treated with L-carnitine, Coenzyme Q10 and Zinc-methionine than the control group. Values of pulse rate (beat/min) and respiration rate (beat/min) were not significantly affected by treatment with L-carnitine, Coenzyme Q10 and Zinc-methionine. Treatment with L-carnitine, Coenzyme Q10 and Zinc-methionine were not significantly affected on most of all blood biochemical parameters with the exception of AST, Testosterone and cortisol levels were significantly (P<0.05 or P < 0.01) affected in the treated groups compared to the control group. Goat bucks injected with 50 mg L-carnitine recorded the lowest values of AST and the highest values of testosterone as compared to the other groups. However, goat bucks injected with Coenzyme Q10 6 mg/ kg live body weight recorded the highest value of cortisol as compared with the other groups. In conclusion, injection of Damascus goat bucks with L-carnitine at level of 50 mg/Kg body weight or CoQ10 at level of 6 mg/Kg body weight or orally administration of zinc methionine at level of 25 mg/head /day improve their semen quality, maintain their health status and protect them from heat stress during hot summer season of Egypt.
