EFFECT OF DIFFERENT DIETARY LEVELS OF COENZYME Q10 SUPPLEMENTATION ON THE PERFORMANCE OF SINAI COCKS FED LOW ENERGY DIET
Journal of Productivity and Development
The aim of the current study was to investigate the influence of different dietary levels of Coenzyme Q10 (CoQ10) supplementation in local Sinai cock's diet containing low metabolizable energy on the viability, hematology traits, reproductive and economic performance during the period from 40-56 weeks of age. Fifty four of Sinai cocks were weighed and divided into six treatment groups of three replicates in each and housed in individually cages The experimental diets containing two levels of
... ng two levels of energy (2940 and 2800 Kcal/Kg diet) and three levels of Coenzyme Q10 (CoQ10) ( 0, 7.5 mg CoQ10 synthetic (s) or natural (n) in 2x3 factorial arrangement. Resulted obtained indicated that body weight of cocks fed diet contained low ME +7.5 mg CoQ10s / kg diet was significantly (P≤0.05) decreased as compared to those fed diets containing low ME without CoQ10 and the diet with high ME + 7.5 mg CoQ10s. Hatchability of fertile eggs % was significantly (P≤0.05) high due to feeding on diet supplemented with 7.5 mg CoQ10s in comparison with those fed diet supplemented with CoQ10n or free CoQ10. Fertility percentage was improved as a result of dietary supplementation of CoQ10s to the diet which contains 2800 Kcal/kg diet. Also, there was an insignificant increase in hatchability of set eggs% due to addition 7.5 mg CoQ10s / kg diet. The progressive motility % of sperm and blood serum triglyceride were significantly (P≤0.05) improved by decreasing ME content in the cock's diet. Interaction between ME and CoQ10 had significantly effect (P≤0.05) on final BW where, final BW of cocks fed diet contained low ME (2800 Kcal) +7.5 mg synthetic CoQ10 (CoQ10s)/ kg diet was significantly (P≤0.05) decreased as compared to those fed diets contained low ME without CoQ10 and the diet with high ME + 7.5 mg CoQ10s. 624 BESHARA et al. However, the interaction between low level of ME and 7.5 mg CoQ10s caused to improve significantly (P≤0.05) RBC, HEB, H, and H/L as compared to the other dietary interaction treatments. However, all dietary interactions treatment groups were recorded significantly (P≤0.05) the lowest value of serum cholesterol when compared to the diet contained high ME without CoQ10. The ratio of HDL/LDL was significantly (P≤0.05) increased by feeding on diet contained high ME supplemented with CoQ10n and the diet contained low ME without CoQ10 as compared to the other interaction treatments. The results illustrated that the beneficial influence of CoQ10 supplementation in diet contained low level of ME to improve the histological studies of Sinai cocks testes. Conclusively, it could be concluded that there were a beneficial affects due to adding 7.5 mg CoQ10s /Kg diet contained low ME level, and therefore it could be used a functional feed additive in diets of Sinai cocks to maximize the reproductive and economical performance during the period from 40 to 56 weeks of age.
