- Abstract
The present work was carried out at the Poultry Research Station, El-Azab, Fayoum belonging to Animal Production Research Institute, Agricultural Research Center, Ministry of Agriculture, during the summer season (July to September) the to study the effect of supplemented Selenomethionine (Sel-Plex); Zinc Glycine (Zn-Gly) to the diet and their interaction on productive, physiological performance, testosterone hormone, and some semen quality in natural environments during Egyptian summer months from July to September. A total number of 162 Golden Montazah (GM) cocks from 29 to 40 weeks of age were randomly divided into 9 equal treatments (T) with3 replicates each of 6 cocks. The first treatment was fed the basal diet and served as control, while treatments 2, 3, 4, 5, 6, 7, 8 and 9 were given the basal diet supplemented with 0.2 mg Selenomethionine (Sel- Plex); 0.3 mg (Sel-Plex); 100 mg Zinc Glycine (Zn-Gly); 125 mg (Zn-Gly); 0.2 mg (Sel- Plex) + 100 mg (Zn- Gly); 0.2 mg (Sel-Plex) + 125 mg (Zn-Gly); 0.3 mg(Sel-Plex) + 100 mg (Zn-Gly) and 0.3 (Sel-Plex)+ 125 mg/ kg diets, respectively. Results revealed that adding Sel-Plex with Zn-Gly or either alone to the diet (T9, T8, T7, T5 and T3), respectively, of GM cocks results in significant (P<0.05) increase in live body weights (LBW), change BW, aspartate-aminotransferase (AST), alanine aminotransferase (ALT), ejaculate volume, alive sperm (%) and sperm concentration. Testosterone hormone values was significantly increased (P≤0.05) by cockerels fed on T9, T8, T7, T6 and T4, respectively, compared to T1 (control). Therefore, adding Sel-Plex, Zn-Gly and the effect of Se combined with Zn to the diet could be used as an efficient tool for maintaining high potency of GM males under hot climate condition.
