Effects of adding vitamin E and selenium to basal diet on performance, sperm quality and some blood parameters in Japanese quail

This experiment was conducted to investigate the effects of adding selenium and vitamin E to the basal diet on performance, sperm quality and some blood parameters in Japanese male quails, in a completely randomized design with 240 single-day quail chicks in four treatments and five replicates and 12 birds per replicate for 42 days. The experimental groups consisted of control (basal diet without selenium and vitamin E), second treatment (basal diet plus 0.2 mg/kg selenium: S0.2), third treatment (basal diet plus 0.4 mg/kg selenium: S0.4), and fourth treatment (basal diet plus 0.4 mg / kg selenium and 150 mg/kg vitamin E: S0.4 + Vit E). Average daily gain, feed conservation ratio and feed intake had not significant difference between various treatments. The results showed significant effect of the treatments on the sperm parameters of the quail (P
