Improving Japanese quail physiological performance under hot environmental stress in North Africa [electronic resouce].

Includes references.

The objective of the present study was to determine the effect of supplementation of Ginseng, methionine, vitamin E, folic acid and zinc on the immune function and physiological performance of Japanese quail challenged with hot environmental stress during summer season (May–June–July 2013) of Egypt (North Africa). Two hundred and sixteen birds were distributed in six treatment groups of thirty six birds which divided into three replicates, each containing twelve birds (4 males and 8 females) at 6 weeks of age. Japanese quail hens were fed the diets supplemented with 0 (nothing), 300 mg Ginseng, 0.3% Methionine , 200 mg Vitamin E, 10 mg Folic acid and 60 mg Zinc / kg experimental layer diet. All groups were put under observation for 14 weeks from 6 to 20 weeks of age. Key Words: Japanese Quail , Physiological Performance , Hot Environment.
