The Effect of Using Different Levels of Red Ginseng Roots Powder on some Physiological Characteristics of Japanese Quail Males (Coturnix japonica)

The current study was conducted to investigate the effect of adding different levels of ginseng roots to the diet on some physiological characteristics of Japanese quail males. A total of 120 Japanese quail males aged one week were used in this study. The males were randomly distributed into four experimental treatments (n=30). Each treatment was replicated three times (10 individual each). Males were fed experimental diets that were formulated to contain the same components as the control diet which contained red ginseng roots powder at levels 250, 500 and 750 mg/ kg feed  in other three experimental diets respectively. The results showed that the males of the fourth treatment recorded the lowest mean of the age of sexual puberty. While the highest average of sexual puberty age was recorded by the males of first treatment. On the other hand, the fourth treatment recorded the highest relative weight of testes compared with the other treatments at the age of 30 and 60 days. The results indicated that the males of the fourth treatment recorded highest Testosterone, FSH and LH levels compared with the other treatments at the age of 60 days. We can conclude from this study that the highest concentration of powder ginseng roots (750mg/kg feed) can promote the development of testes and increase testosterone, FSH and LH hormones in the serum of Japanese quail males.
