Abstract EN

The aim of this study was to investigate the effect of using milled Zingiber Rhizome and vitamin E on some reproductivity traits (serum hormones levels, SSH and testosterone and semen characters).

Eighteen Iraqi Black kids at age of 5-6 months were bought and divided into three groups equally (body weight was considered), each group contained 6 kids.

This study was carried out in Animal's Farm, College of Veterinary Medicine, University of Baghdad from 1st November 2007 up to end of May 2008, and treated as followed: The first group (Z) (Zingiber group) was fed on concentrates diet (400 g/head) daily which contained 10 g of zingiber (2.5% of diet).

The second group (Z+E) (Zingiber group + vit.

E) was given the same concentrate diet mentioned above (400 g/head) daily and administered of vit.

E with a dose of 400 mg/head orally given bimonthly for each animal.

Animals of the third group were fed on a concentrate diet (400 g/head) daily which was free of Zingiber kept as a control group.

The results revealed the followings: With experimental period progress, SSH hormone level of all groups were increased, while no significant differences among different groups were obtained in spite of mathematically increased in group 1 and 2 compared with the control group.

Testosterone hormone level was progressively increased in all groups, the first and second groups showed significantly (P<0.05) increased compared with the control group at end of the experimental period.

The kids in the second and first groups showed their pubertal stage at earlier age than the control group.

While the second group showed more earlier than the first group.

Most semen quality characters recorded mathematically or significantly (P<0.05) better in the group 1 and 2 compared with the control group.

While the animals in the 2nd group gave better values in most semen characters compared with those in the first group.

It is concluded that by using Zingiber rhizomes caused an improvement of some reproductivity and physiologically traits of male goat kids by administration of Vit.

E caused more improving
