| Abstract |
The study was conducted to evaluated the efficacy of natural clay to reduce the effects of feeding diets polluted with lead as (lead acetate) on body weight, weight gain, feed intake, semen characteristics and some physiological responses of cocks. Forty-eight males of Gammizah strain at 32 weeks of age were divided randomly into six groups (8 cocks in each). The first group received commercial ration (control), the 2 nd group received control diet +250 ppm of lead, the 3 th group received control diet +250 ppm lead + 5% clay, the 4 th group received control diet+ 500 ppm of lead, the 5 th group received control diet + 500 ppm lead+ 5 % clay and the 6 th group received control diet + 5 % clay. After 7 weeks of treatment, cocks were kept without any treatment for another 7 weeks as recovery period.
The results indicated that supplementation of 250 and 500 ppm of lead as evidenced by a continous significant inhibitionof growth and finial body weight. Also, all semen quality traits studied were significantly (P≤0.001) decreased. Plasma total protein, albumen, globulin, total calcium, hemoglobin concentrations and serum activities of AST, ALT, and AlKp were significantly reduced. However, feed intake, sperm abnormality and dead sperm percentages were significantly increased in a dose dependent manner. Clay supplementation at 5% of diets cocks polluted lead improved (P≤ 0.01) body weight, weight gain, feed intake, semen characteristics, hemoglobin , while plasma total protein, albumen, globulin, AST, and ALT, improved (P≤0.05),
It can be concluded that the consumption of diet polluted with heavy metals such as lead caused dysfunction in the reproductive and physiological system of cockerels. While supplementation of natural clay at 5% to the diet polluted with lead can prevent the poisoning effect of lead on performance effectiveness of Gimmizah cocks.
