Abstract
This study was carried out to explore the effect of treated containing diets (0,5 and 10%) on some performance traits like total and daily growth rates, scrotal circumference, testicular length, testicular diameter and reproductive hormones (FSH, LH and testosterone) of Awassi male lambs. Twenty four Awassi male lambs were used (6-7 months of age and 25.5kg average body weight) they were randomly allocated into three equal groups. Ground barley grains were replace by zero, 5 and 10% of chemical and microbial treated corncobs for group 1, 2 and 3 respectively during the preliminary (2weeks) and whole experimental (90 days) period. Green roughages as well as mineral's block were available ad lib. Total and daily growth rates were calculated at the end of experiment, scrotal circumference and testicular length were measured by cloth tape whears testicular diameter was measured by vernier caliber. Blood samples were drawn from jacular vein at the end of experiment, to measure Follicles stimulated hormone(FSH), luitenizing hormone (LH) and testosterone in serum. Results indicates that supplemented treated corncobs by 5, 10% increased total and daily growth rates. Also it's effect on lambs scrotal circumference, testicular length and diameter was positively significantly (P < 0.05); whereas its effects on sex hormones (FSH, LH and testosterone) was non significant.
