EFFECT OF REDUCING SUNFLOWER CAKE AND SEEDS DEGRADABILITY ON PUBERTY AND TESTICULAR MEASUREMENTS Of AWASSI LAMBS

This study was conducted to elucidate the effect of lowering sunflower cake degradability or seeds on puberty, testicular and blood measurements Awassi lambs. Thirty lambs with an average body weight 25.93 ± 0.42 kg 3- 4 months old. Lambs were divided into three groups (10 in each group) first group fed a diet contained 11% (T1), second low degradable (T2), while third that (T3). The results indicated reduce (T3) led significant increase (p≤ 0.05) length right left testes (8.35 8.30 cm) respectively as compared T1 (7.84 7.77 T2 (7.88 7.63 respectively, scrotum volume increased significantly T3 165.72 cm3 151.86 cm3, Testosterone hormone concentration 0.01) 2.81 ng/ml ( 1.455 1.75 ng/ml) . Also, feeding (T2) enhance seminiferous tubule diameter, germinal epithelium height, Sertoli cells count (T1). indicate reducing protein fat sources rich unsaturated fatty acids diets before puberty had positive role development testosterone secretion at puberty.
