المستخلص: اجريت الدراسة لغرض التعرف على تاثير عملية الخصي في ذكور الماعز المحلي الاسود في مستويات الهرمونات التناسلية والصورة الدمية , وقد اشتملت الدراسة على (25) ذكرا تراوحت اعمارها بين (1.5 - 2.5) سنة وكانت خالية من الامراض والمشاكل التناسلية , وقسمت عشوائيا ال | The current study was conducted for the purpose of identification the effect of the castration in male goats on levels of reproductive hormones and some hematological parameters , and had included (25) males ranged from ages between (1.5 - 2.5) years old and was free from diseases and reproductive problems. The animals in this study were randomly divided into two groups (control group includes (10) male and experimental group includes (15) male) that housed in same conditions of nutrition and management. The levels of reproductive hormones include (Spermatogenesis Stimulating hormone (SSH) , Interstitial cell stimulating hormone (ICSH), testosterone, Estradiol - 17 beta and progesterone) as well as blood parameters that include (red blood cells( RBCs), total white blood cells ( tWBCs), packed cell volume (PCV), hemoglobin concentration (Hb), total protein and cholesterol concentration) were estimated three times before castration and in intervals of two weeks between examination and other , Experimental animals were examined after castration all hormones and blood parameters checked two weeks after castration, then after four weeks from castration, and re - measured all hormones and blood parameters after six weeks of the castration. The method of analysis Radioimmunoassay (RIA) was used to measure the levels of reproductive hormones in animals blood serums also the routine blood tests were use for checking the blood parameters. The results revealed that there are significant increased in the level of ICSH in experimental animals after castration (0.345 ± 0.0413) mIU / ml while the level of testosterone and estradiol - 17 beta significantly decrease in experimental animals after castration and the results were (0.0225 ± 0.0036) ng/ ml and (0.93 ± 0.15) pg/ ml, respectively. While castration did not show any significant effect on the levels of reproductive hormones SSH and progesterone (0.145 ± 0.01) mIU/ ml and (0.295 ± 0.03) ng /ml respectively in experimental group. The result showed that there were significant increased in RBCs , PCV, total protein and cholesterol (17125 ± 335.18) × 10 3 cell/µL , (37.7 ± 0.40) , (6.84 ± 0.25) g /100 ml and (84.41 ± 6.6) mg/100 ml respectively in experimental group after castration, while tWBCs and hemoglobin didn't affect after castration in experimental group (10788 ± 429.39) cell /µL and (11.35 ± 0.180) g/ 100 ml, respectively.
