Effect L-Argnine Acid Injection on Sex Cells in Shami Goats
Keywords:Sex Cells – L-Argnine Acid - Shami Goat.
This study was conducted with the aim of showing the effect of injecting L-Argnine acid on characteristics of spermatogonia, for Period
15/7/2021 until 15/10/2021 in the animal farm/ Ruminant hall of Animal Production Department /College of Agriculture / University of Diyala. This study include 12 male of Shami goat aged (1.5-2) years, with an average weight (37-40) kg, were divided randomly to four equal groups (3/ male / group): the first was a control group (without injection) (T1), while the second (T2), third (T3) and fourth (T4) groups were injected intramuscular with L-Argnine Acid in concentration 125, 250 and 375 mg /48 hour. The animals were slaughtered after the end of the experiment. The number of spermatogonia cells, Sertoli cells and the number of Leydig cells, germ cell layer, seminiferous tubule diameter and Seminiferous lumen of the tubule were measured. The results showed that the injection of L-Argnine Acid led to highly significant increase (p<0.01) in the number of Sertoli cells, Leydig cells, inside the seminiferous tubule, as T4 and T3 were superior on T1and T2,, T2 were superior on T1. There was also highly significant effect (p<0.01) for injection in the number of Leydig cells, spermatogonia cells. So T3 and T4 were superior on T1and T2, and T2 was superior on T1. The number of Spermatogonia cells also outperformed the T3 and T4 transaction on T1 and T2 transaction, T2 were superior onT1 and there were no significant differences between T3 and T4. The results showed that the was a significant effect (P<0.05) for Aspartic acid injection in the thickness of germ layer, as T4 was superior on rest treatments, while T3 was superior on T1and T2. There was also highly significant effect (p<0.01) for injection in the seminiferous tubule diameter, asT4and T3 was superior on T1 and T2and T2 was superior on T1.in the thickness of the seminiferous tubule lumen, T4 was superior on T2and T1, no significant differences were observed between the T1 and T2 with the T3, no between the T3 and T4.
