Effect L-Argnine Amino Acid Injection on Some Characteristics of Semen in Shami Goats

Abstract

This study was conducted with the aim of showing the effect of injecting L-Argnine acid on characteristics of semen, 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 (1.2-2) 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-Aarginine Acid in concentration 125, 250 and 375 mg /48 hour. Semen was collected by artificial vagina ،three times during the study. The results showed that the injection of L- Aarginine acid led to highly significant increase (p<0.01) in individual motility, Mass motility, live spermatozoa percentage, Dead spermatozoa ratio, sperm concentration, abnormal spermatozoa percentage. There were significant effects (p<0.05) for injection on the Mass motility of the sperm, where T4 and T3 were superior on T1 and T2 and T2 was superior onT1. A highly significant effect was also found (p<0.05) for injection in the individual motility where T4 and T3 was superior on T1 and T2 and T2 were superior on T1. There was a significant effect of the injection in concentration, where T4 was followed by T3 then T2 and finally T1. The percentage of live spermatozoa was superior for T3 and T4 on T1 and T2 and T2 was superior on T1. There was a high significant effect in Dead spermatozoa so T4 and T3 were superior on T1 and T2, T2 was superior on T1 with the lowest percentage of Dead spermatozoa. There was also significant effects of injection in the percentage of abnormal form sperm, as T4 and T3 was superior on T1 and T2 and T2 were superior on T1 with the lowest percentage of abnormal spermatozoa.
