- Abstract
This research aimed to determine the effect of gonadotropin-releasing hormone (GnRH) in improving semen quality and hormone testosterone in Nubian goats. The experimental design was a 3x3 Latin square with the experimental animals that received a physiological NaCl injection as a control (T0), 50 μg GnRH (T1), and 100 μg GnRH (T2). The semen samples were collected using an artificial vagina at 24 hours after treatment, and then semen characteristics were evaluated both macroscopically and microscopically. Subsequently, the blood samples were collected at 60 minutes after the injection of GnRH for the analysis of testosterone concentration using the enzyme-linked immunosorbent assay (ELISA) method. The observations showed a cream coloration with thick consistency in the semen collected from all treatment groups. In addition, the average (±SD) of semen volume (mL), concentration (106), motility (%), viability (%), abnormality (%) of spermatozoa and testosterone levels (ng/mL) in the T0 vs T1 vs T2 groups were 1.8 ± 0.52 vs 1.5 ± 0.70 vs 2.6 ± 1.63 (P > 0.05), 807 ± 409.98 vs 895 ± 509.73 vs 1,215 ± 270.14 (P > 0.05), 37.00 ± 0.333 vs 34.00 ± 0.309 vs 65.00 ± 0.110 (P > 0.05), 63.00 ± 0.144 vs 59.00 ± 0.121 vs 57.00 ± 0.145 (P < 0.05), 33.00 ± 0.382 vs 15.00 ± 0.199 vs 7.00 ± 0.040 (P > 0.05), 13.16 ± 9.37 vs 28.13 ± 1.21 vs 33.13 ± 2.30 (P < 0.05), respectively. It was concluded that GnRH treatment is capable of reducing spermatozoa abnormalities and increasing the testosterone concentrations of Nubian goats.
