Abstract

This study investigated the effects of gonadotropin-releasing hormone (GnRH) administration on luteinizing hormone (LH) concentrations and libido in pubertal male Kundhi buffalo calves. Objective: To determine the effects of GnRH administration on LH concentrations and libido in pubertal male Kundhi Buffalo calves. Methods: Eight calves, aged 16 months, were divided into two groups: Group A (treatment n=4), administration of GnRH analog (25ug lecirelin) and Group B (control n=4), there is not any administration. Each group consisting of four calves under a semi-intensive management system, the calves were fed a diet including 2 kg/day/calf of cotton seed cake, along with wheat bran, wheat straw, and green fodder, at the Department of Animal Reproduction, Faculty of Animal Husbandry and Veterinary Sciences. Results revealed a significant temporal change (P < 0.000) in the mean circulating concentration of LH over time after the intramuscular administration of GnRH analog (25ug lecirelin, Fatro®, International) three times. Results: The LH pulse was highest after the second GnRH dose (29.46±1.828), with significant differences in libido parameters, including mounting activity, erection, and sniffing, between the treatment (Group A) and control (Group B) groups. Statistical analysis revealed significant effects of episodic GnRH administration on both LH concentrations and libido. Conclusion: The episodic administration of GnRH significantly increased LH concentrations and improved libido in pubertal male Kundhi buffalo calves.
