“…Testosterone secretory capacity before and after GnRH treatment can change plasma concentrations of LH and testosterone in bulls aged 20 months with normal semen (Sakase et al, 2018). Nevertheless, the study by Mondal et al (2019) stated that LH hormones and peripheral rhythm of testosterone could not be used to detect libido problems in Zebu bulls.…”

Administration GnRH to bulls is expected to improve semen quality. This study aims to determine the effect of giving the hormone GnRH in various doses on the quality of semen in Ongole Crossbreed (OC) bulls. The study used 18 OC bulls with three GnRH treatments, A (one dose/5ml/animal), B (half-dose/2.5ml/animal), and C without GnRH. The GnRH was administered once by intramuscular (IM) injection. Semen collection was carried out for 16 weeks; divided into two periods, namely 8 and 16 weeks after GnRH administration. Parameters that were measured include volume, acidity, color, consistency, mass motility, individual motility, spermatozoa concentration, viability, and libido. Data were analyzed using the ANOVA test. The results showed that the volume and pH of semen did not differ in all treatments, but treatment A showed cream color and thick consistency over treatments B and C. The mass motility and sperm concentration of treatment C with the dose and period of GnRH administration resulted in the lowest values significantly different (P<0.05) than treatments A and B, so it affects the total spermatozoa and the total motile spermatozoa. Sperm viability in one dose of treatment A resulted in the highest value significantly different (P<0.05) than treatment B and C with spermatozoa viability of 78.42±2.46% (A), 76.14±1.52% (B), and 65.57±8.26% (C) in the 16 weeks. Nevertheless, the abnormalities and libido between treatments and different periods did not show any difference. It was concluded that the administration of GnRH at a dose of 5 ml/IM can increase the mass motility, individual motility, sperm concentration, total spermatozoa, total motility of spermatozoa, and viability in Ongole Crossbred bulls.

“…A male's fertility rate and quality of semen will decrease if it is not followed by adequate libido (Kumar et al 2011). Libido is an expression of engodenous control, especially related to LH or testosterone levels in the blood, as well as stimulation of exogenous through physiological processes and also reproduction experience (Mondal et al 2019). Libido of a male can be assessed ranging from no response to climbing the teaser to actively climbing by making more than one ejaculation (Menegassi et al 2011).…”

“…In dromedary camels, the basal testosterone level is about 3.0 ng/ml (Monaco et al 2015). In zebu males, the average basal concentration of testosterone is 3.27 ng/ml which are classified as low libido, while normal libido can reach 20 ng/ml (Mondal et al 2019), in bulls 9.4 ng/ml (Kowalczyk et al 2021), in holstein bulls 7.7 ng/ml (Devkota et al 2011).…”

Bali cattle are one of the original Indonesian germplasm, which in its development were found to be hornless or polled. Polled are Balinese cattle whose horns do not grow naturally, but have the same characteristics as those with horns. However, there are indications that polled have a lower libido. The purpose of this study was to determine the characteristics of libido and testosterone concentration after gonadotrophin releasing hormone (GnRH) injection. In this study each of 7 male polled and horned Bali cattle aged 3.5-6 years were used. Libido characteristics were observed by recording the first time the male fondled the teaser until ejaculation, while the testosterone concentration was measured using blood plasma taken on day 0 or before injection, day 7th, and day 14th after GnRH injection. Testosterone analysis used enzyme linked immunosorbent assay (ELISA) method. The results showed that the libido of polled was not different (P>0.05) compared to that of the horned on the 0, 7th and 14th days after GnRH injection. However, in polled on the 7th day after GnRH injection, it was significantly lower than on day 0 and 14, but on day 0 it was not different with day 14. Testosterone concentration on day 7 after injection of GnRH was not different (P>0.05) compared to day 0 both in polled and horned bulls, but on day 14 after injection was significantly higher (P<0.05) in horned than polled. In conclusion, polled and horned Bali bulls had high libido with a score of +1, but on the 7th day after GnRH injection, polled had lower libido than horns. The testosterone concentrations of polled and horned on day 7 after GnRH injection were not different compared to day 0, while the 14th day was higher in horned bull.
