A study was carried out to examine the effects of seasons and environmental conditions (ambient temperature; AT, relative humidity; RH, temperature-humidity index; THI, and sunshine hours; SH) on semen quality of Senduro goats in the tropical climate. A total of 252 ejaculates semen were collected from 3 Senduro bucks from January to December 2017. The semen quality was then evaluated including semen volume (VOL), sperm concentration (CONC), total sperm output (TSO), individual motility (IMOT), before freezing motility (BFMOT), postthawing motility (PTMOT). The acceptance rate of fresh semen (ARFS), before freezing semen (ARBFS), and postthawing semen (ARPTS) were also calculated. The results showed the seasons had a significant effect (P < 0.05) on CONC, IMOT, and PTMOT, with the higher value, was recorded during rainy than the dry season. It was observed that the Senduro buck was tolerable with the change in AT, RH, THI, and SH because most of the semen traits remain unchanged (P > 0.05) among these groups. Moreover, it was interesting that the maximum PTMOT was achieved at high AT and THI. In conclusion, the rainy season has more preferred ejaculate semen than the dry season, but the semen collection is still acceptable to be carried out throughout the year. This study also suggests that Senduro bucks have good adaptability to tropical conditions.
