“…The semen quality was measured directly upon collection, including semen volume, sperm concentration, total sperm number, individual sperm motility, post-thawing sperm motility and frozen semen production. The semen volume was measured using a scaled vial (Isnaini et al, 2019a). Sperm concentration was measured using the spectrophotometric method (Isnaini et al, 2019a).…”

The success of artificial insemination highly depends on the semen quality, in which it may significantly associate with the environmental factor. However, the information regarding the seasonal effects on semen quality of Pasundan bulls is still scarce. This study aimed to examine seasonal variation in semen quality of Pasundan bulls in their native environment. A total of 203 ejaculates produced by two Pasundan bulls aged at four years old were used in this study. The bulls were kept under standard management conditions in Lembang Artificial Insemination Center. The results showed that mean values of semen volume, sperm concentration, total sperm number, individual sperm motility, post-thawing sperm motility and frozen semen production of Pasundan bulls were 5.7 mL, 1.17 billion/ml, 6.57 billion/ejaculate, 62.1,0 40.6 and 272% doses/ejaculate, respectively. Semen volume, individual sperm motility and post-thawing sperm motility were not affected by different seasons (P>0.05). Whereas, the significant reduction of sperm concentration (P<0.05), total sperm number (P<0.01) and frozen semen production (P<0.01) were observed in the dry season as compared to the rainy season. The minor change in ambient temperature, maximum ambient temperature, relative humidity and temperature-humidity index were detected between seasons. On the other hand, about 52% greater sunshine duration was detected in the dry season compared to the rainy season. In conclusion, the semen quality of Pasundan bulls is reduced during the dry season, which is considerably associated with the increase in sunshine duration.

“…The good semen quality is a critical point to ensure the success of the AI program. While semen quality itself is highly dependent on climate factors such as Ambient Temperature (AT), Relative Humidity (RH), or their combination as Temperature-Humidity Index (THI) (Snoj et al, 2013;Bhakat et al, 2014;Valeanu et al, 2015;Sabés-Alsina et al, 2017;Isnaini et al, 2019a;Isnaini et al, 2020;Isnaini et al, 2021a). Among those mentioned factors, AT seems to be the main variable which may affect semen quality.…”

Semen quality is a critical point to ensure the success of the artificial insemination program. One factor which highly determine the semen quality of bulls is climatic conditions. The purpose of the present study was to evaluate the association between climatic factors and fresh semen quality parameters in Madura bulls. A total of 1583 ejaculates which were collected from 5 Madura bulls from January 2014 to December 2018 were included in this study. Semen quality parameters such as semen Volume (VOL), sperm Concentration (CONC), Total sperm (TOT), sperm Motility (MOT) and Straw production (STR) were directly evaluated upon collection and then correlated with climate factors such as mean and maximum ambient temperature (ATmean and ATmax, respectively), Relative Humidity (RH) and Temperature-Humidity Index (THI). The results demonstrated that the month of semen collection had no effect (P>0.05) on VOL, CONC and TOT. However, MOT and STR were differed (P<0.05) among semen collection time, with the peak value was observed in March. Among climatic variables studied here, AT max was the most sensitive factor associated with sperm quality parameters. ATmax value at the same month as semen collection had negative significant correlation (P<0.05) with TOT and STR, while at one and two months before semen collection was consistently had negative significant correlation (P<0.01) with CONC, TOT and STR. It could be concluded that the maximum ambient temperature is the most responsible climatic factor affecting loss of straw production in Madura bulls.
