Abstract

Goats are small ruminants that are reared by the rural community for financial income and nutrition. This study was aimed to determine the effect of vitamin C addition in tris–egg yolk extender on the lifespan of Sapera goat spermatozoa stored in 5o C. Semen was collected from 1.5 years old Sapera male goat. The ejaculates were diluted in Tris-egg yolk (T-EY) extender added with 0, 0.2, 0.3, and 0.4 g vitamin C/mL extender for T0, T1, T2, and T3 groups, respectively. The spermatozoa motility, viability, and morphological abnormality were assessed along with storage at 5° C. The result showed that spermatozoa motility was the highest (p <0.05) in T1 compared to other groups and qualified for AI use for up to 72 hours. In 24 hours storage, the spermatozoa viability was not significantly different (p >0.05) among the groups. The spermatozoa viability in the T1 group was the highest (p <0.05) among the groups along 48-96 hours of storage. The spermatozoa morphological abnormalities of the T1 group was the lowest (p <0.05) compared to other treatment groups in the range of 24-72 hour storage. In the control group (T0), the less than 5% spermatozoa morphological abnormalities (qualified for artificial insemination) were only in the 24 hours storage, while those of the T1 group were up to 72 hours. It could be concluded that the addition of 0.2 g vitamin C/100 mL T-EY extender maintained the quality of Sapera goat semen for 72 hours at 5°C.

Abstract

The purpose of this study was to determine the motility and viability of kampung rooster (Gallus gallus domesticus) spermatozoa in 0.9% Sodium chloride (NaCl) solution as an extender with the addition of egg yolk at different concentrations at cool temperature (5°C). This study was performed using two 1.5 years old healthy local roosters. Semen was collected through massage in the morning. The pooled semen sample was divided into four treatment groups. In the T0 group the semen was diluted in 0.9% NaCl, while in the T1, T2 and T3 groups the semen was diluted in 0.9% NaCl added with 5, 10 and 15% egg yolk. The results showed that the motility and viability of spermatozoa decreased when stored at cool temperatures for ten hours (p <0.05). Semen of roosters stored at 5°C in saline solution without the addition of egg yolks showed the lowest motility and viability of spermatozoa (p <0.05). The addition of egg yolk into the saline extender increased the motility and viability of spermatozoa. Concentration of 15% egg yolk in saline solution resulted in the highest spermatozoa motility and viability when stored for up to 8 hours (p <0.05). However, motility and viability of spermatozoa at 10 hours of storage were not significantly different (p >0.05) with the addition of 10% and 15% egg yolks. Therefore, it could be concluded that the addition of 15% egg yolk into a saline solution as an extender could maintain the motility and viability of kampung rooster spermatozoa when stored at 5°C for 10 hours.
