Abstract

This study aimed to determine the effect of adding 96% ethanol extract of green tea (Camellia sinensis) in egg yolk tris diluter on the quality of spermatozoa of Bali cattle (Bos sondaicus) after freezing. The samples were divided into four different treatment groups, which contained semen sample + 13% glycerol + each egg yolk tris diluter + green tea extract (P0) 0 mg/100 ml, (P1) 0,05 mg/100 ml, ( P2) 0,10 mg/100 ml, and (P3) 0,15 mg/100 ml. The variables observed included motility, viability, and spermatozoa abnormalities. Data were analyzed using OneWay ANOVA and continued with Duncan's test (p<0,05). The results showed that the P3 group had motility of 49,00 ± 2,15, viability of 61,92 ± 1,70, and abnormality of 4,24 ± 2,16 significantly compared to the other groups. In conclusion, the P3 group with the addition of 0,15 mg/100 ml of green tea could increase the motility, viability, and abnormal spermatozoa of Bali cattle.

Abstract

This study evaluated post-thaw semen quality and the proportions of X- and Y bearing spermatozoa in Bali cattle semen sexed by albumin of bovine serum albumin (BSA) column using two different gradients. In this study, frozen semen from a Bali bull was used, with three treatments: T0 (non-sexed frozen semen as a control), T1 (BSA 5%:8%), and T2 (BSA 5%:10%). The parameters observed were individual motility, viability, abnormality, concentration, total motile sperm (TSM), and sperm proportion.  The results showed that sperm motility in the upper fraction (UF) was highest under T2 (41.57%), whereas in the lower fraction (LF) it peaked under T1 (24.15%). Sperm viability was highest in the UF under T1 (57.69%) and in the LF under T1 (39.02%). The lowest abnormality was observed in the UF under T2 (4.64%) and in the LF under T1 (7.27%). Sperm concentration reached 30.14 million/straw in the UF under T2 and 22.27 million/straw in the LF under T2. Total sperm motility (TSM) was highest in the UF under T2 (12.57 million/straw) and in the LF under P1 (4.76 million/straw). The sperm proportions of the UF reached 75% X (T1) and the LF 81.71% Y (T1). Overall, the upper fraction obtained from the 5%:8% BSA gradient provided acceptable post-thaw sperm quality and adequate X/Y sperm enrichment, supporting its suitability for artificial insemination.

Abstract

Bali cattle, developed in Indonesia, are renowned for their high parasite resistance, adaptability, and reproductive health. This study aimed to evaluate the impact of age on the kinematic parameters of sperm in Bali bulls post-thawing. Semen samples were obtained by artificial vagina methods from three Bali bulls aged between 11 and 13 years, whose age was not indicated, and one bull of 9 years, which was used as a control. The experiment was conducted in December 2023 at the Singosari National Artificial Insemination Center in Malang, East Java, for sperm parameters, including viability, motility, and morphology. Computer-assisted sperm analysis was performed. The results showed a decline in sperm quality from fresh to frozen semen. Despite this, the semen from Bali bulls met the Indonesian National Standard, demonstrating the bulls' superior reproductive capabilities. Bulls aged 11–13 years exhibited variations in sperm quality; however, these differences may reflect individual variability rather than a consistent age-related trend. Semen from bulls aged over 10 years remain suitable for use, though regular testing is essential. Further research is needed to understand these variations and ensure optimal semen quality across different ages.
