Objective: The aim of this study was to ascertain the effects of adding green tea extract (GTE) to skim milk-egg yolk (SM-EY) extender on both the quality of post-thawed bull semen and the pregnancy rates of the recipient cows.Methods: Twelve ejaculates from four Simmental bulls, aged 3 to 5 years and weighing 900 to 950 kg, were diluted SM-EY extender, added with 0, 0.05, 0.1, and 0.15 mg GTE/100 mL extender and then frozen. After four weeks storage in liquid nitrogen, the sperm were thawed and evaluated for viability, motility, intact plasma membrane (IPM), and DNA fragmentation. Meanwhile, the estrus cycles of 48 recipient cows were synchronized by intramuscular administration of a single injection of 5 mg prostaglandin F2α. Estrus cows were divided into four equal groups and inseminated artificially 18 to 20 h after the onset of estrus by using semen from each extender group. Pregnancy was diagnosed by measuring serum progesterone levels at 21 days, followed by transrectal palpation 90 days after insemination.Results: The findings revealed that adding 0.1 mg of GTE/100 mL extender produced the highest percentages of sperm viability (70.67%±1.75%), motility (69.17%±1.47%), and IPM (69.23%±1.21%) and the lowest percentage of DNA fragmentation (3.00%±0.50%). The pregnancy diagnosis revealed that all cows (36/36) inseminated using frozen semen in GTE addition extender were pregnant (pregnancy rate 100%), whereas the pregnancy rate of the control group was 83.33% (10/12).Conclusion: It may be concluded that 0.1 mg GTE/100 mL extender yields the best quality of spermatozoa and that all variants doses of GTE in extender produce a higher pregnancy rate among recipient cows.

The purpose of this study was to determinated the effect and the best concentration of greentea extract in skim milk and egg yolk diluent for quality sapudi sheep spermatozoa were measured in motility, viability and intact plasma membrane that was stored on cold temperature. The semen was devided into four groups; skim milk and egg yolk diluent, 0,5% green tea extract in skim milk and egg yolk diluent, 0,1% green tea extract in skim milk and egg yolk diluent, and 0,15% green tea extract in skim milk and egg yolk diluent. Spermatozoa quality was observed day 1, day 2, day 3, day 4 and day 5 after being diluted. The data obtained was analyzed with the Analysis of Variant (ANOVA), followed by multiple range test duncan. The results showed that the highest percentage of motility, viability and intact plasma membrane derived from green tea extract 0,15% on skim milk and egg yolk diluent  for 1 day storage is 86.66b ± 2.58, 92.00b ± 1.78, and 74.16b ± 3.25. The lowest percentage of motility, viability and intact plasma membranes was obtained from the skim milk and egg yolk diluent for 5 days storage is 43.33a ± 6.05, 56.50a ± 3.08 and 28.33a ± 2.80. The conclusion of this study is the addition of 0.15% green tea extract in a skim milk and egg yolk diluent can maintain the quality of sperm for up to 5 days of storage at cold temperatures.
