Banana حسام جاسن حسين بنانه PY - 2015 VL - 7 IS - 4 ملحق SP - 1 EP - 9 JO - Euphrates Journal of Agricultural Science مجلة الفرات للعلوم الزراعية SN - 20723857 AB - The aim of this study was to assess the effect of adding different levels of green tea (GT)infusion to semen extenders on the percentage of motility, viability and abnormality of ramsemen during storage at 5◦C for 0, 24, 48, 72, 96, 120 and 144 hrs after collection and dilution. Atotal of 16 ejaculates from 3 Awassi rams were gathered by artificial vagina and extended byTRIS extender. The GT infusion was added by 0, 2, 4 and 6 ml/ 100 ml of extender whichrepresents control group (C) and treatment groups (T1, T2 and T3) respectively.The results demonstrated a significant increase (P<0.05) in the percentage of sperm motilityfor each of the treatments T2 and T3 as compared with control group (C) for periods 0, 24, 48,72, 96 and 120 hrs, while the treatment T1 showed a calculation increased for the same trait ascompared with the control group (C) for all periods of experiment. The percentage of spermviability showed a calculation increased for all treated groups T1, T2 and T3 as compared withcontrol group (C) for all periods of experiment. Otherwise, the results appeared a significantdecrease (P<0.05) in the sperm abnormalities percentage for both treatments T2 and T3 ascompared with the control group (C) for all periods of experiment, whereas the treatment T1revealed a significant decrease (P<0.05) for both periods 120 and 144 hrs as compared withcontrol group (C) for the same trait. Therefore, it was concluded that adding GT infusion to theram semen extenders can be used to enhance semen characteristics which include motility andviability as well as reduce the abnormality of ram semen stored at 5°C.
