Abstract

The constraint of cattle development in Indonesia is low productivity, which was caused by low reproduction efficiency. Unestroes and difficulty of heat detection influenced to the calving interval. This calving interval is one of the causal factors of low reproduction efficiency. The efforts to solve this problem are to control and to predict heat period using synchronization technology. Synchronization technology on catlle has been developed from corpus luteum enucleated, utilizing of gonadotropin, progesteron, estrogen, prostaglandine and modification of those hormones. Application method for synchronization could be done by intra musculair, subcutan implantation, intra vaginal and mixed with food. Each method has its own strength and weaknesses. However, to handle anestroes cases is more effective to use combination of progesteron, PGF2α and estrogen. In order to obtain reproduction efficiency it is suggested to take the anestroes in hand as soon as possible.   Key words : Cattle, synchronization estrous

Abstract

The quality of frozen semen will be reduced if high oxidative metabolism activity in semen occurs, due to the formation of free radical compounds causing lipid peroxidation reaction on sperm plasma membrane. Lipid peroxidation occurs due to the exposure of semen to the oxygen during handling. Lipid peroxidation can be prevented by the addition of antioxidant compounds such as vitamin C, vitamin E, glutathione, and b-carotene, in the semen extender. Results of some researches showed that the addition of various antioxidans in extender can improve the quality of frozen semen of various animals. Key words: Antioxidant, free radical, lipid peroxidation, frozen semen
