But further study found that their number of born and farrowing rate do not show significant difference. The main reasons for lower reproductive performance in buffalo is due to its relatively late sexual maturity hence postponing the age of first pregnancy, in addition, the long gestation period and longer period between successive pregnancy also results in the lower reproduction performance. In order to improve the reproductive performance in Taiwan buffalo, the reproductive physiology need to be investigated and assessed. Analysis and monitoring reproductive hormones in buffalo can predict their estrous cycle, early prediction of pregnancy and shortening the period between successive gestations. By analyzing reproductive hormones(estrogen, progesterone, cortisol etc.), we can assess the possibility of advancing the time of sexual maturity and the age of the first pregnancy. Because of the reduction of the buffalo industry in Taiwan, the information related to reproductive hormones of Taiwan buffalo is relatively scarce. So, the purpose of this proposal is to establish the basic data related to reproductive hormones of buffalo, then further setting up relevant physiological database of Taiwan buffalo. This can provide reference and consulting for relevant research later.沼澤型水牛生育力繁殖內泌素swamp buffalofertilityreproductionhormone
