| Abstract: | In this paper, the problems existing in current use of reproductive hormones in dairy farms were discussed. The problem of inappropriate use of chloroprostaglandins in dairy cows reproductive production was analyzed to propose the correct method to use chloroprostaglandins. The misconception that the regular ejaculation during estrus was better than the spontaneous estrus was corrected. The reasons for no any effect of the injection of prostaglandins in cows at early stage after postpartum and the correct method of administration were stated, and the precautions for use of reproductive hormones in the reproductive production of dairy cows was put forward, which provided important guidance for the improvement of reproductive efficiency of dairy cows. |
