Method for improving pregnancy rate by massaging uterus during dairy cow semen deposition

The invention relates to the technical field of dairy cow procreation, in particular to a method for improving the pregnancy rate by massaging the uterus during dairy cow semen deposition. The pregnancy rate of dairy cows is improved, and the method for improving the pregnancy rate by massaging the uterus during dairy cow semen deposition is provided. The uterus is massaged before and after semen deposition is carried out, and uterus peristalsis is promoted; when massaging is carried out, the right hand is curved, the five fingers are loosened to be folded, massaging is repeatedly carried out for one minute from the cornua uteri to the cervix, or massaging is repeatedly carried out for twenty times to thirty times; then the cervix is held with the right hand, a semen deposition device with sucked seminal fluid is poured into a cervix pipe with the left hand, an injection syringe is pushed with the right hand, and the seminal fluid only needs to enter the bifurcation position of the cornua uteri. According to the method, the uterus is massaged while semen deposition is carried out, the uterus peristalsis is promoted, and the pregnancy rate is accordingly improved; the uterus is massaged, so that the rectum is loose, and pipe entering is easy. Through tests for 280 dairy cows in local, after processing with the method, the effect is obvious, the pregnancy rate is obviously improved, and statistics can reach more than 90%.
