While strengthening the management of pregnant cattle and comprehensively meeting the nutritional needs, timely injection of vitamin A and vitamin E into pregnant cattle can enhance the vitality of pregnant cattle embryos in the uterus, promote embryonic and fetal development, and enhance the reproductive rate. It is also an effective way to reduce the early death of dairy cow embryos.
1. Injecting 500,000 IU of vitamin A into pregnant cows on the day of fertilization and 5 days to 6 days after fertilization, the pregnancy rate of fertilized cows can be increased by 19.5% compared with no injection. Even if the first insemination was unsuccessful, more than 80% of the cows who did not have successful fertilization re-estrus after 18 days to 25 days, compared with only 30% of the unwounded cows who did not receive vitamin A. The cow rekindled during this period. It can be seen that injecting vitamin A into pregnant cows not only improves and improves the reproductive rate of the cows, but also has a good effect on the later sexual cycle.
2. Vitamin E (250 mg each) on the 2nd, 6th and 12th day after fertilization, respectively, can increase the first-time fertilization rate by 10.5% compared with non-injected cows.
Third, a vitamin E (dose of 500 mg) is injected 15 minutes to 20 minutes after the cow is fertilized, which can increase the pregnancy rate of the first-fertilized cow by 14.5% compared with the non-injection. In addition to regulating sexual function and increasing reproductive rate, vitamin E can also be used to treat diseases such as habitual abortion, threatened abortion and infertility, which can reduce the excitability of pregnant uterus and protect the safe growth of the lamb.
