The annual net income of an acre of wheat or Corn and other food crops is only one or two hundred yuan, and raising a high-yielding dairy cow at least yields five or six thousand yuan, even more than the average per capita income of the average farmer, and the dairy cows can make full use of the crop stalks. To return to abdomen and return to the fields, many workers in the Holstein-based Holm Holstein Holstein dairy farm in Inner Mongolia rely on aquaculture cows to earn more than 100,000 yuan each year. Therefore, vigorously developing dairy cow breeding is a good project for the government to support farmers. However, as a new small and medium-sized farm and professional household, it is unrealistic to expand the breeding scale by investing huge sums of money to purchase breeding cows due to low capital and low starting point. Is there a more affordable way? In the natural state, cows can only produce 3 to 4 females in their lifetime. How to give full play to and exploit the breeding potential of good females and allow the high-quality and high-producing cows to produce more females has always been people's good wishes and goals. In the implementation of the Holstein cows' large-scale feeding process, the base used reproductive and immune technology to develop a multi-producing vaccine for cows. The rapid expansion of the twins of fine-bred dairy cows was tested and the desired results were achieved. Use a prolific vaccine to actively immunize cows and control their use. The cows can produce 2 to 4 yaks in a single birth, and the gender is uniform, so as to effectively avoid the disadvantage of having 95% of the cow's heterosexual twin fetuses without fertility. The specific use method is: In the cow estrus adaptation period intramuscular injection of 30ug ~ 40ug multi-producing vaccine, and then artificial insemination, the production of 2 to 4 fetal calves success rate of up to 90%. When artificial insemination is combined with the application of controlled spermatozoa (or gender-controlled fluid), the desire of the “male†and “female†to fully control artificially and rapidly increase the reproductive rate of the high-quality and high-produce dairy cows can be completely realized, and the speed of their reproductive offspring can be achieved. It is 4 times to 8 times that of the natural state, thereby rapidly increasing the number of good breed cows. The test results show that the comprehensive application of the above technologies can greatly improve the breeding ability of elite breed cows with significant results and low costs. The economic and time benefits are very considerable, far more affordable than embryo transfer, and are more suitable for small and medium-sized farms. Promotion and application of professional households.
