The 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 earns five or six thousand yuan, which is more than the per capita income of farmers in the general area. Dairy cows can also make full use of crop stalks to return the land to the field. Moreover, dairy cows produce the highest amount of milk in ruminants, and their feed conversion rate is the highest. From the energy and protein produced per hectare of land, it is also the highest among dairy cows. Therefore, vigorously developing dairy cow breeding is a good project supported by the government and benefited farmers.
However, the development of dairy cows must have a good foundation cow. Dairy cows, the kings of high-yielding dairy cattle breeds, which are generally considered to be the world's most popular breeds, are still unbalanced in their distribution in China. They are mainly concentrated in the surrounding areas of major cities and large dairy cow bases. Farmers who want to buy a high-yielding Holstein dairy cow usually need to invest 1 to 2 million. Under natural conditions, dairy cows can only produce 3 to 4 females. Although embryo transfer can speed up reproduction and improvement, at present, the cost of transplanting a female parent is above 10,000 yuan. Therefore, it is not the best way to vigorously develop dairy cow breeding, and rely on huge sums of money to introduce excellent animal husbandry or embryo transfer. Only by fully exerting and tapping the breeding potential of high-yield dairy cows, allowing high-yielding dairy cows to produce more females, speeding up the reproduction rate of seed groups, and using less input and more output, can the dairy cattle breeding industry continue to develop in a healthy and sustainable manner.
Rapidly increase the breeding rate of dairy cows, in addition to focusing on strengthening regular feeding and management, doing estrus identification, and timely mating, we must also make full use of new technologies and introduce new products. We must truly understand that science and technology are the primary productive forces. At present, many farmers do not pay attention to the investment in science and technology, there is no long-term development plan and goal, which will be difficult to adapt to the development situation after the accession to the WTO. Recently, there have been many new breakthroughs in the breeding and breeding of dairy cows, and the majority of farmers can choose to apply according to their respective conditions, such as yak cold shelter and early weaning techniques, dry dairy cows fed yin and yang ion balanced diet technology, Embryonic sex identification and embryo cutting techniques, sexually controlled cryopreservation techniques, etc.
It is particularly worth mentioning that the promotion and application of the cow immunogenic technology for cows with prolific vaccines has brought good news to farmers. Using prolific vaccines to actively immunize cows and control their use, the cows can produce 2 to 4 yak calves with the same sex. If the use of sexual control of frozen sperm (or gender control fluid), you can completely achieve the birth of "male" and "female" completely controlled by the artificial and quickly improve the high-quality high-yield dairy cattle, beef cattle breeding desire. Its reproductive efficiency is 5 to 10 times that of the natural state, and the effect is encouraging and encouraging. Due to its low cost, people in the industry are generally optimistic.
