Although the efficiency of raising dairy cows is affected by market factors such as feed and fresh milk prices, farmers can still obtain better economic benefits if they can fully increase milk production and reproduction rates and reduce mortality. Pay attention to the following issues: The varieties with good varieties are the basis for high yields. When farmers purchase dairy cows, they must choose from larger dairy farms or more familiar cattle farmers to avoid buying back low-yield cows, fake cows and sick cattle. Uterus-free cows cause unnecessary economic losses. It is advisable to expand the herd to breed her own breed and to choose the remaining offspring of high-yielding dairy cows. The breeding should be done with frozen sperm of the best Holstein breeds produced by regular manufacturers in order to improve the production of cows. Performance, improve milk production. Feed comprehensive nutrition feed, is an important guarantee for the full potential of dairy cow production, with the diet should be based on different physiological stages of dairy cows, different physical fitness and different milk production levels, the timely adjustment of various nutrients needs, In accordance with the nutrition standards to meet. Feed nutrition should be comprehensive, good palatability, variety of species. It is forbidden to feed the moldy, frozen, pesticide Dyed feed. The level of management and management is not only directly related to the speed of the growth and development of dairy cows, the level of production performance, but also related to the health of dairy cows.

Without exercise, it will not only reduce milk production, but also lead to Some diseases occur. At the same time, swabs should be brushed every day to keep the body surface clean, promote blood circulation, enhance disease resistance, and increase milk production. Propagation and reproduction technology is an important part of dairy cow production. Breeding, normal milk production levels, and the economic benefits of cows are not affected by reproductive technology. It is necessary to start breeding when the cows are 16 to 18 months old and have a body weight of 350 kg or more. It is important to pay attention to the nutrient supply of postpartum cows, especially The supply of protein, energy, calcium, phosphorus, vitamins, and trace elements.
