1. During the feeding process, the diet should be balanced and scientific feed formula should be adopted to ensure the supply of protein, vitamins, minerals and other elements.

2. Cattle should ensure clean drinking water, fresh feed, strengthen exercise, wipe the cattle body to promote blood circulation, timely repair deformed hooves, keep the cowshed clean and hygienic, and regularly disinfect and repel insects.

3. Through scientific nutrition collocation and feeding management of dairy cows in different periods, when calves grow to 6 months old, they should pay attention to the improvement of body volume, rumen function and survival rate, colostrum feeding, high-quality forage supply and fine management.

4. Due to the low protein and energy supply of roughage, dairy cows should pay attention to the timely supplement of concentrate in the growth process to ensure healthy growth and balanced nutrition.

5. There is little green feed in winter, and farmers pay attention to the supply of vitamin A. 60 days before the production of basic cows, concentrate 1.0 ~ 1.5 kg is supplemented every day; Supplementing concentrate 1.5~2.5kg every day after delivery120 days is convenient for dairy cows to produce milk and improve the conception rate of mating.

6, cowshed environment should also ensure good lighting and ventilation, but also control the temperature of the cowshed, keep it clean at ordinary times, and keep the cowshed hygienic. The site selection should be based on the local climatic conditions, because the climate has a great influence on the reproduction of cattle. Although the estrus rate is high in hot and rainy seasons, the pregnancy rate is low. The pregnancy rate from July to August sometimes only reaches about 30%, so we should pay attention to heatstroke prevention and cooling in daily management.

Extended data:

With the continuous improvement of people's quality of life, people's demand for beef is getting higher and higher, and the development of animal husbandry has promoted the process of farmers getting rich quickly by relying on animal husbandry to some extent. Therefore, it is necessary to constantly study and improve the management methods of dairy cows, so as to make the management methods more scientific and effectively improve the efficiency of aquaculture.
