Spring is the peak period of cattle mating, but climate change is unpredictable and the incidence and mortality of cattle are extremely high. Therefore, it is necessary to strengthen the feeding and management in the spring, scientifically fertilize the fetus, ensure the safety of the mother and child, and increase the reproduction rate. Empty cow breeding Every day, each cow is fed with 50 grams of salt and 1-2 kilograms of mixed concentrates such as barley, corn and soybeans. After drinking water first, feed the grass, wait until the cows have eaten until the five or six percents are full, feed the mixed concentrate, and then drink the salt water, and wait until the cows rest for 15-20 minutes before going out. After grazing, prepare enough water and night grass to allow the cow to freely drink and eat. When the cow is too fat, it can increase the amount of jousting, and feed more coarse material and juicy feed. If you are too thin, make up the fine material and green feed, and strive to achieve a medium sensation before breeding.

The period of estrus in cattle lasts 18 hours, generally lasting 12-22 hours, and ovulation occurs 10-15 hours after the end of estrus. Therefore, the suitable mating time of the cow is: if the estrus occurs in the morning, it will be bred at 8-10 pm on the same day, and will be supplemented once at 7-8 am the next morning; if the estrus is in the afternoon, the breeding will be on the next morning and the afternoon or evening will be used once. Induction of ovulation in cows The cow has normal genitalia but does not have estrus or misses the estrus period. It can use urine of pregnant women, estrodrol triadogens, etc. to induce ovulation of estrus in cows, and timely fertilize and prevent pregnancy.
