Mastering five methods to improve the mating rate of cows

Strengthening breeding is the basis for raising cattle. There should be a simple shed to prevent summer heat in summer and a warm cowshed in winter. It is necessary to provide full-price nutritious feed for cows to ensure that they have enough to eat. It is necessary to do everything possible to increase the fatness of cows above 70% fat, and advocate grasping fat to promote emotion and full fat breeding.

Uterine cleaning is to ensure that the cleaning of postpartum cow uterus plays an important role in preventing postpartum placenta. The flushing solution can be diluted with oxytetracycline powder 3 to 4 grams, diluted with 0.9% normal saline 500 to 1000 milliliters, and poured into the uterus in batches until the washing solution is transparent.

Timely treatment of obstetrical bovine endometritis and vaginitis, after cleaning the uterus and injection of antibiotics to reduce inflammation, can be quickly cured. For anestrus cows with insufficient ovarian function, 0.5% neostigmine solution was injected into the cervix, 2 ml at a time, 3 times at an interval of 48 hours, and 1000 international units of gonadal hormone in serum of pregnant horse were injected at the same time of the second injection, which could restore the ovarian function of more than 80% anestrus cows.

Drug stimulation should not be negative. In order to improve the acceptance rate of cows and not wait passively for natural estrus, pregnant horse serum or triad hormone must be used for lactating cows and cows that have not been in estrus for a long time, and the rate of drug stimulation can be more than 70%.

Early isolation and early estrus isolation between mother and son was carried out after 7 days of age, and the calves were raised by artificial milk feeding. This method can promote the cow to be in estrus early.
