Cow breeding technique

Cows should be fed 2-3 times a day, drinking water 3 times, drinking water should be clean, fresh, winter water temperature should not be lower than 15 degrees, do not feed moldy, spoiled feed. In management, brushing and exercise should be strengthened, especially for first-born cows, in addition to brushing, breast massage should be carried out to facilitate postpartum calf lactation.

1. Management in the second trimester

In the later stage of pregnancy, that is, the 6th-9th month of pregnancy, the fetus grows rapidly and needs more nutrients from the mother. at the same time, the cow also needs to accumulate certain nutrients in the body to ensure the lactation after calving. At this time, should be in accordance with the feeding standards with diets, should be based on green feed, with appropriate concentrate. Concentrate choose agricultural and sideline products rich in local resources, such as wheat bran, cottonseed cake, dregs, etc., together with a small amount of corn and other grain feed. Special attention should be paid to mineral and vitamin supplements.

2. Perinatal feeding and management

Adjust the feeding according to the expected delivery date, and make good preparations for delivery. When pregnant cows are given more concentrate, the amount of concentrate should be properly controlled in the first 2-3 days of the expected delivery period, and the concentrate can increase the content of some wheat bran, reduce salt, do not feed beet dregs, distillers' grains, etc., and feed high quality hay.

3. Feeding and management during lactation.

Cow postpartum feeding is comprehensive, especially sufficient protein, minerals and vitamins in feed, coupled with reasonable exercise, cow uterus recovery quickly. Generally postpartum 4 weeks cervical external mouth atresia, about 40 days can be fully restored, in this estrus mating. The mating rate of beef cattle is higher at 60-90 days after delivery, so it is necessary to strengthen feeding and supplement feed in one month before delivery and two months after delivery, so as to make the cow pregnant again within 80 days after delivery, so as to ensure that the cow has one calf a year, so as to improve the survival rate of cow reproduction, reduce the feeding cost and improve the economic benefit of raising cattle.
