First, disinfection awareness is not strong. Many dairy farmers believe that cows have strong disease resistance and do not need to pay attention. As a result, cows often die. Doing a good job of disinfection is the basic link for raising dairy cows. In winter and spring, the cowsheds and the surrounding environment should be disinfected once a week, summer and autumn should be disinfected twice a week, and feed and drinking water must be sanitized to prevent feeds from mildew. .
Second, eager to achieve success. Many dairy cows breed when the yak is not 18 months old and weighs only 250 kg. As a result, the first child often suffers from dystocia and rupture of the vagina, affecting normal reproduction of the next child. Therefore, the cattle-raising households can't be eager to seek success, and the management of breeding and management of yaks and bred cattle should be strengthened. Only when the yak is sexually mature and the body weight reaches 350-400 kg can the initial allocation be carried out.
Third, over milking. The lactation period of dairy cows is 305 days. Some dairy cows ignore the physiological cycle of dairy cows. They stop milking cows from being post-natal until they have no milk. As a result, cows consume excessive nutrients, making it more difficult for pregnant cows to conceive, which in turn affects The overall milk yield of dairy cows increased. Therefore, milking can only be done during the lactation period to allow the cows sufficient time to make up for the loss of nutrients in the body.
Fourth, dry milk reduction. Dairy cows produce lactation through lactation, and the loss of nutrients in the body, together with the need for nutrition in pregnancy and embryonic development, needs to be restored during the dry period. Many dairy cattle farmers mistakenly believe that they should feed poorly fed feed when they are not milking. As a result, the amount of concentrate feed was significantly reduced, resulting in poor pre-production pupa, time-consuming and laborious calving, weak oxen, and low milk production by cows. It can be seen that, in addition to just a few days after the dry milk and just a few days before the onset of production, the cows can appropriately reduce the feed amount of the concentrates. It is advisable that the amount of concentrates to be fed on the dry period be 0.8% to 0.9% of the weight of the cows.
Fifth, the pile support. Most farmers use their ropes to feed their necks regardless of seasons, which not only limits the activities of calves, but also seriously hinders the growth of calves. As a result, dairy cows are difficult to produce, there are no placebos, no obvious estrus, and poor health. . Calves should be allowed to move freely within the calf pens and feed regularly to promote the metabolism of the cows, increase appetite, maintain normal reproduction, and increase disease resistance.
Six, do not brush cattle body. The cow's skin is sensitive to the outside dust. When the dry hair is attached to the hair, the cow will feel uncomfortable. The tongue is often used, and the body is used to wipe the wall and trough to relieve the body's itching, which seriously affects the health of the cow. Therefore, we should keep the body clean and hygienically. Every day we must use a brush to wipe the body of the cow once.
