Disinfection awareness is not strong: Many dairy cattle households believe that cattle have strong disease resistance and do not need to pay attention to it. As a result, cows often die. We must conscientiously do a good job of disinfection, winter and spring weekly disinfection of the cowshed and the surrounding environment, summer and autumn disinfection twice a week, and do feed, drinking water hygiene, prevent mildew feed. Anxious for success: Many dairy cows are mated when the yak is not born 18 months old and weighs only 250 kg. The first child often suffers from dystocia, and the pudendal rupture, which affects the normal reproduction of the next child. Therefore, the cattle-raising households can not be eager to achieve success, should strengthen the breeding and management of yaks, breeding cattle, to reach 350 to 400 kg, before the initial allocation. Excessive milking: The average lactating period of dairy cows is 305 days. Some dairy cows stop the cows from being post-harvest until there is no milk. As a result, the cows consume excessive nutrients, which makes it more difficult for the cows to get pregnant and affect the increase of milk yield. Therefore, milk must be milked during the lactation period to allow the cows sufficient time to make up for the loss of nutrients in the body. During the dry period, the milk consumption is reduced: In addition to the days when the cows have just dried milk and the days before the birth, the cows should appropriately reduce the feeding amount of the concentrates. The dry cows' feeding amount should be 0.8%~0.9% of the cow's weight. Pile-up support: The calves should be allowed to move freely in the calf pens, feeding regularly to promote the metabolism of the cows, increase appetite, maintain normal reproduction, and increase disease resistance.
