The longer the milking time, the better. The lactation period of the average cow is 305 days. However, in production, some farmers milk their milk from cows until they have no milk. This practice causes cows to over-consume nutrients in the body, making it more difficult for the cow to conceive, and thus affecting the increase in milk production. Milk must be milked during the milking period of the cows, and there must be a certain period of dry milk so that the cows have enough time to supplement their strength and loss of nutrition.
The more the fine material is fed, the better. As the economic benefit of the dairy cow for the farmer increases, many dairy cattle farmers love their own cows. Feeding dairy cows with diets containing a large proportion of concentrates often leads to the metabolism of dairy cows. Diseases and other nutritional diseases. In dairy cattle, ruminants, the proportion of roughage in their diet should generally not be less than 60%.
During the dry period, the dairy cows in the milk-reducing period are required to provide nutrients in the dry-milk period after the calving of the calving and the loss of nutrients in the body, as well as the need for nutrition such as pregnancy and embryonic development. Many dairy cattle households think that they should not feed milk even when they are not milking, and drastically reduce the amount of fine feed. As a result, they cause lower-quality puberty before labour, laborious and time-consuming calving, low milk production, and weak yak production. In addition to the appropriate amount of feed, the amount of concentrate in dry milk should be 0.8% to 0.9% of the weight of the cow.
Cows strong disease resistance Sanitary disinfection is inconsequential In fact, cows are very sensitive to the environment, do not brush cattle body for a long time, can not guarantee the dry, ventilated, hygienic cowshed, will affect the health of dairy cows or directly affect milk production.
Early mating and early delivery and early milking are the reasons for early milking and early gains. Many dairy farmers breed when calves are born less than 18 months and their weight is less than 250 kg. This often seriously affects the pregnancy of cows. Quality can easily lead to dystocia and cause premature aging of cows. The correct breeding time should be around 18 months of age and weighing about 400 kg.
Nurturing at ease and worrying Many dairy farmers raise their cows with ropes and necks regardless of the season or because of lack of scientific knowledge. Directly limit the movement of dairy cows and affect their constitution. Feeding on the gizzards of pregnant cows during pregnancy will affect the growth and development of the fetus. At the same time, it may easily cause obstetric diseases such as difficult labor for the cows and retention of placenta.
