Raising cows to avoid 10 big mistakes

At present, due to lack of breeding techniques or unilateral pursuit of milk production, some farmers have many wrong practices in the management of dairy cows, and this will inevitably affect the overall aquaculture benefits. To this end, the author summarizes the 10 errors in dairy farming as follows, hoping to draw everyone's attention and try to avoid it.

First, early mating early benefits

Many farmers bred cows in less than 16 months and weighed less than 300 kilograms. The consequences are often difficult to produce in first-child births, and the growth and development of the cow itself is also affected, so that the lifetime birth weight is not high. The initial time of dairy cows should be based on body maturation. The initial weight should be 350-400 kg.

Second, calves do not have milk pots for the first half of their lives

After calf, most calves use pots or pots to feed calves. As a result calves suffer from indigestion and diarrhea. Because of the use of small barrels or pots to feed milk, certain digestive organs of calves cannot be exercised, and the rumen microflora is difficult to establish, which can easily lead to digestive diseases in calves.

Third, yak grazing material

Naturally, when eating oysters at the time of eating, it is considered that the yak's digestive organs are not exercised and the breeding quality of the yak is reduced. After adulthood, the size of the digestive organs is small, the intake is small, and the digestibility is poor. Inevitably low. The correct course of action is: the forage material is provided after the end of its initial period, and it is first allowed to freely eat hay, and at the same time to train its intake of yak material that meets the nutritional standards. When feed intake reaches more than 0.5 kg per day, it can be weaned. After weaning, the feed intake of refined material will increase rapidly. When it reaches 2 kg, no more yak material will be added, and only green roughage will be added.

Fourth, do not massage the bred breasts

After the first trimester of pregnancy, the breast should be massaged every day to promote its growth and development, and to increase milk production after delivery. And massage the breasts to ensure that the initial fetus can be successfully received milking, to avoid the occurrence of milking.

V. The combination of fine material and supplementary material is unreasonable

Protein feeds generally use only one type. For example, only bean cakes or cottonseed cakes are used. However, soybean cakes, cottonseed cakes, and peanut cakes are rarely used together, and almost no trace element additives are used. It also does not pay attention to the supply of vitamins A, D, and E. The correct approach is to use the special premix or concentrate for dairy cows sold by the regular feed mill and formulate it according to its recommended formula.

Sixth, green rough feed

In the summer and autumn grass season, almost only grass is fed instead of hay and straw, but only straw is fed in winter and spring. The correct approach is to ensure that there is a combination of dry and dry green and dry grass in the four seasons. To do this, we must make silage and dry some of the hay, and also provide a certain amount of roots, tubers and gravels such as carrots. Distillers grains, beer grains, etc.

Seven, cows can't move, they will lose milk in one move.

The majority of households raising dairy cows have no sports grounds. Even if they have a small area, the dairy cows have to leave the country for a long time and lack of exercise. This affects the health of dairy cows, and reduces milk production and quality. In order to ensure the amount of exercise for cows, it is best to insist on driving or grazing for 2-3 hours a day.

Eight, do not brush cattle body, do not repair hoof

In order to promote the skin metabolism of dairy cows and improve milk production performance, milking cows must be brushed 2-3 times a day, preferably before each milking. Due to the effects of nutrition and environmental factors, many dairy cows have deformed hoofs and hoof rots, affecting the normal movement of milk cows and improving the milk production performance. Therefore, hoofs and hoof repairs are performed every spring and autumn.

Nine, inadequate scrubbing when milking, no massage breast, no medicine bath nipple

According to the correct operation procedure, wash the breast with 40-50°C warm water before milking, then rub the entire breast with both hands from top to bottom, wait for the breast to inflate, milk immediately after reflection, and do not stretch when milking. Teat milk. After milking, soaking the teat with liquid medicine, commonly used drugs include 3%-5% sodium hyponitrite and 0.1% benzalkonium chloride.

Ten, not deworming

The surface parasites make the cattle uncomfortable, uncomfortable, walling, grinding piles and increasing nutrient consumption. Therefore, it is necessary to periodically repel insects (including both in vivo and in vitro) in the spring and autumn each year to give full play to the potential of feed, ensure the health of cattle, and increase milk production.
