What problems should be paid attention to in raising dairy cows in winter?

Dairy cow is a dairy breed of yellow cattle. After a high degree of breeding and breeding, the milk produced by dairy cows is nutritious and suitable for long-term drinking, and it is also an important raw material for modern dairy industry. Dairy cows in China are mainly black and white dairy cows. It is a high-generation hybrid between purebred Dutch cattle and local cows. After long-term breeding, what problems should be paid attention to in raising dairy cows in winter?

I. the problem of drinking water

An appropriate amount of drinking water is the key to improve milk production. The temperature in winter is too low, the water is easy to freeze, which is not conducive to drinking, and dairy cows are prone to drinking water problems, so it is necessary to do a good job in drinking water management in winter, maintain all-day water supply, and appropriately increase the temperature of water. The temperature is kept at 10-15 degrees, and the water temperature is too high or too low, which will affect the growth of dairy cows and thus affect the milk yield.

II. Feed problem

When the temperature is low in winter, cows need to emit more heat in order to maintain their body temperature, so they also need to consume more nutrition, so in winter, it is necessary to properly adjust the feed ratio of cows and increase the ratio of nutrition to energy in feed. to improve the appetite and food intake of dairy cows, it is necessary to meet the nutritional needs of dairy cows in winter in order to ensure the normal growth of dairy cows.

III. Nutrition

In winter feed, it is not only necessary to increase the proportion of energy, but also to increase the amount of trace elements such as calcium and phosphorus. If cows lack trace elements, it will affect the growth and development of cows, such as osteomalacia, such as osteomalacia, etc., especially for cows, the lack of trace elements will affect milk yield, bone hyperplasia, limb deformation and other problems. In addition, it is necessary to increase the content of minerals in the feed to ensure the normal growth of the reserve cattle.

IV. Reproduction

Mating and breeding of dairy cows in winter is better, because the temperature in summer is high, which is not conducive to the growth of calves, and it is easier to manage calves in winter than in summer, so we should do a good job in cow reproduction in winter to promote the conception of cows. improve the efficiency of breeding, provide sufficient quantity for breeding in the coming year, reduce breeding costs, and at the same time, do a good job in fetal protection, do not feed deteriorated feed and frozen water. In order to prevent abortion caused by the fall of pregnant cattle, we should also pay attention to meet the nutritional needs of pregnant cattle and strengthen management.

V. the problem of preventing cold and keeping warm

The barn should do a good job of preventing cold and keeping warm in winter, reduce the heat dissipation capacity of the barn, block most of the vents in time, prevent the cold wind from invading, close the tuyere at the top of the barn in time, and properly add bedding and hay in the barn to prevent cows from lying on the cold ground, belly catching cold, affecting the growth of cows, and regularly clearing out the manure and residual feed in the barn to prevent the barn from getting wet. Be properly ventilated if necessary.

The above is a brief introduction to the main technical points of cow feeding and management in winter by Tuliu. the management of dairy cows in winter is very important, which is directly related to the survival and milk production of dairy cows, and is linked to the economic benefits of farmers, so we must pay attention to it.
