How to increase milk production in dairy cows in winter?

For cows, the optimum temperature is 8 °C ~ 16 °C. In most parts of northern China, winter temperatures are below 0°C, coupled with poor feeding and management, milk production will be affected. The measures to change this effect are as follows: 1. It is generally 8°C~16°C to increase the suitable ambient temperature for the cows in the Sherwin Cow. In this range, the cow's metabolic rate and heat production are at the lowest level. The performance is: low feed consumption and low incidence. If the temperature of the barn is below 0°C, the cattle will emit a lot of energy to maintain body temperature. Therefore, it is particularly important to keep the appropriate temperature of the cows in the cold winter. The doors and windows and wall joints on the west and the north side of the cowshed should be blocked tightly to prevent thieves from invading; the doors and windows on the sunny side should be hung. Second, improve the feed standard Rumen fermentation of dairy cows and the energy generated by it is transferred to maintain body temperature up, the cows to maintain and produce nutrition also increased accordingly, generally 10% to 15% higher than the feeding standard. Therefore, it is necessary to increase 15% of the mixed concentrate in the winter so as to maintain or increase milk production. Third, drink plenty of warm water in winter cows eat more hay, increased secretion of digestive juice, only saliva secretion of about 50 liters per day, if not enough water, appetite will drop, resulting in reduced milk production, and even disease. Cows need about 5 kilograms of water for every 1 kilogram of dried feed. Therefore, the total amount of drinking water can not be less than summer. According to reports, drinking milk at 8.5°C in winter cows is about 8% higher than drinking water at 1.5°C. However, drinking milk at 20°C for a long time will weaken the body and reduce the digestive capacity of the stomach. The suitable temperature for dairy cows to drink in winter is: 12°C~14°C for cows, 15°C~16°C for dairy cows and pregnant cows, and 35°C~38°C for calves. Fourth, to make up for salt Salt is one of the main components of gastric juice. As the secretion of gastric juice from cows increases in winter, the demand for salt also increases. If the salt intake is insufficient, the appetite of dairy cows will decrease and the milk production will decline. The daily supply of salt should be determined by the size of the cow's body weight and the amount of milk produced, and it is usually 50 to 100 grams per day. In addition to mixing 1% of dietary concentrate, a salt tank can also be set up to allow cattle to feed freely. Fifth, to strengthen the sports cows in the winter long-term support in the lack of light, the air is not fresh in the house, can not get exercise. This will not only reduce milk production, but also lead to some diseases. Generally, they are driven out of their homes before and after noon every day for sunbathing and breathing fresh air. At the same time, they should brush their bodies 2 or 3 times a day to keep the body surface clean, promote blood circulation, increase the ability to resist disease and cold, and increase production. Milk volume. Sixth, do a good job in maintaining a clean and dry sanitation, dairy cow lying in the place, it is best to add soft grass. In damp places, weeds should be regularly sprinkled with ash, which can sterilize and prevent disease as well as absorb moisture and deodorize. In the winter, cows should be dewormed once, and immunizations must be prepared to prevent the occurrence of infectious diseases.
