For cows, the optimum temperature is 8-16°C. The winter temperature in our province is mostly below 0°C. Coupled with poor feeding and management, the milk production of dairy cows will be affected. The measures to change this effect are as follows: Raise the Sherwin's temperature: The suitable ambient temperature for dairy cows is generally 8-16°C. 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. Raising feed standards: The rumen fermentation of dairy cows and the energy generated by them are transferred to maintain body temperature, and the nutrition that cows maintain and produce also increases accordingly, generally 10% to 15% higher than the standard for feeding. Therefore, it is necessary to increase 15% of the mixed concentrate in the winter so as to maintain or increase milk production. Drink plenty of warm water: In winter, cows eat more hay, and the secretion of digestive juice increases. Only saliva will secrete about 50 liters per day. If you can not fully drink water, appetite will drop, resulting in decreased milk production, or 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 drinking temperature for dairy cows in winter is: 12-14°C for cows, 15-16°C for dairy cows and pregnant cows, and 35-38°C for calves. 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, generally 50-100 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. Strengthen exercise: Dairy cows stay in the house for a long period of time in the absence of light and air. They do not get exercise. This will not only reduce milk production, but also lead to some diseases. Usually, they are driven out of their homes before and after noon everyday for sunbathing and breathing fresh air. At the same time, the body should be brushed 2-3 times a day to keep the body surface clean, promote blood circulation, increase resistance to disease and cold, and increase production. Milk volume. Do a good job of hygiene: Keep the pens clean and dry. Place the cows where they are lying, preferably with 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.
