Raise the Sheweng Winter In the winter, keep the doors and windows of the cowshed on the west and in the north, and seal the walls tightly to prevent the thieves from invading. The doors and windows on the sunny side should be hung.
Raising feed standards The energy produced by the winter cows' body is diverted to maintain body temperature, and the cow's nutrition should be increased accordingly, generally 10% to 15% higher than the standard for feeding, ie 15% more mixed concentrate.
Drinking warm water in winter cows eat more hay, 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. The suitable temperature for drinking water is: 12 to 14°C for cows, 15 to 16°C for dairy cows, and 35 to 38°C for calves. According to reports, drinking milk at 8.5°C in winter cows is about 8% higher than drinking water at 1.5°C.
Topping up salt is one of the main components of gastric juice. The secretion of gastric juice from cows in winter increased, and the demand for salt increased accordingly. The daily supply of salt depends on the weight of the cow and the amount of milk produced. The daily supply is usually 50 to 100 grams. In addition to mixing 1% of dietary concentrate, a salt tank can also be set up to allow cattle to feed freely.
Insufficient lighting in winter cowhouses, lack of fresh air, and lack of exercise for dairy cows can lead to decreased milk production and some diseases. Before and after noon every day, you should drive it out of the house for sunbathing and fresh air.
Do a good job of brushing the body of cattle 2 to 3 times a day to keep the body clean. Keep the pens clean and dry, where the cows lie on soft grass, and wet places often sprinkle some grass ash, which can sterilize and prevent disease, and can absorb moisture and deodorize. Cows are dewormed once in winter and immunized.
Winter to improve milk production management
The optimum temperature for dairy cows is 8°C～16°C, and the temperature in winter is below 0°C. If the feeding and management are poor, the milk production of dairy cows will decrease.
