1, add the baking soda method. From the beginning of the lactation period until the end of the lactation period, 100 grams of baking soda is fed to each cow's diet daily, and milk production can be increased by 25%.

2, add placental powder method. The postpartum placenta of the cows was washed and chopped and soaked in 3%-5% saline, and the cows were fed 200 grams each time, once a day.

3, make up for salt. 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 50-1OO grams. In addition to mixing 1% of dietary concentrate, a salt tank can also be set up to allow cattle to feed freely.

4, add green feed. Appropriate feeding of green and juicy feed can increase milk production. Such as radish, carrots, cabbage, sweet potatoes, potatoes and so on.

5, increase the light. In the 60 days before the cow's lactation, the cow is allowed to receive light 16 hours a day, not limited to receiving natural light, and milk production can increase by 30%.

6, drink enough warm water. In winter, when cows eat more hay, if they can't drink enough water, their appetite will decline, resulting in decreased milk production and even disease. Cows need about 5 kilograms of water for every 1 kilogram of dried feed. The suitable temperature for drinking water is: adult cow 12°C-14°C; milk production, pregnant cow 15°C-6°C; calf 35°C-38°C.

7, Tim feeding kelp method. Add 300-500 grams of chopped kelp to each cow feed daily to feed cows.

8, add night meal. At about 10 o'clock in the evening, the cows are fed proper amounts of fodder, and then they drink enough warm water or congee. The cold-resistance of the cows will be greatly enhanced, and the milk yield will be significantly increased.

9, feed urea method. Cows were fed 10-15 grams of urea per 100 kilograms of body weight.
