I don't know if you have paid attention to the recent artificial milk hotspots. Some netizens said that artificial milk will have a strong impact on traditional dairy farming. Of course, some people disagree. As the main force in the production of dairy products, dairy farming has a long history and experience, and the fresh milk produced by it must be irreplaceable for artificial milk. So many farmers who raise dairy cows will ask, why is the milk production of dairy cows in cold weather such as winter weather? The following is a key point to improve the milk production of dairy cows in winter. How to increase the milk yield of dairy cows in winter? 1. Improve feed standards Feed standards for winter feeding are generally 10% to 15% higher than during the warm season, especially for concentrates. 2, increase the lighting time In winter, the temperature is low and the lighting time is insufficient. Properly increasing the light time can not only increase the yield milk (about 10%), but also increase the temperature of the barn. Artificial lighting can be used, for example, using white fluorescent lamps, which are illuminated for 16 to 18 hours a day. 3. Guarantee drinking water and sports Drinking water should not only strictly follow the breeding standards, but also need to properly raise the drinking water temperature in winter. The test shows that in the winter, drinking 8.5 °C warm water for the cows will drink about 1.5% of the cold milk. In the warm winter sun that is rare in winter, the cows can be rushed outside the shed for proper exercise, which can effectively increase physical fitness and increase appetite, thereby increasing milk production. 4, wear a cover to protect the breast Wearing a bra on the breast of the cow can help keep warm and cold, clean the breast, improve the milk and milk yield. 5, supplement salt consumption The daily supply of salt depends on the weight of the cow and the amount of milk produced. Generally, 50-100 grams of salt is supplied per head per day. The above are some key tips for improving the milk yield of dairy cows in winter. At the same time, it is necessary to pay attention to the fact that in winter and summer, the sanitary management of the barn should pay extra attention, properly sterilize the barn and clean the cows for the cows. Providing a comfortable living environment is also essential for ensuring an increase in milk production.

For the most common waxy and sweet corn on the market, waxy corn has a higher nutrient content than regular corn, containing 70-75% starch (and almost all straight-chain starch), more than 10% protein, 4-5% fat and 2% multivitamins, with more grains, VA, VB1 and VB2 in protein than rice, with the highest fat and VB2 content. Yellow maize also contains carotenoids, such as rice and wheat. The molecular weight of waxy maize starch is more than 10 times smaller than that of ordinary maize, and the starch makes glutinous rice sticky and soft, softer than ordinary hard maize. It is more than 20% more digestible to eat than regular maize and it is suitable for people with less than perfect teeth. At the same time, it is not suitable for diabetics because of the very high content of straight-chain starch (a polysaccharide).
Waxy maize is also known as sticky maize. The grain has coarse, waxy endosperm, similar to shiny, glassy (clear) grains such as hard and dent maize. Its chemical and physical characteristics are controlled by a recessive gene, which is located on chromosome 9. 100% of the starch in the endosperm is straight-chain starch.
