In order to increase the milk production of dairy cows, it is an extremely important technical measure to feed the cows with succulent feed. Practice has proved that this type of feed has good palatability and high digestibility and is an important feed for increasing the milk production of dairy cows.
Beet sugar beet dry matter contained 5% to 6% sugar, 1% to 2% protein, 1.7% crude fiber, and 9% nitrogen-free extracts. When feeding, they should be washed and chopped first. Each cow can feed 30-40 kg per day. The beet feed should not be allowed to stand for too long, so as to avoid nitrate poisoning caused by dairy cows.
Fresh beet pulp residue contains 90% water, crude protein 0.9%, crude fat 0.1%, crude fiber 2.6%, nitrogen-free extract 3.5%, but no carotene and vitamin D. Feeding of sugar beet slag can provide the cow with necessary fillers. Sugar beet residue can feed 3 to 5 kilograms per cow per day.
The average potato-containing potato dry matter content was 22%, crude protein 1.6%, crude fat 0.1%, crude fiber 0.7%, and nitrogen-free extract 18.7%. Each 3.5 to 4 kilograms of potatoes is equivalent to 1 kilogram of cereals, and about 80% of the dry matter is starch, easy to digest, but the lack of methionine, calcium, phosphorus and carotene, etc., is a typical carbohydrate-rich material containing more water, but also One of the main energy sources for dairy cows.

When stored, it is best to use wet sand to prevent rot and nutrient depletion.
Fruits and vegetables are mainly pumpkin, watermelon rind and melon skin. This kind of feed has the most moisture content. For example, the pumpkin has a moisture content of 90% to 95% and dry matter of about 10%, wherein crude protein is 1%, crude fat is 0.3%, crude fiber is 1.2%, and nitrogen-free extract is 6.8%. This kind of feed has more soluble sugar and starch, and contains a lot of carotene. When feeding, they should be washed and shredded first, and 15-20 kg per cow per day.
