Technical Field

The invention relates to the technical field of dairy cattle feeding, in particular to a premix for improving the production performance of dairy cattle in the lactation period.

Background

The milk contains rich nutrient substances such as protein, fat, vitamins, mineral substances and the like, and the milk protein contains amino acid necessary for human bodies; milk fat is mostly short-chain and medium-chain fatty acid, and is easily absorbed by human body; the mineral substances such as potassium, phosphorus, calcium and the like are reasonable in proportion and easy to absorb by human bodies.

The nutrient substances required by the dairy cows for maintaining life, growing and developing, producing milk and breeding offspring comprise moisture, energy, protein, mineral elements, vitamins and the like. Besides part of water, the nutrition required by the dairy cow needs to be provided by the feed. According to the digestive physiology of ruminants, the daily ration of the dairy cattle needs to have enough cellulose, and the quantity and the proportion of the neutral detergent fiber and the acidic detergent fiber contained in the daily ration of the dairy cattle meet the requirement of the dairy cattle for maintaining normal digestive function as far as possible. Cellulose is mainly derived from roughage, however, most roughage has relatively low energy, protein, mineral elements and vitamins, and cannot meet the requirements of growth, milk production and breeding offspring of dairy cows, particularly the milk production requirements of high-yield dairy cows. In order to exert the milk production potential and improve the breeding benefit of the dairy cows, a certain amount of feed premix is added into the daily ration of the dairy cows on the basis of coarse feed to supplement the deficiencies of energy, protein, mineral elements and vitamins.
