Technical Field

The invention relates to the technical field of cow feed preparation, in particular to a feed for improving milk fat metabolism of a cow and a preparation method thereof.

Background

The dairy cattle is a dairy cattle, and is a good variety bred and bred highly, the dairy cattle in China mainly comprises black and white cattle, the variety is introduced from cattle and sheep breeding bases of the livestock bureau of Shandong province in 1980, and the variety has strong adaptability, wide distribution range, high milk yield and coarse feeding resistance. The black and white cow is also called Chinese Holstein cow, which has a history of more than one hundred years and has a very complicated breeding process. In a word, the high-generation hybrid is obtained by breeding high-generation hybrid seeds of pure Dutch cattle and local cows for a long time. The milk has comprehensive nutrition, is a beverage suitable for long-term drinking, and is also an important raw material in the modern dairy industry.

The skin of the milk cow is thick, and the heat dissipation is difficult, so that the milk cow belongs to cold-resistant and heat-intolerant animals, and the production performance of the milk cow in the environment of 4-18 ℃ is best. In hot summer, the temperature often reaches or exceeds 30 ℃, the duration is long, if the feeding management is not good, the dairy cows can generate a series of heat stress reactions, so that the body temperature of the dairy cows is increased, the respiration is accelerated, the appetite is reduced, the reproduction rate is reduced, and even the dairy cows die. When the summer comes, if the mouth of the cow breathes rapidly (the breathing frequency exceeds 80 times/minute), the tongue extends outwards, the saliva secretion is excessive, the cow has no diseases and the body temperature rises, which indicates that the cow is in a heat stress state, effective measures should be taken in time to reduce the heat stress of the cow, and therefore, a feed for improving the milk fat metabolism of the cow is urgently needed, so that the milk production rate and the milk quality of the cow are improved.
