Problems solved by technology

Breeding heat-resistant strains of dairy cows takes a long time and is difficult; improving roof insulation performance and increasing ventilation will increase the construction cost of the cowshed, and it cannot alleviate the long-term high temperature heat stress. Heat stress in dairy cows, but increased lameness in dairy cows
At present, the research on nutritional regulation of heat stress mainly adopts the method of increasing the energy (such as supplemented with rumen fat), protein level and K + content, but the effect is not very obvious in production

Abstract

The present invention discloses a heat stress resistant premix for dairy cow. The premix comprises the following components by weight: 15.0-25.0 parts of an alkaline cation Immunoenhancer, 2.5-5.0 parts of a complex enzyme, 1.0-2.5 parts of coated betaine, 12.5-25 parts of potassium chloride, 12.5-25.0 parts of magnesium oxide, 2.5-3.5 parts of vitamin premix for dairy cow, a 5.0-6.0 parts of trace element premix for dairy cow and 10.0-49.0 parts of a carrier. The premix has the effects of supplementing alkali cation, potassium, magnesium, active methyl and exogenous enzymes, regulates osmotic pressure and relieves heat stress generated by summer heat in dairy cow, promotes lactation, improves milk components, improves immunity and helps to improve health and milk quality of the dairy cow.

Description

technical field [0001] The invention relates to the technical field of animal feed, in particular to a heat stress-resistant dairy cow compound premix. Background technique [0002] Heat stress in dairy cows is a non-specific response of dairy cows to a high temperature environment that is unfavorable to their physiology. The normal body temperature of dairy cows is 38.5°C, and the moderate feeding environment temperature is 10°C to 20°C. When the ambient temperature exceeds 25°C, a stress response will occur. Heat stress seriously affects the feed intake of dairy cows. According to relevant reports, dairy cows at ambient temperature The feed intake starts to decrease at 22°C to 25°C, and the feed intake decreases significantly at 25°C and above. At 26°C, the feed intake will not exceed the normal 60 portions, and the cows with poor heat resistance will stop at 40°C. Feed intake and heat stress can also reduce the production of immunoglobulin in dairy cows and reduce the ...
