Problems solved by technology

The existing technology is mainly to add rumen fat to increase the energy concentration of the diet; add rumen buffer to prevent rumen acidosis caused by the reduction of roughage intake of dairy cows and overeating of concentrate; add Chinese herbal medicine additives; increase the concentration of electrolytes in the diet; Vitamins, trace element additives, etc. are used, but most of the reported technologies are limited to a single nutrient regulation technology. For dairy cows, the use of a single nutrient regulation technology to solve the heat stress problem of dairy cows is often ineffective (increased milk production of dairy cows) range is below 2.30kg) or has no effect on milk production

Abstract

A feed additive for relaxing the hot stress reaction of milk cow in the summer is prepared from organochromium, cultured yeast, nicotinic acid, VA, VD, VE, sodium selenite (or yeast selenium), copper sulfate, zinc sulfate, cobalt sulfate, calcium iodate, manganese sulfate, etc.

Description

technical field [0001] The invention relates to a feed additive for dairy cows, in particular to a relieving agent specially used for relieving the heat stress response of dairy cows in summer high temperature season, as well as its preparation method and application. Background technique [0002] As we all know, like most countries in the world, most of the dairy cows raised in China are Holstein cattle. Holstein cows are relatively resistant to cold and heat, and their more suitable ambient temperature is 10-16°C. When the temperature rises above 23°C (relative humidity is 80%), this breed of cows will experience a decrease in feed intake and milk production. Heat stress symptoms such as reproductive dysfunction and the deterioration of the health of dairy cows lead to a series of health problems such as ruminal acidosis, ketosis, and retained placenta. [0003] There have been many researches on how to alleviate the heat stress of dairy cows through nutritional regulatio...
