Chinese herbal medicine feedstuff additive-summer quiet powder and preparation method as well as application thereof

Abstract

The invention discloses a Chinese traditional herbal medicine foodstuff additive, Xia'ansan, and a preparation method and applications thereof. The additive is made from astragalus root, Chinese angilica, tube of dwarf lilyturf, dried tangerine peel, green tangerine peel, vegetable sponge, dandelion, fructus forsythiae, radix bupleuri, honeysuckle vine, complete Trichosanthes kirilowii Maxim, Saponaria vaccaria, fructus liquidambaris, and liquorice. The preparation method of the invention is that: the 14 materials are air-cured and dried, dried at 60 DEG C, and then crushed and sifted by 100-mesh sifter, and finally subpackaged. The additive can be blended into the foodstuff for feeding cow, which has heat and stress resistance function to cows giving milk, thus enhancing milk yield. The additive can be used in a hot season for 30 to 45 days in a dosage of 150 to 200g per day for one cow, which can ensure that cow maintains a milk yield increased by more than 10% in 120 days, and can dramatically reduce the incidences of mastitis, endometritis and hoof disease.

Description

Technical field: [0001] The invention relates to a feed additive, in particular to a feed additive made from Chinese herbal medicines, a preparation method and application thereof. Background technique: [0002] Chinese Holstein cattle are resistant to cold and heat. The optimum temperature for lactation is 10-21°C. The upper limit of the production environment temperature is 27°C, and the relative humidity does not exceed 75%. If the humidity exceeds the range, it will affect the evaporative heat dissipation of the cows. If it exceeds the appropriate temperature range, it will have an adverse effect on the cows. If it exceeds the production environment temperature limit, the milk production will decrease significantly. When the temperature rises to 35°C, the average milk production drops by 37.4%, the cows breathe faster, sweat more, drink more water, feed intake decreases, and the incidence of mastitis and hoof disease rises. The more high-yielding cows are subjected to he...

Problems solved by technology

With global warming, summer lasts for 116-140 days, the ambient temperature exceeds 22 degrees Celsius, and the temperature and humidity index (THI) is above 72. Dairy cows are in a state of heat stress for a long time, and the milk production drops sharply, causing major damage. Economic loss with dire consequences for cow production and health
