Yak feed additive for improving yak survival rate and preparation method thereof

Abstract

The invention provides a yak feed additive for improving yak survival rate and a preparation method thereof. The yak feed additive is prepared from a traditional Chinese medicine extract, whey proteinpowder and a compound microbial fermentation broth with a weight ratio of 15-35:45-55:10-30, the raw materials of traditional Chinese medicine extract are 20 to 35 parts of Codonopsis pilosula, 15 to30 parts of Radix Astragali, 10 to 25 parts of sea buckthorn, 10 to 15 parts of Cortex moutan, 10 to 15 parts of Chinese magnoliavine, 5 to 10 parts of Radix isatidis, and 5 to 10 parts of licorice,and the zymophyte in the composite microbial fermentation broth include saccharomycetes, lactobacillus, bacillus, and Clostridium dibutyrate. The Chinese herbal medicine is natural green, safe and non-polluting, and promotes the growth and development of poultry, enhances disease resistance and enhances reproductive function; the microorganisms can improve the nutrient composition of a feed, promotes the absorption of nutrients by yak, and improves the utilization of the feed. The microorganisms can also change the medicinal properties, improves the efficacy, and reduces toxic side effects. The feed additive of the invention has the effects of enhancing resistance, promoting growth and preventing diseases, and improves the survival rate of the yak.

Description

technical field [0001] The invention relates to the technical field of feed, in particular to a yak feed additive capable of improving the survival rate of yaks and a preparation method thereof. Background technique [0002] Yak is one of the unique and rare cattle species that is centered on the Qinghai-Tibet Plateau in China and adjacent to the alpine and subalpine alpine regions. With the progress of society and the development of production technology, yak breeding is also developing rapidly. In addition to pasture grazing and breeding In addition, the combination of captive breeding can also be adopted. Artificial breeding yak just cannot avoid to carry out feed feeding, and existing yak feed mainly contains green fodder, succulent fodder, rough fodder and concentrate fodder.

[0003] In the prior art, in order to ensure the healthy growth of livestock and reduce the sickness of livestock, people add antibiotics to the feed. Although this practice can reduce the incidence of livestock diseases, the use of a large number of antibiotics will lead to low quality of livestock, and Antibiotic Residues Can Harm People Who Eat Livestock Meat
