Feed additives for improving reproductive performance of breeding fur-bearing animals

Abstract

The invention discloses feed additives for improving the reproductive performance of breeding fur-bearing animals. The feed additives are prepared from composite Chinese herbal medicine extracts, pine needle meal, arginine, tocopheryl acetate, beta-carotene, biotin, folic acid, soy isoflavone, dihydropyridine, vitamin C, selenium yeast, organic chromium, oligosaccharides, biological active peptide, non-starch polysaccharide enzyme, amino acid chelated microelements and microecologics, wherein composite Chinese herbal medicine is prepared from epimedium brevicornu maxim, gynostemma pentaphylla, semen cuscutae, eucommia ulmoides, mulberry, polygonum multiflorum, radix rehmanniae preparata, astragali complanati semen, fructus liquidambaris and radix glycyrrhizae. By scientifically preparing composite Chinese herbal medicine extracts and various raw materials, the synergic effect of 1+1>2 is achieved, the product effect is remarkable, the reproductive performance of breeding fur-bearing animals such as minks, foxes and raccoon dogs can be remarkably improved, use is safe and convenient, drug residues, drug resistance and other problems do not exist, and wide market prospects are achieved.

Description

technical field [0001] The invention relates to a preparation method of a feed additive for fur animals, in particular to a feed additive capable of improving the reproductive performance of fur animals such as mink, fox and raccoon dogs, belonging to the field of feed additives. Background technique [0002] The fur animal breeding industry originated abroad. It refers to the industry of artificially raising and breeding fur economic animals such as mink, fox, and raccoon dog, and obtaining their fur and other animal products (mainly providing raw materials for fur clothing and apparel production). It has the characteristics of high benefit and easy breeding, and is a special breeding industry with high added value. my country's fur animal breeding began in 1956. Although it started late, it has developed rapidly. At present, the breeding volume has surpassed Finland, Denmark, the United States and other major breeding countries, accounting for 50% of the world's total bree...

Problems solved by technology

There are few domestic and foreign research reports on the influence of important nutrients in the diet on the reproductive performance of fur animals, which leads farmers to one-sidedly increase or decrease some nutrients in the process of breeding fur animals, which increases production costs unnecessarily and causes feed waste , affecting farmers’ income; therefore, the research and development of feed additives that can improve the reproductive performance of breeding fur animals has become a top priority in promoting the intensive and sustainable development of fur animals such as minks, foxes, and raccoons
