Straw feedstuff and its preparation method

A technology of straw feed and straw, which is applied in the field of straw feed and its preparation, can solve the problems that the nutrients required for growth cannot be satisfied, the growth and development of livestock cannot be satisfied, and the nutritional value of straw is low, so as to achieve high practical application value and eliminate Anti-nutrition and many restrictive factors, the effect of simple and easy preparation method

Problems solved by technology

However, there are also many limiting factors in simply using straw as feed: 1) low nutritional value, the content of nutrients such as calcium, phosphorus, vitamins and crude protein in straw is extremely low, but the content of silicate is high; 2) it is not easy to digest , the crystalline structure formed between the epidermal membrane, waxy layer, cuticle of the stem epidermis, silicon cells, and a large amount of lignin and cellulose contained in the straw all set obstacles to the utilization of straw.
Therefore, straw can only satisfy the hunger of domestic animals, and the nutrients required for their growth cannot be satisfied.
[0003] Studies have shown that using the "feed compound enzyme" preparation containing cellulase, ligninase, amylase, glucoamylase, pectinase and other digestive enzymes to decompose the epidermal membrane, waxy layer, and cuticle of the stem epidermis in the straw It can improve the absorption and utilization of nutrients in straw by livestock, but because of the low nutritional value of straw itself, using it alone as feed still cannot meet the needs of livestock growth and development.

Abstract

A straw-stalk feed with high bioactivity and nutritive value and low cost is prepared through preparing the culture medium from chicken droppings, straw and stalk, adding the composite enzyme for feed, adding useful bacteria chosen from trichoderma, blue mold and candida, and fermenting culture.

Description

technical field [0001] The invention relates to a feed and a preparation method thereof, in particular to a straw feed and a preparation method thereof. Background technique [0002] Straw resources have the characteristics of many types, wide distribution, and few competitive uses, so the potential for development and utilization is huge. However, there are also many limiting factors in simply using straw as feed: 1) low nutritional value, the content of nutrients such as calcium, phosphorus, vitamins and crude protein in straw is extremely low, but the content of silicate is high; 2) it is not easy to digest , the crystalline structure formed between the epidermal membrane, waxy layer, cuticle of the stem epidermis, silicon cells, and a large amount of lignin and cellulose molecules contained in the straw all set obstacles to the utilization of straw. Therefore, stalks can only satisfy the hunger of domestic animals, and the nutrients required for their growth cannot be s...
