Abstract

The invention discloses a preparation method and application of a cassava waste active feed raw material. In the cassava waste active feed raw material prepared by continuous fermentation of fresh cassava waste by bacillus subtilis and candida utilis, the nutritional ingredients mainly include: 15.0-20.0% of crude protein, 10.0-13.0% of amino acids, 2.5-3.5% of crude fat, 7.0-10.0% of crude fiber, 0.5-2.0% of oligosaccharides and 2.0*10<3>-5.0*10<4> CFU / g of living bacteria count. In the invention, by feeding a sow with a reasonable combination of cassava waste active feed raw material and silkworm chrysalis meal and the like, the constipation rate and disease-induced loss of the sow can be reduced in an intensive farming environment, and higher benefits are created for farmers. In the invention, the production process of the bioactive feed raw material is safe and pollution-free, and the feed production cost can be reduced by 15.0-25.0%; and meanwhile, the benefits of the cassava industry chain are increased, and the industrial application prospect is perfect.

Description

technical field [0001] The invention relates to the technical field of feed preparation, in particular to a preparation method and application of cassava residue active feed raw materials. Background technique [0002] In the modern pig industry, sow constipation is an important problem that plagues the majority of farmers. Sows not only need to maintain basic nutritional needs, but also need to prepare for pregnancy, production and lactation. Constipation is not only related to their own health, but also affects the health of sows. Production performance, piglet survival and growth performance. In intensive farming, the constipation rate of sows is 20% to 35%, and some are as high as 60%. Pregnant sows are more common, which is a key point that limits the benefits of farmers. The specific manifestations of sow constipation are: poor defecation, mild constipation causes toxins to accumulate in the body, bacterial flora multiplies, body immunity decreases, pregnant sows do n...
