Feed adopting bean dregs as raw material and being fermented by floor heat and preparation method thereof

Abstract

The invention relates to feed and a preparation method thereof. Bean dregs are adopted as main raw materials, then soybean meal, sweet potato starch, wheat bran, yeast, vitality 99 ferment agent, coarse feed degrading agent, calcium hydrophosphate and the like are added into the bean dregs to be blended and mixed and be fermented through the floor heat so as to obtain the feed. The feed produced through the above method can increase the appetite of the animals, can improve the immunity of the animals and can improve the farrowing rate of sows.

Description

technical field [0001] The invention relates to the technical field of feed, in particular to a fermented feed prepared by using bean dregs as a raw material, adding biological probiotics and enzyme preparations, and fermenting with geothermal heat, and a preparation method thereof. Background technique [0002] The nutritional components of bean curd dregs were determined by the national standard method, and the results showed that the contents of insoluble dietary fiber, crude fiber, protein, crude fat, reducing sugar, total sugar, ash, and flavonoids in bean curd dregs were 36.29%, 9.62%, and 17.84%, 5.90%, 2.57%, 37.40%, 3.85%, and 0.22%. The content of mineral elements potassium, calcium, sodium, magnesium, zinc, iron, copper, chromium and manganese in bean curd residue are 9.36mg / g, 4.19mg / g, 0.96mg / g, 2.57mg / g, 0.026mg / g respectively , 0.11mg / g, 0.0067mg / g, 0.0018mg / g and 0.019mg / g. Tofu dregs have the nutritional characteristics of high fiber, high protein, low fat...

Problems solved by technology

[0003] The traditional method of utilization is to use bean dregs as animal feed and directly feed them to animals, because bean dregs contain anti-trypsin, saponin, hemagglutinin and other anti-nutritional factors, among which trypsin inhibitors can hinder the action of trypsin in pigs on beans. Digestion and absorption of protein, causing diarrhea, affecting growth, poor palatability, difficult to digest, and low feed utilization

This is not only a great loss economically, but also a great waste of precious resources
