Embodiment Construction

[0019] A method for preparing extruded fermented feed from fermentation bed waste, comprising the following specific steps:

[0020] (1) Liquid fermentation culture:

[0021] After breaking up the waste material of the fermentation bed used for livestock and poultry breeding, it is set aside; take 30 parts of the waste material of the fermentation bed and put it into 100 parts of water in a container, put 3 parts of urea and 0.5 part of salt into the water and stir evenly, and inoculate and activate the urea candida Yeast strains were cultured at 30°C and 150r / min for 4 days to obtain a fermentation broth;

[0022] (2) Curing treatment:

[0023] According to the parts by weight, mix 800 parts of stalks pre-crushed to a length of 2-3 cm, 300 parts of fermentation bed waste, 60 parts of lime, and 8 parts of salt, and then add 1500 parts of water for aging, and fully mix once every 2 hours , take it out after 8 hours, and finally add 300 parts of fermentation bed waste to it, a...

Abstract

The invention discloses a method for preparing puffed fermented feed from fermentation bed wastes. The method comprises the following steps: with livestock breeding fermentation bed wastes as a fermentation medium, inoculating yeast bacteria, and performing fermentation so as to prepare fermentation broth; performing high-temperature curing and extrusion puffing treatment on raw materials such asthe fermentation bed wastes and straw, and performing primary degradation on the raw materials. The effects of soft textures and fragrant smell are achieved, a next step of fermentation is facilitated, the fermentation time is shortened, harmful bacteria in the raw materials are thoroughly killed and damaged at a high temperature and high pressure, and the quality of the feed is improved; and through mixed fermentation of puffed and cured materials and the fermentation bed wastes, the materials are further degraded, proliferation of harmful bacteria and putrefying bacteria is inhibited, the feed value is increased, decaying is not easily caused, the feed can be stored and applied to livestock for a long time, and when animals are fed with the feed, not only are the absorption rate and theimmunity of the animals improved, but also intestinal diseases of the animals are reduced.

Description

technical field [0001] The invention relates to the technical field of fermented feed, in particular to a method for preparing puffed fermented feed from fermentation bed waste. Background technique [0002] The main raw materials for the litter of livestock and poultry in the fermentation bed are sawdust and chaff. After 1-3 years of breeding livestock and poultry, about 10-30% of the fiber in the raw material is decomposed, and most of the remaining fiber is excreted. The feces and urine and some metabolites are more or less polluted and toxic. Since these wastes are not reused or treated, they are discarded at will in the breeding area, which not only invades land resources, but also causes serious pollution to the rural environment, which directly affects the healthy development of fermentation bed farming to solve the problem of breeding sewage and the construction of new countryside. Contents of the invention [0003] The invention provides a method for preparin...
