Straw microbiological feed

Abstract

The invention relates to a straw feed produced by using a microbiological degradation technology, and aims at providing a straw feed with a good degradation effect and a production method of the straw feed. A microbiological strain solution used in the straw feed comprises 2.0*10<8>pfu / ml of white-rot fungi, 2.0*10<12>pfu / ml of lactobacillus acidophilus, 2.0*10<8>pfu / ml of trichoderma viride, 3.0*10<11>pfu / ml of bacillus subtilis and 5.0*10<12>pfu / ml of candida utilis according to the activity amount. The straw feed comprises the following components in parts by weight of 1.5-2kg of urea, 0.5kg of brown sugar, 0.1-0.2kg of composite trace elements and 0.02-0.06kg of composite vitamins in the terms of 100kg of straws; the microbiological strain solution is prepared according to the proportion that 0.05-0.15L of a substrate is fermented by 100kg of the microbiological strain solution; the urea, the brown sugar, the composite trace elements and the microbiological strain solution are mixed to prepare a feed liquid; the feed liquid is uniformly sprayed on the straws; and the straws are compressed into cube blocks of 50*50*80, and the cube blocks are sealed by using black plastic films, stacked and fermented for 30days to obtain the straw feed. The efficiency of fermenting and degrading straws is remarkably improved; and the fermented plastic is rich in nutritive values, and is beneficial to being digested and absorbed by cattle and sheeps.

Description

technical field [0001] The present invention relates to straw feed produced by microbial degradation technology. Background technique [0002] At present, my country's animal husbandry is developing vigorously, and the problem of feed shortage is prominent, and the contradiction between human and animal competing for food and land is very prominent. my country is a big agricultural country with abundant crop straw resources. Only corn straw can produce about 240 million tons per year. Straw refers to the general term for the stems, leaves and ears of mature crops. Usually refers to the remainder of wheat, rice, corn, potatoes, oilseeds, cotton, sugarcane and other crops after the seeds are harvested. Straw is rich in resources and is the main source of roughage for herbivorous livestock. [0003] However, due to the low content of digestible protein and high crude fiber content of straw, most of the cellulose cannot be decomposed by strong acid and alkali or specific micr...

Problems solved by technology

However, the large-scale fermentation treatment of straw is very different from the small-scale fermentation treatment in the laboratory.
