Problems solved by technology

But what is reported at present is not perfect enough, it is difficult to form industrialized production, and the main problems are:
The disadvantages of this technology are: (1). When preparing anaerobic microbial fermentation agent, there are many kinds of strains required, and many auxiliary materials are added, especially expensive multiple enzyme preparations are added, which is complicated to operate and energy-consuming and investment are relatively large
(2). The production cycle of anaerobic fermentation feed is long, generally takes 7--30 days, the growth and reproduction of bacterial cells is slow, the number of product cells is small, and the protein content is low
(3). The plant area occupied by feed production is large, the energy consumption is large, and it is difficult to carry out industrial production
The disadvantage of this technology is that there are many pretreatment equipment, high energy consumption, and the soluble nutrients are taken away by the dross filtrate that has been removed, and must be recycled or treated.

Abstract

A method for preparing the bacterial protein forage includes such steps as providing distillers' grains, straw or stalk, bran and corn powder, stirring, adding ammonium sulfate and urea, regulating pH=5.5-6.5 by lime milk, inoculating the liquid mixture of reticularia, candida utilis and Rhizopus, and fermenting at 28-32 deg.C for 18-24 hr in the ventilation condition.

Description

Technical field: [0001] The invention mainly relates to a method for producing bacterial protein feed by solid-state fermentation of dregs and straw with aerobic mixed bacterial liquid. Background technique: [0002] Our country has a large population, but there is a serious shortage of protein, and there are certain difficulties in increasing production or importing fish meal, which seriously affects the rapid development of my country's animal husbandry. It is the development trend of the feed industry to vigorously develop feed with high nutritional value and low production cost. my country's food and beverage industry is rich in raw material resources such as waste liquid, waste residue, and agricultural product waste such as straw. The use of these raw materials to produce livestock and poultry feed has become a concern of scientific and technological workers in recent years. But what is reported at present is not perfect enough, it is difficult to form industrialized ...
