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 starter, there are many types of strains required, and many auxiliary materials are added, especially a variety of expensive enzyme preparations. The operation is complicated and the energy consumption 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 production cycle is long, the energy consumption is large, and it is difficult to realize industrial production

Abstract

The invention mainly relates to a method for preparing a protein feed by fermentation on straw and cake using aerobic mixed bacteria. The method for preparing a protein feed by fermentation on straw and cake using aerobic mixed bacteria is mainly characterized by comprising the following steps of: uniformly stirring straw, cake, wheat bran and corn flour, and enabling the water content thereof toachieve 50-60%; adding ammonium sulphate having an amount of 0.5-4% relative to the total amount of dry materials and urea having an amount of 0.5-3% relative to the total amount of dry materials; adjusting pH to 5.5-6.5 by 1% lime water; joining the raw materials in bacterial solution having an amount of 8-12% relative to the total amount of dry materials, obtained by mixing geotrichum candidum,lactic acid bacteria and bacillus licheniformis, and having a ratio by weight of 50-60% of geotrichum candidum to 30-35% of lactic acid bacteria to 5-10% of bacillus licheniformis; and fermenting for18-24 hours in a ventilation condition at a temperature of 28-32 DEG C, so as to prepare the fermented protein feed. The method for preparing a protein feed by fermentation on straw and cake using aerobic mixed bacteria disclosed by the invention utilizes modern bio-technology, optimizes the best combined bacteria, has simple and convenient production process, saves equipments and energies, and reduces the needed investment.

Description

technical field [0001] The invention mainly relates to a method for preparing protein feed by fermenting straw cake with aerobic mixed bacteria. 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 feed industry to vigorously develop protein feed with high nutritional value and low production cost. my country's agricultural product waste such as straw, cake and other raw material resources are quite rich, and 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 production, and the main problems are: [0003] The traditional anaerobic ferment...
