A fermentation accelerator for preparing feed from air-dried bagasse

Abstract

The invention discloses a fermentation accelerator using air-dried bagasse to prepare feed. The preparation method is as follows: S1, strain expansion: expand and cultivate Lactobacillus plantarum, Pediococcus lactis, Streptococcus faecalis and Bacillus subtilis respectively; S2, Preparation of lactic acid bacteria fermentation accelerator: after the number of effective viable bacteria in S1 reaches the corresponding number, mix according to volume ratio 1:1:1:3‑5 to make lactic acid bacteria fermentation accelerator bacterial liquid; S3, preparation of fermentation material: use MRS ‑S medium adjusts the moisture content of air-dried bagasse pulverized material to 65‑75%, add 0.5% urea, 1% ammonium sulfate, 8% sucrose in dry weight, stir evenly, and make fermentation material; S4, anaerobic fermentation: mix The lactic acid bacteria fermentation accelerator bacterial liquid in S2 is evenly sprayed on the fermentation material in S3 at a concentration ratio of 10%, and the fermentation accelerator for the required feed can be obtained by solid-state anaerobic fermentation at 33-37°C for 20-25 days.

Description

technical field [0001] The invention relates to a ruminant feed, in particular to a fermentation accelerator for preparing feed by using air-dried bagasse. Background technique [0002] As an important part of agriculture, animal husbandry is of great significance to strengthening the scientific and technological innovation of animal husbandry and promoting the transformation and application of scientific and technological achievements. my country is the world's largest producer of sugarcane, with an annual output of 70 million tons of sugarcane, ranking third in the world after Brazil and India. Bagasse is a by-product of the sugar industry. It is the solid waste residue left after the sugarcane is squeezed to extract juice. Generally speaking, 1 ton of sugarcane can produce 25-300kg of bagasse. Bagasse mainly includes components such as cellulose, hemicellulose and lignin, and also contains a small amount of protein, ash and wax. Therefore, bagasse has great potential fo...

Problems solved by technology

However, due to the low degradation rate of lignocellulosic enzymes, the development of lignocellulosic biomass conversion feed has been gradually limited. In addition, there are many limitations in simply improving the protein evaluation index of feed products. Therefore, how to start from It is more important to improve the flavor of bagasse feed and increase animal feed intake to prepare more promising feed products. At the same time, this idea has gradually been widely accepted by people.

[0004] At present, the commercially available starters are mainly aimed at the production of green straw and straw feed, and the relevant researches are relatively mature. However, there are still few researches on fermentation accelerators for the preparation of air-dried cellulosic biomass. Therefore, the use of air-dried cellulose Biomass is used to prepare feed, so the demand for its fermentation accelerator is extremely urgent

[0005] Yunnan Province is one of the main sugar producing areas in the country. The province has more than 80 sugar-making enterprises, covering 14 prefectures and states in the province, involving more than 40 counties. A large amount of bagasse is produced every year. The current common practice is 90% bagasse It is used as fuel for power generation and steam supply in sugar factory boilers, and the remaining 10% of bagasse is mainly used for papermaking and animal feed production, which not only pollutes the environment, but also greatly wastes resources
