Problems solved by technology

Although the crude protein content of rapeseed meal itself is not low, there is still a certain gap compared with soybean meal, especially the small peptide content in crude protein (the small peptide content is high, which is conducive to the absorption of livestock), which limits the use of rapeseed meal in livestock feed. Applications
[0003] Microbial solid-state fermentation technology is widely used in the feed industry. Its main purpose is to improve product quality through solid-state fermentation. It is mostly used in soybean meal fermented feed. However, there are currently reports on the production of high-quality rapeseed meal using microbial solid-state fermentation technology. less

[0030] Weigh 100g of rapeseed meal, add water according to the proportion of 40%, 45%, 50%, 55%, 60%, and 65% of the total amount of fermented material, and record it as M1, M2, M3, M4, M5, and M6 respectively. NaOH is weighed by 0.6% of the total weight of rapeseed meal dry matter, dissolved in water and added to the raw material of rapeseed meal, after mixing, add 0.4% of the total weight of rapeseed meal dry matter. ), mixed well, and each treatment was repeated 3 times. The fermentation temperature is controlled at 37°C, and the fermentation time is 4 days. After the fermentation is completed, it is dried at 80°C, crushed and passed through a 40-mesh sieve, and the crude protein, small peptide, lactic acid and other indicators are measured.

Abstract

The invention relates to the field of livestock feed, and discloses a fermented feed containing rapeseed meal, and a preparation method of the fermented feed. The preparation method comprises the steps of carrying out solid state fermentation on fermentation raw materials including the rapeseed meal, compound microbial strain, sodium hydroxide and water, and then drying to obtain the fermented feed containing the rapeseed meal. According to the preparation method, lactobacillus plantarum, bacillus subtilis, bacillus licheniformis and saccharomyces cerevisiae are taken as microbial strains for the solid state fermentation of the rapeseed meal, and the aim of remarkably improving the contents of protein and small peptide of the rapeseed meal can be realized in the environment of solid state fermentation in virtue of metabolic activity and interaction of all microorganisms, so that the application of the rapeseed meal in the feed can be further expanded.

Description

technical field [0001] The invention relates to the field of livestock feed, in particular to a rapeseed meal fermented feed and a preparation method thereof. Background technique [0002] Rapeseed meal, also known as rapeseed meal, is a by-product of oil extraction from rapeseed. Its crude protein content should be above 32%, crude fiber content should be below 12%, and it is rich in lysine, major and trace elements , the content of calcium, selenium, iron, magnesium, manganese, and zinc is higher than that of soybean meal, and the content of phosphorus is twice that of soybean meal. At the same time, it is also rich in sulfur-containing amino acids, which are the nutrients that soybean meal lacks. Although the crude protein content of rapeseed meal itself is not low, there is still a certain gap compared with soybean meal, especially the small peptide content in crude protein (the small peptide content is high, which is conducive to the absorption of livestock), which limi...
