Problems solved by technology

[0002] In modern agriculture, the protein intake of animals mainly comes from the protein in soybean meal. The rich protein contained in soybean meal can supplement a large amount of protein for animal growth, but soybean meal contains non-protein anti-nutritional factors, which hinder animals from absorbing nutrients. Absorption and utilization

Embodiment 1

[0012] Soybean meal and bran were mixed at a ratio of 8:3 to make a soybean meal fermentation substrate, and the sterilized Bacillus natto starter was added to the soybean meal fermentation substrate with an inoculation amount of 5%, and fermented at 30°C for 48 hours to obtain a fermented feed.

[0013] The bacillus natto starter is prepared by culturing the bacillus natto at 37°C for 10 hours on a broth slant medium.

[0014] The water content of the soybean meal fermentation substrate is 35%.

[0015] The broth slant medium is made of beef extract, peptone and NaCl in a ratio of 1:2:1.

[0016] The soybean meal and bran are ground and passed through a 40-mesh sieve.

Embodiment 2

[0018] Mix soybean meal and bran at a ratio of 8:3 to make a soybean meal fermentation substrate, add 10% inoculum of the sterilized Bacillus natto starter into the soybean meal fermentation substrate, and ferment at 25°C for 48 hours to obtain a fermented feed.

[0019] The bacillus natto starter is prepared by culturing the bacillus natto at 37°C for 10 hours on a broth slant medium.

[0020] The water content of the soybean meal fermentation substrate is 40%.

[0021] The broth slant medium is made of beef extract, peptone and NaCl in a ratio of 1:2:1.

[0022] The soybean meal and bran are ground and passed through a 40-mesh sieve.

Embodiment 3

[0024] Mix soybean meal and bran at a ratio of 8:3 to make a soybean meal fermentation substrate, add 10% inoculum of the sterilized Bacillus natto starter into the soybean meal fermentation substrate, and ferment at 25°C for 48 hours to obtain a fermented feed.

[0025] The bacillus natto starter is prepared by culturing the bacillus natto at 37°C for 10 hours on a broth slant medium.

[0026] The water content of the soybean meal fermentation substrate is 35%.

[0027] The broth slant medium is made of beef extract, peptone and NaCl in a ratio of 1:2:1.

[0028] The soybean meal and bran are ground and passed through a 40-mesh sieve.

[0029] The degrees of hydrolysis of proteins in the three groups of experiments were 18.57%, 20.53%, and 20.74%, respectively, and the reduction ratios of anti-nutritional factors were 88.37%, 92.85%, and 94.26%, respectively.

Abstract

The invention discloses a preparation method of a fermented feed easy to absorb by animals. The preparation method comprises the following steps of mixing soybean meal with bran at the ratio of the soybean meal to the bran being 8 to 3 so as to obtain soybean meal fermentation substrates, inoculating a sterilized natto bacillus fermentation agent according to the inoculation quantity of 5%-10% to the soybean meal fermentation substrates, and performing fermentation for 48h at 25-30 DEG C so as to obtain the fermented feed. According to the fermented feed disclosed by the invention, the absorption and the utilization of protein by animals can be promoted, the proportion of anti-nutrient factors in the soybean meal is reduced, and the absorption of the animals is promoted.

Description

technical field [0001] The invention belongs to the technical field of animal feed, and in particular relates to a preparation method of fermented feed which is easy for animals to absorb. Background technique [0002] In modern agriculture, the protein intake of animals mainly comes from the protein in soybean meal. The rich protein contained in soybean meal can supplement a large amount of protein for animal growth, but soybean meal contains non-protein anti-nutritional factors, which hinder animals from absorbing nutrients. absorption and utilization. Contents of the invention [0003] The purpose of the present invention is to provide a method for preparing fermented feed that is easy for animals to absorb. In order to realize the present invention, the present invention provides following technical scheme: [0004] A method for preparing fermented feed that is easy for animals to absorb, comprising mixing soybean meal and bran at a ratio of 8:3 to make a soybean mea...
