Problems solved by technology

However, feed raw materials such as pomace and mulberry powder have unstable sources, unclear ingredients, and most of them are local raw materials, while corn and soybean meal are the main feed raw materials, which are stable in nature, wide in source, easy to ferment, and easy to promote
[0005] Although fermented feed products have emerged in an endless stream in recent years, their production processes are quite different, and their quality varies.
In terms of related reports and patents on using fermented feed to improve the quality of fattening pork, CN105767547A discloses a method for preparing healthy and environmentally friendly fermented compound feed for fattening pigs. The preparation of fermented feed requires two fermentations, which is cumbersome and unfavorable for large-scale conduct
CN 106615806 A discloses a bio-fermented feed for improving pork quality and its production method and application, the growth index of fattening pigs is similar to the result of the present invention, but the amount of soybean meal in the fermented feed is 75-80%, and the cost is relatively high
In the preparation of a kind of TMPF biological fermentation compound feed that can improve pork quality disclosed in CN108185182A, the measurement of meat quality is limited to shear force, and it is difficult to prove its overall influence on other indicators of meat quality

Embodiment 1

[0027] A fermented feed for improving the quality of fattening pork, the preparation method of which is as follows:

[0028] (1) Preparation of fermentation medium

[0029] Preparation of fermentation medium, in which Bacillus activation medium contains yeast powder 0.5-2%, glucose 0.5-2%, peptone 1-5%, potassium dihydrogen phosphate 0.1-0.5%, magnesium sulfate 0.05-0.1%; pentose Pediococcus activation medium contains yeast powder 0.5-2%, glucose 0.5-2%, tomato powder 0.5-1%, potassium dihydrogen phosphate 0.1-0.5%;

[0030] (2) Preparation of fermentation broth

[0031] After the Bacillus subtilis has been activated and purified, single colonies are placed in LB medium, 37°C, 150rpm, and cultivated for 12 hours. When the OD value reaches about 1.0, inoculate 0.1% into the fermentation medium, and culture at 37°C for 24 hours , that is, to obtain the Bacillus subtilis fermentation liquid, the optimal number of viable Bacillus subtilis should reach 1.0×10 8 ~1.0×10 10 CFU / m...

Embodiment 2

[0042] The dietary formula of fattening pigs in the control group was: 67.11% corn, 4% bran, 8% rice bran, 6% rice bran meal, 10.94% soybean meal, 0.87% calcium bicarbonate, 0.35% salt, 0.73% stone powder, 2% premixed material in a blender, fully mixed.

[0043] The formula of 5% fermented feed fattening pig diet is: 69.62% corn, 3.5% bran, 6% rice bran meal, 11.90% soybean meal, 5% fermented feed, 0.87% calcium bicarbonate, 0.35% salt, 0.76% The stone powder and 2% premix are fully mixed in a mixer to obtain a fattening pig feed with a fermented feed content of 5%.

[0044] The formula of 10% fermented feed fattening pig diet is: 71.42% corn, 3.5% bran, 11.08% soybean meal, 10% fermented feed, 0.87% calcium bicarbonate, 0.35% salt, 0.78% stone powder, 2% The premixed material is fully mixed in a mixer to obtain a fattening pig feed with a fermented feed content of 10%.

Embodiment 3

[0046] The dietary formula of fattening pigs in the control group was: 67.11% corn, 4% bran, 8% rice bran, 6% rice bran meal, 10.94% soybean meal, 0.87% calcium bicarbonate, 0.35% salt, 0.73% stone powder, 2% premixed material in a blender, fully mixed.

[0047] The formula of 2% fermented feed fattening pig diet is: 72.72% corn, 3.50% bran, 6% rice bran meal, 11.80% soybean meal, 2% fermented feed, 0.87% calcium bicarbonate, 0.35% salt, 0.76% The stone powder and 2% premix are fully mixed in a mixer to obtain a fattening pig feed with a fermented feed content of 2%.

[0048] The formula of 4% fermented feed fattening pig diet is: 70.42% corn, 3.50% bran, 6% rice bran meal, 12.10% soybean meal, 4% fermented feed, 0.87% calcium bicarbonate, 0.35% salt, 0.76% The stone powder and 2% premix are fully mixed in a mixer to obtain a fattening pig feed with a fermented feed content of 4%.

[0049] The formula of 8% fermented feed fattening pig diet is: 72.60% corn, 3.50% bran, 11.90...

Abstract

The invention discloses fermented feed for improving pork quality and a preparation method and an application thereof. Raw materials fermented by Bacillus subtilis subsp. subtilis ZJUAF-3 and Pediococcus pentosaceus ZJUAF-4 contain abundant probiotics, organic acids and unsaturated fatty acids. The fermented feed obtained by the preparation method is characterized in that the Bacillus subtilis subsp. subtilis viable count is equal to or larger than 1.2x10<9> CFU / g, the Pediococcus pentosaceus viable count is equal to or larger than 2.3x10<9> CFU / g, the formic acid content is equal to or largerthan 45.12 mg / 100g, the acetic acid content is equal to or larger than 98.79 mg / 100g, the propionic acid content is equal to or larger than 1.22 mg / 100g, the lactic acid content is equal to or largerthan 138.45 mmol / kg, the butyric acid content is equal to or larger than 2.98 mg / 100g, the oleic acid content is increased by 3.98%, the linoleic acid content is increased by 7.15% and the linolenicacid content is increased by 0.29%. The fermented feed is used to improve the growth performance and meat quality of fattening pigs.

Description

technical field [0001] The invention belongs to the technical field of fermented feed, and in particular relates to a fermented feed for improving pork quality, a preparation method and application thereof. Background technique [0002] my country is a big pork producing country, and pork production accounts for about 50% of the world's total production. At the same time, pigs are one of the main sources of meat in the dietary structure of our people. Pork consumption occupies an absolute dominant position in meat consumption, and the quality of its meat affects the health of each of us. The evaluation indicators of pork quality mainly include pork meat color score, marbling score, post-slaughter pH, shear force, drip loss; muscle intramuscular fat level, muscle fatty acid composition and content, etc. [0003] With the improvement of living standards, people's requirements for pork quality are increasing day by day, and the measures to improve pork quality are also increas...
