Problems solved by technology

[0006] However, the feed additives for pigs disclosed in the above-mentioned prior art only have excellent effects on different levels. Therefore, it is possible to develop a feed additive that can reduce the cost of breeding, maintain the balance of the intestinal flora of animals, and increase the survival rate of animals. It is suitable for raising various types of pigs, and it is very meaningful to be a feed additive for pigs with multi-faceted advantages such as promoting animal weight gain and improving pork quality.

Embodiment 1

[0054] The present embodiment provides a kind of pig feed additive, and its preparation method is as follows:

[0055] (1) Co-cultivate the mixed flora comprising Lactobacillus acid-fast and Lactobacillus branii in equal proportions for 36 hours at 40°C to obtain a fermentation inoculant;

[0056] (2) Grinding the dry yellow corn stalks produced in the current year to a particle size of 6 mm, and sieving to obtain a standard fermented product;

[0057] (3) Mix the fermented inoculant obtained in step (1) with water and incubate at 37°C for 24 hours to activate it, and mix it with the standard fermented product obtained in step (2) and fermentation auxiliary materials corn flour, 5-aminolevulinic acid, salt , glucose, and cellulase were mixed, and facultative anaerobic fermentation was carried out at 25° C. for 7 days to obtain the pig feed additive. Wherein the ratio of the standard fermented substance to the volume of the fermentation inoculum is 2kg / mL; the mass ratio of th...

Embodiment 2

[0059] The present embodiment provides a kind of pig feed additive, and its preparation method is as follows:

[0060] (1) Co-cultivate the mixed flora containing Lactobacillus acidophilus, Lactobacillus acidophilus, Lactobacillus brinneri, and Lactobacillus fermentum at 50°C for 24 hours to obtain a fermentation inoculant; wherein the total amount of Lactobacillus acidophilus and Lactobacillus acidophilus The ratio of the mass to the total mass of Lactobacillus Brucella and Lactobacillus fermentum is 2:3;

[0061] (2) Grinding the dry yellow corn stalks produced in the current year to a particle size of 5 mm, and sieving to obtain a standard fermented product;

[0062] (3) Mix the fermented inoculant obtained in step (1) with water and incubate at 35° C. for 30 h to activate it, and mix it with the standard fermented product obtained in step (2) and fermentation auxiliary corn flour, 5-aminolevulinic acid, vitamin and glucose were mixed, and facultative anaerobic fermentatio...

Embodiment 3

[0064] The present embodiment provides a kind of pig feed additive, and its preparation method is as follows:

[0065] (1) Co-cultivate the mixed flora containing Lactobacillus acid-resistant, Lactobacillus acidophilus, Lactobacillus brinneri, Lactobacillus fermentum, Trichoderma longifera, and Aspergillus oryzae at 30°C for 72 hours to obtain a fermentation inoculant; wherein the acid-resistant The ratio of the total mass of Lactobacillus and Lactobacillus acidophilus to the total mass of Lactobacillus Brucella and Lactobacillus fermentum is 3:2;

[0066] (2) Grinding the dry yellow corn stalks produced in the current year to a particle size of 8mm, and sieving to obtain a standard fermented product;

[0067] (3) Mix the fermented inoculant obtained in step (1) with water and incubate at 40°C for 20 hours to activate it, and mix it with the standard fermented product obtained in step (2) and fermentation auxiliary materials corn flour, 5-aminolevulinic acid, vitamin , glucos...

Abstract

The invention relates to a pig feed additive and a preparation method and application thereof. The preparation method comprises the steps that co-culture is performed on mixed flora to obtain a fermentation inoculant, cornstalk is preprocessed to obtain a standard ferment, finally, the fermentation inoculant, the standard ferment and fermentation auxiliary materials are mixed, facultative anaerobic fermentation is performed, and the pig feed additive is obtained. The prepared additive can partially replace full-value feed, and therefore the cultivation cost is lowered; the animal intestinal flora can be maintained to be balanced, and the diarrhea rate is lowered; the animal immunity can be improved, resistance can be enhanced, the animal survival slaughtering rate is increased, and excessive use of antibiotic is avoided; weight gaining of animals can be promoted, the metabolism way and the fatty acid structure of animal fat are changed, and the pork quality is improved; the air qualityof the feeding environment is improved, and the environment protection pressure of the breeding industry is solved; the safety food can be traced truly.

Description

technical field [0001] The invention belongs to the technical field of animal feed, and in particular relates to a pig feed additive and its preparation method and application. Background technique [0002] Pork is sweet and salty in nature, rich in protein, fat, carbohydrates, calcium, iron, phosphorus and other ingredients. Pork is the main non-staple food in daily life. In recent years, with the development of the economy and the improvement of people's living standards, people's daily consumption demand for pork has become more and more vigorous, and the pig industry has also developed accordingly, occupying an important position in agricultural and sideline industries, and it is also an economically underdeveloped area. The main source of farmers' economic income. People's requirements for the meat quality of the pork they eat are constantly increasing. Although the current pig feed can meet the nutritional needs of pig growth, it has no effect on improving the quality...
