Fermented soybean meal for medium-large pigs and preparing method thereof

Abstract

The invention discloses fermented soybean meal for medium-large pigs and a preparing method thereof. The fermented soybean meal comprises, by weight, 250-300 parts of high-quality soybean meal, 0.6-0.8 part of seed powder of Chinese prickly ash, 0.1-0.2 part of leavening agents, 30-40 parts of animal blood meal, 20-24 parts of dried grain of distiller, 10-14 parts of oat bran, 4-7 parts of orange leaf powder, 2-3 parts of barley grass, 3-4 parts of boxthorn leaves, 2-3 parts of lemon grass, 3-4 parts of polygonum multiflorum leaves, 4-6 parts of apple peels, 0.5-0.8 part of salt, 0.4-0.6 part of ginger oil, 0.2-0.4 part of chicken powder, 1-2 parts of dark plum juice and 3-4 parts of duck bone micro powder. The fermented soybean meal has unique fermentation flavor, tastes unique and is excellent in food calling, capable of increasing animal appetite, increasing animal food consumption, promoting growth and weight increment, increasing the fattening rate, lowering material consumption and lowering the feed cost; furthermore, the fermented soybean meal further promotes the gastroenteric function of animals, promotes the healthy growth and development of animals and improves the immune function of animals.

Description

technical field [0001] The invention relates to the technical field of animal breeding, in particular to a fermented soybean meal for medium and large pigs and a preparation method thereof. Background technique [0002] The crude protein content in soybean meal is as high as 30%-50%, which is one of the main protein feeds for animals. However, untreated soybean meal contains anti-nutritional factors such as trypsin inhibitors, oligosaccharides, lectins, phytic acid, and urease. It will have adverse effects on the digestion and utilization of animals and feed. Through microbial fermentation, the anti-nutritional factors in soybean meal can be degraded or inactivated, thereby improving its utilization. Soybean meal protein has strong antigenicity, which can cause intestinal allergies in animals, and then cause diarrhea in animals. Studies have confirmed that this part of the antigenic protein is mainly glycinin and β-conglycinin, and through microbial fermentation, these antig...

Problems solved by technology

At present, although the utilization rate of fermented soybean meal obtained by traditional fermentation technology has been improved, the flavor of the fermented product is poor, and the attraction to animals is not good. The advantages of using soybean meal as animal feed have not yet been fully demonstrated. Improving and optimizing the fermentation process, and developing a new type of fermented soybean meal with excellent food-attracting properties, unique feed flavor, and improved animal growth and reproduction performance is an important problem that should be solved at present.
