specific Embodiment approach 1

[0045] Specific Embodiment 1: A pig feed for improving immunity according to this embodiment, specifically includes: the feed consists of 20-40 parts of corn, 8-12 parts of rice bran, 3-7 parts of cottonseed cake, and 17-40 parts of fermented soybean meal according to the mass fraction. 23 parts, 5-7 parts of soybean meal, 6-16 parts of meat and bone meal, 2-4 parts of apple pomace, 3-5 parts of hawthorn dregs, 3-9 parts of fermented astragalus dregs, 2-4 parts of yam homogenate, 10 parts of fermented straw ~25 parts, 3~6 parts of green fodder and 0.3~0.5 parts of table salt.

[0046]The effect of this implementation mode:

[0047] The organs and systems of newborn piglets or suckling piglets are not fully developed, and various physiological functions are still weak. Weaning makes the food of piglets change from milk to feed, gastrointestinal vasoconstriction, insufficient blood supply to the mucous membrane, and decreased secretion of digestive juice. Due to the decreased s...

specific Embodiment approach 2

[0052] Specific embodiment two: the difference between this embodiment and specific embodiment one is: the preparation steps of the described fermented soybean meal are as follows:

[0053] Step 1. Mix 60-80 parts of dry soybean meal according to the ratio of dry soybean meal, sugar and water: 10:2-3:15-25, soak at a temperature of 50°C-60°C for 12-36 hours filter;

[0054] Step 2, sterilizing the soaked dry soybean meal at 121°C for 20-40 minutes, cooling to 15-25°C to obtain a fermentation substrate;

[0055] Step 3. Inoculate 2ml per 250g of fermentation substrate with a concentration of 10 7 ~10 9 CFU / g strains, shake well, cultivate at 35-45°C, and cultivate for 12-48 hours to obtain fermented soybean meal; among them, the strains are Bacillus subtilis and yeast with a mass ratio of 1:1; among them, the yeast Concentration is 10 7 ~10 9 CFU / g, the yeast is Angelica Saccharomyces, Bacillus subtilis 10 7 ~10 9 CFU / g; the manufacturer of Bacillus subtilis is Taian Che...

specific Embodiment approach 3

[0056] Specific embodiment three: the difference between this embodiment and specific embodiment one or two is: the main preparation process of the meat and bone meal is:

[0057] ①. Send the inedible broken bone meat from the slaughterhouse or meat processing plant into the crusher and crush it for 30min-45min. The animal carcass is broken into 20mm-50mm pieces of meat in a sealed environment;

[0058] ② Material conveying: send the crushed meat to the drying machine through hydraulic feeding equipment;

[0059] ③. Sterilization and drying: The drying machine conducts heat through heat-conducting oil so that the broken meat can effectively kill germs in an environment with a temperature of 250°C-300°C and an overheating time of 1h-3h. its complete drying;

[0060] ④ Pressing and degreasing: the sterilized and dried meat pieces are sent to the bone extractor through the sealing screw for degreasing and oil extraction to obtain meat and bone meal. Other steps and parameters a...

Abstract

The invention relates to a pig feed for improving immunity and a preparation method of the pig feed. The invention relates to the pig feed for improving immunity and the preparation method of the pig feed. The pig feed for improving immunity and the preparation method of the pig feed are provided for solving the problem that pigs are attacked by pathogenic microorganisms with poor immunity due to unbalanced daily ration. The feed mainly comprises corn, rice bran, cottonseed cakes, fermented soybean meal, soybean meal, meat and bone meal, apple pomace, hawthorn pomace, Chinese yam homogenate, fermented straw, fermented astragalus residues, a green feed and salt. The method specifically comprises the steps of preparing the fermented soybean meal, the meat and bone meal, the Chinese yam homogenate, the fermented straw, and the fermented astragalus residues, performing primary mixing, performing final mixing and the like. The method is applied to the field of pig feed preparation.

Description

technical field [0001] The invention relates to pig feed, in particular to a pig feed for improving immunity and a preparation method thereof. Background technique [0002] With the growth of the economy, the enhancement of consumer demand and the increase of market circulation, the types of diseases in large-scale pig farms have increased to varying degrees. The key to defeat. At present, the factors that affect the immune effect of pigs are as follows: [0003] 1. Unbalanced diet nutrition [0004] The balance optimization of various nutrients in the diet has a special effect on maintaining the best immune status of the body. Insufficiency of any nutrient may affect immunity and enhance the body's susceptibility. [0005] Nutrients are the basic substances to maintain immunity and determine the expression of immune activity. Malnutrition can easily reduce the body's resistance and the phagocytic ability of phagocytic cells, and have a significant impact on the metabol...
