preparation example 1

[0046] The anti-heat stress additive is prepared by the following method:

[0047] Mix threonine, arginine, vitamin C, γ-aminobutyric acid, and Bacillus subtilis microecological preparations evenly to obtain a compound anti-heat stress additive.

preparation example 2

[0049] γ-aminobutyric acid is prepared by the following method:

[0050] A1. Add 8g of sodium chloride to 460g of water, dissolve and mix evenly, then add 190g of potassium hydroxide, dissolve and mix evenly to form an alkaline environment, then add 210g of 2-pyrrolidone, heat up to 125°C, add Press down to 0.3MPa, keep warm for 8 hours, cool down to 60°C, filter to obtain filtrate;

[0051] A2. Add ethanol to the filtrate to concentrate to make its volume 1 / 3 of the original volume, and then use 720 cationic column for adsorption. The gamma-aminobutyric acid in the filtrate is adsorbed on the surface of 720 cationic column, and then use a weight fraction of 30 % ammonia solution for elution, and γ-aminobutyric acid is desorbed from the surface of the 720 cationic column and dissolved in ammonia solution to obtain the eluent;

[0052] A3. Add hydrochloric acid solution with a weight fraction of 15% in the eluent, adjust its pH value to 6.5, then add ethanol to concentrate to ...

preparation example 3

[0054] γ-aminobutyric acid is prepared by the following method:

[0055] A1. Add 10g of sodium chloride to 480g of water, dissolve and mix evenly, then add 210g of potassium hydroxide, dissolve and mix evenly to form an alkaline environment, then add 240g of 2-pyrrolidone, heat up to 127°C, add Press down to 0.29MPa, keep warm for 9 hours, cool down to 65°C, filter to obtain filtrate;

[0056] A2. Add ethanol to the filtrate to concentrate to make its volume 1 / 3 of the original volume, and then use 720 cationic column for adsorption. The gamma-aminobutyric acid in the filtrate is adsorbed on the surface of 720 cationic column, and then use a weight fraction of 30 % ammonia solution for elution, and γ-aminobutyric acid is desorbed from the surface of the 720 cationic column and dissolved in ammonia solution to obtain the eluent;

[0057] A3. Add hydrochloric acid solution with a weight fraction of 10% to the eluent, adjust its pH value to 7, then add ethanol to concentrate to ...

Abstract

The invention relates to a compound feed for lactation sows and a preparation method of the compound feed, and belongs to the technical field of a pig feed. The compound feed comprises the raw materials of corn, soybean meal, corn germ meal, DDGS, rice bran meal, calcium hydrogen phosphate, stone powder, edible salt, complex vitamins for breeding boars, trace elements for breeding boars, soybean oil, an antioxidant, a solid mildewproof agent, a sweetening agent, high temperature resistant phytase, choline chloride, bile acid, and heat resistant stress additive, wherein the heat resistant stress additive comprises the raw materials of threonine, arginine, vitamin C, gamma-aminobutyric acid, and a bacillus subtilis microecological preparation. According to the compound feed for lactation sows, the food consumption of bodies of the sows can be increased, the intake quantity of nutrients is increased, mammogenesis is promoted, heat stress of the bodies of the sows can be relieved, the conversion rate of the compound feed is increased, and comprehensive production performance of the bodies of the sows can be improved. According to the preparation method of the compound feed, steam granulation and rotary drying for two times are adopted, so that the surface heating uniformity of the compound feed is improved, and the compound feed is simple to prepare, convenient to shape and convenient to control.

Description

technical field [0001] The invention relates to the technical field of pig feed, more specifically, it relates to a compound material for sucking sows and a preparation method thereof. Background technique [0002] Lactating sows refer to pregnant sows that are in the lactation period after giving birth. The levels of energy, protein, calcium, phosphorus and other nutrients required by lactating sows need to meet the sow's own body weight and milk production requirements. In hot summer, lactating sows are prone to heat stress due to the influence of ambient temperature. Heat stress refers to the sum of non-specific physiological responses made by the thermal environment to any request made by the body when the body is in a high-temperature environment, and is the animal's response to internal and external stimuli or challenges. Sows are endothermic animals, and there is an isothermal zone. Within this range, sows maintain normal body temperature by means of physical regulat...
