Problems solved by technology

Another example is the use of exogenous small molecule active peptides to eliminate the absorption competition of free amino acids, promote the secretion of hormones, promote the absorption and utilization of mineral elements, and improve production performance, but active small peptides cannot solve the intestinal mucous membrane injury

Embodiment 1

[0021] The steps of the oligopeptide preparation method are as follows:

[0022] (1) Sterilization

[0023] Soybean protein and rapeseed protein are composed of 5:1 enzymatic raw materials, water is added to make the liquid-solid ratio 5:1, pasteurization is carried out or sterilization is maintained at 80°C for 10 minutes. Among them, soybean protein is a mixture of any one or more of concentrated protein, defatted soybean meal, soybean meal, and soybean cake in any ratio; rapeseed protein is a mixture of one or two of rapeseed meal and rapeseed cake in any ratio .

[0024] (2) Enzymolysis

[0025] Cool the material and keep it at 35°C, adjust the pH value to 6.5, add Bacillus subtilis neutral protease according to 1.0% (weight ratio) of soybean protein content, and perform enzymatic hydrolysis for 2 hours (enzyme activity ≥ 50,000 U / g) Vitality definition: at pH 6.5 and temperature 35°C, the absorbance of 5% trichloroacetic acid solubles released from the hydrolysis of st...

Embodiment 2

[0033] The steps of the oligopeptide preparation method are as follows:

[0034] (1) Sterilization

[0035] Soybean protein and rapeseed protein are composed of 5:2 enzymatic hydrolysis raw materials, water is added to make the liquid-solid ratio 10:1, pasteurized or sterilized at 85°C for 30 minutes. Among them, soybean protein is a mixture of any one or more of concentrated protein, defatted soybean meal, soybean meal, and soybean cake in any ratio; rapeseed protein is a mixture of one or two of rapeseed meal and rapeseed cake in any ratio .

[0036] (2) Enzymolysis

[0037]Cool the material and keep it at 40°C, adjust the pH value to 7.0, add Bacillus subtilis neutral protease according to 1.5% (weight ratio) of the soybean protein content, and perform enzymatic hydrolysis for 3 hours (enzyme activity ≥ 50,000 U / g) Definition of activity: at pH 7.0 and temperature 40°C, the enzyme required when the absorbance of 5% trichloroacetic acid solubles released from the hydrolys...

Embodiment 3

[0045] The steps of the oligopeptide preparation method are as follows:

[0046] (1) Sterilization

[0047] Soybean protein and rapeseed protein are enzymatically hydrolyzed at a ratio of 5:1.5, water is added to make the liquid-solid ratio 7.5:1, pasteurization is carried out or sterilization is maintained at 82.5°C for 20 minutes. Among them, soybean protein is a mixture of any one or more of concentrated protein, defatted soybean meal, soybean meal, and soybean cake in any ratio; rapeseed protein is a mixture of one or two of rapeseed meal and rapeseed cake in any ratio .

[0048] (2) Enzymolysis

[0049] Cool the material and keep it at 37.5°C, adjust the pH value to 6.75, add Bacillus subtilis neutral protease according to 1.25% (weight ratio) of soybean protein content, and perform enzymolysis for 2.5 hours (enzyme activity ≥ 50,000 U / g) Definition of activity: at pH 6.75 and temperature 37.5°C, the enzyme required when the absorbance of 5% trichloroacetic acid solubl...

Abstract

An intestinal nutrition peptide as an additive of feed for piglet is prepared from one or more of oligopeptide, plycyl-L-glutamine, alanyl glutamine and iron glycinate. It can prevent the delactation stress of piglet and can be used to replace to plasma albumin powder. Said oligopeptide is prepared from soybean protein and rapeseed protein through sterilizing, enzymolyzing, deactivating enzyme and ultra-filtration.

Description

technical field [0001] The invention relates to a piglet intestinal nutrition peptide. Background technique [0002] In pig production, the key link is the production of weaned piglets. Early weaning of piglets is an advanced technology that is widely concerned in intensive pig production at home and abroad. Early weaning can improve the reproductive rate of sows and increase the annual litter size of sows , reduce the disease transmission from the mother to the piglets, and can improve the production performance and carcass quality of the growing pigs, and at the same time can increase the utilization rate of equipment such as the farrowing room. At present, countries with developed pig farming industry have begun to promote the application of 14-day-old ultra-early weaning technology. However, an important problem brought about by early weaning is how to improve the growth performance of weaned piglets. After weaning, the nature of the diet of piglets has undergone major ...
