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

[0028] The steps of the oligopeptide preparation method are as follows:

[0029] (1) Sterilization

[0030] Soy protein and rapeseed protein are made up of 5:1 enzymatic hydrolysis raw materials, add water to make the liquid-solid ratio 5:1, pasteurize or maintain at 80°C for 10 minutes to sterilize. Soy protein is a mixture of any one or more of protein concentrate, 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 .

[0031] (2) Enzymatic hydrolysis

[0032] Cool the material and keep it at 35°C, adjust the pH to 6.5, add the Bacillus subtilis neutral protease according to 1.0% (weight ratio) of the soybean protein content, and carry out enzymatic hydrolysis for 2 hours (enzymatic hydrolysis). Activity definition: Under the conditions of pH 6.5 and temperature of 35℃, the enzyme required for the reaction of 5% trichloroacetic acid solubles released by hydrolyzing standar...

Embodiment 2

[0040] The steps of oligopeptide preparation method are as follows:

[0041] (1) Sterilization

[0042] Soy protein and rapeseed protein are composed of 5:2 enzymatic hydrolysis raw materials, add water to make the liquid-solid ratio 10:1, pasteurize or maintain at 85°C for 30 minutes to sterilize. Soy protein is a mixture of any one or more of protein concentrate, 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 .

[0043] (2) Enzymatic hydrolysis

[0044]Cool the material and keep it at 40°C, adjust the pH to 7.0, add the Bacillus subtilis neutral protease according to 1.5% of the soybean protein content (weight ratio), and carry out enzymatic hydrolysis for 3 hours (enzyme Activity definition: Under the conditions of pH 7.0 and temperature of 40℃, the enzyme required for the reaction of 5% trichloroacetic acid solubles released by hydrolyzing standard casein within 1 M...

Embodiment 3

[0052] The steps of oligopeptide preparation method are as follows:

[0053] (1) Sterilization

[0054] Soy protein and rapeseed protein are composed of enzymatic hydrolysis materials at 5:1.5, add water to make the liquid-solid ratio 7.5:1, pasteurize or maintain at 82.5°C for 20 minutes for sterilization. Soy protein is a mixture of any one or more of protein concentrate, 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 .

[0055] (2) Enzymatic hydrolysis

[0056] Cool the material and keep it at 37.5°C, adjust the pH to 6.75, add the Bacillus subtilis neutral protease according to 1.25% (weight ratio) of the soybean protein content, and carry out enzymatic hydrolysis for 2.5 hours (enzyme) Activity definition: Under the conditions of pH 6.75 and temperature 37.5℃, the enzyme required for the reaction of 5% trichloroacetic acid solubles released by hydrolyzing standard ...

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 nutritional 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 generally concerned in intensive pig production at home and abroad. Early weaning can increase the reproductive rate of sows and increase the number of sows per year. , Reduce the transmission of diseases from the mother to the piglets, and can improve the production performance and carcass quality of growing pigs, and at the same time can increase the utilization rate of equipment such as farrowing rooms. At present, countries with developed pig industry have begun to promote the application of 14-day-old ultra-early weaning technology. But an important problem brought about by early weaning is how to improve the growth performance of weaned piglets. The nature of the diets after weaning of piglets has undergone major changes, and the d...
