High-fat purified feed establishing metabolic syndrome animal model and processing technology

Abstract

The invention discloses high-fat purified feed establishing a metabolic syndrome animal model and a processing technology, wherein the high-fat purified feed has good stability, conforms to the eating habits of rodents and ensures that the designed ingredients are not damaged. The high-fat purified feed comprises the following raw materials in parts by weight: 20.0-25.0 parts of casein, 8.0-10.0 parts of starch, 18.0-20.0 parts of sucrose, 2.0-3.0 parts of vegetable oil, 18.0-22.0 parts of animal fat, 5.0-6.0 parts of cellulose, 0.2-0.5 part of L-cystine, 1.0-2.0 parts of dicalcium phosphate, 0.5-1.0 part of calcium carbonate, 1.5-2.0 parts of potassium citrate, 0.15-0.25 part of choline bitartrate, 1.0-2.0 parts of composite minerals, 1.0-1.5 parts of vitamin complex and 10.0-12.0 parts of maltodextrin. The high-fat purified feed disclosed by the invention has good stability and balanced nutrition and is suitable for rodents.

Description

technical field [0001] The invention relates to the technical field of building medical models, in particular to a high-fat purified feed and a processing technology for building metabolic syndrome animal models. Background technique [0002] At present, the incidence of metabolic syndrome in my country is greater than 15%, with more than 200 million patients. According to the results of a random sample survey of Chinese adults, the prevalence rates of metabolic syndrome among overweight and obese people are 21.6% and 29.6%, respectively. Metabolic syndrome has become a new chronic disease and public health problem. The high incidence of metabolic syndrome has brought a heavy burden to society and economy, and it is a worldwide problem that seriously threatens human health. In order to study the pathogenesis of metabolic diseases in depth, researchers urgently need to establish rodent models with the physiological changes characteristic of metabolic syndrome. Currently, a...

Problems solved by technology

The feed in this case has the following problems: 1. Most of the materials in the formula are not purified substances. Most of the raw materials, such as corn, flour, pork floss, grass powder, fish meal, bran, etc., have strong seasonality, and the regions of origin Complicated, which makes the nutrient content in it uneven, resulting in insufficient feed stability and poor reproducibility

2. The nutritional structure of this kind of feed is not comprehensive, it can only be used for fattening, and it lacks some necessary substances for animals, so it cannot form a stable model disease

3. This kind of formula is difficult to process at low temperature into a pellet feed that meets the hardness and taste of rodents. In other words, some of the effective components will be destroyed by conventional processing (temperature 102-110°C)

[0004] To sum up, currently this kind of feed processing is carried out at high temperature, which will destroy some material components in the feed, resulting in the destruction of the nutritional content of some components

[0005] The Publication No. CN101181024A announced by the State Intellectual Property Office on May 14, 2008, titled "Soft Pellet Compound Feed for Suckling Pigs and Processing Technology", discloses a technical solution for granulating soybeans, corn, etc. at room temperature; it is undeniable Its feed can be granulated, but those skilled in the art can be sure that it cannot achieve the hardness and taste that meet the eating habits of rodents according to its components and processes
