Feed for rat obese models

Abstract

The present invention discloses a feed for rat obese models. The feed comprises the following components in parts by weight: 25-30 parts of corn, 15-20 parts of wheat, 20-25 parts of soybean meal, 5-12 parts of wheat gluten proteins, 3-10 parts of fishmeal, 10-25 parts of lard, 2.9-9 parts of yeast hydrolyzate, 0.8-1.2 parts of stone powder, 1-2 parts of calcium hydrogen phosphate, 0.5-1 part of compound mineral, 0.1-0.5 part of compound vitamin, 0.1-0.2 part of methionine and 0.1-0.2 part of lysine. The feed is reasonable in fat content, can improve a success rate of the rat obese models, contains the wheat gluten proteins most suitable for absorption of rats, promotes absorption of proteins by the rats, enables the rats to be high in survival rate, is reasonable in component ratios, has synergistic effects, and can significantly improve the success rate of the rat obese models. Nutritional indicators of the feed are line with requirements of the nutritional indicators in national standard GB14924.3-2010 of "Experimental Animal Full Price Nutritional Feeds".

Description

A kind of rat obesity model feed technical field The invention belongs to the technical field of experimental animal nutrition, and more specifically relates to a rat obesity model feed for studying cardiovascular diseases through rat modeling. Background technique With the development of the country's economy, cardiovascular disease has now become the disease that causes the largest number of human deaths. It has become the mainstream of scientists to study cardiovascular disease by using obesity models to create rats with cardiovascular disease. direction. Animal models of obesity include nutritional obesity, genetic obesity, hypothalamus-induced obesity, bilateral ovariectomized obesity, and transgenic obesity. Selecting a suitable obesity model for the experiment is the basis for research. At present, most human obesity is nutritional obesity induced by food. Therefore, giving rats a sufficient amount of high-fat feed every day is one of the important ways to model. ...

Problems solved by technology

However, many experimental observations have shown that the fat-inducing effect of high-fat diets in the past is not significant, and even the rats in the model group are not as fat as the rats in the normal control group that eat ordinary diets.

Conventional high-fat feeds have high fat content and are not easy to absorb protein. Rats have low preference for conventional high-fat feeds and poor nutrient absorption, which leads to extremely low success rate of rat obesity models and often leads to large Rats die from malnutrition
