Model customized diet is a type of diet specially designed to meet the requirements of specific scientific experiments. It can be classified into diets for inducing disease models or those that mimic the unscientific and unreasonable diets of humans. Model-customized diet can induce experimental animals to exhibit specific physiological or pathological states and is an important guarantee for precise scientific experiments. For different types of experimental animals (such as mice, rats, rabbits, monkeys, etc.), various disease model-inducing diets can be provided, including those for obesity, type 2 diabetes, fatty liver, atherosclerosis, hyperlipidemia, hypertension, chronic renal failure, hyperuricemia, etc., as well as special diets with adjusted different nutrients. It can precisely control the nutritional components to meet the needs of various complex experiments to the greatest extent.
