Problems solved by technology

However, the in vitro digestion simulation technology is under abnormal physiological conditions, and whether the results can be used to explain the in vivo situation is controversial, so the results of in vitro tests must be verified by strictly controlled in vivo tests

Abstract

An biological evaluation method for forage belongs to the field of forage technology. The method is as below: determining the total energy, crude protein, crude fiber, crude ash, crude fat, neutral detergent fiber, acid detergent fiber and acid detergent lignin of a non conventional forage by using an analytic method of applied chemistry, and then calculating the digestive energy, metabolic energy and net energy of the non conventional forage and evaluating; determining the digestive energy and metabolism energy indexes of animals by using an animal in vivo digestion experiment, and evaluating the nutritional value of the non conventional forage; determining digestive energy and metabolic energy indexes of animals by using an animal in vitro digestion experiment can, and evaluating the nutritional value of the non conventional forage. Applied chemical analysis and animal in vivo and in vitro digestion experiments are combined to establish a nutritional value evaluation system for non conventional forage resources. The method can comprehensively, systematically and accurately evaluate common non conventional forage resources in North china. The nutritional value evaluation system for non conventional forage resources can be utilized to establish an efficient and low-cost forage technology system and realize industrialized demonstration application.

Description

technical field [0001] The invention relates to a method for evaluating the biological value of feed, which belongs to the technical field of feed. Background technique [0002] Unconventional feed ingredients are a relative concept. The feed ingredients used in different regions and different livestock and poultry diets are different. They are unconventional feed ingredients in a certain area or in a certain diet, and in another area or another The ration may be conventional feed ingredients. Different from the raw materials used in traditional diets, unconventional feed raw materials mainly come from agricultural by-products and food industry by-products, and are important feed resources. Unconventional feed ingredients are rarely used in formulations due to less understanding of their nutritional properties and feeding value. Several unconventional feed materials common in the north (such as corn gluten feed, DDGS, corn germ meal, wheat, cottonseed meal, rapeseed...
