In situ nylon bag technique was a common method to evaluate the nutritional value of feed for rumi-nant.However,there were many factors affecting the determination of feed nutritional value,and there were problems between laboratories and even in the same laboratory.The paper reviewed the progress of relevant ex-perimental studies on inconsistencies in evaluating feed nutritional value,and based on the results of these stud-ies,some new technical regulations for evaluating rumen protein degradation rate of using this in situ nylon bag technique were recommended in sheep.At the same time,suggestions were given for the application of this technology in cattle,and references were provided for further research and make standards related with in situ nylon bag technique.[Chinese Journal of Animal Nutrition,2024,36(11):6801-6807]
