Being the National Standard, if it is too far from the reality of the filed, weighing and changing should be made.Hardness/crispness degree of laboratory animal diet never been considered as a listed value in the National Standard for Laboratory Animal to identify the quality of diet.In fact, this index affects a lot about daily diet intake and physiological status of laboratory animals.Hereby, the authors suggest to take the index into the National Standard, to assess the quality of laboratory animal diet in a more comprehensive way.
