Abstract: Objective To determine the body weight and main organ weight of inbred CMU/1 and CMU/2 inbred Mongolian gerbils, and to explore and establish the biological index system of main organs of Mongolian gerbils. It provides the necessary parameters for animal experiments. Method The body weight and organ weight of the 3～4 month-old gerbil in the inbred line were analyzed statistically. Result The difference between lung coefficient CMU/1 and CMU/2 inbred gerbils significantly, other no significant difference; Kendall coefficient (W) close to 1, the main organs of the overall development of better coordination; linear regression equation, the CMU/1 P<0.05,CMU/2 in the liver, thymus, lung P<0.05, two of the sample had a linear relationship between. The thymus of the liver, spleen, adrenal gland, ovary, pancreas and CMU/2 of CMU/1 was positively correlated with body weight. Conclusion There is significant difference in lung organ coefficient between CMU/1 and CMU/2 inbred strains of gerbil, and there is no obvious influence on the organ coefficient of the gerbil in the inbred line.
