摘要
Four groups of nutrias of 3- 4 months old were taken as the experimental animals fed with four diet with different digestion energy. The results are that the diet prescriptions which contain different digestion energy result in a extremely significant difference in energy digestibility of nutrias(P<0.01 ), the diet prescriptions which contain different digestion energy result in a extremely significant different in crude protein digestibility of nutrias.(P<0.01 ), the linear relationship presents between different digestion energy and energy digestibility, and the relationship coefficients is 0.8,dE(%)=0.62C(%)-7.18 lnCF(%)+57.78 is the regression equation between energy digestibility and crude fiber and carbohydrate in diets; dE=2985.7+18. 10w is the regression equation between weight gaining of nutrias and digestion energy of nutrias; The difference of gaining weight is extremely significant among different groups of nutrias (p<0.01 ).
