Effect of different diet on young nutrias

Abstract

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<0.0l); 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).
