Effect of feeding different carbohydrates to rats on low protein diets.

The experimental results to be presented here do not demonstrate any significance among the means of the values obtained for the various carbohydrate diets, except for lactose. The results will suggest that the differences between the values for lactose and other diets are significant (PL0.05).No definite trend in the biological value (BV), the net protein utilization (NPU), and the true digestibility (TD) which can be attributed to the influence of the carbohydrates are shown by these results. The various dietary manipulations produce no results significantly different than the values for starch, the exception being lactose. The values for lactose are more than for other sugars.However, the results will show a relationship between a mixture of protein in the diet with the values of the individual protein sources if determined separately. Evidently, the values of each protein in any mixture can be predicted by measuring its TD in the mixture.
