The growth method of comparing the nutritive value of proteins, namely the estimation of protein efficiency ratio (P.E.R.) has long been popular because of its simplicity dspite its well-known drawbacks (Mitchell, 1944). Among the serious disadvantages of this method are: no allowance is made for maintenance requirements of the test animal, the result varies with food intake, and the assumption the gain in body-weight is indicative of the protein tissue laid down is not always valid. A modification is described whereby a control groupfo animals fed on a protein-free diet is included in the experiment, and the difference betwen the weights of this group and the test group is used in the calculation instead of merely weight gain. |
