Explain the Protein Efficiency Ratio (PER)?

PER method was developed by Osborne, Mendel and Ferry in 1919 and is based on the growth of young rats. The diets usually contain 10% of dietary protein to be tested and are complete in all other dietary essentials. Groups of albino rats (21 days old) are fed for a period of 4 weeks on different diets. Records of the gain in body weight and protein intake of the rats are maintained. The protein efficiency ratio (PER) is calculated using the following formula:

PER, therefore, is a measurement of the efficient utilization of the proteins in the body. You would be interested to know that the egg protein has the highest protein efficiency ratio. Hence, egg protein is the standard to which all other forms of proteins are measured.
