Protein efficiency ratio is –
Protein Efficiency ratio is one of several methods which may be employed for evaluation of quality of protein:
Protein efficiency ratio = Weight increase (in grams) / Gm. of protein consumed
Protein efficiency ratio measures the influence on the weight increase in weaning animals.
Gain in weight per unit of protein consumed
Product of digestibility coefficient and biological value divided by 100
Percentage of nitrogen retained out of the nitrogen absorbed
Percentage of protein absorbed after digestion
