    • Abstract

       

      In animal experiments the Randomised Block Design is quite often used, the blocking based on some characteristics related to the character under study. Evaluation of the relative efficiency of the Randomised Block Design as compared to completely Randomized Design is necessary to decide whether a change of design is warranted. Data from 465 growth and/or protein efficiency ratio (PER) studies were processed to evaluate the relative efficiency of the randomised block design. The randomised block design turned out to be more efficient in growth and PER studies when blocking is based on age, sex and initial weight.
