Abstract
A survey of the accumulated experimental evidence suggests that the general effect of genetic differences in body size on input-output relationships in livestock might be largely accounted for by the following two genetic sizescaling rules:1. treat all age and time variables for the ith genotype as directly proportional to Mi0·27, where Mi is the mature body weight of the ith genotype;2. at every age standardized as in (1), treat all cumulated inputs and outputs for the zth genotype as directly proportional to Mi.
