ResumoIt is commonly assumed that the conclusions drawn from a feeding comparison made with a single strain of chicken may be applied to other strains and breeds, at least until the results of confirmatory trials are available. Such extrapolation is perhaps encouraged by the fact that interaction between effect of feed and breed is seldom reported. This note, however, reports an instance where the difference in egg production associated with feeding two diets to one breed of domestic fowl was reversed when the diets were fed to another breed. The evidence presented in Table 1 is taken from a trial which was designed to compare the economic performance of four breeds of laying birds in three types of laying cage with two types of feed. Many of the comparisons in the whole design are not relevant to this note, and the data here presented are the complete information about two…
