a, bMeans in a column not sharing a common superscript were different (P < 0.05).
Carcass weight = chicken BW without the proventriculus, gizzard, heart, liver, pancreas, bursa of Fabricius, spleen, or intestine.
SEM = standard error of mean; n = 16 and 40 for treatments of strain and diet, respectively.
When the results of interaction were not significantly different, the data of means were not shown in the table.
