a-dMeans in a column not sharing a common superscript were different (P < 0.05).

1

Abbreviation: YFBW = yolk-free body weight.

2

Temp was the abbreviation of temperature and measured in the cloaca of broilers.

3

Carcass weight was BW without internal organs including the proventriculus, gizzard, heart, liver, pancreas, bursa, spleen, and intestine.

4

SEM = standard error of mean; n = 16, 40, and 8 for treatments of strain, diet, and interaction of strain, respectively, and diet for day 8, 22, 40, and 60. N = 4 for day 0.

5

Carcass weight for day 40 and 60 are listed in Tables 7 and 9.
