a
Means in the same column with different letter superscripts are significantly different.
b
Means in the same column with different letter superscripts are significantly different.
P value less than 0.05 is considered significant.
Abbreviations: FC = feed consumption; FCR = feed conversion ratio; No. of chickens = Total number of chickens, and 12 chickens/pen at each time; WG = weight gain.
