In the same column, values with the same small or no letter superscripts mean no significant difference (P > 0.05), while with adjacent small letter superscripts mean significant difference (P < 0.05), and with alternate small letter superscripts mean significant difference (P < 0.01).
Abbreviations: AES, average egg size; BS, Bacillus subtilis; DFI, daily feed intake; EM, egg mass. F/E, feed-egg ratio.
