Means within a column without a common superscript letter differ significantly (p < 0.05). * BC: before challenge. ** PC: post challenge (The challenge with SE was performed at four weeks of age). FCR: feed conversion ratio. a, b, c, d—within a column without a common superscript letter differ significantly (p < 0.05).
