¹Data are presented in Log₁₀ cfu /g of tissue. Mean ± SE from 12 chickens. ^a-cValues within treatment columns for each treatment with different superscripts differ significantly (P < 0.05). ²Chickens were orally gavaged with 10⁷ cfu of SE per chicken at 6-day old, samples were collected 24 h later. ³Data are presented as positive/total chickens (%). ^∗P < 0.05; ^∗∗P < 0.01.
