1Data are expressed as Log10 cfu/g mean ± SE.
2Bacteria enumeration evaluated from 28-day-old broilers, n = 16/group.
3Forgut: from duodenum to Meckel's diverticulum, hindgut: from Meckel's diverticulum to ceca.
4TGNB = Total Gram-negative bacteria recovered, TLAB = Total lactic acid bacteria recovered, TAB = Total anaerobic bacteria recovered from different intestinal sections in each experimental group.
a,bMeans in each column with different superscripts are significantly different (P < 0.05).
