Dendograms showing clustering of the DGGE profiles of
feces based on pairwise correlation coefficients are presented
in Fig. 3. The similarity indices in profiles of the individual
pigs ranged from 0.43 to 0.73. In general, with some exception,
the fecal communities in piglets formed different small
clusters according to the type and abundance of additive included
in the diet. For example, BV2 and the control diet
tended to cluster together and separate from antibiotics,
BV4 and BV8 which also cluster together (Fig. 3).
