Figure 3.

Dendrogram illustrating the similarity among band patterns obtained with PCR-RFLP among different gastrointestinal segments in pigs fed with a diet with sodium butyrate (AC). Under the curly bracket represented with discontinuous line, the samples of proximal intestinal tracts are grouped; under the curly bracket with solid line the posterior intestinal tracts are clustered. Inside the discontinuous line box the animals euthanized on day 21 are clustered and inside the continuous line box the animals euthanized on day 19 are clustered. The identification of each pig is shown in each sample.
