| This work reports the use of scanning electron microscopy to evaluate intestinal epithelium loss in broilers. Intestinal mucosa of male and female chicks submitted to prolonged period post-hatching of water and feed deprivation was evaluated. Two segments of the duodenum, jejunum and ileum were taken per bird, and routinely processed by scanning electron microscopy. Six distinct degrees of epithelium loss were determined: degree 0, normal villi without apparent extrusion; degree 1, villi presenting small areas of epithelium loss; degree 2, villi without epithelium at the apex; degree 3, villi without epithelium at the apical region; degree 4, villi without epithelium in the upper half; degree 5, lack of epithelium in the whole villus; degree 6, loss of... |
