Abstract

The objective metrics to evaluate changes in the components of the intestines of broilers fed the diet with the addition of crude glycerin to 7% and to compare the dimensions of these components in the different intestinal portions. This research was carried out in the experimental shed in XXXXXX the poultry sector were selected 16 animals randomly, and these were divided into two groups, one without crude glycerin added to the feed (A), and another with the addition of crude glycerin to feed (B). The animals were fed until 46 days of age, were subsequently euthanized and samples taken from the duodenum jejunum and ileum for histomorphometric assessment and comparison between groups between intestinal portions. Histomorphometric evaluation of the small intestine of the two groups showed a significant difference only in the duodenum, where there was a reduction of villi length in the treatment with the addition of crude glycerin to 7% (172,08 x 132,12 µm; control and treated group, respectively). When comparing the size of the mucosa of the components of each intestinal portion was observed a gradual reduction of villi and crypt and the muscular wall in the cranio-caudal direction. It is concluded that the addition of glycerin in broiler diet reduces the duodenum villus length and the dimensions of the components of the intestinal mucosa decrease in the cranio-caudal direction intestine.
