Popis: To clarify whether specific damage to intestinal tissue is induced by feeding pigs pigeon pea seed meal (PM), growing pigs were fed soybean meal (SM) or PM, and intestinal villi and epithelial cells on the tip of villi were compared using light and electron microscopy. Fifteen 85-d-old pigs were allotted to three groups of five animals each. Within each group, a pig was randomly assigned to: (1) a conventional (control) diet, (2) SM or (3) raw PM for 10 d. At the end of the experiment three pigs per group were randomly slaughtered. Intestinal villus height, cell area and cell mitosis tended to be highest in the SM group and lowest in the PM group. Dome-like cells were seen on the surface of villi in SM group, but flat cells were observed in the PM group. These histological data suggest that intestinal villi are much more activated in pigs fed SM than PM. However, the fact that physical damage was not observed on the tips of villi in pigs fed PM suggests that raw PM could be used as a plant protein source by adding it as a supplement to conventional diets.
