Abstract:
A study was undertaken to investigate the regional variations in the height and width of villi of the small intestine during the pre-hatch development in turkey (Meleagris gallopavo). Sixty embryos of Beltsville White turkey each from third, fourth, sixth, ninth, twelfth, fifteenth, eighteenth, twenty-first, twenty-fourth and twenty-seventh day of incubation and six day-old poults were studied. Routine histological staining was carried out and the micrometrical data was analyzed statistically. Though the foregut, midgut and hindgut of primitive gut was evident by fourth day of incubation, longitudinal foldings of the intestinal epithelium indicating future villi was evident only by fifteenth day embryo. The folds later developed into individual villi which increased in length and width with advancement of age. When the length of villi decreased from duodenum to ileum, the width of villi increased towards ileum.
