Morphometric characteristics duodenal of broiler chickens cross ROSS 308 after 15- and 21-day postnatal period

The article presents the results of morphometric analysis of broiler chickens ROSS 308 duodenal ulcer at the age of 15 and 21 days post-natal period. The duodenal mucosa villi are finger-like and leaf-shaped. The height of the villi after 15 days of postnatal development in the proximal (at a distance of 5 mm from the pylorus), and distal (10 mm below the major duodenal papilla) duodenum departments varies, 21 days is an increase in the height of the villi in the proximal (p
