Abstract/OtherAbstract:
Villus growth, enterocyte migration and proliferation were measured in the small intestine of poults (Meleagridis gallopavo) to determine if hen age and/or egg size influences these characteristics during the first week after hatching. At hatching, distal jejunal villi were 22.8 microns longer in poults from the older (48 weeks) versus the younger (34 weeks) hens (P < 0.05). Similarly, labeled enterocytes in distal jejunal sections from poults from the older hens had migrated 28 microns (10%) farther along the crypt-villus axis at hatching, as compared to poults from the younger hens (P < 0.05). Villus growth differences and enterocyte migration were not consistently affected by hen age or egg weight class in poults from 1 to 7 days old. These results suggest that even though intestinal villi may be more advanced developmentally at hatch in poults from the older hens, however post-hatch growth of the intestine or the poult is not affected by hen age or egg weight class.
