| Abstract | ||||
| The p < /strong>ost-hatchery developmental changes in the oviduct of high (Hy-Line) and low (Dandrawi) egg-producing fowl were studied in the p < /strong>eriod from the first day to 24 weeks after hatching. The morphometerical studies of the oviduct in both breeds revealed that, the increase in the oviduct length for both breeds was slow till the 16th weeks of age. At the 20th weeks of age, the oviducal length was markedly longer for Dandrawi than that for Hy-Line. The average length was 17 cm and 10 cm for both breeds, respectively. At 24 weeks of age, the oviducal length for Hy-Line was higher than for Dandrawi breed. Their average length was 75 cm and 70 cm in both breeds, respectively. Moreover, the diameter and the thickness of the oviduct, the height of lining epithelium as well as the height of the mucosal folds in the different segments of the oviduct in both Hy-Line and Dandrawi breeds were recorded. | ||||
