Abstract
Objective: The objective of this study was to observe baby chicken cardiac structure in different developmental phases to serve in the initial normal stage.
Place and Duration: Services Hospital Lahore, Pakistan. From February, 2017 to February 2018.
Methods: Ninety healthy chicken eggs were classified in three various groups respectively Group I, II and III on the basis of their day of sacrifice. On seventh and tenth day of incubation we classified Group I & II correspondingly; whereas, on twenty-second-day Group III hatched which was also earlier.
Results: On seventh day all heart chamber formed including atrioventricular valves; Whereas, the shape of the semilunar valvular cusps was circular like Primordia. The staining of the elastic fibres was not possible in great vessels on seventh day contrary to tenth day. New hatched heart of the chick was semilunar valvular cusps which was slim and tinny.
Conclusion: Baby Chicken heart is good example to observe the properties of outer teratogens on cardiac development without any nurturing maternal hormonal stress and factors.
