Abstract

The study included detection of the sites of ossification centers and their sequence of appearance in the forelimb bones of indigenous sheep fetuses by using double staining method with younger specimens and radiography or maceration methods with old specimens, as well as, histological study with some ages. The results showed that the primary ossification centers of the forelimb in indigenous sheep fetuses appeared firstly in the diaphyses of radius and ulna, humerus, scapula, metacarpus, phalanges and lastly in the carpal bone at an estimated age of 43, 45, 46, 47, 49 - 56 and 90-118 days old respectively. The results of statistical analysis of the total lengths of scapula, humerus, radius, ulna and metacarpus with the lengths of their ossified parts through the 7th – 15th weeks of fetus age, showed presence of significant differences in the average of these measurements among most of studied weeks. Also there was a significant differences in the average of relative increase in the total length and length of ossified part of diaphysis of studied bones during the 7th week in comparison to the same average in the other studied weeks (8th-15th week) of indigenous sheep fetuses age.
