Prenatal Development of Heart of Goat (Capra hircus): Morphometric Observations
Abstract:
The study was conducted on 28 foetal hearts of goats of non- descript breed. These were grouped as; Group-I (early prenatal period; ≤50 days of gestation), Group-II (mid prenatal period; between ≥ 51 days to ≤100 days of gestation) and Group III (Late prenatal period; of ≥101 days age till parturition). There were 12 foetii in II and III- group but only four foetii in group-I. The age of goat foetii was estimated by using the standard formula of Hugget and Widas (Singh et al. 1979). The weight and volume of the heart increased continuously from 46th to 148th day of gestation in a colinear fashion, however the maximum gain in weight and volume occurred during the late prenatal period. The percent of heart weight to the body weight goes on reducing with the advancement of age of foetus. During early prenatal period the heart was wider (cardiac shape index 80) while in late prenatal period it was longer (cardiac shape index 65.5) in shape.
