Gross Anatomical Studies on Normal Heart of Buffalo (Bubalus bubalis)

The present research work involved the anatomical account of heart of buffaloes. For this purpose, one hundred normal fresh hearts, 50 each from male and female buffaloes of different ages were randomly collected from the slaughter house of Mirpurkhas city. According to their age and sex, the animals were divided into four i.e. A1 (young male, 1 - 2 years), A2 (young female, 1 - 2 years), B1 (adult male, 3 - 6 years) and B2 (adult female 3 - 6 years). The mean age of buffaloes A1, A2, B1 and B2 groups ranged from 1.2 - 4.2 years. The mean length of anterior border base to apex of heart of buffaloes was 13 15.8 cm. Significant increases in the mean length of anterior border base to apex of the heart and between right and left coronary grooves of heart were observed in adult animals as compared to young animals. The mean length of posterior border from base to apex of heart was 11.8 - 13.9 cm, while a significant increase was observed in the mean length of posterior border base to apex in young males as compared to young females. A significant increase was observed in the mean weight of the heart of male and female buffaloes as the age of animal advances.
