ABSTRACT

The gross studies of muzzle were carried out in mithun, yak and zebu. The muzzle appeared to be moist in mithun and yak containing large number of distinct areolae with variable shapes. These areolae were found to be smaller and less moist in zebu, while this was distinct in yak. The muzzle of yak was angular in shape in its ventral part. The philtrum was distinct in yak, while it was found to be shallow in mithun and zebu. The result of analysis of variance showed that the difference in the width of dorsal and ventral margin of muzzle was highly significant (P < 0.01). The critical difference tests revealed that the average width of muzzle was found to be significantly lower in yak in comparison to zebu and mithun
