This experiment was carried out to study the influences of shearing of pig hair on the pig growth and the differences between individuals and in the various parts of the pig for the hair growth rate after shearing. The results obtained were as follows: 1. The difference for the hair growth rate after shearing was found significant (p.$lt;0.01) between individuals. Berkshire pigs had the highest hair growth rate and Landrace pigs had the lowest. 2. The highly significant differences (p.$lt;.0.01) for the hair growth rate after shearing was found between the parts of pig. The growth rate of hair: on the forequarters and back was higher than those on the bully and hindqueters. 3. No appreciable difference for body weight gain was found between control pigs and sheared pigs through the whole experimental period.
