Abstract
Results from analyses of weight and body measurement data from 130 normal and 17 Snorter dwarf Hereford calves clearly indicate that the Snorter gene primarily affects longitudinal bone growth and vertebral development in the lumbar and coccygeal region. Its effects upon males were larger than upon females for nearly all characteristics. On the basis of body proportions, heterozygous calves, particularly males, differed from homozygous calves so they would have been selected early in life for preferential treatment at birth and shortly afterward. But individual variation in size and proportions was too large for body measurements alone to be of practical value in distinguishing genotypes among normal calves. Copyright © 1963.
