Hematological investigation of dwarf and normal beef cattle

Growth patterns in dwarf and normal Hereford calves

“…He concluded that differences between genotypes were too small relative to the total variation to be of practical diagnostic value. A similar but more extensive study of blood character istics was conducted by Temple (1959) using some of the same and some animals in addition to those used by Swiger. Temple concluded Carrier and clean calves differed significantly in their [blood cell] fragility values, but no accurate classification of individual genotypes was possible.…”

“…A serious limitation of earlier dwarf research with the same group of animals (Bovard, 1954;Bovard et_ al., 1956;Cooper, 1957;Emmerson and Hazel, 1956;Swiger, 1957;and Temple, 1959)…”

“…All animals included in ttiis experiment were purebred (Bovard, 1954;Bovard et_ al., 1956;Cooper, 1957;Emmerson and Hazel, 1956;Swiger, 1957;and Temple, 1959) was that the true genotypes of many animals were unknown. In addition, genotypic comparisons which in cluded cattle from the Missouri inbred line were necessarily confounded with differences in the remaining genetic back ground.…”
