Abstract

Nodules of 'berne' (larvae of Dermatobia hominis) were counted on both sides of Canchim cattle. The incidence of infestation was greater on the left side of animals than on the right side of animals (means of 14.2 vs. 10.5 nodules). A significant difference (p < 0.001) was found to the preference of sternum-lateral decubitus (i.e. which side the animals preferred to lie on while resting). Of 2360 animals observed, 1183 were resting on their left sides while 1447 were resting on their right sides; it is suggested that this factor may explain the higher incidence of larvae of D. hominis on the left flanks of the ...
