[An unusual eye defect in Highland cattle: diverging unilateral strabismus]
1Institut für Tierzucht, Ludwig-Maximilians-Universität München.
Abstract:
In the course of an investigation on breeding, management, health and economic problems in seven Highland Cattle farms, two castrated (male) full sibs were detected showing divergent unilateral strabismus (DUS). The reason being found for this eye-defect was a displacement of the M. rectus lateralis by 40 degrees to ventral. Besides DUS, both full sibs were affected by crop ears. It seems probable that DUS is an inborn defect, but the pedigree was not so informative that conclusions on the inheritance of DUS could be drawn.
