Abstract :A total of 1000 beef cattle were examined after being slaughtered, of which 373 were Holstein and 627 were Brown Swiss. The high incidence of lens abnormalities was observed to be as follows: coloboma (20.4%), microphakia (6%) and cataract (3.9%) in Holsteins for a total incidence rate of 30.3%, and coloboma (5.6%), microphakia (2.6%) and cataract (4.2%) in Brown Swiss for a total incidence rate of 12.4 %. Holsteins were more frequently affected than Brown Swiss with coloboma and microphakia, but not with unilateral cataract formation. These animals were generally fed different ratios of beet pulp, hay, molasses and barley bought from a variety of sellers.Keywords : Coloboma, microphakia, cataract, Holstein, Brown Swiss
