Studies on the Effects of a Bovine-Blindness-Producing Ration Upon Rabbits

(Abstract. Complete article to be published in the Journal of Nutrition)

University of Wisconsin

Abstract

Blindness of cattle caused from stenosis of the optic foramen has been shown by Reed and associates (1), Huffman (2), and Walker (3) to be due to defective nutrition. The exact cause of this type of blindness has not been determined. Studies have been made with laboratory animals in an attempt to determine the causative factor or factors involved in this disease. The basal ration used was that reported by Walker (3) and was composed of white corn 22 parts, linseed meal 23 parts, standard wheat middlings 11.5 parts, oat mill feed 40 parts, ground limestone 3 parts, iodized salt 0.5 parts, and 0.1 part of irradiated yeast.

A series of experiments with rabbits has shown that the Walker ration (3) which caused optic foramen stenosis in the growing calf failed to produce stenosis in the rabbit. It is believed that the failure was due to the anatomical arrangement of the rabbit skull since the syndrome developed in the rabbit was otherwise strikingly similar to that produced in calves.
