Part I. Studies of the effect of dietary carbohydrate and fat.--Part II. Studies of the effect of adding various fractions of linseed oil meal to the diets, including chemical work on the fractions.

The selenium poisoning problem has attracted much attention in Wyoming and South Dakota. In these two states, the damage to farm animals has been of great concern to farmers and ranchers in certain areas. The search for control measures against selenium poisoning has involved the testing of purified chemical compounds and natural food products. Purified chemical compounds found to be somewhat effective against selenium poisoning have been inorganic arsenicals, organic arsenicals, and bromobenzene. The natural food products which have been found to be somewhat successful with rats and dogs in the treatment of selenium poisoning have been various protein supplements. Other investigators have reported that nutritional factors other than protein are involved in selenium poisoning. Smith reported that the energy source in diets is concerned with selenium poisoning. Moxon reported that the type of protein supplement in diets has an effect upon selenium poisoning. The work reported here, was done to gain additional information on the observations of Smith and Moxon. Part I of this study is concerned with investigations of the relation of energy source to selenium poisoning. Part II is concerned with a continuation of work I the selenium protective factor now known to be present in linseed oil meal.
