ABSTRACT
- Nearly all the recognizable symptoms of the syndrome developed in calves restricted to whole milk rations may be temporarily remedied by supplementing the diet with ferric chloride, cupric sulphate, magnesium carbonate and cod liver oil.
- The adequacy of the supplemented ration for sustained normal functions throughout a life cycle including development, reproduction and lactation has not been demonstrated beyond the stage of advanced gestation.
- The most pronounced abnormality that persisted after supplementation was a depraved and erratic appetite, which might have been the consequence of either a dietary deficiency or the physical nature of the ration.
- The remedial results indicate that all the foregoing supplements are essential, but reveals little relative to fundamental etiology of the syndrome.
- In view of the present evidence, it is probable that additional factors should be considered in the etiology of the pathological syndrome resulting from the inadequacy of milk rations for cattle.
