Simplified methods and equipment used in separation of urine from feces eliminated by heifers and by steers.

T HERE is little information available on methods of separating the urine and feces in balance trials with mature cows and heifers. Forbes et el. (I937) and Briggs and Gallup (i949) reviewed the earlier literature and described acceptable methods for use with steers, involving adaptable commercial separators. The complicated and expensive facilities required for balance trials with steers and heifers have heretofore limited the use of these animals in metabblism experimentation. This paper described an economical and dependable method for holding steers and heifers and simplified equipment that is adequate for the complete separation of the urine and feces eliminated by these experimental animals during short or extended balance studies.
