Collection and Analysis of Chicken Urine

Abstract

In connection with experimental nutrition work with chickens it was thought that an analysis of the urine, in the form in which it is excreted by the kidneys, would aid in solving some of the problems, such as the high concentration of uric acid in the blood in the last stages of avitaminosis A. In order to secure such urine it was necessary to provide some means of separation of the urine and fecal material and also to prevent reabsorption of the soluble part of the urine in the cloaca. In most of the work reported on the analysis of hen urine the separation has been accomplished by operation methods, essentially of two types. In one method an artificial anus is formed in the anterior abdominal wall and the urine and feces are then collected in rubber bags. (Minkowski1, Milroy2, Katayama4, and others.) The other operative procedure consists of insertions . . .
