A method for uric acid determination in poultry digestibility trials

, : A method for uric acid determination in poultry digestibility trials. Poultry Science 59(3): 662-663

Evaluation of the amount of uric acid in chickens' excreta was examined in order to determine nitrogen catabolism and to estimate acid detergent fibre correctly by the Van Soest method (NAR 34, 1890). Uric acid was determined by a modified enzymic method. Gross fibre, estimated by the Van Soest method, was washed with 0.5% Li2CO3 and then uric acid was also determined on the basis of weight loss. The methods gave similar values for uric acid.
