Evaluation of urea dilution as a technique for estimating body composition of beef steers in vivo: validation of published equations and comparison with chemical composition



Evaluation of urea dilution as a technique for estimating body composition of beef steers in vivo: validation of published equations and comparison with chemical composition



Journal of Animal Science 63(6): 1935-1948



Urea dilution equations for prediction of empty body water in live cattle were evaluated by comparing empty body water calculated by these equations with that measured chemically in 6-, 12- and 18-month-old crossbred beef steers (10, 9 and 9 resp.). Of 4 equations for prediction of empty body water percentage, one, derived from data on several breeds of steers, overestimated empty body water in the 6-month-old steers by 7.59% (P<0.05).
