[In vivo estimation of body lipid content of lactating goats based on the heavy water or the urea methods].
Body lipid content of 12 dairy goats was predicted with deuterium oxide (D2O) or urea space (US). With the urea method, lipid prediction was better than with live weight alone (RSD: 1.73 kg vs 2.66 kg) but about half as accurate as with the D2O method (RSD: 0.84 kg).
