| description | Traditional Chinese medicine (TCM) encompasses a wide range of natural herbs and plants that are used to treat or prevent diseases or promote health. This study aimed to evaluate the effect of feeding a TCM formula extract on nitrogen (N) balance, microbial nitrogen supply (MNS), and plasma leucine kinetics in sheep. Six sheep were fed with mixed hay (Hay-diet) only or supplemented with 2% TCM (mixture of Astragalus root, Angelica root, and Atractylodes rhizome; TCM-diet) in a crossover design over two 21-day periods. An isotope dilution of [1-<sup>13</sup>C]leucine was used to measure the rate of plasma leucine turnover. Purine derivative (PD) excretion in urine was determined to estimate the MNS. The TCM-diet significantly increased N intake (<i>p</i> < 0.01) and N digestibility (<i>p</i> = 0.02) compared to the Hay-diet, with less N excretion (<i>p</i> = 0.02) in feces, while no significant difference was observed between diets in terms of N excretion in urine and N retention. Total PD excretion and MNS were higher (<i>p</i> < 0.01), as well as the turnover rate of plasma leucine tended to be higher (<i>p</i> = 0.06) with the supplementation of TCM. The present results suggested that the TCM formula could be considered as a potential feed additive for ruminant production. |
