摘要: The objective of the present study was to assess feeding effects garlic leaf on microbial N supply (MNS), turnover rates plasma phenylalanine (PheTR) and tyrosine (TyrTR) whole body protein synthesis (WBPS) in sheep. sheep were fed either mixed hay (Hay-diet, as control) or plus diet (GL-diet, at a ratio 9:1) crossover design each for 21 day period. isotope dilution method using [(2) H5 ]Phe H2 ]Tyr performed 21st dietary treatment. Nitrogen intake remained similar between diets absorption digestibility higher (P<0.05) GL-diet than Hay-diet. Total purine derivatives excretion MNS greater Plasma PheTR tended be (P=0.06) during GL TyrTR did not differ diets. Further, WBPS (P=0.05) compared with Hence, results suggest that may have positive metabolism by influencing could used potential ruminant feed future.
