【Objective】 This research was engaged in the study on the change of amino acid profiles rumen degradation for cluster leaf rosinweed and comfrey at different growth stages.【Method】 Six sheep fitted with permanent ruminal cannulas were used to determine the degradation characteristics of amino acid(AA) ruminal incubation by nylon-bag technique for 2 forage grasses at different growth stages.【Result】 The result showed that:1)the contents of amino acid reduced gradually with the growth of 2 kinds of forages.The TAA/CP of cluster leaf rosinweed showed two-peak(high-low-high-low)dynamic pattern.The TAA/CP of comfrey showed singer-peak(low-high-low) dynamic pattern.Two kinds of grasses were rich in aspartic acid,glutamic acid,alanine,valine and leucine,while the content of sulfur amino acids lower.But the amino acid changed at different growth stages with different rules.2) Most amino acids of the Two kinds of grasses in the flowering were not easily degradable in the rumen,showing that amino acids in the rumen of grass flowering had good resistance to degradation for 2 kinds of grasses,especially proline and alanine degradation in the rumen of strong resistance(P0.05).3) In 4 growth periods amino acids were more prone to degradation in the rumen except flowering,while the lysine and arginine were more easily degradable in the rumen grass for 2 kinds of grasses(P0.05).【Conclution】 Two kinds of forage crude protein and amino acids affected by the great variety and growth stage.Lysine and arginine at different growth stages were easier to degradate in the rumen.Proline and alanine had strong anti-degradation in the rumen in flowering period.
