[Objective] The aim of this study was to provide a theoretical basis for population and application of Chinese herbal feed additive in the rex rabbit breeding. [Method] 108 weaned-rex rabbits aged 40 days were divided into three groups with thirty-six each group. Group A were fed basal diet, while group B were fed basal diet supplemented with 0.3% Chinese herbal feed additive and group C were fed basal diet supplemented with 0.4% Chinese herbal feed additive. The meat quality indexes were measured when feeding to 150 age in days. [Result] There was significant difference among pH value, water loss rate, storing loss rate and crude protein content in each group (P＜0.05), but no significant difference was found in tenderness, cooking percentage, moisture content and crude fat content (P＞0.05). The total content of amino acids, essential amino acids and semi essential amino acids as well as main delicious amino acids was highest in group C accounting for 23.84%, 11.47% and 8.32% respectively, next came group B accounting for 20.94%, 10.64% and 6.81% respectively, and lowest in group C (control group) accounting for 19.06%, 9.61% and 6.46% respectively. [Conclusion] The Chinese herbal feed additive can improve meat quality of rex rabbit the best addition of 0.4%.
