The experiment was aimed to study the effect of Amomum tsao-ko stems and leaves on growth performance,serum indexes,and meat quality of Xichou Wugu chicken.Two hundred seventy Xichou Wugu chickens with about 28 days of age were divided into 3 groups with three replicates in each group with 30 chickens in each replicate.The chickens were fed the basal diet as control group,the basal diet supplemented with 3％Amomum tsao-ko stems and leaves was experimental group Ⅰ,and the basal diet supplemented with 6％Amomum tsao-ko stems and leaves was experimental group Ⅱ.The experiment period was 90 days.The results showed that:(1)Compared with control group,the average daily feed intake in groupⅡ was increased by 4.83％(P＜0.05);The average daily gain in test groups Ⅰ and Ⅱ was increased by 3.53％and 7.19％(P＜0.05),respectively;The gain feed ratio in test groups Ⅰ and Ⅱ was decreased by 2.83％and 1.63％(P＜0.05),respectivel;(2)Compared with control group,the contents of mositure in muscle in test groups Ⅰ and Ⅱ was increased by 0.08％and 0.61％(P＜0.05),respectively;The contents of protein in muscle in test groups Ⅰ and Ⅱ was increased by 6.9％and 6.3％(P＜0.05),respectively;The contents of fat in muscle in test groups Ⅰ and Ⅱ was increased by 8.05％and13.1％(P＜0.05),respectively;(3)Compared with control group,the total contents of amino acid in muscle in test groups Ⅰ and Ⅱ was increased by 5.27％and 5.57％(P＜0.05),respectively;the total contents of essential amino acid in muscle in test groups Ⅰ and Ⅱ was increased by 7.59％(P＜0.05);(4)Compared with control group,the total contents of fatty acid in muscle in test groups Ⅰ and Ⅱ was increased by 49.58％and 52.55％(P＜0.05),respectively;The total contents of mono-unsaturated fatty acid in muscle in test groups Ⅰ and Ⅱ was increased by 239.94％and 252.56％(P＜0.05),respectively;The total contents of polyunsaturated fatty acid in muscle in test groups Ⅰ and Ⅱ was increased by 69.10％and 72.11％(P＜0.05),respectively;The experiment indcated that adding Amomum tsao-ko stems and leaves to feed could improve growth performance and meat quality of Xichou Wugu chicken.In a word,adding 3％Amomum tsao-ko stems and leaves to feed of Xichou Wugu chicken was much more economical and effective.
