Effects of Amomum tsao-ko stems and leaves on growth performance,serum indexes and meat quality of Xichou Wugu chicken
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.
