【摘要】:為研究復(fù)方中草藥添加劑對肉雞肌肉生長發(fā)育的影響,試驗選用健康1日齡AA(Arbor Acres)肉雞400羽,隨機分成4組,每組5個重復(fù),每個重復(fù)20只。對照組飼喂玉米-豆粕型基礎(chǔ)日糧,試驗Ⅰ、Ⅱ和Ⅲ組分別在基礎(chǔ)日糧中添加0.5%、1.0%和1.5%的復(fù)方中草藥添加劑,試驗期42 d。在21、42日齡時將肉雞稱重屠宰,分離胸肌和腿肌進(jìn)行稱重并計算胸肌率和腿肌率,取適量肌肉組織進(jìn)行肌纖維直徑測定和組織切片制作。結(jié)果表明:與對照組相比,21日齡時,各試驗組肉雞的平均體重、平均日增重、肌肉重量與肌肉率無顯著變化(P0.05),而1.0%組肉雞的腿肌纖維直徑顯著降低(P0.05),平均日采食量和耗料增比有所降低;42日齡時,0.5%組肉雞的平均體重和平均日增重升高(P0.05),平均日采食量和耗料增比降低,其肌肉發(fā)育最好,胸肌肌肉率顯著提高(P0.05),胸肌纖維直徑顯著降低(P0.05)。以上結(jié)果表明,飼料中添加0.5%和1.0%復(fù)方中草藥添加劑可以促進(jìn)肉雞肌肉發(fā)育,提高肌肉率,降低肌纖維直徑,改善其組織結(jié)構(gòu)。
