1、黑龍江畜牧獸醫(yī)科技版1蛋氨酸銅對肉雞生長性能及某些生理生化指標的影響122222王榮梅,蘇榮勝,曹華斌,李和平,李成梅,唐兆新(1.韶關(guān)學(xué)院英東生物工程學(xué)院農(nóng)業(yè)科學(xué)系,廣東韶關(guān)512005;2.華南農(nóng)業(yè)大學(xué)獸醫(yī)學(xué)院,廣東廣州510642)中圖分類號:S816.71文獻標識碼:A文章編號:10047034(2009)03-0001-03關(guān)鍵詞:蛋氨酸銅;肉仔雞;生長性能;血液參數(shù)摘要:選擇1日齡健康A(chǔ)A肉仔雞120只,隨機分成4組,使用蛋氨酸銅作為銅源,對照組基礎(chǔ)日糧銅含
2、量為11mg/kg,3個試驗組日糧中銅含量分別為110mg/kg、220mg/kg和330mg/kg,各試驗組肉仔雞均飼喂添加蛋氨酸銅的玉米-豆餅型日糧至60日齡結(jié)束試驗。在12,24,36,48,60日齡稱量各組雞體重并計算出36,60日齡時的料肉比;在12,36,60日齡采血,進行紅細胞數(shù)、血紅蛋白含量及血清GH、T3、T4水平的測定。結(jié)果表明:與對照組相比,日糧中含銅110mg/kg、220mg/kg和330mg/kg對雛雞生長有明顯的促進作用(P<0.05),料肉比稍有提高,但與對照組差異不顯著(P>0.05);血
3、液紅細胞數(shù)和血紅蛋白含量都在正常范圍內(nèi),沒有出現(xiàn)異常減少;高銅(110mg/kg、220mg/kg和330mg/kg)組雞血清GH水平均低于對照組,而T3、T4濃度均顯著高于對照組(P<0.05)。結(jié)果說明高銅可促進肉雞生長,影響血清中與生長有關(guān)的激素水平。Effectsofcoppermethionineongrowthperformanceandsomebloodphysiological-biochemicalindicesinbroiler122WANGRong-mei,SURong-sheng,TANGZhao-
