【摘要】:為研究肉雞高溫馴化對(duì)生產(chǎn)性能及再次高溫暴露生化指標(biāo)變化的影響,本試驗(yàn)將30只21 d肉雞隨機(jī)均分為對(duì)照組、試驗(yàn)Ⅰ組和Ⅱ組。對(duì)照組標(biāo)準(zhǔn)環(huán)境溫度飼養(yǎng),試驗(yàn)Ⅰ組和Ⅱ組分別高溫(32±1)℃,6 h/d馴化1 d和3 d。1周后環(huán)境溫度升至(32±1)℃,持續(xù)6 h后翅下靜脈采血2 mL,分離血清,測(cè)定生化指標(biāo)。結(jié)果表明,與對(duì)照組相比,試驗(yàn)Ⅰ組料肉比、血清肌酐(CREA)、天門(mén)冬氨酸轉(zhuǎn)氨酶(AST)、γ-谷氨酰轉(zhuǎn)移酶(γ-GT)、葡萄糖(GLU)顯著降低(P005),試驗(yàn)Ⅱ組料肉比顯著增加(P005),體重、增重、血清AST、谷丙轉(zhuǎn)氨酶(ALT)、堿性磷酸酶(ALP)、γ-GT、尿素氮顯著降低(P005)。此外,與試驗(yàn)Ⅰ組相比,試驗(yàn)Ⅱ組的料肉比顯著增加(P005),體重、增重、ALT,ALP、GLU顯著降低(P005)。結(jié)果提示,高溫馴化影響肉雞的生產(chǎn)性能,但減少肝腎功能的損傷。
