【摘要】：試驗(yàn)旨在研究添加復(fù)合型霉菌毒素脫毒劑對(duì)飼喂霉變飼料的蛋雞生產(chǎn)性能、蛋品質(zhì)和血清生化指標(biāo)的影響。將420日齡的600只海蘭褐蛋雞隨機(jī)分為5組,每組5個(gè)重復(fù),每個(gè)重復(fù)24只。空白對(duì)照組(Ⅰ組):飼喂正常玉米日糧;陰性對(duì)照組(Ⅱ組):飼喂用50%霉變玉米替代正常玉米的日糧;試驗(yàn)Ⅲ、Ⅳ和Ⅴ組,飼喂在陰性對(duì)照日糧的基礎(chǔ)上添加復(fù)合型霉菌毒素脫毒劑,添加量分別為1.0‰、2.0‰和4.0‰。結(jié)果表明:(1)與空白對(duì)照組相比,霉菌毒素顯著降低蛋雞產(chǎn)蛋率、顯著提高日耗料量、料蛋比和破軟殼率;與陰性對(duì)照霉菌毒素組相比,2.0‰和4.0‰復(fù)合型霉菌毒素吸附劑組可顯著提高蛋雞產(chǎn)蛋率、顯著降低日耗料量、破軟殼率和料蛋比,其中以4.0‰添加量組效果最優(yōu)。(2)與空白對(duì)照組相比,陰性對(duì)照飼喂霉菌毒素日糧蛋殼厚度、蛋殼強(qiáng)度和蛋黃色澤分別降低19.44%、16.29%和20.50%,差異均顯著(P0.05)。與陰性對(duì)照組相比,2.0‰和4.0‰復(fù)合霉菌毒素吸附劑添加量組蛋殼厚度分別提高20.69%和27.59%、蛋殼強(qiáng)度分別提高17.79%和15.77%、4.0‰添加量組蛋黃色澤提高19.00%,差異均顯著(P0.05)。(3)與空白對(duì)照組相比,霉菌毒素顯著提高了血清中ALT、AST和ALP含量。4.0‰復(fù)合型霉菌毒素脫毒劑組谷丙轉(zhuǎn)氨酶(ALT)、谷草轉(zhuǎn)氨酶(AST)和堿性磷酸酶(ALP)分別降低25.04%、16.19%和17.46%,差異均顯著(P0.05)。由此可知,霉變飼料中添加該復(fù)合型霉菌毒素脫毒劑能夠提高蛋雞生產(chǎn)性能、改善蛋品質(zhì)及減輕毒素對(duì)肝臟的損傷,綜合比較以試驗(yàn)Ⅴ組4.0‰添加量時(shí)效果最優(yōu)。
