1、2015年第36卷第15期總第492期SILIAOGONGYE多功能復(fù)合菌劑發(fā)酵玉米秸稈粉營(yíng)養(yǎng)成分分析及其對(duì)育肥豬的飼喂效果111211■李術(shù)娜李紅亞劉利徐麗娜王全朱寶成(1.河北農(nóng)業(yè)大學(xué)生命科學(xué)學(xué)院,河北保定071001;2.河北工程大學(xué),河北邯鄲056038)摘要:分析多功能復(fù)合菌劑發(fā)酵后的玉米秸稈粉營(yíng)養(yǎng)成分變化,并考察其替代飼糧對(duì)育肥豬的增重效果,探討發(fā)酵玉米秸稈用于育肥豬養(yǎng)殖的可行性。制備發(fā)酵玉米秸稈粉,并委托農(nóng)業(yè)部飼料效價(jià)與安全監(jiān)督檢驗(yàn)測(cè)試中心對(duì)其進(jìn)行常規(guī)營(yíng)養(yǎng)成分分析。以大白×長(zhǎng)白×杜洛克三元雜交豬為供試豬,分為3組,對(duì)照組飼喂常規(guī)飼糧,試驗(yàn)組Ⅰ飼喂
2、90%常規(guī)飼糧+10%發(fā)酵玉米秸稈粉,試驗(yàn)組Ⅱ飼喂80%常規(guī)飼糧+20%發(fā)酵玉米秸稈粉,試驗(yàn)組Ⅲ飼喂75%常規(guī)飼糧+25%發(fā)酵玉米秸稈粉,測(cè)定并計(jì)算供試豬的料肉比與增重成本。結(jié)果表明:①發(fā)酵玉米秸稈粉營(yíng)養(yǎng)價(jià)值相比發(fā)酵前顯著提升。②相比對(duì)照組,試驗(yàn)組Ⅰ、Ⅱ料肉比分別下降8.06%(P<0.01)與1.73%(P<0.05),試驗(yàn)組Ⅲ料肉比提高10.29%(P<0.01);試驗(yàn)Ⅰ、Ⅱ、Ⅲ組飼料價(jià)格比常規(guī)日糧下降6.73%、13.13%與17.51%,增重成本分別降低14.10%和14.75%與8.93%。發(fā)酵玉米秸稈粉作為一種新型的粗飼料,其飼用價(jià)值大大提高,可作
3、為一種新型優(yōu)質(zhì)高替代飼料應(yīng)用于育肥豬生產(chǎn)中。在生豬日糧中替代10%的發(fā)酵玉米秸稈粉,可促進(jìn)試豬對(duì)營(yíng)養(yǎng)物質(zhì)的消化吸收,顯著降低料肉比與增重成本,提高養(yǎng)殖效益。關(guān)鍵詞:多功能復(fù)合菌劑;發(fā)酵玉米秸稈;營(yíng)養(yǎng)成分;育肥豬;飼喂效果doi:10.13302/j.cnki.fi.2015.15.007中圖分類號(hào):S816.32文獻(xiàn)標(biāo)識(shí)碼:A文章編號(hào):1001-991X(2015)15-0027-05Nutrientlevelofmultifunctionalcompositeagentsfermentedcornstrawanditsfeedingeffectstofate
