【摘要】：本試驗(yàn)旨在研究杏鮑菇菌糠作為發(fā)酵床墊料對發(fā)酵床溫度、斷奶仔豬生長性能、腹瀉率和消化酶活性的影響。選擇120頭體重8.0±0.5kg的"杜長大"三元雜交斷奶仔豬,隨機(jī)分為5組,對照組:50%鋸末+50%稻殼;試驗(yàn)組Ⅰ:100%菌糠;試驗(yàn)組Ⅱ:15%鋸末+15%稻殼+70%菌糠;試驗(yàn)組Ⅲ:25%鋸末+25%稻殼+50%菌糠;試驗(yàn)組Ⅳ:35%鋸末+35%稻殼+30%菌糠。結(jié)果表明,試驗(yàn)組發(fā)酵床表面溫度與對照組相比,差異不顯著(P0.05);試驗(yàn)組Ⅰ、Ⅱ和Ⅲ發(fā)酵床下20cm處溫度明顯升高(P0.05);除試驗(yàn)組Ⅳ外,其余各組與對照組相比,斷奶仔豬平均日增重明顯增加(P0.05);試驗(yàn)組Ⅰ平均日采食量明顯增加(P0.05);試驗(yàn)組Ⅱ、Ⅲ和Ⅳ與對照組相比,均顯著降低了斷奶仔豬的腹瀉率和死亡率(P0.05);與對照組相比,除試驗(yàn)組Ⅳ外,試驗(yàn)組Ⅰ、Ⅱ和Ⅲ均顯著提高了斷奶仔豬十二指腸內(nèi)容物脂肪酶和胰蛋白酶的活性(P0.05)。提示菌糠可作為發(fā)酵床墊料,促進(jìn)仔豬生長,降低養(yǎng)殖成本,試驗(yàn)組Ⅲ是最佳的墊料配比。
