【摘要】：為了研究海鮮菇廢菌棒混貯發(fā)酵飼料對羔羊生長性能、屠宰性狀及肉質(zhì)的影響,確定適宜混貯比例,選擇體重相近、3月齡左右的健康波雜山羊32只,隨機(jī)分成四組,每組8只,分別飼喂含0%(對照組)、16%、32%、48%海鮮菇廢菌棒的混貯飼料,試驗(yàn)期60d。結(jié)果表明,試驗(yàn)組Ⅰ、Ⅱ、Ⅲ羔羊的日增重分別比對照組提高9.52%、19.14%和11.29%(P0.05),每只羊日均利潤分別提高0.43元、0.81元和0.69元;與對照組相比,屠宰率、凈肉率、眼肌面積等屠宰性能沒有顯著差異(P0.05);羊肉中粗脂肪含量試驗(yàn)組Ⅱ最高,比對照組高20.1%(P0.05),膽固醇含量分別比對照組降低16.6%、21.3%和27.2%(P0.05),其它營養(yǎng)成份差異不顯著(P0.05);羊肉中鈣、磷、銅、錳、硒的含量高于對照組,而鐵、鋅含量低于對照組(P0.05);羊肉中氨基酸除了絲氨酸、脯氨酸含量,試驗(yàn)組Ⅲ低于對照組;試驗(yàn)Ⅰ組纈氨酸低于對照組、蛋氨酸高于對照組外(P0.05),其它氨基酸含量差異不顯著(P0.05);油酸含量試驗(yàn)組Ⅱ、Ⅲ分別比對照組高17.3%、13.5%(P0.05),其它脂肪酸差異不顯著(P0.05)。因此,利用海鮮菇廢菌棒與糟渣類資源混貯發(fā)酵后飼喂羔羊行之有效,適宜添加比例以32%為佳。
[Abstract]:In order to study the effect of mixed fermentation feed on growth performance, slaughtering character and meat quality of lamb, 32 healthy Boza goats with similar body weight about 3 months old were selected and randomly divided into four groups, 8 in each group, in order to study the effect of mixed fermentation feed on lamb growth, slaughter characteristics and meat quality. The control group (control group) was fed with mixed feed containing 48% spent mushroom rods for 60 days. The results showed that the daily gain of lambs in group 鈪，
