【摘要】：本試驗(yàn)研究了不同生物處理水稻秸稈對(duì)肉用綿羊生長(zhǎng)性能、屠宰性能及器官發(fā)育的影響,旨在探索有效的生物制劑處理方法。采用單因素試驗(yàn)設(shè)計(jì),選取體重為(24.00±2.42)kg的"杜泊×小尾寒羊"雜交F1代公羔羊80只,隨機(jī)分為4個(gè)組,分別為空白對(duì)照組(飼喂水稻秸稈飼糧)、Ⅰ組(飼喂細(xì)菌、酶復(fù)合青貯制劑處理的水稻秸稈飼糧)、Ⅱ組(飼喂復(fù)合酶制劑處理的水稻秸稈飼糧)、羊草對(duì)照組(飼喂羊草飼糧),每組5個(gè)重復(fù),每個(gè)重復(fù)4只羊。預(yù)試期為8d,正試期為60 d。結(jié)果表明:Ⅰ組、Ⅱ組和羊草對(duì)照組試驗(yàn)羊平均日增重和干物質(zhì)采食量均顯著高于空白對(duì)照組(P0.05),料重比顯著低于空白對(duì)照組(P0.05),但Ⅰ組、Ⅱ組和羊草對(duì)照組之間差異不顯著(P0.05)。各組間試驗(yàn)羊屠宰率無(wú)顯著差異(P0.05),各組間試驗(yàn)羊頭、蹄、皮+毛、肺臟、腎臟、網(wǎng)胃、瓣胃、皺胃、小腸和大腸的重量及其占宰前活重比例無(wú)顯著差異(P0.05),Ⅰ組、Ⅱ組和羊草對(duì)照組試驗(yàn)羊肝臟和瘤胃重量顯著高于空白對(duì)照組(P0.05)。由此可見(jiàn),細(xì)菌、酶復(fù)合青貯制劑處理水稻秸稈有顯著的改善作用,肉用綿羊的生長(zhǎng)性能、屠宰性能及器官發(fā)育接近羊草的飼喂效果。
[Abstract]:The effects of different biological treatments on growth performance, slaughtering performance and organ development of meat sheep were studied. A total of 80 crossbred F1 lambs with weight of 24.00 鹵2.42)kg were randomly divided into four groups: control group (fed with rice straw diet, group I), and control group (fed with bacteria), the control group was divided into two groups: the control group, the control group, the control group, the control group, the control group, the control group, the control group and the control group. The rice straw diet treated with enzyme compound silage, group 鈪，
