【摘要】：為探討益生菌和酶制劑對(duì)秸稈利用率的影響,本試驗(yàn)以水稻秸稈和小麥秸稈為粗飼料原料,采用添加菌酶復(fù)合制劑將秸稈進(jìn)行發(fā)酵后制作混合日糧及在混合日糧中直接加入復(fù)合酶制劑兩種生物處理方式進(jìn)行肉羊飼喂試驗(yàn),旨在為水稻和小麥秸稈的有效利用提供理論依據(jù)。本試驗(yàn)分兩部分進(jìn)行,具體內(nèi)容如下:試驗(yàn)一:本試驗(yàn)研究益生菌與酶混合制劑及復(fù)合酶制劑處理的水稻秸稈,對(duì)肉用綿羊生長(zhǎng)性能、養(yǎng)分消化率、屠宰性能及血清生化指標(biāo)的影響,目的是為了探索出高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,分別采取不同的飼喂處理,每個(gè)處理5個(gè)重復(fù),每個(gè)重復(fù)4只�？瞻讓�(duì)照組(干水稻秸稈)、處理組Ⅰ(水稻秸稈添加菌酶復(fù)合制劑)、處理組Ⅱ(干水稻秸稈添加復(fù)合酶制劑)、羊草對(duì)照組,8天預(yù)飼期,60天正試期。結(jié)果表明:處理組Ⅰ、Ⅱ與羊草對(duì)照組試驗(yàn)羊干物質(zhì)采食量、平均日增重和飼料轉(zhuǎn)化效率均顯著高于空白對(duì)照組(P0.05),處理組Ⅰ、Ⅱ與羊草對(duì)照組三組之間差異不顯著(P0.05);處理組Ⅰ試驗(yàn)羊干物質(zhì)(Dry Matter,DM)、有機(jī)物(Organic Matter,OM)、中性洗滌纖維(Neutral Detergent Fibre,NDF)和酸性洗滌物質(zhì)(Acid Detergent Fiber,ADF)的消化率顯著高于空白對(duì)照組(P0.05),除NDF消化率外,其他指標(biāo)均與羊草對(duì)照組差異不顯著(P0.05),處理組Ⅱ試驗(yàn)羊DM、NDF和ADF的消化率顯著高于空白對(duì)照組(P0.05),但與羊草對(duì)照組之間差異不顯著(P0.05),Ⅰ、Ⅱ處理組組間差異不顯著(P0.05);不同處理組屠宰率無(wú)顯著差異(P0.05);頭、蹄和皮+毛重量4個(gè)組組間無(wú)顯著性差異(P0.05);消化器官中,空白對(duì)照組肝臟和瘤胃重量均顯著低于Ⅰ、Ⅱ處理組(P0.05),剩余組織器官、胃室、小腸和大腸重量和占宰前活重的比例各組之間差異不顯著(P0.05);試驗(yàn)羊血清生化指標(biāo)各組之間差異不顯著(P0.05)。因此,合理的菌酶配伍對(duì)水稻秸稈有顯著的改善作用,可以提高水稻秸稈營(yíng)養(yǎng)物質(zhì)的消化率,接近羊草的飼喂效果;酶制劑的合理組合有利于促進(jìn)營(yíng)養(yǎng)物質(zhì)的消化利用,效果達(dá)到或超過(guò)羊草水平。試驗(yàn)二:本試驗(yàn)旨在研究益生菌與酶混合制劑和復(fù)合酶制劑處理的小麥秸稈,對(duì)肉用綿羊生長(zhǎng)性能、養(yǎng)分消化率、屠宰性能及血清生化指標(biāo)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)組分別進(jìn)行不同的飼喂處理,每個(gè)處理5個(gè)重復(fù),每個(gè)重復(fù)4只�？瞻讓�(duì)照組(干小麥秸稈)、處理組Ⅰ(小麥秸稈添加菌酶復(fù)合制劑)、處理組Ⅱ(干小麥秸稈添加復(fù)合酶制劑)、羊草對(duì)照組,預(yù)飼期8天,正試期為60天。結(jié)果表明:處理組Ⅰ、Ⅱ與羊草對(duì)照組試驗(yàn)羊平均日增重和料重比均顯著高于空白對(duì)照組(P0.05),Ⅰ、Ⅱ處理組與羊草對(duì)照組組間差異不顯著(P0.05);DM和OM的消化率處理組與對(duì)照組各組之間差異不顯著(P0.05),處理組Ⅰ試驗(yàn)羊NDF的消化率顯著高于空白對(duì)照組(P0.05),但與羊草對(duì)照組相比差異不顯著(P0.05),處理組Ⅱ試驗(yàn)羊NDF的消化率與兩組對(duì)照組相比差異均不顯著(P0.05),處理組Ⅰ和羊草對(duì)照組ADF的消化率顯著高于空白對(duì)照組(P0.05),處理組ⅡADF的消化率與空白對(duì)照組相比差異不顯著(P0.05);不同處理組屠宰率無(wú)顯著差異(P0.05);頭、蹄和皮+毛重量4個(gè)組組間無(wú)顯著差異(P0.05);消化器官中,空白對(duì)照組肝臟的重量顯著低于試驗(yàn)組(P0.05),剩余組織器官、胃室、小腸和大腸重量和占宰前活重的比例各組之間差異不顯著(P0.05);試驗(yàn)羊血清生化指標(biāo)四組之間差異不顯著(P0.05)。因此,合理的菌酶配伍對(duì)小麥秸稈有顯著的改善作用,可以提高小麥秸稈營(yíng)養(yǎng)物質(zhì)的消化率,接近羊草的飼喂效果;酶制劑的合理組合有利于促進(jìn)營(yíng)養(yǎng)物質(zhì)的消化利用,效果達(dá)到或超過(guò)羊草水平。綜上所述,水稻和小麥秸稈經(jīng)過(guò)兩種生物制劑處理后,均顯著改善了秸稈的發(fā)酵品質(zhì),提高了試驗(yàn)羊的生長(zhǎng)性能與其對(duì)秸稈營(yíng)養(yǎng)物質(zhì)的消化率,對(duì)血清生化指標(biāo)沒(méi)有產(chǎn)生不良影響,飼喂效果達(dá)到或者超過(guò)羊草水平,可以替代羊草。
[Abstract]:In ord to study that effect of the probiotics and the enzyme preparation on the utilization rate of the straw, in that invention, a mixed day grain and a compound enzyme preparation are directly adde into the mixed daily grain to carry out the feeding experiment of the meat sheep by the addition of the compound preparation of the bacterial enzyme, and the aim of the invention is to provide a theoretical foundation for the effective utilization of the rice and the wheat straw. The test is divided into two parts, and the specific content is as follows: 1. The test is conducted to study the effect of the probiotics and the enzyme mixed preparation and the composite enzyme preparation on the growth performance, the nutrient digestibility, the slaughter performance and the serum biochemical indexes of the meat sheep. the aim of the invention is to explore a high-efficiency biological preparation method. A single-factor experiment was used to design 80 male lambs with a weight of (24.00, 2.42) kg, which were randomly divided into 4 groups. Blank control group (dry rice straw), treatment group I (rice straw adding bacteria enzyme composite preparation), treatment group II (dry rice straw adding complex enzyme preparation), Leymus chinensis control group, 8-day pre-feeding period and 60-day positive test period. The results showed that the average daily weight gain and the feed conversion efficiency were significantly higher than that of the control group (P0.05), and the difference between the treatment group 鈪，
