摘要
为了充分利用茴香秸秆和秕壳,减少浪费及其对环境的污染,将采集的茴香秸秆、秕壳与玉米秸秆等比例混合,用不同方法处理后作为粗饲料饲喂湖羊羔羊,研究茴香秸秆和秕壳对羔羊的采食量、日增重、F/G及羊肉中脂肪酸含量的影响.结果表明,复合微生物菌系发酵处理的茴香秸秆和秕壳可显著提高育肥羊采食量、日增重,降低F/G(P＜0.05),可在一定程度上降低羊肉膻味.
Abstract
In order to make full use of fennel by-products(straw and chaff),reduce waste and environmental pollution,the fennel by-products collected were mixed with corn straw in equal proportions and treated with different methods as coarse fodder for feeding Hu sheep.It was studied and analyzed on the effects of different treatment methods on feed intake,daily gain,F/G,and fatty acid content in lamb.The results showed that there were extremely significant differences(P＜0.01)or significant differences(P＜0.05)in feed intake,daily gain and F/G between the fermentation treatment method of complex microbial straint and other treatment methods.Through the determination of fatty acid content,it was found that the flavour of mutton can be reduced to varying degrees when the lambs eat a certain amount of fennel byproducts.
