Barley straw is a farm by product that may be useful in animal feeding but its use is limited due to its low nutritional value and high fiber content. Therefore, this study aimed to improving the nutritive value of barley straw by bacterial treatment with Condensed Molasses Soluble (CMS) in the ration of Barki lambs.
In Experiment 1, 12 Barki rams, which were divided into 3 equal groups (4 each), were given rations which consisted of 50% CFM+50%, either clover hay (C) or bacterial treated barley straw (T1) or T1+ CMS (T2). In Experiment 2, 10 Barki lambs were divided into 2 groups, one (C) and T2 as descripted in Experiment 1. Data analyzed by using one way ANOVA model.
Digestibility of Dry Matter (DM), Organic Matter (OM), Crude Fiber (CF) and Ether Extract (EE) were insignificantly affected among all rations, while Digestible Crude Protein (DCP) recorded a higher value in T2 compared to T1. Changes in Total Digestible Nutrients (TDN) values were insignificant. Values of DCP were higher for T2 compared to C and T1. The Body Weight Gain (BWG) and Feed Conversion Ratio (FCR) of growing lambs didn't statistically differ among the groups.
Finally, complete replacement of clover hay by treated barley straw plus CMS may be considered good feeding strategies in the feeding of Barki lambs in Arid and semi-arid regions.
麦草是一种农业副产品，在动物饲养中可能有用，但由于其营养价值低、纤维含量高，其用途有限。因此，本研究旨在通过细菌处理用浓缩糖蜜液（CMS）来提高大麦秸秆在 Barki 羔羊日粮中的营养价值。
在实验 1 中，将 12 只 Barki 公羊分为 3 组（每组 4 只），分别给予由 50% CFM+50%三叶草干草（C）、细菌处理的大麦秸秆（T1）或 T1+CMS（T2）组成的日粮。在实验 2 中，将 10 只 Barki 羔羊分为两组，一组（C）和 T2，如实验 1 所述。数据采用单因素方差分析模型进行分析。
所有日粮中干物质（DM）、有机物（OM）、粗纤维（CF）和乙醚提取物（EE）的消化率均无显著差异，而 T2 的可消化粗蛋白（DCP）值高于 T1。总可消化养分（TDN）值的变化不显著。T2 的 DCP 值高于 C 和 T1。生长羔羊的体重增重（BWG）和饲料转化率（FCR）在各组之间无统计学差异。
最后，用处理过的大麦秸秆加 CMS 完全替代三叶草干草可能被认为是干旱和半干旱地区 Barki 羔羊饲养的良好饲养策略。
