An experiment was conducted to compare Horro and Washera sheep in terms of feed intake, digestibility, body weight gain and economic feasibility fed untreated wheat straw (UTWS) a basal diet and supplemented with an effective microorganism-treated wheat straw (EMTWS) and concentrate mixture (CM).
A total of 10 from each sheep breeds and 2 supplement amounts of EMTWS, supplemented at 10% (A1) and 15% (A2) of the total dry matter intake (TDMI), were arranged in a 2 × 2 factorial treatment arrangement in a completely randomized block design. The sheep of each breed were blocked on the basis of their initial body weights into five blocks of four animals in a block (two animals from each sheep breed), and treatment feeds were randomly allocated within a block during the 100 experimental days. Daily feed intake and body weight at the 10-day interval were recorded, and data were analysed using general linear model procedures (PROC GLM) of SAS software program.
The crude protein (CP) content of EMTWS showed only a 1% increment over UTWS, whereas its neutral detergent fibre (NDF) and acid detergent fibre (ADF) values showed a 10% reduction over UTWS. Washera sheep consumed 40 g more TDM over Horro sheep. Sheep fed the A2 supplement consumed 86 g more (p < 0.0001) TDM over A1-fed sheep. Consequently, Washera sheep and sheep fed-A2 gained 1 and 3 kg of additional body weight by growing 11 g/day and 33 g over Horro sheep and those sheep fed-A1, respectively. Sheep fed-A2 and Washera sheep gave better economic returns than A1-fed sheep and Horro sheep, respectively.
Therefore, from the results of the study, it could be suggested that rearing Washera sheep by supplementing 15% EMTWS along with a CM can be recommended for smallholder farmers.
开展了一项实验，比较霍罗羊和瓦谢拉羊在以未处理小麦秸秆（UTWS）为基础日粮并补充有效微生物处理小麦秸秆（EMTWS）和精料混合料（CM）的情况下，在采食量、消化率、体重增加和经济可行性方面的表现。
每个绵羊品种各选10只，以及两种EMTWS补充量，分别按总干物质摄入量（TDMI）的10%（A1）和15%（A2）进行补充，采用2×2析因处理安排，进行完全随机区组设计。每个品种的绵羊根据其初始体重分为五个区组，每个区组四只动物（每个绵羊品种两只），在100天的实验期内，处理饲料在区组内随机分配。每隔10天记录每日采食量和体重，并使用SAS软件程序的通用线性模型程序（PROC GLM）分析数据。
EMTWS的粗蛋白（CP）含量仅比UTWS高1%，而其中性洗涤纤维（NDF）和酸性洗涤纤维（ADF）值比UTWS低10%。瓦谢拉羊比霍罗羊多消耗40克总可消化养分（TDM）。饲喂A2补充料的绵羊比饲喂A1补充料的绵羊多消耗86克TDM（p<0.0001）。因此，瓦谢拉羊和饲喂A2的绵羊分别比霍罗羊和饲喂A1的绵羊每天多增重11克和33克，体重额外增加1千克和3千克。饲喂A2的绵羊和瓦谢拉羊分别比饲喂A1的绵羊和霍罗羊获得更好的经济效益。
因此，从研究结果可以建议，对于小农户来说，推荐饲养瓦谢拉羊，并补充15%的EMTWS和CM。
