An experiment was carried out to comparatively evaluate the effect of effective microbe (EM)- and urea molasses (UM)-treated finger millet straw (EMTFMS and UMTFMS, respectively) on nutrient utilization and growth performance of Washera lambs. Twenty yearling intact male Washera lambs with an initial body weight of 21.13 ± 1.77 kg (mean ± SE) were used for feeding and digestibility trial. These lambs were grouped into five blocks of four animals and randomly assigned to four dietary treatments. The four experimental feeds were untreated finger millet straw (control) + 150 g wheat bran (WB) (T1), untreated finger millet straw + 150 g WB + 150 g Noug seed cake (NSC) (T2), UMTFMS + 150 g WB + 150 g NSC (T3), and EMTFMS + 150 g WB + 150 g NSC (T4). The lambs were de-wormed and vaccinated against ecto- and endo-parasites. Data were analyzed using ANOVA procedure of SAS. Results showed that crude protein (CP) content of finger millet straw (FMS) was improved from 2.13 to 9.7% in UM treatment and 2.13 to 2.39% in EM treatments. Total DM, CP, and OM intake were higher in lambs assigned in UMTFMS (P < 0.01) and EMTFMS (P < 0.01) than the control groups and significantly highest (P < 0.01) in UMTFMS. A non-significant (P > 0.05) difference was observed between treatment technologies in all nutrient apparent digestibility and average daily weight gain. Therefore, it can be concluded that both treatments could serve as an alternative measure to improve nutritive value of finger millet straw, but due to environmental effect, EM treatment could be safe.
进行了一项实验,以比较评估有效微生物(EM)和尿素糖蜜(UM)处理的龙爪稷秸秆(分别为EMTFMS和UMTFMS)对瓦谢拉羔羊营养利用和生长性能的影响。选用20只初始体重为21.13±1.77千克(均值±标准误)的一岁未阉割雄性瓦谢拉羔羊进行饲养和消化试验。这些羔羊被分成五个区组,每个区组四只动物,并随机分配到四种日粮处理组。四种试验饲料分别为未处理的龙爪稷秸秆(对照)+150克麦麸(WB)(T1)、未处理的龙爪稷秸秆+150克WB+150克诺格籽饼(NSC)(T2)、UMTFMS+150克WB+150克NSC(T3)以及EMTFMS+150克WB+150克NSC(T4)。对羔羊进行了驱虫,并接种了抗外寄生虫和内寄生虫的疫苗。数据采用SAS的ANOVA程序进行分析。结果表明,UM处理使龙爪稷秸秆(FMS)的粗蛋白(CP)含量从2.13%提高到9.7%,EM处理使其从2.13%提高到2.39%。UMTFMS组(P<0.01)和EMTFMS组(P<0.01)羔羊的总干物质、CP和有机物摄入量高于对照组,且UMTFMS组显著最高(P<0.01)。在所有营养物质表观消化率和平均日增重方面观察到各处理技术之间无显著差异(P>0.05)。因此,可以得出结论,两种处理均可作为提高龙爪稷秸秆营养价值选择,但由于环境影响,EM处理可能更安全。
