Abstract

Background and Objectives: Improving ruminant environmental impacts and productivity get a great interest in last years, herbal plants were investigated as feed additive for decreasing gas production from rumen and enhancing nutrients digestibility. So, in the current study was carried out to investigate the effect of supplementing ruminant diets with different levels of thyme or celery on rumen fermentation, digestibility and gas production. Materials and Methods: Seven experimental treatments were done using rumen in vitro batch culture technique. Treatments were: 60% CFM, 40% clover hay (control), control diet+5 g thyme kgG1 DM (T1), control diet+10 g thyme kgG1 DM (T2), control diet+20 g thyme kgG1 DM (T3), control diet+5 gG1 celery kgG1 DM (T4), control diet+10 gG1 celery kgG1 DM (T5), control diet+20 g celery kgG1 DM (T6), control diet+0.4 g salinomycin kgG1 DM (T7). Results: The obtained results showed no significant (p>0.05) change in ruminal pH, neutral detergent fiber (NDF) and acid detergent fiber (ADF) degradation. Thyme addition to diet (T1 and T2) significantly lowered (p<0.05) total gas production (TGP) compared with control (152, 152 vs. 157 mL, respectively). Dry matter and organic matter disappearance (DMd, OMd) appeared showed no significant difference (p<0.05) between control and thyme treatments (T1, T2 and T3) and celery treatments (T4, T5 and T6). Conclusion: It could be concluded the adding thyme or celery at low levels to ruminant diets could improve ruminal fermentation and reducing gas production without adverse effect on nutrients digestibility.

芹菜和百里香作为瘤胃发酵消化率调节剂及减气量的研究
背景与目的:近年来,人们对改善反刍动物环境影响和提高生产效率的研究日益受到关注,草药植物作为饲料添加剂被研究用于降低瘤胃产气量和提高营养物质消化率。因此,本试验旨在探讨在反刍动物饲粮中添加不同水平百里香或芹菜对瘤胃发酵、消化率和产气量的影响。材料与方法:采用瘤胃体外批培养技术进行7个试验处理。处理为:60% CFM、40%苜蓿干草(对照)、对照日粮+5 g百里香kgG1 DM (T1)、对照日粮+10 g百里香kgG1 DM (T2)、对照日粮+20 g百里香kgG1 DM (T3)、对照日粮+5 g芹菜kgG1 DM (T4)、对照日粮+10 g芹菜kgG1 DM (T5)、对照日粮+20 g芹菜kgG1 DM (T6)、对照日粮+0.4 g盐霉素kgG1 DM (T7)。结果:试验结果显示,瘤胃pH、中性洗涤纤维(NDF)和酸性洗涤纤维(ADF)降解无显著(p>0.05)变化。饲粮中添加百里香(T1和T2)显著降低了总产气量(TGP)(分别为152、152和157 mL) (p<0.05)。干物质和有机质消失量(DMd、OMd)在对照、百里香处理(T1、T2和T3)和芹菜处理(T4、T5和T6)之间无显著差异(p<0.05)。结论:在反刍动物日粮中添加低水平百里香或芹菜可促进瘤胃发酵,降低产气量,但不影响营养物质消化率。
