粗饲料在维持反刍动物健康和提高生产性能方面起着重要作用。粗饲料经瘤胃内的微生物发酵降解为可吸收利用的物质,可以维持机体的正常生命活动。粗饲料通过刺激动物反刍、唾液分泌和瘤胃发育可以维持瘤胃健康。粗饲料摄入量不足会导致反刍动物胃肠道损伤、营养缺乏、生产性能下降以及行为异常等问题。不同粗饲料的组织结构和营养组分差异会影响反刍动物的营养消化、能氮利用及机体代谢等。因此,饲粮中不同粗饲料来源是影响瘤胃功能和生产性能的关键因素。文章综述了不同来源粗饲料的品质及其对反刍动物瘤胃微生物、机体代谢和生产性能的影响,并对其作用机制进行阐述,为粗饲料在反刍动物中的合理利用提供参考。

Alkali stress can cause severe crop damage and reduce production. However, physiological processes involved in alkali stress in oat seedlings are not well understood. In this study, physiological responses and yield of oat to alkali stress were studied using the alkali-tolerant oat genotype Vao-9 and the alkali-sensitive oat genotype Baiyan 5. The results were：（i） low concentrations of alkali stress （25 and 50 mmol L^-1） significantly reduced the yield and grain weight while increased the oat grain number per spike. A negative correlation between yield and malondialdehyde （MDA） content at the jointing and grain filling stages and positive correlations between yield on one hand and superoxide dismutase （SOD）, and peroxidase （POD） activities on the other at the jointing stage were observed. There was a positive correlation between MDA and soluble sugar at the grain filling stage; （ii） soluble sugar content was increased at the jointing and grain filling stages and decreased at the heading stage by alkali stress; （iii） alkali stress increased the SOD activity during the heading and grain filling stages, and increased the POD activity at the heading stage. As compared to the control, the increase of MDA contents in alkali-treated oat was observed, during the jointing, heading and grain filling stages; （iv） under alkali stress, the oat genotype Vao-9 showed higher antioxidant enzyme activity and lower soluble sugar contents during the heading stage, and lower MDA contents than those in the oat genotype Baiyan 5 under alkali stress. The result suggested that the high ROS scavenging capacity and soluble sugar levels might play roles in oat response to alkali stress,

金属连接体产生的含铬蒸气使固体氧化物燃料电池(SOFC)的阴极性能发生快速衰减,是SOFC电堆的主要衰减机制之一。通过在la_(0.6)Sr_(0.4)Co_(0.2)Fe_(0.8)O_(3-δ)(LSCF)阴极上修饰Ba CeO_(3)(BCO)纳米颗粒,有效提高了阴极的电催化活性和在加速铬中毒条件下的运行稳定性。BCO颗粒既能抑制LSCF表面Sr偏析,又能优先与连接体表面的Cr_(2)O_(3)发生反应,在电极表面生成导电的BaCrO_(4)阻挡层,隔绝了阴极与连接体的直接接触,避免了SrCrO_(4)的生成。这两个因素的协同作用显著增强了BCO-LSCF阴极的耐铬毒化性能。
