目的:利用玉米油富含亚油酸和其他必需脂肪酸的特性,将其作为反刍动物日粮脂肪酸补充料有利于瘤胃微生物代谢和抑制甲烷气体排放。本试验主要研究玉米油在以下方面的潜在影响:基于总消化率的瘤胃发酵、总挥发性脂肪酸、干物质消化率、有机质消化率和养分降解率;胃肠道甲烷排放,瘤胃溶解氢和溶解甲烷。方法:选取6只健康的6月龄去势浏阳黑山羊(平均体重19 kg)。精/粗饲料比例50:50(DM基础,2%BW),处理组添加3%玉米油(100%浓缩玉米油,金龙鱼,PSN GB191,丰益制造公司,武汉粮油有限责任公司)。交叉试验设计,试验期60天。分为两组,t.组饲喂精料B(98.33%DM、15.82%CP、15.82%EE、16.30 MJ/kg、42.67%NDF、6.95%ADF、3.08%,ADL、7.56%Ash、92.56%ODM和22.8%St.rch)并添加3%玉米油和干稻草(99.17%DM、99.17%CP、99.17%EE、15.99 MJ/kg、74.44%NDF、45.83%ADF、28.61%ADL、10.19%Ash、89.89%ODM、和0.64%St.rch);t.组饲喂精料A(97.95%DM、16.28%CP、1.01%EE、16.32 MJ/kg、44.59%NDF、7.06%ADF、3.96%ADL、7.90%Ash、92.26%ODM、和24.2%St.rch)和干稻草。在研究过程中,精料、稻草、玉米油、粪便和尿液均采集样品用于测定饲料消化率。分别于饲喂后0小时、2.5小时、6小时采集瘤胃液,并利用气相色谱(安捷伦7890 A,安捷伦科技,圣克拉拉市,加州,美国)测定t.FA,NH,dH和dCH水平。山羊CH排放通过呼吸代谢仓测定,用温室气体分析仪(UGGA,NO.915-0011,LGR公司,圣何塞,加州,美国)监测24小时CH气体排放量。使用IBM SPSS 19.0软件线性混合模型进行统计分析,当Pt.FA浓度;其乙酸、丙酸、丁酸、t.FA浓度,乙丙比和Ac/t.FA显著高于对照组,同时降低Pro/t.FA和IsoV/t.FA(P<0.05)。玉米油处理组抑制了山羊的CH排放,两组间基于采食量、食入总能、代谢能计算的CH排放显示极显著差异(P<0.01);同时,玉米油处理组显著降低了总能摄入量(GEI)和中性洗涤纤维摄入量(NDFI)(P<0.05)。玉米油处理组显著增加NH浓度(P<0.05)。与对照组相比,玉米油处理组显著降低了提取气体的体积、pH值、瘤胃中dH和dCH(P<0.01)。同时,两组之间生产性能无显著差异,对体增重无影响。结论:在本研究中,玉米油的添加使瘤胃液中总挥发性脂肪酸和丙酸比例增加,NH浓度下降。因此,玉米油的添加被认为是具有一定正面效果的。玉米油倾向于减少乙酸和增加丁酸比例,并不减少总挥发性脂肪酸浓度。本研究中总挥发性脂肪酸浓度和挥发性脂肪酸组分表明,玉米油对发酵的影响取决于补充玉米油的剂量并对挥发性脂肪酸各组分作用不一致。

Object.ves: Bedaquiline (BDQ) is t.e first.new ant.-t.berculosis (t.) drug int.oduced t. t.e market.aft.r 45 years. Recent.st.dies have shown t.e pot.nt.al benefit. of adding bedaquiline t. regimens for drug-resist.nt.t. (DR-t.). In search of more effect.ve regimens for DR-t., bedaquiline was int.oduced in t.e t. program in t.e Philippines under operat.onal research t. assess it. effect.veness, safet., and t.lerabilit. when given wit. background regimens among pat.ent. wit. mult.-or ext.nsively DR-t.

Demographic dat., presence of comorbidit.es, and microbiologic profile on ent.y were recorded. Bedaquiline was administ.red at.t.e recommended dose of 400 mg once daily for 14 days, t.en 200 mg t.ree t.mes a week for 22 weeks t.get.er wit. World Healt.
