摘  要：
本试验旨在研究不同比例青稞秸秆替代苇状羊茅对全混合日粮青贮早期发酵品质及有氧稳定性的影响。试验设对照组(TH0)和3个青稞秸秆不同比例替代组TH5、TH10和TH15。青贮14 d开窖取样,分析其发酵品质、化学成分及微生物数量,将剩余的发酵TMR暴露于空气,用多通道温度记录仪记录温度变化;并分别在有氧暴露的第2、5和8天取样评定其有氧稳定性。结果表明,与对照组(TH0)相比,TH5的pH、乳酸、乙酸、总挥发性脂肪酸和乙醇含量无显著(P>0.05)差异;TH10和对照相比pH差异不显著(P>0.05),但乳酸、乙酸、总挥发性脂肪酸和乙醇含量显著(P<0.05)低于对照组;TH15 pH显著(P<0.05)高于对照组,乳酸、乙酸、总挥发性脂肪酸和乙醇含量显著(P<0.05)低于对照组;各组氨态氮/总氮和乳酸/乙酸无显著(P>0.05)差异,均以乳酸发酵为主,发酵品质良好。有氧暴露第2天后各组pH和氨态氮/总氮持续上升;乳酸、乙酸和水溶性碳水化合物含量持续下降;酵母菌和好氧细菌数量显著(P<0.05)升高。除TH15外,其他各组温度在第35 h开始上升,TH15温度上升延迟,并且温度上升峰值最小。和其他组相比,TH15有氧稳定性最好。综合考虑发酵品质、有氧稳定性及对青稞秸秆资源的最大化利用,建议采用TH15设计配方最为适宜。

摘  要：
The objective of this study was to evaluate the effects of substituting hulless barley straw for tall fescue at different ratios on early fermentation quality and aerobic stability of total mixed ration silage in Tibet. The experiment treatments were as follows: control(TH0) and three treatments(TH5,TH10 and TH15). These silos were opened on 14 days after ensiling and the fermentation quality,chemical and microbial compositions were analyzed. Meanwhile,the aerobic stability was tested by the online multi-channel data logger temperature recorder,and we took samples to estimate the aerobic stability at the 2th,5th and 8th day of exposure to air. The results showed that the pH,lactic acid,acetic acid,TVFAs and alcohol contents of TH5 had no significant(P>0.05) difference comparing with TH0. The pH of TH10 was similar( P >0.05) with TH0,but the lactic acid,acetic acid,TVFAs and alcohol contents had significant(P<0.05) difference comparing with TH0. The lactic acid,acetic acid,propionic acid,butyric acid,total volatile fatty acids and alcohol contents of TH15 were significantly( P <0.05) lower than TH0 and pH of it was markedly higher( P <0.05) than that of TH0. Ammonia nitrogen/total nitrogen and lactic acid/acetic acid had no significant(P>0.05) difference in all treatments and control. The lactic?acid?fermentation was dominant in all silages and they all had a good fermentation quality. During exposure to air,pH and ammonia nitrogen/total nitrogen in all treatments and control kept elevating after the 2th day of exposure to air,however,lactic acid,acetic acid and water soluble carbohydrates content kept decreasing; the numbers of yeast and aerobic bacteria had rising tend. Apart from TH15,other treatments temperatures began to rise at 35 h after opening the silos,TH15 delayed the rising of temperature and had the smallest peak.Bringing what had been discussed into a conclusion,TH15 had the best aerobic stability. Taking all aspects into account,including fermentation quality,aerobic stability and maximum using hulless barley straw,it was suggested that TH15 treatment was the most suitable choice.
