A database containing 140 articles published in journals (731 treatment means evaluated) was used to examine the effect of different lactic acid bacteria (LAB) on fermentation, chemical composition and aerobic stability of maize (corn) silage. Compared with the control, dry matter (DM) loss increased by 8% and 50% (p < .01) due to inoculation of maize silage with either homolactic LAB (^hoLAB) or heterolactic LAB (^heLAB). In vitro DM digestibility of maize silage increased only with ^hoLAB inoculation (+2.22%; p < .01). The ^heLAB inoculation increased (p < .01) the aerobic stability of maize silage by 71.3 hr. To investigate the effect of silage inoculation on livestock production, a second database comprising 35 articles [99 treatment means evaluated based on results from 648 cattle (429 beef cattle and 219 dairy cows) and 298 sheep] was used. Inoculation of maize silage with either ^hoLAB or ^heLAB did not affect milk yield (p > .05), but their combination (^mixLAB) depressed milk yield (–2.5 kg/day; p < .01). Inoculation with ^hoLAB increased DM intake in sheep (+0.15 kg/day; p = .02), but decreased it in beef cattle (–0.26 kg/day; p = .01) without affecting average daily gain for both sheep and beef cattle (p ≥ .06). In conclusion, fermentative loss increased regardless of the bacterial inoculant used, while aerobic stability increased mainly by using ^heLAB. Benefits from ^hoLAB inoculation on animal performance were noted only for feed intake in sheep, while productive performances of dairy cows and beef cattle were not improved.

一项针对玉米青贮饲料的乳酸菌接种剂的荟萃分析：对发酵，有氧稳定性，营养价值和畜牧生产的影响

数据库中包含140篇发表在期刊上的文章（评估了731种处理手段），用于检查不同乳酸菌（LAB）对玉米（玉米）青贮饲料发酵，化学成分和需氧稳定性的影响。与对照相比， 由于用纯乳酸LAB（^ho LAB）或杂乳酸LAB（^he LAB）接种玉米青贮饲料，干物质（DM）损失增加了8％和50％（p <.01 ）。玉米青贮饲料的体外DM消化率仅通过^ho LAB接种增加（+ 2.22％; p  <.01）。在^他LAB接种增加（p <.01）玉米青贮饲料的需氧稳定性达71.3小时。为了研究青贮饲料接种对牲畜生产的影响，使用了包含35篇文章的第二个数据库[根据648头牛（429头肉牛和219头奶牛和298头绵羊的结果评估了99种处理方法）。使用^ho LAB或^he LAB接种玉米青贮饲料均不会影响产奶量（p  > .05），但二者的组合（^混合LAB）会降低产奶量（–2.5 kg /天；p  <.01）。接种^ho LAB可以增加绵羊的DM摄入量（+0.15千克/天；p  = .02），而降低肉牛的DM摄入量（–0.26千克/天；p = 0.01），而不影响平均日增重两个绵羊和肉牛（p  ≥0.06）。总之，发酵损失不管使用的细菌接种的增加，而有氧稳定性增加主要是通过^他顾。有人指出，^ho LAB接种对动物性能的好处仅在于绵羊采食饲料，而奶牛和肉牛的生产性能并未改善。
