Ruminal fermentation of sheep fed corn silage inoculated with mierobial additives

摘要

An obligatory hetcrofermcntative lactic acid bacteria (LAB); Lactobacillus buchneri, has been suggested as an additive to improve the aerobic stability of silages, mainly of corn silage, due to troubles during feedout of silos, when mishandled. Usually, heterolactic fermentation is deemed as undesirable compared with homolactic fermentation because the dry matter losses are greater. Otherwise, L. plantarum, a homo-fermentative LAB can be combined with L. buchneri in an attempt to decrease the fermentation losses and also protein degradation by greater production of lactate and, enhance the aerobic stability of silages. Nowadays, these LAB have been studied as their ability to change ruminal fermentation, well as to provide a probiotic effect. Thus,the aim was to evaluate the ruminal fermentation of sheep fed corn silage inoculated with L. buchneri alone or combined with L. plantarum.
