Lentilactobacillus buchneri Preactivation Affects the Mitigation of Methane Emission in Corn Silage Treated with or without Urea

The aim of this study was to investigate the effect different forms Lentilactobacillus buchneri on in vitro methane production, fermentation characteristics, nutritional quality, and aerobic stability corn silage treated with or without urea. following treatments were applied prior ensiling: (1) no urea treatment LB; (2) treatment+freeze dried (3) treatment+preactivated (4) treatment+no (5) (6) treatment+preactivated. LB at a rate 3 × 108 cfu/kg fresh basis, while 1% basis dry matter. Data measured time points analyzed according completely randomized design, 2 5 factorial arrangement treatments, others arrangement. Preactivated more effective than freeze-dried reducing pH, ammonia nitrogen, cell-wall components, yeast count, carbon dioxide as well increasing lactic acid residual water-soluble carbohydrate (p < 0.0001). A significant reduction ratio observed after 24 h 48 incubation preactivated 0.001). results indicated that combined improved reduced silages.
