Is It Possible to Improve the Fermentation and Nutritional Quality of Wheat Straw Silage by Replacing Commercial Inoculant with Kefir?

The current study aimed to determine fermentation quality, aerobic stability, and enzyme soluble organic matter (ELOS) of wheat straw silage by replacing homofermentative (HM) homofermentative+heterofermentative (HM+HT) lactic acid bacteria (LAB) inoculants with kefir as additives. For this purpose, commercially available Biotal Plus II (HMLAB), Buchneri 500 (HM+HTLAB), MYStarter KF (KF) were used Four kg straw, about 400 g/kg, 6.0 log cfu or in each treatment group replicate. Including the control (CON), a total 12 laboratory-type silos (3 replicates 4 groups) opened after 45 days. dry (DM), crude ash (CA), detergent lignin (ADL), water-soluble carbohydrate contents silages not affected addition HMLAB, HM+HTLAB, (P>0.05). had lowest pH value (4.32), NH3-N content (71.97 g/kg TN), higher (43.11 DM). protein (CP) ratio was decreased HMLAB (5.95%) HM+HTLAB (5.63%) groups increased (4.54%, P<0.001). An improvement (by lowering 17.02%) NDF only observed (P<0.001). ELOS ME carbon dioxide (3.42 DM) yeast (5.50 log10 cfu/g) CON group, respectively. According research findings, could be an alternative additive improve silage’s nutritional quality instead them.
