Envestigation of addiing different levels of bacterial inoculant (Lactobacillus plantarum) when preparing common reed silage and comparing it with corn silage

Document Type : Nutrition



This study was conducted to investigat the effect of different levels of addition of lactobacillus plantarum inoculant of common reed silage and also to compare this silage with corn silage in a compeletly randomized design with 8 treatments and 4 replication. Treatments included of common reed silage without inoculation, common reed silage with bacterial inoculation (2.5 mg/kg DM) and other treatments were inoculants silages with addition bacteria in 25, 50, 75 and 100 percent above of commercial amount, respectively and corn silage with or without bacterial inoculation (2.5 and 0 mg/kg DM). Inoculated common reed silage and corn silage were ensiled in laboratory silos (2-L- plastic jars). At the end of ensilage duration and sampeling of silge, laboratory analysis included pH, DM, CP, IVDMD, IVOMD and VFA's of silages were down. Results of this experiment indicated that inoculants of common reed silage with different levels of lactobacillus bacteria had significant effect on pH, ash and In vitro digestibility (p<0.05) but did not influence CP and VFA's (p>0.05). Inoculation of corn silage did not influence pH, CP, In vitro digestibility, propionic acid and butyric acid (p>0.05) but it had significant effect on ash and acetic acid of silages (p<0.05). According to results of experiment and considering studied factors and the inoculation influences on In vitro digestibility, pH and VFA's, it seems that bacterial inoculation of common reed silage with 75 percent above of standard level had the best results and this addition level is recommended.
