Type: article
Abstract: The current study aimed to compare the nutritional, chemical, and fermentative changes of maize silages with some additives prepared in standard glass jars (SGJ) and vacuum-packed model polyethylene bags (VP, Rostock). The treatment groups were control group (no addition), barley group (grinded barley addition 20 and 40 g kg-1), lactic acid bacteria (LAB) group, and LAB+enzyme mixture group. The ensiling method had no effect on the pH of the silage. (P=0.974) but the pH was increased with LAB addition (P=0.030). The dry matter (DM) contents of silages were increased by barley addition (P=0.030). Silages hemicellulose (HEM) content was decreased by ENZ inoculation (P=0.017). Silages total carbohydrates (TC) and metabolizable energy (ME) concentrations were highest in 40 g kg-1 barley group (P<0.01). The silages fleig point (FP) was decreased by LAB inoculation (P=0.016). Silage ether extract (EE), ADF, NDF and crude cellulose (CC), total digestible nutrients (TDN), and fermentation parameters (acetic, butyric, lactic and propionic acids) were not impacted by the ensiling methods or silage additives (P>0.05). These results showed that vacuum-packed polythene bags do provide practical, flexible, and cost-efficient alternative to fixed-capacity glass containers for laboratory scale silage experiments.
