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 (P0.05). 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.
