Abstract
Wheat and corn silages are widely used as ruminant feed in Israel due to their availability and cost-effectiveness. To ensure long-term preservation without compromising nutritional quality, effective methods must be employed. Inclusion of additives during harvest and ensiling can enhance efficiency and address preservation challenges. In the current study, the effects of microbial inoculum (MI) and urea on the chemical composition, amino acid profiles, aerobic stability, and in vitro digestibility of wheat and corn silages were investigated. Samples of wheat and corn were subjected to four treatments: control, MI, Urea, and a combination of MI+Urea. The treatments were ensiled in anaerobic conditions and opened after 1, 7, 14, or 28 days. Results showed that additives improved the quality parameters of wheat and corn silages. The inclusion of MI produced the most aerobically stable silages. The inclusion of urea in silages deteriorated aerobic stability. Additives improved in vitro cell wall carbohydrates digestibility in both silages and was the best when MI was combined with urea. These results imply additives could be incorporated in silages to enhance their nutritional value, aerobic stability and digestibility. Nonetheless, increased CP content with additives was not accompanied with parallel increase in amino acids content in corn silage.
