Abstract

Abstract

Application of additives in silage making is one of the management practices crucial at ensiling time, storage and feed-out phase to reduce nutrient loss and improve its nutritive value. The experiment was conducted to evaluate the effect of additives on physical properties and proximate composition of maize cob silage. The experiment was laid in a Completely Randomized Design (CRD) in three additives (urea, molasses, and yeast) and untreated maize cob using three replications. At the end of the experiment data generated were subjected to analysis of variance. The results revealed that physical properties (colour, aroma and pH) of maize cobs were improved in urea and yeast-based additives. The crude protein (CP) content increased significantly (P<0.05) with urea treatment (9.21%) while the fibre fractions (CF, ADF and NDF) decreased significantly (P<0.05) with urea treatment after 21 days ensiling period. Therefore, it can be concluded that addition of urea improved the physical, nutritional properties and preservation capacity of maize cob after 3 weeks ensiling period.
