The Effect of Wheat Bran Added to Canola Silage on Feed Value and in Vitro Organic Matter Digestibility

Abstract

This study was carried out to determine the effect of wheat bran as added to canola silage on the fermentation and in vitro organic matter digestibility. Canola was harvested and ensiled with 5% and 10% wheat bran in glass silos. With each treatment three parallel investigations were performed. Chemical, microbiological analyses and in vitro cellulase method were conducted on the silage which was opened on the 60th day of storage. According to the analysis of the control, 5% and 10% wheat bran treatments, crude protein reached 14.31%, 14.71% and 15.66%; ammonia-nitrogen reached 91.53, 85.43 and 85.34 g/kg TN; metabolisable energy reached 7.94, 8.27 and 8.51 MJ/kg KM; while organic matter digestibility was 61.45%, 63.93% and 62.92%, respectively. In conclusion, addition of wheat bran can increase dry matter content of canola silage.
