The Effects of Adding Urea and Molasses to Corn Harvested at Dough Stage on Silage Fermentation Quality, in vitro Organic Matter Digestibility and Metabolic Energy Contents

摘要

The aim of this study was to evaluate the effects of ensiling corn harvested at the milk stage by addition of various amount of Molasses (M), Urea (U) and Urea + Molasses (UxM) on quality, in vitro Organic Matter Digestibility (IVOMD) and Metabolic Energy (ME) contents. Five silage samples from 16 treatment groups were prepared in 1 l jars and incubated for 70 days. The ME values and IVOMD with lactic acid levels of 1% U added silages were higher compared to other silages. It has been concluded that either unsupplemented or 1% U added ensiling will be a suitable ensiling technique to corn.
