Abstract

The object of this study were determined the effect of adding urea (0,2%) and molasses (4%) to barley and straw on in vitro gas and methane production, in vitro fermentation characteristic (pH and ammonia nitrogen concentration) and in vitro digestibility, dry matter, organic matter and metabolizable energy, the samples incubated in 39oc water path for 24,48,72 and 96 h., the results indicated that there were significant decrease (p
