Abstract

The analysis of sugar beet vinasse, originating as the condensed molasses residue from yeast production, and the effect of vinasse on rumen fermentation, protozoa population and digestibility of nutrients was investigated in two experiments. In the first experiment, a ration containing vinasse and wheat straw was fed ad libitum and voluntary feed intake for each sheep was measured. In the second
experiment, four rumen fistulated Zandy sheep (40±0.5 kg BW) were assigned in a change over design in order to investigate the effects of vinasse on animal performance. At 2h post-feeding the ruminal pH value was decreased (p<0.005) in treatment groups. The ruminal NH3-N and protozoa population of rumen fluids were increased in all treatment groups. Compared to the control groups, voluntary feed intake and diet digestibility were higher in treatment groups. It can be concluded that the use of vinasse at the level of 100 g/kg DM of the TMR diet per sheep per day could improve the ruminal fermentation and voluntary feed intake and also diet digestibility, resulting in a relatively better performance.
