Nutrient Content and in sacco Digestibility of Barley Grain and Sprouted Barley

The studies reported in this research examined the nutrient profile of barley grain when it was sprouted hydroponically Following sprouting, the measurement of animal response at experimental level and also in a commercial setting was performed in order to test the hypothesis that sprouting gives rise to hydroponic sprouts that give higher animal responses In first part of the experiment, barley grain was sprouted hydroponically for a duration of 7 days Daily sampling of the sprouts was done to assess DM concentration and also to determine the nutrient concentration on day 7 in comparison to the unsprouted grain Results showed a 21 9% loss in DM from the original seed after sprouting for a period of 7 days A loss of 2% GE was recorded after comparing the sprouts with the original grain The CP, ash and all other minerals except potassium were lower in concentration on a DM basis in the barley grain than in the sprouts This was considered to be a reflection of a loss in DM after sprouting causing a shift in concentration of these nutrients The second phase of the experiment involved in sacco degradation of hydroponic barley sprouts and the unsprouted grain in the rumen of Merino sheep There was no significant difference (p>0 05) in in sacco degradation when unsprouted grain was compared with hydroponic barley sprouts It was concluded that the loss of 21% DM followed by a lack of difference in in sacco degradability disproved the presence of any advantage of sprouts over the original grain
