A, 5 mm, 0.1%; B, 1 mm, 0.1%; C, 5 mm, 1%; D, 1 mm, 1%; Barley grinding size: 5 mm, coarsely milled; 1 mm, finely milled. Inoculation rates: 0.1%, 0.1% by volume of raw materials; 1%, 1% by volume of raw materials.
All values are mean±SD (n=3) and different superscript letters in the same column indicate significant differences by Duncan’s multiple range test (p<0.05).
