were similar except that the GR treatment had more pro-portion of 0.45–0.9 mm particles (179 and 129 g/kg diet, respectively) and a less proportion of 0.2–0.45 mm particles (583and 623 g/kg diet, respectively) compared to the GM treatment (Table 2). However, the WR treatment had relatively moreproportion of particles of 1.25 mm and above compared to GM and GR diets (301, 38 and 30 g/kg diet, respectively).
