However, higher relative weights of the gizzard at 28, 49, and 70 d, proventriculus at 49 d, and duodenum at 28 and 70 d of age were observed in geese fed the whole maize diet compared with those fed the ground diet (Lu et al., 2011a). Higher relative weights of theproventriculus and gizzard were found in geese fed on a 600 g/kg rice husk diet, and higher relative weights of the gizzard
