diets, the multi enzyme supplementation containing phytase
enzyme was used that may be decrease the detrimental effect
of phytate or fiber content of SM. Our results shows that
ADG, FE and DFI of quails were not affected by the increasing level of SM are in agreement with earlier studies
in broiler and layers chicks (Bell et al.1990; Ravindran and
Blair, 1992; Mamputu and Buhr, 1995; Yamauchi et al.
2006) that SM could safely be used up to 150 g/kg in the
broiler diets without negative effect on performance. In
contrast, Farran et al.(2000)reported that weight gain of
broiler chick in diet containing 120 g/kg SM was reduced
than that control diet. These researchers concluded that an
increase in oxalate and phytate of the diet containing SM
could decrease the weight gain. It seems that, this inconsistency in weight gain between last study, with a diet with
120 g SM/kg, and our study, with a diet with 150 g SM/kg,
may be due to the addition of phytase enzyme to diets in
our study.
