“…However, during the starter/grower phase, the FI of birds offered the in the NC diet was reduced compared to NC+ birds, despite a slight increase in nPP (2.8 g/kg vs. 2.6 g/kg). The increased FI of NC+ birds (starter/grower, 7.6%; finisher, 4.0%; and overall, 5.8%) may be as a result of high levels of phytase [23,24,46]. The benefits of phytase addition to the growth performance of broilers have been widely documented with further benefits via the inclusion in superdose levels; for example, Pieniazek et al [47] reported that higher levels of phytase (2000 FTU/kg) resulted in a 9.1% increase in feed intake and 142 g increase in bird weight compared to birds offered conventional levels of phytase (500 FTU/kg) in corn/soya-based diets.…”

“…Phytate, an anti-nutritional present in plant feedstuffs such as soybean meal, cannot be digested by fish (Kumar et al, 2012;Oliva-Teles et al, 1998;Rodehutscord and Pfeffer, 1995). Besides, the deleterious effect of phytate on phosphorous availability also inhibits proteases, such as trypsin and pepsin (Liu et al, 2009), decreasing protein and AA digestibility (Lima et al, 2021;Spinelli et al, 1983). The presence of phytate in plant ingredients composing the P reference diet could explain the lower ADC of protein and AAs in the SMB-P diet compared to the SBPM-SP diet.…”
