Evaluation of the responses of broiler chickens to varying concentrations of phytate phosphorus and phytase. II. Grower phase (day 12-23 post hatching)

O. O. Babatunde et al.

Summary: This study investigated the effects of phytate and phytase concentration on the growth performance and nutrient utilization of broiler chickens. The results showed that phytate reduced the growth performance and nutrient utilization, while phytase ameliorated these negative effects.

Influence of exogenous phytase supplementation on phytate degradation, plasma inositol, alkaline phosphatase, and glucose concentrations of broilers at 28 days of age

R. Kriseldi et al.

Summary: Adding 1,200 FTU/kg phytase reduced IP6 concentration in gizzard contents and ileal digesta while increasing inositol concentrations. However, this did not result in increased plasma inositol concentration, warranting further investigation.

Effect of different doses of phytase and protein content of soybean meal on growth performance, nutrient digestibility, and bone characteristics of broilers

Rafael F. Sens et al.

Summary: This study found that higher phytase doses for broilers can improve weight gain, myo-inositol provision, and bone mineral composition. When combined with soybean meal of greater nutritional quality, higher phytase doses can enhance nutrient ileal digestibility.

Inositol and gradient phytase supplementation in broiler diets during a 6-week production period: 2. Effects on phytate degra-contents 1

R. Kriseldi et al.

Summary: The experiment demonstrated that supplementing phytase up to 40,500 FTU/kg can significantly reduce phytate concentrations in the gizzard and ileal digesta contents of broilers, leading to increased plasma inositol concentration.

Inositol and gradient phytase supplementation in broiler diets during a 6-week production period: 1. effects on growth performance and meat yield

R. Kriseldi et al.

Summary: The experiment showed that the addition of 40,500 FTU/kg of phytase significantly improved the broiler's BW gain, reduced feed conversion, and affected carcass and breast meat weights. In contrast, inositol supplementation did not offer additional benefits compared to phytase supplementation.

Effect of two phytases at two doses on performance and phytate degradation in broilers during 1-21 days of age

Yueming Dersjant-Li et al.

Summary: At equivalent dose-level, Phy B showed a higher phytate degradation rate compared to Phy C, and this is correlated to the performance of the broilers.

Multiexperiment evaluation of increasing phytase activity from Optiphos® and Optiphos Plus® on 21-day broiler performance and tibia mineralization

V. E. Ayres et al.

Summary: The study found that phytase has positive effects on broiler performance and bone mineralization. As phytase activity increases, performance and bone mineral metrics improve in a curvilinear fashion, with the value of super-dosing depending on the product used and the cost-benefit economics. When comparing nonlinear response slopes, Optiphos Plus showed approximately 20% higher efficacy than Optiphos at similar levels.

Safety assessment of a novel thermostable phytase

Jana Novakova et al.

Summary: A novel 6-phytase with improved thermostability, named Phytase TSP, was developed for animal feed. Safety evaluation included genotoxicity and subchronic toxicity testing, with results showing no adverse effects and no genotoxicity at doses of up to 1000 mg/kg body weight/day in rats. The new phytase was considered safe for use as a feed additive.
