&NA; A total of 660 one‐day‐old Ross 308 broiler chicks were randomly distributed into eleven dietary treatments. Treatments included a maize‐soybean meal‐based diet with recommended calcium (Ca) and non‐phytate phosphorus (nPP) (positive control; PC), an nPP‐deficient diet (negative control; NC), NC diets supplemented with different levels of phytase (0, 500, 1,000, 2,000, 3,000, 4,000, 5,000, and 6,000 FTU/kg), a NC diet plus 0.15% myo‐inositol, and a NC diet with reduced Ca level (Ca to nPP… Expand
Effect of a high dose of exogenous phytase and supplementary myo-inositol on mineral solubility of broiler digesta and diets subjected to in vitro digestion assay.
TLDR
Correlations were noted between the solubility of P in the in vitro assay and that in the gizzard and jejunal digesta, and also with bird performance, confirms the usefulness of in vitro test. Expand
Evaluation of interactive effects of phytase and benzoic acid supplementation on performance, nutrients digestibility, tibia mineralisation, gut morphology and serum traits in male broiler chickens
Abstract A total of 720 one-day-old male broiler chickens were randomly allotted into nine treatments to evaluate the effects of different levels of phytase (Phy, 0.0, 500, and 1000 FTU/kg) andExpand
Effects of phytase and benzoic acid supplementation on growth performance, nutrient digestibility, tibia mineralization and serum traits in male broiler chickens
ABSTRACT This study was conducted to investigate the effects of phytase (Phy), benzoic acid (BA) and their interactions on growth performance, nutrients digestibility and tibia mineralization inExpand
Evaluation of high dietary phytase supplementation on performance, bone mineralization, and apparent ileal digestible energy of growing broilers
TLDR
All phytase sources were able to compensate the phosphorus deficiency and promote performance and bone mineralization and high levels of phytases showed a higher response when compared to the lower levels of supplementation. Expand
High doses of phytase on growth performance, bone mineralization, diet utilization, and plasmatic myo-inositol of turkey poults
TLDR
The supplementation of turkey poult's diets with high levels of phytase up to 4,000 FYT/kg improves diet utilization by increasing P digestibility and dietary metabolizability, leading to higher P content in the bone and enhancing MYO provision and absorption. Expand
Manipulation of plasma myo‐inositol in broiler chickens: effect on growth performance, dietary energy, nutrient availability, and hepatic function
TLDR
High‐level dietary INS supplementation did not affect bird growth performance, mineral availability, and endogenous losses, and there were no interactions between INS and P. Expand
Effects of phytase and multicarbohydrase on growth performance, bone mineralization, and nutrient digestibility in broilers fed a nutritionally reduced diet
Summary An experiment was conducted to evaluate the effects of phytase and multicarbohydrase (MC) on growth performance, bone ash, and nutrient digestibility in broilers fed a nutritionally reducedExpand
Effects of residual superdoses of phytase on growth performance, tibia mineralization, and relative organ weight in ducks fed phosphorus-deficient diets.
TLDR
Feeding increasing residual superdoses of phytase could counteract or exceed the negative effects of NC diet on growth performance, tibia mineralization, and relative organ weight in ducks. Expand
Effect of sequential feeding of phosphorus-deficient diets and high-dose phytase on efficient phosphorus utilization in broiler chickens
ABSTRACT An experiment was conducted to investigate the effectiveness of sequential feeding of a very low non-phytate P (NPP) diet supplemented with varying doses of phytase to broiler chickens. AExpand

Effect of High Phytase Inclusion Rates on Performance of Broilers Fed Diets Not Severely Limited in Available Phosphorus
TLDR
The concept that hydrolysing phytate and reducing the anti-nutritional effects ofphytate improves bird performance on marginally deficient diets that were not covering the P requirement of birds is supported. Expand
The effect of supplementary bacterial phytase on dietary metabolisable energy, nutrient retention and endogenous losses in precision fed broiler chickens.
TLDR
It can be concluded that supplementary phytase increases the retention (reduces the excretion) of dietary Zn and Na in broiler chickens, and the beneficial effects of the addition of exogenous phytases to poultry diets seems to be mediated through improved dietary nutrients absorption and reduced endogenous losses. Expand
Effect of super dosing of phytase on growth performance, ileal digestibility and bone characteristics in broilers fed corn-soya-based diets.
TLDR
It could be concluded that super doses of phytase in low-phosphorus diet were beneficial than the normal standard dose (at 500 FTU/kg) of phydase in diet of broiler chicken. Expand
Effects of microbial phytase supplementation on mineral utilization and serum enzyme activities in broiler chicks fed different levels of phosphorus.
TLDR
It is demonstrated that microbial phytase supplementation to low-P diets improved performance; P, Ca, Mg, and Zn use; and tibia weight and relative liver weight in broiler chickens. Expand
Supplementation of corn-soy-based diets with an Eschericia coli-derived phytase: effects on broiler chick performance and the digestibility of amino acids and metabolizability of minerals and energy.
TLDR
It can be concluded that the supplementation of diets containing 3 g/kg of available P with exogenous phytase can improve the performance of chicks to that of birds fed a diet containing 5 g/ kg of available K and the use of high doses of phyt enzyme can improve nutrient availability in poultry diets beyond that of dietscontaining lower (< 1,000 U/kg) phytases.

Impacts of calcium and phosphorus concentration, their ratio, and phytase supplementation level on growth performance, foot pad lesions, and hock burn of broiler chickens
Abstract Concerns about the environment, nutrition, and farm profits all point to the increasing importance of the phosphorus (P) content of a diet. Animals must now be fed near their P requirements.Expand
Response of broilers to feeding low-calcium and phosphorus diets plus phytase under different environmental conditions: body weight and tibiotarsus mineralization.
TLDR
The very low-TP wheat-soybean based diet supplemented with 600 U/kg of phytase was sufficient to optimize all the parameters measured in Experiment 1 but not in Experiments 2 and 3. Expand
The effect of microbial phytase and myo-inositol on performance and blood biochemistry of broiler chickens fed wheat/corn-based diets.
TLDR
It can be concluded that dietary supplementation with MYO or phytase was effective in improving performance of commercial broiler chickens, however, further work is required to explore complex ontogenetic effects of MYO and possible involvement of both myo-inositol and phytases in Na-dependent transport mechanisms.

Effect of dietary phytase and high available phosphorus corn on broiler chicken performance.
TLDR
Data indicate that total phosphorus can be reduced by at least 11% in diets prepared with HAP corn, or in diets supplemented with phytase, without affecting the performance or health of broiler chickens. Expand
Influence of superdoses of a novel microbial phytase on growth performance, tibia ash, and gizzard phytate and inositol in young broilers.
TLDR
Improvements in feed conversion ratio associated with superdoses of phytase may be attributed to phytate destruction and the provision of inositol. Expand
