Supplementing microbial phytase to diets for swine and poultry
… conducted to determine the efficacy of Natuphos® phytase for improving the bioavailabilities of phytate P and other nutrients (CP, AA, Ca, and Zn) bound to phytate in the diets for pigs, broilers, and turkey poults, and to evaluate P and Zn equivalency values of phytase. In a 5-wk study with young …

Phytate Extraction and Stimulation of Phytase by Zn & Mg in Seeds
… effects of zinc and magnesium on stimulation of phytase in seeds were determined by comparing the quantity of substrate (phytate) with that of the control group.</p> <p>The method for analyzing the phytate content was based on dry weight. After phytic acid was extracted by hot HCl, ferric phytate …

Measurement of Phytase Activity in a Clymer Forest Soil Using the TInsP5 Probe
Measurement of soil phytase activity (PA) and delineation of the impact of this important phosphomonoesterase on the P-cycling process in soil and sediments suffer from the lack of a reliable assay. A method for measuring PA in soil that promises to be accurate and reliable has been recently …

Application of microbial phytase and its influencing factors in vivo and in vitro
… conducted in vivo to investigate the efficacy of phytase in improving the availability of phytate P as influenced by dietary Ca:total P (tP) ratios for pigs, broilers, and turkey poults. In pigs and poultry, microbial phytase was effective in improving performance, P and Ca digestibility, bone …

Phytase Impacts Various Non-Starch Polysaccharidase Activities on Distillers Dried Grains with Solubles
… (NSPase) inclusion rates and combinations with phytase on the ability to release reducing sugars were investigated. Distillers dried grains with solubles was tested in vitro in combination with hemicellulase (0, 0.1, 1, and 10 U/g of DDGS), cellulase (0, 1.5, 15, and 150 U/g of DDGS), xylanase …

Efficacy of an Escherichia Coli Phytase for Improving Mineral Utilization in Pigs and Chickens
… values of approximately 0.04% for the other two phytases, relative to monobasic potassium phosphate. In young pigs, 400 FTU/kg of EcoPhos(TM) released 0.11% P, compared to P-release values of 0.08 and 0.04% for NatuphosRTM and Ronozyme RTM, respectively. EcoPhos(TM) (500 FTU/kg) also released …

Efficacy of exogenous phytase and protease enzymes on performance and gastrointestinal health in broiler chickens
The efficacy of exogenous phytase and protease, alone and in combination, or in combination with AGP, zinc bacitracin on performance and intestinal morphology in broilers was tested. Broilers were fed a diet containing nutrients at recommended levels (positive control, PC) with no enzyme …

The interaction of dietary phosphorus and exogenous phytase concentrations on nutrient metabolism of beef cattle
… for nonruminants is the dietary addition of phytase, an enzyme that releases P bound to phytate, making it more available for absorption (Lei et al., 1993; Ravindran et al., 2000; Jongbloed et al., 2004). The microbial population in the rumen produces phytases; however, passage rate, …

Effect of Form and Amount of Phosphorus and Phytase Supplementation on Phosphorus Utilization by Ruminants
… of levels of dietary P, chemical form of P, and phytase supplementation in ruminants. For Exp. 1, 24 steers (average BW = 229 kg) were allotted to two diets containing 0.12 and 0.19% dietary P for a 112-d growth trial. The steers were individually full-fed, weighed every 14 d, and blood samples …

An in vitro assessment of the effects of feed-grade trace minerals on commercial phytase activity
Exogenous phytases have the capacity to increase the nutritional value of animal feeds through the hydrolysis of phytate-bound phosphorus. Inorganic trace minerals (ITM) routinely added to feed can negatively impact phytase activity. Recent research has shown that replacement of ITMs with organic …
