Safety assessment of a novel thermostable phytase

Toxicology Reports, 2021
A novel 6-phytase (Phytase TSP, trade name OptiPhos® PLUS) with improved thermostability has been developed for use in animal feed. The safety of the new phytase was evaluated by testing for genotoxicity and subchronic toxicity.

Purification and Characterization of Phytase from Fruit Bodies of Local mushroom Pleorotus ostreatus Grown by Solid State Fermentation

Tikrit Journal of Pure Science, 2023
Phytase produced from an edible local mushroom P.ostreatus11L was purified in three steps, in precipitation with ammonium Sulfate (saturation ratio70%), the specific activity of phytase increased from 0.38u/mg protein in crude extract to 0.77 u/mg ...

Enhanced Farrowing Efficiency and Sow Performance with <i>Escherichia coli</i>-Derived 6-Phytase Supplementation During Late Gestation and Lactation. [PDF]

Animals (Basel)
Phytase releases phosphorus from phytate and may confer extra-phosphoric benefits in sows. We tested whether Escherichia coli-derived 6-phytase during late gestation and lactation improves sow and litter outcomes. In a randomized complete block trial, 186 TN70 sows received a phytase-free positive control (adequate Ca and available P) or Ca- and P ...

Potential immune-modulatory effects of wheat phytase on the performance of a mouse macrophage cell line, Raw 264.7, exposed to long-chain inorganic polyphosphate [PDF]

Animal Bioscience, 2021
Objective This experiment was conducted to find out the immunological effects of wheat phytase when long-chain inorganic polyphosphate (polyP) treated with wheat phytase was added to a macrophage cell line, Raw 264.7, when compared to intact long-chain ...

Fate of thymol and its monoglucosides in the gastrointestinal tract of piglets [PDF]

, 2020
The monoterpene thymol has been proposed as a valuable alternative to in-feed antibiotics in animal production. However, the effectiveness of the antimicrobial is comprised by its fast absorption in the upper gastrointestinal tract.

Evaluation of Commercial 6-Phytases on Growth Performance, Bone Mineral Content, and Feed Digestibility of Broiler Chicks

The Journal of Poultry Science, 2022
We evaluated the effects of 6-phytases on the growth performance of broilers (UK Chunky) under the recommended supplier-application dosage of each phytase. A nutritionally sufficient standard diet was administered as the base diets in the positive control feed.

A novel consensus bacterial 6-phytase variant added to phytate-rich diets totally replaced inorganic phosphate in broilers [PDF]

Journal of Applied Animal Nutrition, 2022
The capacity of a novel bacterial 6-phytase variant (PhyG) to totally replace dietary supplemental inorganic phosphate (Pi) in broilers aged one day old was evaluated using a phased dosing strategy and reduction in dietary phytate. A total of 1,248 one-day-old Ross 308 broilers were assigned to 24 pens (52 birds/pen, 12 pens/diet, six each males and ...
