Data sheet: Phytases

Phosphorus is an essential mineral for bone mineralization, energy metabolism, and nucleic acid synthesis. Therefore, strategies to maximize the utilization of phosphorus present in cereals and legumes used in swine nutrition are important, such as the use of phytases. This data sheet describes the structure, types, mechanism of action, and application of phytases.

Summary of the 27th IPVS and 15th ESPHM-ECPHM: Reproduction, welfare, and nutrition

In this third installment, Antonio Palomo summarizes the papers presented on reproduction, nutrition, precision livestock farming, and other aspects of swine production.

NutritionAbstract

Evaluation of multi-carbohydrase and phytase complex dietary addition on nutrient digestibility, growth performance, and bone mineralization in growing-finishing pigs

Multi-enzymes supplementation may improve nutrient digestibility, bone mineralization, and growth performance in fattening pigs.

NutritionAbstract

Effect of increasing doses of bacterial phytase (Citrobacter braakii) on performance and carcass characteristics in growing-finishing pigs

Bacterial phytase supplementation may improve performance and environmental impact of swine production while reducing dietary inorganic phosphorus in growing-finishing diets.

NutritionAbstract

Adding high‐dosing Aspergillus oryzae phytase to growing-finishing pig diets

High-dosing A. oryzae phytase supplementation may have a beneficial impact on digestibility, performance and carcass traits in growing-finishing pigs.

NutritionAbstract

Beneficial effects of adding a multi carbohydrase and phytase complex on growing-finishing pig performance

Multienzyme complex may be taken into account as a successful strategy to compensate nutrient variability in swine diets.

NutritionAbstract

Effect of novel phytases on weaned piglet performance, digestibility and bone mineralization

The addition of phytases derived from E. coli, appAT1 and appAT2, significantly improved the final BW and FCR of pigs.

NutritionAbstract

Effect of increasing dietary levels of a novel 6-phytase on piglet performance and bone mineralization

The addition of phytase in piglet diets improves their performance due to a better utilization of phytate-P.

NutritionAbstract

Microbial phytase supplementation of low-P sorghum-canola meal diets with no added inorganic phosphorus in swine

Aspergillus niger phytase supplementation may contribute to inorganic P reduction in grain-oilseed meal diets.

NutritionAbstract

Replacing inorganic phosphate with a Buttiauxella phytase on growing-finishing pigs

Buttiauxella phytase supplementation may be a suitable strategy to completely replace inorganic phosphate in swine diets.

NutritionAbstract

Effects of low iron diet and phytase super-dosing on weaner pig performance

Dietary phytase superdosing may be a useful strategy in iron deficit status like after weaning occurs.

DuPont extends fastest-acting phytase product line in Europe

Fastest-acting phytase activates earlier in the animal’s digestive tract, improving profitability and performance while reducing waste and improving environmental footprint.

AB Vista reveals phytase superdosing strategies to help European producers maximise mineral release

Phytate is present in all plant-derived feedstuffs and binds with minerals such as zinc and copper, leaving them undigested by the animal and excreted into the environment.

NutritionArticle

Update on the use of phytase in swine

The use of proven phytases in swine, is recognized to be an extremely useful tool for nutritionists not only in formulating more affordable feed without altering animal performance, but even improving it.

NutritionAbstract

The P digestibility is higher in the low than normal phytate pea-based diet

Phytase supplementation increased P and amino acid digestibility in low and normal phytic P pea cultivars.

NutritionAbstract
