Transgenic soybean expressing a thermostable phytase as substitution for feed additive phytase

Transgenic Plants Expressing Phytase Gene of Microbial Origin and Their Prospective Application as Feed

Phytate is the primary storage form of phosphate in plants. Phytases from microbial sources are supplemented to feedstuff of monogastric animals to increase the uptake of phytate phosphorus. The use of microbial phytase is associated with high production cost and also requires special care in feed processing. Expression of phytase in transgenic plants is an alternative approach to the productio...

IgE-mediated allergy to phytase -- a new animal feed additive.

BACKGROUND Although fungal phytase is frequently used as an additive to animal feed few investigations of its allergenic property have been conducted. METHODS Fifty-three subjects occupationally exposed to powdered phytase from Aspergillus niger were studied. Exposure data and symptoms were registered by the company physician. RESULTS Thirty-eight subjects complained of work-related respira...

Phytase: An Enzyme to Improve Soybean Nutrition

PSA-Nutrition: Feed Additives and Phytase

The developing immune system is particularly sensitive to environmental and hormonal influences. Genders can differ in this sensitivity as well. Because the heavy metal, lead, can suppress Th-1 associated function among perinatal thymocytes and cause a systemic loss of postnatal Th-1 function, we investigated the ability of in ovo administered lead and testosterone to alter thymocyte maturation...

Phytase and Other Phosphorus Reducing Feed Ingredients

This fact sheet has been developed to support the implementation of the Natural Resources Conservation Service Feed Management 592 Practice Standard. The Feed Management 592 Practice Standard was adopted by NRCS in 2003 as another tool to assist with addressing resource concerns on livestock and poultry operations. Feed management can assist with reducing the import of nutrients to the farm and...
