Safety and efficacy of Nutrase P (6-phytase) for chickens for fattening, other poultry for fattening, reared for laying and ornamental birds. [PDF]

EFSA J, 2020
Nutrase P is available in powder, granulated, thermostable granulate and liquid forms. It is based on a 6-phytase produced by a genetically modified strain of K. phaffii. The production strain contains four copies of the ampicillin resistance gene and one copy of a bleomycin resistance gene.

Influence of different levels of calcium, non-phytate phosphorus and phytase on apparent metabolizable energy, nutrient utilization, plasma mineral concentration and digestive enzyme activities of broiler chickens

Journal of Applied Animal Research, 2018
The study investigated the effect of different levels of dietary Ca, non-phytate phosphorus (NPP) and phytase on the nutrient utilization of broiler chickens. A total of 576 day-old broiler chicks (Ross 308) were offered diets containing 3 concentrations

Stimulatory effect of medium components on phytase production by Aspergillus niger and biotechnological application as a poultry feed additive

Kuwait Journal of Science, 2022
The present study deals with the production of phytase from Aspergillus niger using solid-state fermentation (SSF). Appropriate concentration of different components of the growth medium played an important role for the higher production of phytase ...

Phytase activity in lichens [PDF]

, 2015
Phytase activity was investigated in 13 lichen species using a novel assay method. The work tested the hypothesis that phytase is a component of the suite of surface-bound lichen enzymes that hydrolyse simple organic forms of phosphorus (P) and nitrogen (

The effects of feed budgeting, complete diet blending, and corn supplement blending on finishing pig growth performance in a commercial environment [PDF]

, 2010
A total of 808 pigs (PIC 337 x 1050, initially 78.4 ± 1.4 lb BW) were used to compare different feed-blending strategies for finishing pigs using the FeedPro system (Feedlogic Corp., Willmar, MN).

A Feed Additive Containing Encapsulated 6-Phytase within Recombinant Yarrowia lipolytica Cells Produced by Cultivation on Fat-Containing Waste

Applied Sciences, 2022
Feed phytases are purchased as a dry culture medium of secreting producers, mostly micellar fungi. These preparations are required to withstand heating up to 75–80 °C because they are intended for mixing with feed components with subsequent granulation by spray drying.

Efficacy of New 6-Phytase from spp. on Growth Performance and Nutrient Retention in Broiler Chickens Fed Corn Soybean Meal-based Diets [PDF]

Asian-Australasian Journal of Animal Sciences, 2015
A total of 420 day-old male Ross chicks were weighed at d 1 of life and assigned to test diets to assess the efficacy of a new Buttiauxella spp. phytase expressed in Trichoderma reesei. Diets were: positive control (PC) adequate in nutrients and negative

In vitro versus in situ evaluation of the effect of phytase supplementation on calcium and phosphorus solubility in soya bean and rapeseed meal broiler diets [PDF]

, 2014
1. In vitro assays provide a sensitive and economic tool to evaluate dietary effects, but have limitations. In this study, the effect of phytase supplementation on solubility, and presumed availability, of calcium (Ca) and phosphorus (P) in soybean meal (
