Cisgenic barley with improved phytase activity

Plant Biotechnology Journal, 2011
SummaryThe cisgenesis concept implies that plants are transformed only with their own genetic materials or genetic materials from closely related species capable of sexual hybridization. Furthermore, foreign sequences such as selection genes and vector‐backbone sequences should be absent. We used a barley phytase gene (HvPAPhy_a) expressed during grain

Isolation and identification of phytase-producing strains from soil samples and optimization of production parameters [PDF]

Biological Journal of Microorganism, 2017
Introduction:Phytase can be used as a feed additive to catalyze the hydrolytic degradation of phytate as the major storage form of natural phosphorus. Phytase is produced by a wide range of bacteria, fungi and yeasts.

Supplementation of fungal and/or bacterial phytase in broiler diets formulated with reduced phosphorus level and different calcium contents

Revista Brasileira de Zootecnia, 2018
The objective of the current study was to evaluate the effects of three calcium:available phosphorus (Ca:aP) ratios and different supplementation with phytases from different origins on performance and ash, Ca, and P contents in the tibia of broilers.

Limestone particle size, calcium and phosphorus levels, and phytase effects on live performance and nutrients digestibility of broilers

Poultry Science, 2020
Limestone particle size (PS) affects its solubility and thus can influence broiler performance by altering the rate of calcium (Ca) release into the gastrointestinal tract.

Influence of supplemental phytase on growth performance, digestion and phosphorus balance of lambs fed sorghum-based diets

Italian Journal of Animal Science, 2010
Phosphorus excretion in lambs from urine and faeces is considerably high due to elevated concentration of grains in the diets. This study evaluated the effect of supplemental phytase on in vitro dry matter degradation (IVDMD), feed intake, growth ...

Research Note: Evaluation of phytic acid disappearance, ileal P digestibility, and total tract P retention in canola meal supplemented with increasing levels of exogenous phytase using conventional and cecectomized precision-fed roosters and growing chicks

Poultry Science
: Apparent ileal digestibility (AID) of P, apparent total tract retention (ATTR) of P, and phytic acid disappearance in canola meal were evaluated in the presence of increasing levels of exogenous phytase.
