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

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

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 ...

Evaluation of High Doses of Phytase in a Low-Phosphorus Diet in Comparison to a Phytate-Free Diet on Performance, Apparent Ileal Digestibility of Nutrients, Bone Mineralization, Intestinal Morphology, and Immune Traits in 21-Day-Old Broiler Chickens

Animals, 2022
The supplementation of feed with phytases enables broilers to utilize more efficiently phosphorus (P) from phytic acid (IP6), the main storage form of P in plants. The current study evaluated the addition of 500, 1000, and 3000 FTU of phytase per kg to a

Effects of a novel bacterial 6-phytase on nutrient digestibility in lactating dairy cows

Journal of Dairy Science
Undigested P and N are excreted and contribute to the environmental effects of dairy farming. Degradation of phytate in the rumen has been shown to be high but variable, leading to incomplete phytate-P (PP) utilization and resultant antinutritional effects of phytate along the gastrointestinal tract.

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.

Effect of Bacterial Phytase on Growth Performance, Nutrient Utilization, and Bone Mineralization in Broilers Fed Pelleted Diets

Animals, 2023
The influence of a bacterial 6-phytase on growth performance, coefficient of apparent ileal digestibility (CAID) of nutrients, blood parameters, and bone mineralization in broilers was evaluated. A total of 630 one-day-old male broilers were allocated to

Heat Stress in Quail: Impacts on Health and Productivity, and Mitigation Strategies

Animal Research and One Health, EarlyView.
Heat stress disrupts physiological homeostasis in quail, inducing oxidative stress, immune dysregulation, and metabolic imbalance, which impair growth, reproduction, product quality, and welfare. Integrating nutritional, environmental, and genetic–epigenetic strategies enhances thermotolerance, sustains productivity, and supports climate‐smart quail ...

Microbial Phytase and Phosphorus Utilization by Broiler Chickens

Scientific Papers Animal Science and Biotechnologies, 2023
The aim of study was to investigate the mathematical and statistical assesment of the micorbial 6-phytase efficacy on phosphorus utilization at broiler chickens Cobb 500. Broiler chickens fed commercial feed mixtures based on soyabean-maize meal.
