چکیده
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 reduce the excretion of nutrients in manure.

P122 Effects of phytase supplementation on ileal digestibility of phytate phosphorus and total phosphorus of feed ingredients for broiler chickens
This study aimed to evaluate the effect of a heat stable phytase derived from Citrobacter braakii on true digestibility of P and on phytate dephosphorylation at the terminal ileum segment in broiler chickens. Four semi-synthetic diets, each containing either wheat, maize, soybean meal or rapeseed meal as the only source of phosphorus and calcium were supplemented with microbial phytase at 1000 ...
متن کاملPhytate and Phytase in Broilers --a Review
The vegetable feed ingredients used in the preparation of poultry feed contains nearly two thirds of the phosphorus as phytates. The phytates are not only indigestible /unavailable but also are known to interfere with the utilization of other nutrients. Apart from the anti-nutritional effects the phytates bind with other minerals and make them unavialble to the birds. One of the best ways to ov...
متن کاملPractical Application of Enzyme Supplementation in Swine
Introduction Application of enzymes to improve nutrients digestibility of plant-based feed ingredients for swine and poultry has now been studies for decades. Initially, the main focus was phytase to break down the phytate molecule and release the attached phosphorus molecules. In the last two decades, enzymes to assist digesting NSP were developed, tested, and commercialized. In the meantime, ...
متن کاملEffect of Microbial Phytase in Soybean Meal Based Broiler Diets Containing Low Phosphorous
A six wk feeding experiment was conducted with d-old four hundred broiler chicks (Ven Cobb) to determine the effects of microbial phytase (Allzyme) supplementation in soybean meal based broiler diet containing low phosphorous. These birds were randomly divided into four dietary treatment groups of 100 broilers each. Each treatment group was further sub-divided into five replicates of 25 broiler...
متن کاملMetabolism and Nutrition: Phytase and Minerals
An experiment was carried out to evaluate effects of temperature, pH, and incubation time on the stability of intrinsic phytases. The experiment was conducted as a 3*4*3*3 factorial arrangement with 3 feed ingredients (rye, wheat, and barley), 4 temperatures (T) (20, 38, 55, and 80°C), 3 pH levels (3, 5.5, and 8), and 3 incubation times (30, 60, and 120 min), with 2 replicates per treatment.
