background: exogenous phytase enhances the utilization of plant phytate phosphorus in poultry. objectives: in the present study the effects of exogenous phytase was investigated on tibia bone characteristics of white quail. methods: in a 2x2 factorial arrangement, eighty, 11-day old unsexed chicks were randomly divided into 4 treatments of 20 replicates. all birds received one of four experimen...

The objective of the present study was to investigate the effect of dietary phytate and microbial phytase on the lipase activity, lipid metabolism and mRNA expressions of fatty acid synthase (FASN) and leptin in broiler chickens. The study was conducted as a 2 x 3 factorial arrangement of treatments with phytate phosphorus at 0.20 and 0.40 % (added as the sodium phytate) and supplemental microb...

Phosphorus absorption in ruminants was analysed from a database described in a previous article. For common values of ingested phosphorus (2.5-5.0 g x kg(-1) of DM), 0.73 of dietary phosphorus is absorbed. The remaining variability is probably due to phosphorus quality. Phosphorus absorbed from silage, cereal, cereal by-products and hay differs greatly. The current true absorption coefficient u...

Since the mono gastric animals are not capable of metabolizing phytate, a rich source of Phosphorus, undigested phytate is excreted in manure without absorbed for metabolism and poses serious phosphorus pollution in the environment. Therefore, supplementation of phytases into animal feed is expected to solve the above problems. The present investigation deals with cloning and expression of a ph...

Fertilizer phosphorus (P) is a finite resource, necessitating the development of innovative solutions for P fertilizer efficiency in agricultural systems. Myo-inositol hexakisphosphate (phytate) constitutes majority identified organic many soil types and poorly available to plants. Incorporating phytase-producing biofertilizers into presents viable environmentally acceptable way utilizing from ...

This experiment was conducted to investigate the effects of supplemental phytase in a corn-wheatsoybean meal basal diet on phosphorus (P) digestibility and performance of broiler chicks. 378 one-day old broiler chicks (Ross 308) were allocated to 3×3 factorial arrangements with three levels of phytase enzyme (0, 500 and 1000 FTU/kg) and three levels of non-phytate P (100, 80 and 60% of NRC requ...

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...

The concentration of phytate is an important consideration when analyzing feed grain for livestock. Simple sequence repeat markers Satt237 and Satt561 were found to be linked to quantitative trait loci (QTLs) for phytate concentration in soybean [Glycine max (L.) Merr.] seed. Previous research also established a signifi cant correlation between seed inorganic phosphorus (Pi) and seed phytate. T...

Phytase is traditionally supplemented into broiler diets between 300 and 600 phytase units (FTU)/kg. This supplementation releases phosphorus (P) from phytate in feed ingredients. The obvious benefit is the increase in available nutrients. Another benefit, when phytase is added to corn-soybean meal based diets, the production costs are reduced, leg abnormalities are minimized and bird growth ma...

Phosphorus is an important macronutrient, but its availability in soil is limited. Many soil microorganisms improve the bioavailability of phosphate by releasing it from various organic compounds, including phytate. To investigate the diversity of phytate-hydrolyzing bacteria in soil, we sampled soils of various ecological habitats, including forest, private homesteads, large agricultural compl...
