EFFICIENCIES OF USING THE DIGESTIVE ENZYME PRODUCT OF PHYTASE ON POULTRY

Abstract

The hydrolysis and absortion nutrients in feed has a key role for poultry productivety and breeding income. In the combined feed of poultry, phytate exist as a source of inorganic phosphor and also an anti-nutrient factor. Using phytase to hydrolyse this source of phosphor has a great significance for poultry, helping poultry absorb phosphor and minerals better, as well as the amount of inorganic phosphor in dung decrease significantly. The potential source of phytase could be received from many popular kinds of bacteria and fungi such as Bacillus sp., Pseudomonas sp., Escherichia coli, Citrobacter braakii, Enterobacter, Aspergillus terreus, A. ficuum, A. niger, A. fumigatus, and Thermoascus aurantiacus… Now, the market of phytase product in Vietnam is very abundant with most of products have imported materials. Moreover, the effect of experiments on some chicken genera is steady proof lead more and more large breeding farms add phytase into the ration of poultry, contributing to increase income and develop the raising toward a stably organic trend.
