Use of fitasa in fowl feeding

Abstract

Most of the phosphor present in plant components exists as Fitic Acid, mixed with Potassium, Magnesium and Calcium salts. Primal components from plants provide 60-75% of P with Fitatoes, a component which endogenous enzymes of birds cannot degrade. Thus, diets are reinforced with mineral supplements (bicalcic phosphate), rich in absorbable calcium and phosphor. In order to improve the use of fitic phosphor in cereals, and to lower pollution by phosphor in water and soil, it was decided to add fitasas to reproductive birds diets. Low levels of absorbable phosphor increase dead animal percentage, reduce production, weight and eggshell quality, lowers incubability and increases broken egg percentage. Diet #1 had 0.5791% total P, 5.8717 Ca: P, 240g/TN (600 FTU) fitasas. Diet #2 had .7363% P, 4.6175 Ca: P, and no fitasas. Both had 3.4% Ca and 0.38% P. Tests included descriptive statistics and mean value matching with p<0.05.
