Material type: materialTypeLabelBookPublisher: 1998Subject(s): Department of Animal NutritionDDC classification: 0568,T Dissertation note: The phosphorus availability in broiler ration was improved by the supplementation of phytase enzyme. A unit of phytase is defined as the quantity of enzyme that liberates LU. mol of inorganic P/mm. from 5.1 mm sodium phytate at pH 5.5 and 37°C. Six weeks old forty (40) broiler birds were housed in individual cages in a room maintained with standard conditions. Birds were randomly divided into four groups having 10 birds each including control group. The following level of phytase were used 0, 300 U, 600 U, and 900 U. A preliminary period of 7 days was observed to remove the effect of previous diet and then feed intake and production of excreta was measured quantitatively per pen over three consecutive days. By the supplementation of the different levels of phytase enzyme the P availability was significantly (P<0.01) increased in different groups. Maximum phosphorus availability was achieved in D groups similarly minimum P availability was achieved in A group (control). rphe data was statistically analyzed by using the complete randomized block design highly significant (P<0.01) difference was observed in various rations. For the comparison of means DMR test was applied which showed significantly (P<O.O1) higher P availability in ration D as compared to the remaining rations (A, B and C). The control ration was economical ration in this experiment. By supplementing phytase the cost of the ration was increased. rrhe results of present study proved that use of phytase is uneconomical but maximum phosphorus availability could be achieved by using the phytase enzyme in poultry rations.
