The Influence of Phytase Enzyme to Laying Performance and Quality of Egg Shell of Golden Arabian Chicken
Department of Animal Science, Faculty of Agriculture, Universitas Sriwijaya, South Sumatra, 30662, Indonesia
Poultry has low ability to digest dietary fibre and to process phytate. Rice bran is intensively used in poultry ration although it contains little bit higher in fibre and phytate. The purpose of this study was to find out the optimal level of phytase the enzyme that could break down phytate in the ration of Golden Arabian chicken to increase performance and physical quality of the eggs. This study used 90 golden arabian chickens (Golden Brakel Kriel), approximately five months of age. Individual cage with a wire floor was equipped with a feed and drinking troughs. Experimental ration was with a mixture of corn, rice bran, commercial concentrate, and mineral mixture. Phytase was added at the level of: zerro, without phytase = P1; 100 FTU/ kg of ration; 200 FTU/kgof ration = P2; 300 FTU/kg of ration =P3; 400 FTU/ kg of ration = P4; and 500 FTU/kg of ration = P5. Experimental design that used in this study was Complete Randomized Design (CRD) with six treatments and five replications and three golden arabian chickens per experimental unit. Results showed that the addition of phytase in golden arabian chickens ration improved the hen day production (P <0.05) up to 71.43% and increased the physical quality, especially weight of eggshell significantly (P <0.05) up to 4.516 gram (phytase enzyme 300 FTU/kg) . In conclusion, that the level of the phytase of 300 FTU/kg of ration was the most optimal dose to increase the daily egg production and improve the physical quality. However, the addition of phytase did not affect to feed consumption, feed efficiency, eggshell thickness and eggshell thickness index.
