Effect of addition level of Pandanus amaryllifolius Roxb. on Broiler performances at starter period

Abstract

Pandanus amaryllifolius Roxb. leaves are commonly used as food additives in many countries. Beside to improve taste, it is recognized to contain various compound groups namely alkaloid, saponins, flavonoids and tannins that have a role in antibacterial activity. However, the current research aim was to examine effect of using Pandanus amaryllifolius Roxb. leaves as feed additive in broilers. The method used was experiment, employing 6 treatments included P0: control feed; P0: control feed added with 0.1% zinc bacitracin; P1: control feed added with 0.5% Pandanus amaryllifolius Roxb. leaves powder; P2: control feed added with 1.0% Pandanus amaryllifolius Roxb. leaves powder; P3: control feed added with 1.5% Pandanus amaryllifolius Roxb. leaves powder; P4: control feed added with 2.0% Pandanus amaryllifolius Roxb. leaves powder. The variables measured were feed consumption, body weight gain and feed conversion ratio. The results indicated that in all variables no significant results were reported. Those indicated that addition of Pandanus amaryllifolius Roxb. leaves powder in broiler feed did not affect growth performances of broiler. It is concluded that the use of Pandanus amaryllifolius Roxb. leaves powder as feed additive did not change growth of broiler, probably due partly to its antibacterial effect.
