Effects of Phytobiotic of Curcuma aeruginosa, Curcuma longa and Zingiber officinale on the Performance and Carsass Quality in Broiler

Abstract

The purpose of this study was to investigate the effects of the use natural antibiotics (phytobiotic) Curcuma aeruginosa, Curcuma longa and Zingiber officinale as an alternative antibiotic on the performance of broiler. Experimental design was a Completely Randomized Design using 440 broiler of one day-old chicks and randomly divided into 11 treatments with 4 chickens for each treatmen. The dietry treatments were negative control (T01), a basal diet without any feed additives and positive control (T02), a basal diet with bacitracin, and basal diets with additional different levels (0.75, 1.0, and 1,5%) of Curcuma aeruginosa (TI1, TI2, and TI3), Curcuma longa (KU1, KU2, and KU3) and red ginger (JM1, JM2, and JM3), respectivelly. The results showed that the addition of low-dose phytobiotic (0.75%) in broiler have produced a different effect (P .05) with positive control treatment of bacitracin. In conclusion, the use of phyitobiotics Curcuma aeruginosa, Curcuma longa and red ginger has showed their function as growth promoters in low dose.
