Abstract

This experiment was designated to investigate the effects of dietary supplementation with various concentrations of oriental herbal natural extract, Galla Rhois (GR), on growth performance and meat quality on broiler chickens. A total of 80 two-day-old broiler chicks were randomly designated to four groups, GR 0% diet (control), GR 0.10%, 0.25%, and 0.50%-treated diet, composed 20 chicks and fed a standard diet supplemented with GR and monitored the growth performance every 5 days during 30 days. Body weight gain (BWG) in all treated groups was increased compared to control group during overall period, showing significant (P<0.05) increase in GR 0.25% and 0.50% independent on concentration, though all group represented a similar level of feed intake (FI) and feed conversion rate (FCR). In analysis of the crude proteins and fatty acid composition in leg and breast meats in control, GR 0.10% and GR 0.50%, there was no significant difference for crude proteins and fatty acid composition in leg meats among 3 groups. Whereas the crude proteins and fatty acid composition in breast meat in GR 0.50% showed significantly higher than those of control (P<0.05). Furthermore, the composition of a-linoleic acid (C18:3n-3) and conjugated linoleic acid, which are known as anticancer and antioxidative fatty acids, are higher than those of control. These results demonstrate that Galla Rhois appears to improve growth performance, feed efficiency and meat quality on broiler chickens, focusing on potential use as a dietary supplement.
