Abstract
This experiment was conducted to evaluate the effects of dietary Hwangto on growth performance and body composition in broiler chicks. A total of 216 one-day old 'Ross' broilers were assigned to 6 treatments in a completely randomized design. The six dietary treaoents were control no Hwangto added and diets containing 0.5, 1.0, 2.0, 4.0 and 8.0% of Hwangto supplementation. The weight gain of broilers tended to reduce with increasing level of Hwangto. However, there were no significant differences in feed intake and feed conversion ratio of broilers fed control and diets containing different level of Hwangto supplementation (P>0.05). There were no significant differences in TBA value of meat from broilers fed control and Hwangto supplemented diets (P>0.05). The meat cholesterol content was significantly lower in Hwangto treatment than of the control (P>.0.05). $NH_3$ concentration in feces was reduced in all Hwangto treatments (P<0.05). The Mg and Mn concentrations of meat we.e significantly higher in 8.0% Hwangto treatment than that of the control (P<0.05). The large intestine weight was significantly reduced in 2.0, 4.0 and 8.0% treatments (P<0.05).
