This study was conducted to evaluate the alleviative effects of activated charcoal (AC) and Houttuynia cordata (HC) singly or in combination in broiler chickens during aflatoxicosis. Activated charcoal (1% or 0.5%) and H. cordata (1% or 0.5%) were mixed into the diets for the ability to reduced the deleterious effects of 2.4mg total aflatoxin (AFB₁) kg-¹ diet on growing broiler chickens from 1 to 21 days of age. A total of 160 1-day-old (Hyline Variety Brown) broiler chicks were housed in eight treatment groups [Control, AFB₁, AC 1%, HC 1%, AFB₁ plus AC 1% plus HC 1%, AFB₁ plus AC 1% plus HC 0.5%, AFB₁ plus AC 0.5% plus HC 1%, AFB₁ plus AC 0.5% plus HC 0.5%] each consisting of 20 chicks. Compared to control, 2.4mg AFB1 alone treatment group significantly decreased body weight gains of chickens. The addition of mixed AC 1% and HC 1% including 6, 7 groups to the 2.4mg AFB₁-containing diet moderately reduced the adverse effects of AFB₁ on performances of chickens. The chickens consuming 2.4mg AFB₁plus AC 0.5% and HC 0.5%-containing diet showed very slightly reduced the adverse effects on investigated parameters compared to the AFB₁ only treated group. Also, the single addition of AC or HC to the AFB₁-free diet had no adverse effects in chickens. These results suggest that AC and HC mixed can reduced the aflatoxicosis in broilers and may be contribute to a solution of the aflatoxicosis problem in poultry production.
Abstract
This study was conducted to evaluate the alleviative effects of activated charcoal (AC) and Houttuynia cordata (HC) singly or in combination in broiler chickens during aflatoxicosis. Activated charcoal (1% or 0.5%) and H. cordata (1% or 0.5%) were mixed into the diets for the ability to reduced the deleterious effects of 2.4mg total aflatoxin (AFB₁) kg-¹ diet on growing broiler chickens from 1 to 21 days of age. A total of 160 1-day-old (Hyline Variety Brown) broiler chicks were housed in eight treatment groups [Control, AFB₁, AC 1%, HC 1%, AFB₁ plus AC 1% plus HC 1%, AFB₁ plus AC 1% plus HC 0.5%, AFB₁ plus AC 0.5% plus HC 1%, AFB₁ plus AC 0.5% plus HC 0.5%] each consisting of 20 chicks. Compared to control, 2.4mg AFB1 alone treatment group significantly decreased body weight gains of chickens. The addition of mixed AC 1% and HC 1% including 6, 7 groups to the 2.4mg AFB₁-containing diet moderately reduced the adverse effects of AFB₁ on performances of chickens. The chickens consuming 2.4mg AFB₁plus AC 0.5% and HC 0.5%-containing diet showed very slightly reduced the adverse effects on investigated parameters compared to the AFB₁ only treated group.

These results suggest that AC and HC mixed can reduced the aflatoxicosis in broilers and may be contribute to a solution of the aflatoxicosis problem in poultry production.
