Abstract
Mycotoxin contaminations in poultry feed have been the second major stumbling
block in feed industry after increasing price of conventional feedstuff. Among over
300 mycotoxins identified, aflatoxins B1 have been a main concern for animal
nutrionist, particularly in tropical regions. The use of mycotoxin binders to replace
fungicide or mold killer has been long practiced in poultry diet. An experiment
was conducted to determine the effect of mannan-polysaccharides extracted from
copra meal in an attempt to bind mycotoxin in broiler diets. Three hundred broiler
chicks were used and were allocated to treatment diets in brooder cages from days
1 to 14. On days 15, eighty birds were transferred into the individual metabolism
cages for faecal collection and digestibility studies. The rest of the birds were then
allocated into floor cages for the bird performance parameters. The treatments diets
were: (1) control diet, (2) control diet + 0.10% bentonite, (3) control diet + 0.02%
yeast mannan, (4) control diet + 0.02% copra mannan (CM) and (5) control diet +
0.05% CM. The diets were mixed with or without aflatoxin B1. The feeds and water
were offered ad-libitum. Total faecal collection was done for three consecutive

days for digestibility measurements. A completely randomized factorial design was
used to test the effect of 5 diets in the presence of two levels of aflatoxin B1 on
bird performance by using 4 replicate cages. Coefficient of feed digestibility was
significantly improved due to diet treatments where contaminating the feed with 0.3
ppm aflatoxins B1 impaired feed digestibility. There was an interaction between diet
treatments and level of aflatoxins B1 in coefficient of feed digestibility (P
