The objective of this study was to evaluate the productive performance of broiler breeder hens fed diets containing aflatoxins and adsorbent on the basis of esterified glucomannan. It was used 300 Ross 308 females and 40 males broiler breeders, housed in 20 experimental pens in the 61-72 week of age phase. From the 61st to the 68th week, birds were fed diets containing three levels of aflatoxin (0; 0.500; 0.750 mg/kg) combined or not to adsorbent (0.10%) and on the last four weeks they received diets without aflatoxin and adsorbent. The birds were distributed in a complete randomized design in a factorial scheme (levels of aflotoxin vs levels of adsorbents) with 4 replicates, each one with 15 females and 2 males. From the 65th week, birds fed diets with aflotoxin and adsorbent showed lower laying rate compared to those fed regular diets, without those additives. Body weight of the breeders as well as egg weight, specific egg weight, hatchability and quality of chicks produced are not affected by the levels of aflatoxins and adsorbent present in the diet.
