Abstract
Mycotoxins are a worldwide hazard to animal feed and capable of deleterious effects on poultry. The present study aimed to evaluate the effects of an anti-mycotoxin feed additive on productive and reproductive parameters of breeder hens and roosters fed diets experimentally contaminated with zearalenone (ZEN). A total of 288 hens and 32 roosters (Cobb 500) were randomly distributed in one of four dietary treatments, with nine hens and a rooster per pen and eight pens per treatment: control (C); C + anti-mycotoxin (AM) additive; C + ZEN; and C + AM + ZEN. The trial lasted from 28 to 65 weeks of age. Egg production, egg quality, fertility, hatchability, and hatch rates of fertile eggs were evaluated, as were sperm morphology and abnormalities, and chick quality. ZEN inclusion did not affect egg production but had harmful effects on albumen, egg quality and weight, eggshell thickness, egg fertility and hatchability, and chick length and quality, compared to C, with this negative effect partially alleviated by AM inclusion. Both AM and ZEN, however, decreased spermatic concentration, without affecting sperm morphology or abnormality. The anti-mycotoxin additive effectively mitigated the deleterious effects of ZEN on reproductive parameters and egg quality indexes when fed to breeder hens.
