14-Apr-2010 (16 years 1 months 24 days ago)An experiment was carried out to evaluate performance, vulvae morphology, visceral organs and reproductive tract weight in pre-puberal gilts fed diets containing aflatoxins or zearalenone during 28 days. Eighteen animals with an average initial weight of 11 kg were used. Three treatments (control diet - CD; CD+1 mg/kg of aflatoxins; CD+ 2 mg/kg of zearalenone) were utilized in a completely randomized design with six replications.
Feed intake, weight gain and final live weight were reduced (p<0.05) by 30% (CD x CD aflatoxins: 1.087 x 0.758 kg), 27% (0.608 x 0.441 kg) and 16% (27.4 x 22.9 kg) for animals fed diets containing aflatoxins. Feed intake (CD x CD zearalenone: 1.087 x 0.986 kg), feed conversion ratio (1.85 x 1.86) and final live weight (27.4 x 25.5 kg) were not affected (p>0.05) by zearalenone in comparison to control group. The relative weight of liver and heart were not altered (p>0.05) by mycotoxins. However, zearalenone increased (p<0.05) the bulk of vulva, the length and weight of reproductive tract. Feeding diets with aflatoxins or zearalenone prejudices performance and stimulates estrogenic effects in gilts.
