Abstract

A total of 1,296 broiler chicken were housed, distributed in a completely randomized design with 6 treatments and 6 repetitions. The treatments consisted of a control diet formulated with corn considered adequate and without the addition of adsorbent, a diet formulated with corn naturally contaminated with mycotoxin (CCM) and four diets formulated with CCM and added with different commercial adsorbents. At the end of the first week and at 21 days of age of the birds, it was observed that the control diet resulted in greater (p < 0.05) live weight and weight gain in relation to the inclusion of CCM. The relative weight of the liver was lower for the control group compared to the groups receiving a diet with CCM and CCM + ads D. The relative weight of the proventriculus and cloacal bursa was lower for the control group compared to those who received a diet with CCM + ads B and CCM + ads C. There was no significant effect (p > 0.05) of the diets on the analysis of serum biochemistry and the occurrence of fatty and hydropic degeneration in the liver of broilers. The use of adsorbents can mitigate the harmful effects of mycotoxins, however, these products have specific binding capacity to the type of mycotoxin present in food.

Highlights

Corn is one of the main ingredients of broiler feed, present in about 60% of starter animal feed, representing 65% of the metabolizable energy and approximately 22% of the protein in the starter phase (Guerre, 2016)
Corn naturally contaminated by mycotoxins samples showed extremely high levels for zearalenone used in the starter feed and fumonisin B1 and B2 in the samples of the grower and finisher feed
Fumonisin B1 and B2 were found in the control diet, which demonstrates the wide contamination of food with mycotoxins

Summary

Introduction

Corn is one of the main ingredients of broiler feed, present in about 60% of starter animal feed, representing 65% of the metabolizable energy and approximately 22% of the protein in the starter phase (Guerre, 2016). In this way, the quality of corn has a significant impact on the production cost, the zootechnical performance and the quality of the products originated from chicken. The presence of fungi in the food does not necessarily imply mycotoxin production, just as the toxin may be present in the food even in the absence of fungi (D’Mello & Macdonald, 1997; Guerre, 2016)
