Avaliação da proteína total e peso relativo do fígado de frangos de corte suplementados com ácidos orgânicos e desafiados com aflatoxinas, fumonisinas e deoxinivalenol

Abstract

Fungal contamination in rations is considered an obstacle to poultry production, some filamentous fungi species produce toxic metabolites known as mycotoxins, which have important toxic mechanisms, leading to impairment of the function of several organs, interfering with hematology in the biochemical profile and causing relative increase in organ weight from challenged animals. To inhibit the development of fungi in the diets, the use of organic acids is considered as an alternative form to be added to the diet of broilers. The present study aimed to evaluate the total protein and relative liver weight of broilers challenged with mycotoxins and the effect of different organic acids added to the basal diet. For the experiment, 1296 male broilers were used, distributed in 6 treatments, all groups were challenged with a set of mycotoxins at concentrations of 0.15mg/kg of aflatoxins +50.0mg/kg of fumonisins + 25.0mg /kg deoxynivalenol, except negative control. Organic acids were distributed among the treatments, where T3 received the addition of products (A, B, C), T4 (A, B), T5 (B, C) and T6 (C), with products A and B added in the ration and the C added to the water The results of the work demonstrate that at 42 days, broilers challenged with mycotoxins and that received the inclusion of organic acids had higher serum levels of total proteins than the negative control. It can also be observed that the inclusion of mycotoxins during this period did not affect the relative weight of the liver. The conclusion of the present study attributes the relative increase in serum total protein concentration to the inflammatory response and the addition of organic acids did not prevent this process. It is also concluded that the concentrations of the doses used of mycotoxins do not interfere with the relative weight of the liver.
