Complex toxin binder mycotox® ng influence on the hepatotoxic effect of aflatoxin B1 in experimental treated goslings

Abstract

Abstarct. The aim of the present investigation was to evaluate the effects of aflatoxin B1 and Mycotox NG applied either independently or together, on blood total protein, albumin, blood glucose, total bilirubin, triglycerides, cholesterol, enzyme activities of alanine aminotransferase (ALT), aspartate aminotransferase (AST), alkaline phosphatase (AP), gamma-glutamyl transferase (γ GT), lactate dehydrogenase (LDH) and changes in liver morphology. At the same time, the potential of supplementation of feed with a mycosorbent (Mycotox NG) was evaluated. Experiments were carried out with 40 1-day-old Toulouse geese from mixed sexes divided into one control and three treatment groups (n=10). Groups were as followed: Group I – control (0 mg/kg AFB1 not supplemented with Mycotox NG); Group II (0.5 g/kg Mycotox NG), Group III (0.5 mg/kg AFB1 ) and Group IV (0.5 mg/kg AFB1 and 0.5 g/kg Mycotox NG). In this study, commercially available geese of Toulouse strain were reared from day one to forty two days in the deep litter system of management and the birds were divided into four groups. Normal feed tested free of aflatoxin (AFB1 ), was given to the control (Group - 1). 0.5 g/kg Mycotox was supplemented with the feed to Group 2, Aflatoxin (0.5 mg/ kg feed) was supplemented with the feed to Group 3 and Mycotox Ng (0.5 g/kg feed) + 0.5 mg/kg feed AFB1 was supplemented with the feed to Group 4. The duration of the experiments was 42 days. The monitored blood chemical parameters were analysed on post treatment days 21 and 42. In birds treated only with AFB1, (group III) increased blood activities of studied enzymes. At the same time, blood total protein, albumin, cholesterol, glucose and triglycerides were reduced as compared to controls. The observed histopathological changes in the liver consisted in various extent of dystrophy (congestion, vacuolar and granular dystrophy, round cell proliferation, necrobiotic changes, hyperplasia of gallbladder epithelium). The addition of mycosorbent (Mycotox NG) to the feed of Groups IV reduced substantially the changes in blood chemistry and the severity and frequency of liver histological lesions. The addition of mycosorbent (Mycotox NG) to the feed of Groups IV reduced substantially the changes in blood chemistry and the severity and frequency of liver histological lesions.
