Abstract
Aim: To assess effects of the toxicity caused by consuming the fungal contaminated fodder by the cattle in the field conditions.
Study Design: Study was conducted in 3 groups of Wistar Albino rats.
Place and Duration of Study: Department of Veterinary Pharmacology and Toxicology and Department of Veterinary Pathology, Veterinary College Shivamogga, Karnataka, between August 2024 to October 2024.
Methodology: A repeated-dose 28-days oral sub acute toxicity study was performed with three groups (n=6) of Wistar Albino rats. The group I (control) received oral gavage of potato dextrose broth @ dose of 2 mL/100g, where as groups II and III received mixed fungal culture filtrate of Aspergillus flavus and Aspergillus niger at the doses of 1 and 2 mL/100 g respectively.
Results: Treated groups (group II and III) showed increase in serological parameters (Aspartate Transaminase, Alanine transaminase, Creatinine, Blood urea nitrogen) and decrease in hematological parameters (PCV, Hb, TLC, TEC).
Conclusion: The findings of the present study inferred that the fungal culture filtrates of fungus isolated from contaminated maize stalk caused toxicity in rats, which was attributed for the presence of a toxic principle components in the fungal culture filtrates.
