Rious well being threat connected with milk consumption. Hence, we seek to offer an integrative insight in to the exploration of AFB1 degradation inside the rumen, AFB1 biotransformation inside the liver, secretion of AFM1 in milk, in order to illuminate the metabolic profile of AFB1 and its biotransformation into AFM1 in dairy cows. A comprehensive understanding of this method and precise regulating methods combined with prevention and detoxification techniques might minimize the threat of AFM1 contamination of dairy milk.L.

Biotransformation and metabolic profile of AFB1 in dairy cows four.1. Degradation of AFB1 within the rumen Ruminants have a diverse and complex microbiome within the rumen where ingested feeds are digested and fermented. The role in the rumen within the metabolism of AFB1 consists of microbial and microbial enzymatic degradations, thereby converting AFB1 into AFB1 metabolites (Upadhaya et al., 2010). Even though previous studies indicated that ruminants are normally additional resistant to aflatoxicosis (adverse animal overall health effects) than non-ruminant animals (Kiessling et al.
