Transfert et métabolisme des hydrocarbures aromatiques polycycliques chez le ruminant laitier

Abstract : Polycyclic Aromatic Hydrocarbons (PAHs) are lipophilic, persistant and ubiquitous compounds in the environment. Exposed fodder becomes a PAHs route for lactating ruminants. A first experiment was aimed to evaluate the influence of feeding system on PAHs levels in cows' milk. The results showed that grass generals a more important PAHs exposition than maize fodder. A second experiment was focused on PAHs transfer from feed to milk in controlled conditions. Among the 16 PAHs of the US-EPA list, only light compounds with less than 5 aromatic rings were detected in milk. Their transfer levels decreased from 30 % to 1 %.
