The Federation of European Societies on Trace Elements and Minerals (FESTEM) organised its 7th International Symposium last April in Postdam (Germany), like every three years. A presentation from Animine highlighted the large variation in bioavailability of feed grade zinc oxide sources. Indeed, in a study performed at INRA (Nouzilly, France), bioavailability of zinc sulfate and 4 representative sources of zinc oxide were tested on 135 broilers raised in individual cages. While regular zinc oxide products had lower or similar bioavailability than zinc sulfate, HiZox®, a potentiated form of zinc oxide, showed higher bone zinc values than zinc sulfate (+52%). These results which confirmed previous study performed under scientific supervision of INRA (European Symposium on Poultry Nutrition 2015), can be explained by the unique physicochemical properties and the optimal biosolubility of HiZox®.
