Global Nutrition tannin extract

Global Nutrition's Globatan is a tannin extract from sweet chestnut wood, Castanea sativa Mill. The product contains hydrolysable tannins, which have no anti-nutritional effects but instead, they form complexes with cells, cell structures, proteins, mineral and micro-organisms. In vitro trials show that Clostridium perfringens – which causes necrotic enteritis in poultry – is susceptible to tannins. The product had an inhibitory effect on all clostridium strains, even at low concentrations. Other trials have shown improved growth and feed conversion as well as drier litter.
