Effect of three different anti-mycotoxin additives on broiler chickens exposed to aflatoxin B1

The growth of filamentous fungi on food often causes, aside from its deterioration, the mycotoxin production which determines economic losses in poultry industry, such as decreased productivity and injuries on poultry's carcass. Adsorbents based on yeast cell wall from Saccharomyces cerevisiae,...
