ROSSI, P. et al. Esterified glucomannan and organic selenium for broilers chickens fed diets contaminated with aflatoxins. Arch. zootec. [online]. 2013, vol.62, n.237, pp.33-43. ISSN 1885-4494.  https://dx.doi.org/10.4321/S0004-05922013000100004.

The objective of this study was to evaluate the effect of sterified glucomannan absorbent of mycotoxin and organic selenium add to corn-soy diets contaminated with aflatoxins on growth performance, carcass and cuts yield, and macroscopic lesions on visceral organs of broilers. A total of 784 broilers were subjected to a completely randomized block design, including 4 treatments and 7 replicate with 28 birds each treatment. Birds fed diets with aflatoxins and supplemented with glucomannan in combination with organic selenium, showed better weight gain and less macroscopic lesion. The use of glucomannan improved feed intake. Feed conversion, mortality, carcass yield and relative organ weight (except the liver) were not influenced by dietary treatments. These results indicate that diets with aflatoxins affect adversely growth performance, carcass characteristics and macroscopic lesion of broilers. However, the supplementation with sterified glucomannan in combination with organic selenium in diets with aflatoxins improves growth performance and decrease macroscopic lesion.
