HAUSCHILD, Luciano et al. Digestibility and metabolism of piglet diets containing zearalenone with addition of organoaluminosilicate. Pesq. agropec. bras. [online]. 2007, vol.42, n.2, pp.219-224. ISSN 0100-204X.

An experiment was carried out to asses diet digestibility and metabolism balance of piglets fed on diets containing zearalenone (ZEA) with and without addition of organaluminisilicate (OA). Twelve gilts littermates were used, with 12 kg initial body weight, housed in metabolic cages. A completely randomized design was used and comprised three treatments (control, control + 2 ppm ZEA, and control + 2 ppm ZEA with addition of 0.3% of OA), and four replications, being the animal as experimental unit. The ZEA and the OA did not affect (p>0.05) dry matter intake, digestibility of dry matter and gross energy, metabolizable energy, digestible energy as well as digestible protein. The nitrogen balance was not modified (p>0.05) by ZEA and OA. However, it influenced (p<0.05) the fecal excretion of P. In diets containing ZEA and ZEA+OA, fecal excretion of P was 15 and 10% lower than the control group. The ZEA and the OA did not affect (p>0.05) the absorption of P in relation to the ingestion. The intake of 2 ppm of ZEA with or without addition of 0.3% of OA in diet does not affect the digestibility of diets and the metabolism of pigs.
