This experiment was conducted to evaluate levels of inclusion of zeolite in diets for growing-finishing pigs on performance, feed intake, carcass characteristics, blood and hepatic parameters and the bone concentration of calcium and phosphorous. Eighty four barrows from commercial hybrids of high genetic potential for meat deposition, with 70 days of age and initial weight of 30.34 ± 1.14 kg were distributed, on the basis of weight, in randomized blocks design, with seven sequences levels of adsorbent (0.0-0.0; 1.0-0.5; 1.0-1.0; 2.0-1.0; 2.0-2.0; 3.0-1.5 and 3.0-3.0, respectively, on growing phase and finishing phase), six replicates with two animals per pen, which was considered the experimental unit. The experimental diets for the growing (70 to 105 days) and finishing (106 to 135 days) phases were formulated with corn, sorghum and soybean meal, supplied with minerals, vitamins and amino acids. The sorghum was used as naturally contaminated source of mycotoxins. The different levels of adsorbent in the diets were obtained by the supplementation of zeolita in the basal diet. The inclusion of zeolite in the diet did not affect the daily feed intake, daily weight gain, feed conversion and the carcass characteristics of the pigs. In the same way blood and hepatic parameters and the bone concentration of calcium and phosphorous were not affect by the different levels of zeolita. Due to the good performance and carcass characteristics as well the normality of the others analyzed parameters of the animals fed the diets without adsorbents, it can be inferred that the diets had low levels of mycotoxin contamination. It can be concluded that the levels of zeolite do not affect the performance, feed intake, carcass characteristics, blood and hepatic parameters and the bone concentration of calcium and phosphorous in growing-finishing pigs fed diets with low level of mycotoxin contamination.
