A study was carried out to evaluate the efficacy of some phyllosilicate clays including a commercial adsorbent (Fix-A-Tox), two samples of bentonite and one sample of zeolite as inhibitor of aflatoxicosis in broilers. A total of 540 seven-day old broiler chicks with uniform average body of both sex were divided into six equal treatment groups including, group A: negative control (without aflatoxin and adsorbent), group B: 0,5 % Fix-A-Tox + 200 ppb aflatoxin B1, group C: 1 % bentonite BFH + 200 ppb aflatoxin B1, group D: 1 % bentonite B + 200 ppb aflatoxin B1, group E: 1 % zeolite + 200 ppb aflatoxin B1, group F: positive control (with 200 ppb aflatoxin B1 without adsorbent). This study was conducted to assess the production parameters with respect to serum biochemical parameters, relative weight of internals organ and carcass trait changes in chicks fed by one of the six diets. Addition of adsorbents in the diets containing aflatoxin significantly diminished the inhibitory effects of aflatoxin on body weight gain, feed intake and FCR, in all three periods of starter, grower and finisher, in that manner some of adsorbents were capable from prevention of negative effects of aflatoxin as extent as without toxin control diet. The most and the least feed intake was related to A and F diets respectively (p0,05). With exception of two diets of D and E in finisher period, other diets in all three periods had significant difference with together (p0,05). From stand point of gain, also A diet had the most and F diet had the least body weight gain (p0,05). Only in the finisher period diet A with B and diet D with E had no significant difference, but other diets in other periods had significant difference from stand point of gain. The maximum (the most bad) feed conversion was related to F diet that had significant difference with other diets. The serum concentrations of glucose, urea, ceratinine, uric acid, cholesterol, triglyceride, phosphorus and albumin were decreased in chicks fed with diet F but addition of adsorbents to diet (B to E diets) increased content of determined serum parameters. The relative weights of liver, heart, spleen, pancreas, proventriculus, gizzard and deodenum decreased, whereas relative weight of bursa was increased in negative control diet (without aflatoxin) and diets B to E (including adsorbents) compared to the positive control diet (containing aflatoxin). Addition of adsorbents to diet improved carcass traits of chicks fed with diet containing 200 ppb aflatoxin B1.
