Reduction Effect of Aflatoxicosis on the Growth Performance, Blood Protein and Lipid Concentration and Gastro Intestinal Bacterial Broilers Fed Nanozeolite

In other to evaluate the effect of different levels of Nanozeolite (NZ) to reduce aflatoxicocity in broilers، an experiment was conducted in a completely randomized design with 336 male Ross broilers with six dietary treatments and four replicates. Dietary treatments were a control corn-soy diet without aflatoxin (AF) and five other contaminated diets to 0. 5 ppm AF containing different levels of NZ (zero، 0. 25. 0. 5، 0. 75 and 1 percent). Birds were fed AF contaminated diet without NZ had significantly lower body weight gain and higher feed conversion ratio than the other dietary treatments (P<0. 05). Significant lower feed intake was found in broilers fed AF contaminated diet without NZ as compared to control diet during grower as well as whole periods of the experiment (P<0. 05). The utilization of NZ in broilers diets led to reduce of AF adverse effects on their performance. Feeding broiler diets by AF contaminated diet without NZ led to significant reduction of carcass yields as compared to control diet (P<0. 05). Broilers fed AF contaminated diet without NZ had significantly lower total protein، cholesterol، albumin and triglyceride serum concentrations as compared to control diet (P<0. 05). Adding NZ to AF contaminated diets led to increase these blood parameters. Although experimental treatments had no significant effect on total bacteria and lactobacillus populations، but adding NZ to contaminated diets without NZ led to decrease of total bacteria population and increased of lactobacillus population. Dietary treatments containing NZ had significantly lower coliform bacteria population than AF contaminated diet without NZ (P<0. 05).
