Effect of dietary supplementation with natural zeolite and nano-zeolite on gut flora, tibia bone characteristics and performance of broiler chickens

Effect of natural zeolites and nano-zeolite on gut flora, tibia bone characteristics, blood parameters and performance of broilers investigated with 336 male Ross 308 broilers chicks allocated to seven treatments with four replicates and 12 chicks per each. Experimental treatments were control (no zeolite supplemented), natural zeolite (0.5, 1 and 1.5 percent) and nano-zeolite (0.5, 1 and 1.5 percent). Experimental diets had no significant effect on relative weight of breast, thights, liver, abdominal fat, gizzard and carcass efficiency. Zeolite and nano-zeolite supplementation led to significant decrease of total bacteria and E. Coli population (P
