Abstract
the present study was conducted to investigate the effects of dietary acidification supplement on performance and biochemical parameters of quail chicks. 400 one-day old Japanese quail chicks (mixed sexes) were randomly assigned in a completely randomized design with 4 treatments. Each treatment group consisted of 5 replicates of 20 birds. Treatments included 1- basal diet (control group), 2- basal diet+300 mg / kg virginiamycin, 3- basal diet+ 0.2% Bio acid ultra, 4- basal diet+ 0.4% Bio acid ultra. The results showed that the length and the thickness of villi, and the depth and the thickness of the crypt in the various parts of the intestine including duodenal, jejunum and ileum in the antibiotic supplemented quail were reduced and adding acid at both levels of 0.2% and 0.4% to the diet caused a significant increase in these values (p
