The effects of probiotics protexin and aquablend avian antibodies on the intestine tissue of broilers

This study was conducted to investigate the effect of Protexin probiotic and aquablend antibody on the intestinal histology characteristics of broilers. In this experiment 320 day-old male broiler chicks of the Ross 308, with 5 treatments and 4 replications in a completely randomized design were distributed in experimental units (cages). The treatments include: control (C), Protexin(P1), Protexin(P2) with double there commended dose, Aquablend(A1) and Aquablend(A2) Aquablend twice there commended amount. The results showed that consumption of different dose of Protexin probiotic and aquablend antibody had significant effect on width of duodenal villus, height of epithelial tissue of the duodenum, depth of jejunum crypt, length of ileal villus, height of the ileum epithelial tissue and length of villus to depth of duodenal crypt of broilers(p<0.05). According to results of this research, it seems that the using of Protexin probiotic and aquablend antibody was effective in improving performanceof broilers.
