Abstract: The aim of the present study was to investigate the influence of different growth promoters on broiler performance and intestinal morphology reared under various stocking densities. A total of 900 day old (Ross-308) straight run broilers were randomly divided into fifteen treatment groups according to a completely randomized design. A 5 × 3 factorial arrangement of treatment was employed. Treatments were consisted of four growth promoters (antibiotics, prebiotics, probiotics, and symbiotics) and a control grou… Show more

“…Through competitive exclusion and bactericidal activity, probiotics suppress the proliferation of harmful bacteria such as Escherichia coli and Salmonella in the gastrointestinal tract resulting in the healthier guts of broilers during the rearing at HSD (Khalil et al, 2021;Ebeid et al, 2019). Probiotic treatment was also reported to improve the intestinal morphology of broilers raised at a HSD, i.e., increased intestinal villi height and villus-to-crypt ratio (Altaf et al, 2019;Ebeid et al, 2019). In addition to the lowered corticosterone levels and improved intestinal bacterial populations (Khalil et al, 2021;Ebeid et al, 2019), probiotics promote the synthesis of short-chain fatty acids, which is beneficial to the development of intestinal cells and tissues of overcrowded broilers (Altaf et al, 2019).…”

“…On the 35th day, 3 birds per replicate were randomly picked up and slaughtered by the halal method (Altaf et al, 2019). Ileum samples were obtained for intestinal morphology to determine the height of the villus (µm), crypt depth (µm), andthe ratio of the villus to crypt (Giannenas et al,2012).…”
