Could Different Eubiotics Improve Gut Health, Growth Performance, Carcass Yield, and Skin Pigmentation in Broilers...

The objective of this research was to evaluate different commercial eubiotics. The eubiotics were evaluated individually and in combination on growth performance, carcass traits, and gut structure in broilers fed sorghum-soybean meal diets. A total of 1000 Ross 308 male broilers were randomly allocated to one of five dietary treatments with eight replicates of 25 broilers each. The experimental treatments were: 1. CON (basal diet), 2. ENR (basal diet + Enradin^® 100 g/ton), 3. PF (basal diet + Probion-forte© 300 g/ton), 4. PF+ EB (basal diet + Probion-forte© and EndoBan FT^® 250 and 250 g/ton, respectively), 5. CPP (basal diet + CRINA^® Poultry Plus 300 g/ton). Broilers fed with eubiotic-supplemented diets showed significantly ameliorated growth performance compared with the control group (CON p < 0.05). Carcass weight was also significantly higher in broilers fed with eubiotics than those fed CON (the basal diet, p < 0.05). Gut structure analysis showed an increased villus height and mucosal thickness in the duodenum of eubiotic-treated groups (p < 0.05). The mixed supplementation of Probion-forte© and EndoBan^®(PF-EB) induced greater villus height and mucosal thickness in the jejunum and ileum (p < 0.05). Additionally, supplementation with PPR (CRINA^® Poultry Plus) increased crypt depth in the duodenum and jejunum (p < 0.05), whereas PF (Probion-forte©) improved the villus height-to-crypt depth ratio in the duodenum and ileum (p < 0.05). Consequently, dietary supplementation with these commercial eubiotics, individually and in combination, could ameliorate productive performance, carcass yield, skin pigmentation, and gut structure in broilers.
