A total of 2400 broiler chicks were randomly divided into five different treatment groups, with six repetitions per treatment, and raised from day 1 to 33. No significant differences were seen between dietary treatments for heart, liver, spleen and bursa weights, as well as gizzard erosion. Gizzard weight for the Ateli plus® max supplemented broilers was significantly higher than the negative control broilers. The pH of the duodenum, jejunum, ileum, proventriculus and caecum were measured within 15 minutes post-mortem, with no significant differences between dietary treatments. Duodenum, jejunum and ileum villi height and crypt depths were measured. Duodenum villi height was longest for broilers supplemented with antibiotic diet (AGP), and shortest for broilers supplemented with Ateli plus® min and AGP plus Ateli plus® treatment, with crypt depth being the longest for Ateli plus® min supplemented broilers. Broilers fed the basal treatment (negative control) had the shortest jejunum villi height and crypt depth. Ateli plus® max supplemented broilers had the longest jejunum villi length, while crypt depth was longest in AGP supplement broilers. Ileum villi height and crypt depth was longest for AGP supplemented broilers, and statistically shorter and equal for the remaining dietary treatments. Broilers fed plant extract supplemented diets showed no significant improvement in villi height to crypt depth ratio. No significant effect of plant extracts on gut morphology or organ health can be concluded from this study. _____________________________________________________________________________________________Read More
