The current study proposes anatomical changes in the digestive system of 120 Akar Putra chicken after surgical removing of auropygial gland. The experiment comprised of five treatments (24 chicken/treatment), with 3 replicates (8 chicken/replicate). The experimental treatments consist of a control treatment T1; partial ablation of the uropygial gland were applied on T2, T3, T4 and T5 treatments at 3, 4, 5 and 6 weeks of age respectively. The results presents that Partial Uropygialectomy (PU) treatments in males had (p<0.01) longer esophagus 9.9-16.2%, proventriculus 11.1-34.4%, gizzard 26.7-220%, pancreas 0-20.4%, jejunum 4.9-26.1 and colon 18.1-60.6 than the control group counterparts. Furthermore, females of PU treatments had (p<0.01) longer esophagus 6.8-22.3%, pancreas 8.3-33.3% and cecum 13-26% compared with females in control. In contrast, total GIT weight were 21.2 to 78.8% heavier (p<0.01) in males of PU treatments, mainly in the esophagus, duodenum, pancreas, jejunum, ilium and cecum. No significant impact (p>0.05) between treatments was recorded in the total females’ Gastrointestinal Tract (GIT) weight; however, females of PU treatments had 5.9-41.2% heavier ilium (p<0.01) and 11.1-77.8% heavier cecum (p<0.01). Total GIT density, show no significant different (p>0.05) between treatments in females. Nevertheless, it was highly significant different (p<0.01) for males of PU treatments, mainly in esophagus (p<0.05), gizzard (p<0.05), pancreas (p<0.01) and cecum (p<0.05). In conclusion; the results of current study investigated that partial ablation of the uropygial gland had positive effects on the anatomical observations of most digestive system parts.
