Unusual turns of the conical colon of swine

Anomalous arrangements of the conical colon were found in 38 cases out of 731 swine. These anomalies divided into the following five types: 1) additional loop running perpendicular to the turns (8 cases), 2) two or four changes in the centripetal turns (6 cases), 3) two changes in the centrifugal turns (2 cases), 4) one to three changes in both the centripetal and centrifugal turns (21 cases), and 5) two independent conical colons (1 case). The double conical colon (Type 5) was the only one case and seems to be rare. The total of the anomalous types made up approximately 5.2% and not appear to be rare.
