From: Residues of chlortetracycline, doxycycline and sulfadiazine-trimethoprim in intestinal content and feces of pigs due to cross-contamination of feed

Fig. 2

Concentrations of A) chlortetracycline (CTC), B) doxycycline (DOX) and C) sulfadiazine (SDZ) in cecal content and colonic content from three different sampling segments (6 indepentent observations per sampling segment). Samples were taken from 6 pigs per group after 10 days of ad libitum feeding with feed containing 3 % cross-contamination levels of CTC, DOX and SDZ. Mean concentrations in caecum (CM), proximal colon ascendens (PCA), distal colon ascendens (DCA) and colon descendens (CD) were 6.95, 8.41, 7.12 and 10.08 mg/kg (CTC), 1.78, 3.31, 2.68 and 3.81 mg/kg (DOX) and 0.47, 0.45, 0.67 and 0.54 mg/kg (SDZ), respectively. The two outlying values for CTC (observation 9 and 15) belong to one animal. A different letter (a or b) denotes a significant difference in concentration between sampling segments (p < 0.05)
