Abstract:

The negative impact of multiple ascending doses of cefquinome (CFQ) on hematological and serum biochemical profile of horse unknown. The objective of this study was to evaluate the effect of multiple ascending doses of cefquinome (CFQ) in horses on the following hematological (WBCs, LYM, MON, GRA, RBCs, HB, HT, MCV, MCH, MCHC, RDW, and PLT) and biochemical parameters (ALB, ALP, ALT, AST, CH, CR, GGT, LDH, TB, TP, TRIG, and BUN). The study was performed on the sixteen mature horses (4.6 ± 2.1 years, 302 ± 38 kg). Four dosages of CFQ were applied as Group I; 1 mg/kg, Group II; 2 mg/kg, Group III; 4 mg/kg and Group IV; 6 mg/kg, and each animal received intravenously a total of 13 injections, administered every 12 h for 7 days. The hematological and biochemical parameters of horses were monitored on the before 0 day and 1, 3, 7, and 14 days after the administration of the first CFQ. No significant differences in serum biochemical parameters were found amongst the groups (p>0.05). Significant differences were found in certain hematological parameters (MONO, GRAN, RBC, HB, HCT, MCH, and PCT) amongst the groups (p<0.05) within the reference ranges. These results indicate that the administration of multiple doses of up to 6 mg/kg of CFQ in the horse had no clinically significant impact on the blood parameters measured.
