Aim:The aim of this study was to evaluate the impact of therapeutic and high doses of florfenicol on kidney and liver functional indicators in goat species.Materials and Methods:Six mature, healthy goats (combine breed and sex) with average weight 25 kg were selected for this study. The therapeutic (20 mg/kg b.w.) and high doses (40 and 60 mg) of florfenicol were administered for 3 days with 24 h interval. Blood samples were collected at 0, 24, 48, 72, 96, and 120 h following the each administered dose.Results:The results showed that the therapeutic dose of florfenicol produced nonsignificant effect on serum urea, creatinine, total protein (TP), alkaline phosphatase (ALP), gamma-glutamyl transferase (GGT) and bilirubin on all timings, and increased (p<0.05) the serum glutamic oxaloacetic transaminase (SGOT) and serum glutamate-pyruvate transaminase (SGPT) levels for 48 h. Whereas the high doses of florfenicol (40 and 60 mg) significantly altered the kidney and liver functional indicators in the blood. In contrast with control, the serum urea level was (p<0.01) increased at all timing points. Creatinine values were altered (p<0.01, <0.05) in increasing manner from 24 to 96 h. The high dose of 40 mg decreased the TP (p<0.05) for 72 h and 60 mg persisted same effect (p<0.01) up to 120 h. The indices of ALP, GGT, SGOT, and SGPT were raised (p<0.01, <0.05) at all timings. The bilirubin indexes also (p<0.05) elevated from 48 to 72.Conclusion:It was concluded that the high doses of florfenicol produced reversible dose-dependent effects on functional indicators of kidney and liver such as urea, creatinine, TP, ALP, SGOT, SGPT, GGT, and bilirubin.
We examined whether surplus dietary selenium (Se) supply could alleviate high concentrate (HC) diet‐induced hepatic oxidative stress (OS) and inflammation. Eighteen young goats were distributed into three groups; were fed low (LC, concentrate: forage; 35: 65), high concentrate (HC, 65: 35), or Se‐supplemented HC (HCSe, 65: 35 + 0.5 mg Se kg−1 diet) diets for 10 weeks. Short chain fatty acids, OS markers and immunoinflammatory genes expressions were assessed through gas chromatograph, kits, and RT‐qPCR, respectively. Compared with LC, HC diet increased (p < .05) colonic and serum lipopolysaccharide (LPS) levels and induced hepatic oxidative injury by increasing (p < .05) malondialdehyde (MDA) levels and decreasing (p < .05) activities of glutathione peroxidase, superoxide dismutase, and catalase. HC diet altered hepatic mRNA expressions of toll‐like receptor‐4 (TLR‐4), cluster of differentiation‐14 (CD‐14), tumor necrosis factor‐α (TNF‐α), TNF receptor‐associated factor‐6 (TRAF‐6), nuclear factor kappa B (NF‐κB), interleukin‐1β (IL‐1β), IL‐10, IL‐13, LPS‐binding protein (LBP), serum amyloid A (SAA), α‐acid glycoprotein (AGP), and albumin (ALB). Conversely, extra‐Se supply lowered LPS and attenuated antioxidant status and inflammation in liver. In conclusion, HC diet induced oxidative lesions and TLR‐4 pathway‐mediated inflammation, whereas supranutritional Se alleviated oxidative and inflammatory lesions through TLR‐4 pathway regulation in goat liver.
