Fimbria-fornix transected animals (FF), sham-operated animals (Sham), and two non-operated control groups with and without administration of buprenorphine (+BUP and −BUP, respectively) were observed twice daily for seven days after surgery. Buprenorphine (0.4 mg/kg) mixed in a nut paste for voluntary ingestion was supplied twice daily for 84 h to all groups except the −BUP control group starting on the day of surgery. Body weight was slightly decreased postoperatively in both surgical groups (FF and Sham) compared to control groups. The +BUP control group lost weight starting at day four after discontinuation of buprenorphine. Furthermore, the FF group exhibited significantly reduced general condition one day after surgery, with significantly affected body posture and movement for two days after surgery. In addition, mild pica behavior was observed in the FF group during the first postsurgical day. In conclusion, the FOB implemented in the present study appears to be a sensitive and accurate protocol for assessing animal well-being in the experimental setup applied. It is apparent that the FF transection is an invasive procedure that causes mildly adverse postoperative effects on the rats' well-being. We therefore recommend that this FOB is applied as a routine welfare monitoring protocol in experiments using mechanical central nervous system injury models, such as FF transection. ER -
