The purpose of this research is to determine the relationship between cystatin C (Cys-C) and some hematologic and biochemical parameters in neonatal calves diarrhea. Materials and In this research the animal material of the study was obtained from different breeds, genders and ages (0-30 days) 10 samples have been taken from healthy neonatal calves and 22 samples from diarrhea calves which didn′t received any medicine. Otherwise, the general examination has been done for all the calves. The levels of hematologic, biochemical and blood gas have been determind for both healthy calves and neonatal calves diarrhea.Results: Depending on the control group, we have observed that the neonatal calves diarrhea hematologic parameters WBC, Neu, Hct, Hb levels (p<0.05) and biochemical parameter BUN (p<0.01) and Cr (p<0.05) level statistically have been increased. On the other hand, Alb (p<0.05) and glucose (p<0.01) levels have been decreased. In term of blood gas analysis and depending on the control group the level of K+ (p<0.05) has been increased, the levels of pH, pO2 and base (p<0.05) have been decreased. We evaluate the Cys-C level in the neonatal calves diarrhea and we have found that Cys-C level is statistically increased this was detected comparing to the control group (p <0.01).In this research the obtained level of Cys-C can be used as normal for calves; statistically there is no relationship between Cys-C and some of the hematologic and biochemical parameters, the Cys-C level in the calves diarrhea is an important parameter it can be used to determine the diagnosis, treatment and prognosis of the disease; but still much more research about the topic should be done.

In this case report, treatment of the proximal tibial fracture of a calf with a linear external fixator (orthofix) system was presented. Oblique fracture was diagnosed proximal to left tibia regarding the clinical and radiological findings. Following the routine preparatory steps for the operation, the extremity was suspended and the fracture was reduced with orthofix from the lateral side of the tibia under general anesthesia. After the operation, it was observed that the calf could functionally use the related extremity from the first day. The consolidation was completed on the 41st day, and the fixator was removed on 47th day. In conclusion, it was considered that the proximal tibial fractures of calves could be successfully treated with a linear external fixator.

Objective: Newborn calf diarrhea causes significant economic losses. Therefore, this study was aimed to determine the effect of adding probiotics on Total Antioxidant (TAS) and Total Oxidant (TOS) levels in routine treatment of calf diarrhea. Material-Method: The material of the study consisted of 12 calves, routine treatment (Group 1, n=6 calves) and probiotic group. (Group 2; n=6 calves).Results: TAS values increased statistically after treatment (P <0.05) in group 2 compared to pretreatment. Comparison of the groups after treatment revealed that TAS significantly increased (P <0.05) in group 2. While there was no statistical difference in TOS values between the groups a statistically significant increase (P <0.05) was detected after treatment compared to pretreatment.Conclusion: It was concluded that adding probiotics may be useful in addition to routine treatment in newborn calf diarrhea.
