Therefore, the present study aimed to evaluate the accuracy of the human portable sensor and the veterinary portable sensor for the determination of beta-hydroxybutyrate (BHB) in sheep at the end of gestation and postpartum. We used 37 samples of blood from nine crossbred Corriedale sheep. Biochemical determination of serum BHB, considered gold standard, was performed using colorimetric enzymatic methodology. The mean serum biochemistry was 0.497mmol/L, in the human sensor the mean was 0.537mmol/L, while in the veterinary sensor it was 0.751mmol/L. A high correlation was verified between the dosimeter for human use and the gold standard (r= 0.93, P< 0.001). The mean of the veterinary apparatus differed from the others, being 51% (P< 0,05), higher than the standard, that is, it was less accurate and had lower veracity, overestimating the results in sheep. It was concluded that the portable sensor for human use is more accurate and accurate in the early diagnosis of toxemia of pregnancy in sheep.</p><p></p> 2019-07-10 02:47:20 ketosis pregnancy toxemia accuracy diagnosis
