Could Fibrinogen Concentration Be a Useful Indicator of Cattle Herd Health Status? Approaches to Setting Reference Values

Fibrinogen is used in the diagnosis of inflammation as an acute phase protein. The research objective set by authors this study was to assess applicability fibrinogen concentration measurement blood plasma peak lactating dairy cows through evaluation reference values using functional PT-derived (Prothrombin Time-derived) method. Materials and methods: carried out on 259 HF (Holstein-Friesian) white-backed cows. animals were clinically healthy. determined automated concentrations calculated mean duplicate samples. Samples with differences between results greater than 5% rejected. Results: In group cows, average 11.75 ± 4.80 g/L. it 9.53 4.79 At total 76.01% 82.05% obtained within ±1 SD (Standard Deviation) range. Conclusions: Based our own research, method may be applied order determine cattle herds animal health monitoring studies. An individual laboratory should focus more verifying intervals established elsewhere.
