Relationships Between Concentrations of Biological Variables in Eye Fluids and Blood After Exercise in Lidia Cattle

Lidia cattle are a heterogeneous Iberian cattle population known for its natural aggressiveness and resistance to traditional handling procedures making in vivo blood sampling and biological fluid collections extremely difficult. Blood variables are influenced by physical exertion and stressful situ...

All plasma concentrations were clearly modified, however ocular fluids do not seem affected, thus establishing important correlations between the blood and intraocular fluids.González-Montaña José-RamiroEscalera-Valente FranciscoAlonso Marta E.Lomillos Juan M.Gaudioso VicenteSciendoarticleaqueous humorvitreous humorbiochemical variablesintraocular fluidsbloodmetabolismlidia cattleVeterinary medicineSF600-1100ENActa Veterinaria, Vol 68, Iss 4, Pp 420-433 (2018)
