Influence of the breed on volemia and renal function in cattle with experimentally induced acute rumen lactic acidosis
Keywords:Cattle, Jersey, Gir, Lactic acidosis, Volemia, Renal function
AbstractTo study volemia and renal function in cattle with acute rumen lactic acidosis (RLA) five Jersey (J) (Bos taurus) and five Gir (G) (Bos indicus) steers were used. Blood, urine and ruminal fluid samples were collected throughout 24h after RLA induction. Higher levels of hipovolemia (p < 0.00001), and total rumen volume (p < 0.05), lower glomerular filtration (p < 0.003) and urinary volume (p < 0.05) were detected in the G steers. Nevertheless, these steers excreted more efficiently H+(p < 0.0001); although higher urinary D-lactate fractional excretion was seen in the G steers similar amounts of D-lactate were excreted by both breeds throughout the trial. Lower urinary levels of L-lactate were excreted by G steers. The higher the urinary pH, the lower the D-lactate fractional excretion in both breeds.
