• Pregnancy toxaemia

Eleven Murciano-Granadina goats in late pregnancy were separated into two groups (1) control (n = 6) and (2) fasting for 72 h to induce pregnancy toxaemia (n = 5). Venous blood was taken daily to determine acid-base and electrolyte parameters. Significant decreases in blood pH, bicarbonate concentration and base excess, and a significant increase in anion gap were observed after 24 h of fasting. These changes were significantly correlated with non-esterified fatty acid concentration. No significant changes were observed in pCO(2), and electrolyte or lactate concentrations. Clinical signs of pregnancy toxaemia in fasted goats appeared by 72 h post-fasting. These signs and the changes in acid-base balance disappeared once feed was reintroduced. Blood pH, bicarbonate concentration, base excess and anion gap could be indicators of early pregnancy toxaemia in goats.
