Usefulness of certain clinical observations and blood chemistry values (BHBA, glucose, ions and blood gases) for predicting clinical outcomes when treating dairy goats with pregnancy toxemia
| Resumo: | Pregnancy toxemia (PT) is a disease characterized by a high case fatality rate (75% in this study). Clinical signs and blood chemistry values from 32 cases of PT in goats are described and summarized. Polypnea, swollen limbs, anorexia and absence of ruminal motility, sternal recumbency but ability to rise upon stimulation, neurological signs and drooped ears were the most consistently observed clinical manifestations. A decision concerning whether or not to and/or how to attempt to treat a PT goat should be based on clinical signs and blood parameters. The clinical signs most indicative of a poor prognosis are anorexia and recumbency; among the blood parameters it is potassium (K+) and those indicative of a metabolic acidosis, namely pH, pCO2, bicarbonate (HCO3-), base excess (BE), as there was a statistically significant difference between the goats that died and the goats that survived. Beta-hydroxybutyric acid (BHBA) values were not significantly different between the goats that died and the goats that survived. In conclusion, the clinical observations and the blood parameters described are likely to be used as prognostic indexes for dairy goats with PT. It should also be remembered that the prevention is of crucial importance in large flocks. |
