  • Title: Severe prepartum ketosis in an obese beef cow.
    Author: Tyler JW, Dowling PM, Spano JS, McKnight AL, Wolfe DF.
    Journal: J Am Vet Med Assoc; 1994 May 15; 204(10):1665-7. PubMed ID: 8050951.
    Abstract:
    A beef cow was examined to find the cause of decreasing appetite of 2 weeks' duration. The cow was obese (body condition score, 8 of 9), and multiple fetuses were identified on palpation per rectum. Urinalysis revealed > 160 mg of ketones/dl. Abnormal serum biochemical data included high concentrations of bilirubin, creatinine, sodium, and chloride; low concentrations of total CO2 and calcium; and high activity of aspartate transaminase. Treatment included administration of dextrose solution, i.v.; propylene glycol, PO; and insulin, i.v. and SC. The cow's appetite improved gradually over 8 days of treatment. Concentration of ketone bodies in urine decreased to trace amounts by day 4. The cow was discharged on day 10 and gave birth to twins 4 days after discharge (duration of gestation, 279 days). The clinical history of this cow differed from the history of other cattle with ketosis, but mimicked pregnancy toxemia in ewes. Multiple fetuses have not been implicated as a predisposing factor in severe prepartum ketosis of cows.
