| Popis: | The prevalence of bovine ketonemia among 1155 dairy cows in various stages of lactation and parity on 25 Jordanian dairy herds was studied. The cross-sectional study was conducted during the spring of 1992. Serum concentration of beta-hydroxybutyrate (BHB)0.9 mmol/l, between 0.9 and 1.7 mmol/l, and1.7 mmol/l were considered to indicate normal, mild and severe ketonemia, respectively. The point prevalences of mild and severe ketonemia were 22% and 3.8%, respectively. The prevalence of ketonemia decreased with increasing herd size. Associations between the prevalence of ketonemia and parity, stage of lactation, metritis, somatic-cell count (SCC) and serum cholesterol levels were not significant (p0.05). |
