In
this study, the effect of serum β-hydroxybutyric acid and calcium
concentrations, which are the parameters used in the diagnosis of ketosis and
hypocalcemia in lactation period, on left displaced abomasum (LDA) has been
investigated. The lactation period covering the 3 weeks before and after
parturition, known as the transition period, is highly important for high yield
dairy cows (Holstein Friesian cattle). Hormonal and metabolic changes occur in
this period. The energy requirement, which increases in direct proportion with
the milk yield at the beginning of lactation, cannot be met with insufficient
dry matter consumption, however, it is compensated with the mobilization of
body fat. Ketosis and fatty liver are nutritional diseases that are observed in
animals with high milk yield resulting from the disturbances in energy
metabolism. Hypocalcemia and ketosis are the most important risk factors in the
development of left displaced abomasum (LDA) in high-yield milk cows.
Hypocalcemia and ketosis are also the most important nutritional diseases in
the transition period. In this study, 17 Holstein Friesian cattle were used in
group 1 that were diagnosed with left displaced abomasum after hearing the
‘‘ping’’ sound, and 17 healthy, randomly selected Holstein Friesian cattle were
used in group 2. Blood analyses (BHBA and Ca) were performed in group 1 and 2
after parturition.
