A retrospective study was conducted to determine the relationship between serum non-esterified fatty acids (NEFA), ?-hydroxybutyrate (BHBA), glucose and calcium (Ca) with the occurrence of displaced abomasum (DA), clinical ketosis and culling in Holstein cows. Eight hundred and forty-nine cows from 16 farms were sampled weekly for the first 3 weeks post-partum. The cows were under clinical observation from calving until 60 days in milk (DIM) and during this time there were 22 cases of DA, 31 cases of clinical ketosis and 39 cows were culled. Elevated concentrations of BHBA were associated with DA, clinical ketosis and culling. In the first week after calving, cows with serum BHBA ?1000?mol/L had 13.6 times greater odds of developing DA than cows with lower values. Serum NEFA and BHBA concentrations during week 1 were associated with the subsequent occurrence of clinical ketosis. The odds of clinical ketosis were 6.3 times greater in cows with serum NEFA ? 1.0mmol/L in the first week after calving. In addition, cows with BHB ?1200?mol/L in the first week after calving, were at 4.7 times greater risk of developing clinical ketosis. In the first and second weeks after calving the serum Ca concentration was associated with subsequent culling. In addition, cows with NEFA concentration ? 1.0mmol/L were 3.6 times more likely to be culled within the following 2 months. The study indicated that early post-partum serum BHBA, NEFA and Ca concentrations have potential as indicators of disease and culling risk in dairy cows.
