Description
| - Five years ago in Czech Republic we introduced routine blood biochemistry analyses on day 1, 10 and 30 post partum (p.p.) in 15% of cows of the herd, performed as part of transition period management. In order to make blood chemistry examinations simpler and more efficient, a new approach was tested based on the estimation of NEFA and BHB values for the day 10 p.p. according to blood chemistry results on day 1, using special regression models. In 2007-2009, 823 dairy cows (parity 1 to 7) were examined in total. They were in 19 Holstein or Fleckvieh herds, in loose housing, fed TMR without anionic salts. Paired blood samples were taken from vena/arteria coccygea on day 1 (1) and days 9-12 (2) p.p. Serum levels of Ca, inorg. P, Mg, total bilirubin, NEFA, BHB and activity of aspartate aminotransferase were analysed. The data from pluriparous cows were used by step-wise regression for prediction of NEFA2 and BHB2. Models based on various combinations of blood chemistry parameters under study were made. The model was chosen that showed the highest determination index 0.330 for NEFA2 and 0.324 for BHB2. In this model, NEFA2 and BHB2 were modeled using only NEFA, BHB, total bilirubin and Ca on day 1 (from 397 pluriparous cows) as variables. In order to prove the reliability of predicted values of NEFA2 and BHB2, data received in 2010 from 43 pluriparous cows from the same herds as previously were used. Both predicted and real values where allocated in 4 metabolic and health categories and compared. Only in 53.5% of the cows both the predicted value and the real one were within the same category. In brief assessment of cow's status (good or not) on day 10 after the delivery 83.7% cases were predicted well. So it is possible to estimate NEFA and BHB values in pluriparous cows to a certain extent. It enables to predict partially the risk of development of hyperlipomobilisation and ketosis in groups of animals within the first 10 days p.p.
