Abstract:
In high yielding dairy cows, one of the major cause of lameness during transition period is the altered nutritional status of pregnant animal. Concentrations of essential nutrients get varied and often decrease around calving due to physiological factors and thus extra-supplementation is recommended in these animals. Blood measures are frequently used in assessment of the vital nutrients for predicting the risk of lameness during this period. The objective of this study was to investigate the nutritional status of healthy and lame Karan Fries (KF) cows and their association with lameness score during transition period. For this fifteen high-yielding crossbreed (KF) healthy cows and fifteen high yielding crossbreed (KF) lame cows were randomly selected from the Livestock Research Centre (LRC) of National Diary Research Institute, Karnal for pooled blood sample collection. Samples were collected 60d, 15d pre-partum, on the day of calving, and 60d, 15d post-partum. The results revealed that the mean plasma biotin, zinc (below critical level) and calcium (within range) levels were significantly lower (P<0.05) in lame KF cows while β-hydroxybutyrate (BHBA) concentrations was significantly higher, however no significant difference in plasma copper, glucose and non-esterified fatty acids (NEFA) concentrations was found in lame cows as compared to normal KF cows during this period. There was also significant (P<0.05) variation of blood biochemical profiles (glucose, NEFA and BHBA) and plasma biotin concentration among different lameness scores (1-5) whereas no relation of mineral profiles (calcium, zinc and copper) was seen with lameness score.
