Abstract

A study was conducted on the biochemical constituents of pure Sahiwal and Jersey × Sahiwal crossbred animals in tropical conditions. Six animals were selected from each category of Sahiwal heifers, Sahiwal cows and Jersey × Sahiwal crossbred cows. The biochemical constituents of the above animals were recorded during the experimental period of 21 days. The haematocrit values (%) of Sahiwal heifers, Sahiwal cows and Jersey × Sahiwal cows were ranged from 29.17 ± 1.22 to 68.00 ± 1.06, 31.00 ± 1.46 to 67.00 ± 1.06 and 31.17 ± 1.17 to 75.83 ± 0.59, respectively. A non-significant difference was observed in haematocrit values of Sahiwal heifers and cows, whereas a significant (P<0.01) variation was recorded for Jersey × Sahiwal crossbred cows. The serum glucose, urea and creatinine levels (mg/dL) of Sahiwal heifers, Sahiwal cows and Jersey × Sahiwal cows ranged from 61.90 ± 1.34 to 97.32 ± 0.63, 58.61 ± 1.20 to 96.90 ± 0.65 and 59.26 ± 0.58 to 113.33 ± 0.71, 11.72 ± 0.94 to 47.21 ± 0.64, 11.70 ± 0.65 to 45.44 ± 0.42 and 14.00 ± 0.58 to 63.99 ± 0.41 and 1.25 ± 0.07 to 9.81 ± 0.13, 1.29 ± 0.09 to 9.90 ± 0.17 and 1.43 ± 0.10 to 16.18 ± 0.15, respectively. The average serum glucose values were significantly (P<0.01) different among all the experimental animals during adaptability. The serum calcium and phosphorous levels (mg/dL) of Sahiwal heifers, Sahiwal cows and Jersey × Sahiwal cows ranged from 10.59 ± 0.29 to 27.17 ± 0.29, 10.84 ± 0.27 to 26.61 ± 0.46 and 10.45 ± 0.33 to 36.76 ± 0.71, 5.85 ± 0.05 to 18.91 ± 0.21, 5.94 ± 0.08 to 18.87 ± 0.12 and 5.88 ± 0.10 to 20.80 ± 0.13, respectively. A nonsignificant difference was observed in serum calcium and phosphorous levels for Sahiwal heifers and Sahiwal cows, whereas a significant (P<0.01) variation was recorded for Jersey × Sahiwal crossbred cows in relation to adaptability. The present study concludes that haematocrit, glucose, urea, creatinine, calcium, phosphorouslevels of the Sahiwal cows were significantly (P<0.01) higher during the first three days of the experimental period and later declined to the normal range of the species. In the case of Jersey × Sahiwal crossbred cows, higher levels of haematocrit and the above serum constituents were observed for a period of six days, which later declined to reach the normal range of the species in tropical environments.
