Abstract
Hematologic and biochemical data are useful for indicating disease diagnosis and growth performance in swine. However, the assessment of these parameters in healthy commercial pigs is rare in China. Thus, blood samples were collected from 107 nursery pigs and 87 sows and were analyzed for 25 hematologic and 14 biochemical variables. After the rejection of the outliers and the detection of the data distribution, the correlations between the blood parameters were analyzed and the hematologic/biochemical RIs were preliminarily established using the 95% percentile RI. Correlation analysis showed that albumin was the hub parameter among the blood parameters investigated, and genes overlapping with key correlated variables were discovered. Most of the hematologic and biochemical parameters were significantly different between nursery pigs and sows. The 95% RIs of white blood cells and red blood cells were 7.18-24.52 × 10(9)/L and 5.62-7.84 × 10(12)/L, respectively, for nursery pigs, but 9.34-23.84 × 10(9)/L and 4.98-8.29 × 10(12)/L for sows. The 95% RIs of total protein and albumin were 43.16-61.23 g/dL and 19.35-37.86 g/dL, respectively, for nursery pigs, but 64.96-88.68 g/dL and 31.91-43.28 g/dL for sows. In conclusion, our study highlights the variability in blood parameters between nursery pigs and sows and provides fundamental data for the health monitoring of commercial pigs in China.
