Assessment of Hematologic and Biochemical Parameters for Healthy Commercial Pigs in China

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 × 109/L and 5.62–7.84 × 1012/L, respectively, for nursery pigs, but 9.34–23.84 × 109/L and 4.98–8.29 × 1012/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.

Aging and Changes in White Blood Cells Count and Immunity: A Systematic Review

“…These observational studies have examined wide age categories, primarily middle-aged individuals, as homogenous groups without the ability to differentiate prognoses for other age classes, such as the current study's 75-year-old participants. [21,[29][30][31][32] In line with other studies, a study revealed that total and differential WBCs underwent significant alterations during childhood, particularly in the early years. Additionally, as compared to EO#, BASO#, and MONO#, LYMPH# and NEUT# showed more clear age-dependent alterations throughout childhood.…”

siRNA-mediated reduction of a circulating protein in swine using lipid nanoparticles

“…Thromboxane B2 levels, a known marker of CARPA, were comparable to baseline levels in siPLG- and PBS-treated swine at 5 h ( Figure 3 A). To monitor for potential signs of inflammation, white blood cell (WBC) count was analyzed, and levels were within a normal range 34 and comparable to untreated swine ( Figure 3 B). Untreated swine underwent anesthesia but did not receive any further injections; this control group was included in specific analyses when blood samples in the PBS group were not available.…”

Biochemical serum characteristics in fattening pigs infected with porcine circovirus type 2

“…PCV2 affects the functioning of organs and systems, leading to morphological and biochemical changes in the blood composition (Rajesh et al, 2020). Meanwhile, the biochemical profile of animals in the industrial herd is utilized to monitor the health status of widely used animals, assessing pig herds for the presence of diseases, predicting their productivity, or evaluating feeding practices (Yefimov et al, 2017;Zhang et al, 2022;Dimitrakakis et al, 2022). However, the assessment of these parameters in healthy industrial pigs is seldom encountered.…”
