Serum haptoglobin and C-reactive protein concentration in relation to rectal and vaginal temperature of early postpartum sows

摘要

Various attempts were made to improve the diagnosis of the periparturient hypogalactia syndrome in sows. A new approach was the detection of elevated concentrations of acute phase proteins. The objective of our study was to investigate the serum concentrations of haptoglobin (Hp) and C-reactive protein (CRP) in sows on Day 7 postpartum and relationship to body temperature. From Day 1 to Day 6 postpartum, 199 sows were clinically examined and a blood sample was taken for measuring Hp and CRP at Day 7. The median of Hp and CRP were 1.83 mg/mL (interquartile range: 1.42-2.13 mg/mL) and 60.0 g/mL (interquartile range: 15.2-216.5 g/mL). We did not find a correlation between Hp and CRP (p = 0.11, P = 0.12) nor a difference between sows categorized as ill and healthy sows in Hp concentration (P = 0.1) and CRP (P = 034). Sows with Hp > 2.13 mg/mL had a higher rectal temperature than sows with Hp 2.13 mg/mL (P = 0.037), but there was no difference in vaginal temperature (P = 0.24). Regarding CRP, sows with CRP greater than 216.5 gg/mL had higher rectal temperature (P = 0.017) and vaginal temperature (P = 0.02) than sows with CRP 216.5 gglmL. As demonstrated in this study, Hp and CRP do not support the detection of early postpartum disorders in sows. (C) 2016 Elsevier Inc. All rights reserved.
