Haematological reference intervals of sows at end gestation in ten French herds, the impact of parity on haematological parameters and the consequences on reproductive performance
Changes in haematological values occur during the reproductive cycle. In veterinary swine practice, haematological reference intervals for this period are scarce. Over past decades, there has been a remarkable increase in reproductive prolificacy, possibly making previously established haematological reference intervals for sows outdated.
The aim of this study was to provide updated haematological reference intervals for sows at endgestation, to study the influence of parity on those haematological parameters and to evaluate the impact of haemoglobin levels on production performance.
