Hematological and biochemical features of postpartum fever in the heavy draft mare.
Abstract: Heavy draft mares potentially have a higher risk of suffering from postpartum fever (PF) than light breed mares. The purpose of this study was to compare hematological and biochemical features between clinically healthy mares (n=40) and PF-affected mares (n=16). Mares were classified as having PF when their rectal temperature rose to >38.5°C within 96 hr of foaling. The numbers of leukocytes, lymphocytes, and neutrophils and the serum magnesium level were significantly lower in PF-affected mares. The serum SAA and NEFA levels were significantly higher in PF-affected mares. Strong inflammation responses, fat mobilization associated with negative energy balance and possibly endotoxin participate in hematological and biochemical features of PF in heavy draft mares.

The research sought to compare the different blood and chemical traits in healthy mares and those affected by a post-birth fever, particularly in heavy draft mares who may be at higher risk of this condition.
Objectives of the Study
- The study aimed at comparing hematological (related to blood) and biochemical profiles between healthy and postpartum fever (PF) affected heavy draft mares.
- The researchers looked into the rectal temperatures of mares within 96 hours of giving birth to establish whether they had PF.
Methodology and Participants
- The study involved 56 mares, with 40 of them being clinically healthy and 16 diagnosed with PF.
- Mares with rectal temperatures exceeding 38.5°C within 96 hours of foaling were classified as having PF.
Key Findings
- Prominent blood elements like leukocytes, lymphocytes, and neutrophils were noted to be markedly lower in PF-affected mares than in the healthy ones.
- The serum levels of magnesium were also notably lower in PF-affected mares than their healthy counterparts.
- On the other hand, the PF-affected mares revealed significantly higher levels of Serum Amyloid A (SAA) and Non-Esterified Fatty Acids (NEFA), which are essential indicators of inflammation and lipid metabolism respectively.
Implications of the Findings
- The research correlates PF in heavy draft mares to strong inflammatory responses, negative energy balance leading to the mobilization of fat, and possibly the involvement of endotoxin.
- This suggests that monitoring these hematological and biochemical changes can be crucial in identifying PF in heavy draft mares in the early stages and instituting effective treatment strategies.
