Energy and mineral metabolism of peripartum mares and foals of the Quarter Horse breed.

Abstract: Several studies have demonstrated variations in peripartum blood biochemical analytes used to monitor the health status of mares and their foals of different breeds. Objective: We aimed to characterize the physiologic changes of peripartum energy and mineral metabolism in healthy Quarter Horse mares and their neonatal foals. Methods: Blood samples were initially collected from 17 mares on days 60 and 30 prepartum, and from mares and their foals on the day of parturition (after colostrum ingestion), and on days 15, 30, and 60 postpartum. The serum concentrations of calcium, phosphorus, magnesium, total cholesterol (T-Cho), triglyceride, beta-hydroxybutyrate (BHBA), and nonesterified fatty acids (NEFA) were measured using commercial kits. Statistical differences were analyzed using one-way ANOVA followed by Tukey's test (parametric variables) or the Kruskal-Wallis test followed by Dunn's multiple comparison test (nonparametric variables). Results: Fourteen of 17 healthy Quarter Horse mares and their neonatal foals remained in the study until termination. Serum BHBA, T-Cho, and calcium concentrations in mares showed significant differences during the observation period. Serum BHBA concentrations increased from 60 days prepartum to 60 days postpartum. Postpartum serum T-Cho and calcium concentrations significantly decreased until day-30 postpartum. In the foals, NEFA, T-Cho, calcium, and magnesium concentrations significantly differed between sampling times. In the foals, serum NEFA concentrations decreased from parturition until day-60 postpartum, while serum T-Cho, calcium, and magnesium concentrations were lowest at day-30 postpartum. Conclusions: The temporal changes observed in the blood biochemical analytes of this study could be used to improve the clinical evaluation of periparturient mare and neonatal foal Quarter Horses.

This research investigates the variations in the metabolism of energy and minerals in Quarter Horse mares and their newborn foals during the peripartum period. It provides useful insights that could enhance the clinical evaluation of both the mares and their offspring.

Research Objectives and Methodology

  • The purpose of this study was to understand the physiological changes that occur in the energy and mineral metabolism of healthy Quarter Horse mares and their newborn foals throughout the peripartum period.
  • The researchers collected blood samples from 17 mares at 60 and 30 days prior to giving birth. They also collected samples from both the mares and their babies on the day of birth (after the ingestion of colostrum), as well as on days 15, 30, and 60 post-birth.
  • A variety of blood biochemical components were measured in the samples such as calcium, phosphorous, magnesium, total cholesterol (T-Cho), triglyceride, beta-hydroxybutyrate (BHBA), and non-esterified fatty acids (NEFA).
  • The team analyzed any statistical differences using a one-way ANOVA followed by Tukey’s test for parametric variables, and the Kruskal-Wallis test followed by Dunn’s multiple comparison test for nonparametric variables.

Research Findings

  • Out of the initial 17, 14 healthy Quarter Horse mares and their newborn foals remained in the study until it was completed.
  • There was a notable difference in the mares’ serum BHBA, T-Cho, and calcium concentrations over the study period. The serum BHBA amount increased from day 60 pre-birth to day 60 post-birth.
  • The post-birth serum concentrations of T-Cho and calcium decreased significantly until day-30 post-birth.
  • In the foals, the NEFA, T-Cho, calcium, and magnesium samples varied significantly between the sampling periods. The serum NEFA concentrations in the foals declined from birth until day-60 post-birth.
  • The foals’ T-Cho, calcium, and magnesium concentrations were found to be at their lowest levels at day-30 post-birth.

Conclusions

  • The significant changes observed in the blood biochemical markers through the study period can be effectively utilized to improve the clinical evaluation of Quarter Horse mares and their newborn foals during the peripartum period.
