[Progesterone in mare's milk: suitable for early pregnancy detection?]
Tijdschrift Voor Diergeneeskunde
|May 15, 1985
Summary
Early pregnancy diagnosis in mares is possible by measuring milk progesterone levels. Pregnant mares showed significantly higher progesterone concentrations (6.7-30.0 ng/ml) compared to non-pregnant mares (0.0-4.2 ng/ml) using ELISA.
Area of Science:
- Veterinary Science
- Reproductive Biology
- Endocrinology
Context:
- Early pregnancy detection in mares is crucial for reproductive management.
- Traditional pregnancy diagnostics can be invasive or time-consuming.
- Milk progesterone analysis offers a non-invasive alternative for early assessment.
Purpose:
- To establish an early diagnostic method for pregnancy in mares.
- To determine progesterone concentrations in mare's milk during early gestation (15-19 days).
- To differentiate between pregnant and non-pregnant mares based on milk progesterone levels.
Summary:
- Milk progesterone concentrations were measured in 21 mares between days 15-19 of gestation.
- Enzyme-linked immunosorbent assay (ELISA) was used for progesterone determination.
- Pregnant mares (n=12) exhibited significantly higher milk progesterone levels (6.7-30.0 ng/ml) than non-pregnant mares (n=9, 0.0-4.2 ng/ml).
Impact:
- Provides a reliable, non-invasive method for early pregnancy diagnosis in mares.
- Facilitates timely reproductive management decisions in equine breeding programs.
- Demonstrates the utility of milk progesterone analysis as a diagnostic tool in veterinary medicine.
