Answer :
Examining mammary secretions in mares before parturition serves the purpose of:
1. Checking for infections or abnormalities in the colostrum: By examining mammary secretions, veterinarians can detect any signs of infection or abnormalities in the colostrum, which is crucial for the health of the newborn foal. Infections or abnormalities in the colostrum can negatively impact the foal's immune system and overall health.
2. Confirming that the mare is healthy and ready for parturition: The examination of mammary secretions can help confirm the mare's health status before parturition. Ensuring that the mare is healthy and ready for parturition is essential for a successful delivery and the well-being of both the mare and the foal.
In summary, examining mammary secretions in mares before parturition is important for checking the colostrum for infections or abnormalities and confirming the mare's health status prior to giving birth.
