Horse Foal Rejection and Foster Mare Solutions

Mare rejection of foals is a welfare emergency requiring immediate intervention and, if unsuccessful, foster mare or artificial rearing solutions.

Key Facts

Foal rejection occurs most commonly in maiden mares who are unprepared for the foal's approach
Signs include refusing to allow nursing, kicking at the foal, or severe aggressive behavior
Some mares accept the foal with restraint and patient introduction over several hours
Foster mares that have lost a foal can be introduced to orphaned foals using foal skin scent transfer
Artificial rearing is a welfare-intensive option requiring frequent small bottle feeds every 1-2 hours
Nurse mares - mares kept for foal raising - have their own welfare considerations including separation from their own foal

Welfare Considerations

Foal rejection creates an acute welfare emergency for the newborn who needs colostrum within hours. The distress of a rejected foal and the necessary handling of an aggressive mare during intervention represent significant welfare challenges. Preparation for potential rejection in maiden mares, rapid intervention when rejection occurs, and access to foster mare networks or artificial rearing expertise are welfare necessities for breeding operations. Nurse mare welfare is an often overlooked aspect of foal rearing.

What You Can Do

Supervise maiden mare foalings closely - rejection is most common in first-time mares
Have a plan for foal rejection before foaling season including foster mare network contacts
Attempt gradual introduction with restraint before assuming rejection is permanent
Maintain colostrum banks for rejected foals who need immediate immune protection
Research artificial foal rearing requirements before breeding - it is intensive and demanding
Consider the welfare of nurse mares and their own foals when using nurse mare services
