Foal Sepsis & Failure of Passive Transfer (FPT)

Image for the Reproduction & Breeding category

Foals are born without their own antibodies and depend on taking up immune substances (IgG) from the first colostrum. If too little colostrum is taken up in the first hours of life (failure of passive transfer), immune protection is lacking — the main risk factor for a life-threatening blood poisoning (sepsis) of the newborn.

Veterinary care required

This condition belongs in veterinary diagnosis and treatment. Compounds are at most supportive.

Priority · vet & management

Emergency of the newborn phase. The window for colostrum uptake is very short — the gut barrier closes within about the first 12 to 24 hours of life. The vet checks the antibody status (IgG test) in the first 12-24 hours and arranges care (colostrum/plasma, intensive treatment) in case of FPT or suspected sepsis.

Possible causes

  • · too-late or too-low colostrum intake (FPT)
  • · poor-quality colostrum / premature milk flow of the mare
  • · weak or sick foals (e.g. after dystocia)
  • · placentitis / prenatal infection
  • · germ entry via the navel

Supportive compounds · supplementary feed, not medication

Prevention

Early, sufficient first drinking of colostrum, hygiene and navel care as well as a veterinary IgG check in the first hours of life are the decisive precautionary measures.

Equiterna's take

Equiterna emphasises the very short time window of colostrum intake — the initial care (colostrum, IgG test, plasma if needed) is veterinary and time-critical; compounds replace neither colostrum nor veterinary care.
