I don't think it's right...
A
successful transition from the intrauterine to the extrauterine environment is
the first challenge for the neonatal foal.
This may be complicated by events both before and during
parturition. Once exposed to the
external environment, the neonate must rapidly develop normal behavior so as to
associate with the mare; hit its targets for righting, standing and suckling;
and develop defenses against a myriad of infectious challenges. No small task for something a few hours
old. Puts us humans to shame really.
Things
go perfectly most of the time. When they
don’t, there’s people like me. Signs of
a problem may be subtle, but knowing what to look for helps. Common presenting signs for the compromised
neonate include depression, weakness, lack of suckle reflex, fever, sepsis, and
neurological dysfunction.
Prediction of the High Risk Neonate: the
checklist
Maternal Conditions:
- Systemic problems: for example fever,
gastrointestinal compromise with potential for endotoxemia, and surgical
manipulation all affect the health of the mare, and therefore the foal.
- Reproductive problems: history of previous neonatal
compromise, placental pathology and pre partum loss of colostrum. Some mares just keep having
problems. Don’t expect her luck to
change without doing something about it.
Parturient Events:
- Abnormal gestation length. You need to know the last breeding date
(not when you were told she is going to foal) and what is normal for your
mare.
- Abnormalities of the birth canal, prolonged labor,
dystocia, premature placental separation, and premature rupture of the
umbilical cord. Some of these you
can predict, some you can’t.
- Meconium in the amniotic fluid or amnion may be the
only indication of aspiration. If
the fluids look abnormal, assume the foal has been challenged.
Neonatal Conditions:
- Growth retardation, meconium staining, or placental
disease. Not every foal looks like
it will have a trouble-free start in life – look for the signs.
- Trauma during delivery may have effects that are not
apparent until a few days of age.
Abnormal behavior and the inability to stand (30-60 minutes) and
suckle (up to 2 hours) lead to a lack of colostrum intake, preventing
adequate transfer of passive immunity and increased chances infection will
develop. Be proactive.
Once
you have an idea what may have gone on, you can start running through a list of
things which might happen next. Foals
are fairly resilient, but you have to be quick and only let them bounce once if
they fall. I’ll start going through some
of the main problems at a later time.
