PREGNANCYAverage gestation: 330

Days about 11 monthsGestation: The length of

pregnancy from conception to parturition

PREGNANCY CONT.Pregnancy may not be

visible during the first few months

Tests should be run to make sure

• tests include: urine and blood analysis

PREGNANCY CONT.

If you have a skilled vet or breeder palpating and ultrasound are also good ways to check.

However, these options can be more expensive and the person running the test must be good at their job.

Teasing a mare is another option but it is not as accurate

PARTURITIONIs the process of giving

birth. In horses this is a generally

quick process.• Less than 30 minutes

once the water breaks

PARTURITION STAGESParturition happens in three

stages:Stage 1: Labor beginsStage 2: Foal is bornStage 3: Placenta is expelled (passed)

POSITIONFoal should exit in a diving position• Front feet then head and

shoulders.Foals start to breath as soon as the umbilical cord breaks

Dystocia – Difficult birth

AFTERWARDSFoal: foals usually stand

within 30 minutes of being born and is nursing within 2 hours.

Mare: The mare will pass the placenta and begin taking care of the foal quickly after the foal is born.
