Why isn't this mare pregnant?
no concerning history
inspect season/lighting
decreasing/inadequate light, consider...
out of season breeding complication, need to increase light exposure
increasing/adequate light
perform physical exam
high BCS
:red_circle: blood test for PMSG
abnormal
metabolic syndrome
EPPID
normal
low BCS
oral exam to assess for dental disease
dental disease leading to poor nutrition
normal
ration assessment
adequate
energy not adequate to support lactation, new pregnancy, and self
fecal egg count
normal
severely high
energy being parasitized, cannot support lactation, new pregnancy, and self
all normal/WNL
lameness exam
normal
chronic pain/lameness
perineal conformation assessment
normal
abnormal, suspect ascending infection
vaginoscopy
ultrasound
suspect metritis, endometritis, pyometra
uterine culture and cytology
inspect her shelter
terrifying or stressful
chronic stress induced infertility
normal
signalment
currently nursing :baby_bottle:

at a local farm
open at 15 day preg check :angry:
3rd time this has occurred

DAMNIT scheme
Toxic/Traumatic
stressful environment/chronic stress
temperature fluctuations
extreme temperatures
poor lighting
unsafe
Traumatic last birth
cervical fibrosis
vaginal tear
rectal tear
cervical tear
chronic pain
Inflammatory/Infectious :biohazard_sign:
excessive uterine edema
local infection
metritis
Pyometra
endometritis
systemic infection
bacterial
Contagious Equine Metritis
massive parasite load
Nutritional/Neoplastic
Ovarian tumor/cyst(s)
Uterine tumor/cyst(s)
low BCS
dental disease
major vitamin/mineral deficiencies
low ration
high BCS
Metabolic :knife_fork_plate:
wrong season
Hormone imbalances
PPID
EED
Metabolic disorder
long cycling
Autoimmune/Allergic
Degenerative/Developmental
embryonic loss
aged gametes
poor perineal conformation
manner of breeding
pasture-bred
handbred
timing of breeding relative to ovulation
too soon or too late, she will not be pregnant
bred at appropriate time
frequency of teasing, time to return to heat after breeding
short cycling? suspect endometritis
uterine culture and cytology
long cycling? suspect non-infectious EED
first time mating this dam and sire?
genetic testing for compatibility
uterine biopsy
normal
fibrosis
bred concurrently with other mares on farm?
if other mares were bred
check for concurrent pregnancy issues
if yes, consider
infectious case
stallion not sound
if no, put infectious or stallion issues lower on ddx
other mares not bred
dystocia history
rectal palpation
abnormal, ultrasound
uterine abnormality
uterine cysts
cytology
uterine culture
if nothing found, suspect fibrosis
uterine biopsy
intraluminal free fluid and/or excessive edema
uterine culture and cytology
endometritis
ovarian abnormality
repeated hemorrhagic anovulatory follicles
blood assay for PMSG
if positive, then retained endometrial cups
ovarian cysts
ovarian mass
normal
vaginoscopy
discharge
suspect endometritis
uterine culture and cytology
normal
digital exam of cervix
foaling injury - cervical lacerations
urine pooling
foaling injury - urethral damage
cervical adhesions
foaling injury - damage to cervix
