56
Mares have a _ day estrous cycle
21
57
Gestation period of a mare
11-12 months
58
Etiology of abortions in equine
bacterial: E.coli, salmonella, Klebsiella, Actinobacillus spp. viral: EHV-1
59
Etiology of contagious equine metritis
bacterial- Tayorella equigenitalis
60
Transmission of contagious equine metritis
contaminated semen from the stallion during breeding
61
clinical signs for contagious equine metritis
vaginal discharge 14 days after breeding; infertility
62
Dystocia in the mare
second stage of labor last >20 minutes (if the amniotic fluid rushes out and there is no foal 20 minutes later)
63
Etiology of dystocia in equine
maiden mare, mare/foal size mismatch, malpresentation of the foal, twins
64
Position with normal foaling:
the front feet appear first, with the soles of the feet down, or slightly sideways, nose follows the feet
65
"red bag" premature placental separation in equine
when the placenta detaches from the uterus in this manner, the foal is no longer receiving oxygen and can die quickly
66
Tx for "red bag"
immediately cut it with scissors and try to gently pull the foal
67
Mares should pass the placenta within _-_ hours of foaling
3-6
68
Etiology of retained placenta
common after dystocia as it can rip
69
clinical signs of retained placenta
placental membranes extruding from vulva >3 hours after foaling, vaginal discharge, fever, +/- laminitis 48 hours after foaling, colic symptoms
70
Tx of retained placenta
oxytocin, banamine, systemic antibiotics, uterine lavage, gentle traction, tie placenta in a knot to prevent ascending infection and tripping of the mare

forage can be taken to county extension office for submission to dx lab
81

86
Clinical signs of penile paralysis in equine
penis drops and does not retract, portion of penis distal to sheath becomes edematous and swollen
87
Why is it necessary for newborn foals to obtain antibodies through the mother's milk shortly after birth
unlike humans, there is no natural transfer of antibodies through the mothers placenta
88
Foals that do not receive these antibodies are at high risk and are dx as having a condition called
failure of passive transfer (FPT)
89
Dx of FPT
checking serum IgG in the foal within 24 hours after birth and during the first few weeks after birth
90
What is neonatal isoerythrolysis
an incompatibility between the foals and mares blood type
91
There are _ blood types in the horse
16
92
Clinical signs of neonatal isoerythrolysis
foals appear normal at birth and within the first 6-72 hours they may develop: weak/lethargic, decreased suckle, increased heart rate, increased respiratory rate and effort, white or yellow MM
93
Tx of neonatal isoerythrolysis
corticosteroids, NSAIDs, antibiotics, IV fluids, oxygen, whole blood transfusions
94
What is severe combined immunodeficiency syndrome (SCID)
a fatal condition of both B(humoral) and T(cellular) cell dysfunction
95
Tx for SCID
none, fatal
96
clinical signs of SCID
susceptibility to viral, bacterial, fungal, and protozoal organisms. Foals are normal at birth but soon develop fatal infections, particularly when circulating colostrum-derived antibody concentrations become low
97
What is dummy foal syndrome
not a disease but a broad term that applies to foals that exhibit abnormal often vague behaviors and or neurologic signs during their first few days of life
98
