Equine Breeding Mgmt. - FUNK

Question 1

Things to evaluate during physical excam for breeding soundness (4)

Answer 1

1. Conformation of feet - can her feet physically support the weight of a pregnancy?
2. BCS - negative energy balance? overweight?
3. Vulvar conformation (angle of vulve + amt that is below tuber ischii) - if malconformed, -> contamination of uterus (air, feces), infection (endometritis, placentitis), uterine scarring (fibrosis, decr. pregnancy rates)
4. Rectal palpation - location, sice & tone of: uterus, ovaries, servix; size of pelvic canal

want vulva as upright as possible; want high tuber iscii

Question 2

uterine/cervical tone during diestrus versus estrus

Answer 2

Diestrus: firm

Estrus: uterine = moderate, cervix = relaxed (need it “cushioned” for sperm transport)

Question 3

During U/S exam, the more visualized uterine edema = the futher you are in what stage?

Answer 3

Estrus (more E2 = more edema)

Question 4

Purpose of speculum exam

Answer 4

visualize the cranial vagina + the cervix

Question 5

What stage of Estrus is each photo?

Answer 5

Stage of Estrus
1. cervix sitting in middle of vagina (diestrus)
2. transition (either into our out of estrus)
3. Estrus -> soft cervix relaxed on vaginal floor

Question 6

Mare in Diestrus - what to expect on palpation / ultrasound

Answer 6

CL on ovary (bright white), tone uterus & cervix

Question 7

Mare in Estrus - what to expect on palpation / ultrasound

Answer 7

growing -> dominant follicle, milkd -> increased uterine edema, soft/relaxed cervix that starts to fall to vaginal floor

Question 8

Uterine and cervical tone scale

Answer 8

1 = firm
2 = moderate
3 = soft

Question 9

uterine edema scale

Answer 9

1 = slight
2 = moderate
3 = marked
4 = excess
