3Choose the correct statement regarding pregnancy diagnosis in the mare.
- Aa. Palpation per rectum can be performed by a skilled clinician for pregnancy diagnosis 16 days after ovulation
- Bb. Trans-rectal ultrasound can visualize a conceptus at 16 days post-ovulation.
- Cc. If you palpate a mare per rectum 14 days after the end of an oestrus in which breeding occurred and there is tone in the uterus, tone in the cervix (vaginal speculum examination also shows a high, white, tight cervix); you can confidently tell the mare is pregnant.
- Dd. A positive test for eCG, even though no conceptus can be seen by trans-rectal ultrasound most likely means the eCG test was a false positive and the mare was never pregnant.
- Ee. Oestrone sulphate is a good test to use to determine foetal viability at 35 days post ovulation.

5You examine a mare at 15 days post ovulation by transrectal ultrasound. You noted 16 days earlier that the mare ovulated two follicles and the uterus had no observable cysts at that time. What is the best course of action for you to take?
- Aa) Separate the two vesicles and aspirate one trans-vaginally.
- Bb) Separate the two vesicles and crush one by manually compressing it.
- Cc) Do nothing at this time as chances are one will reduce spontaneously.

12The owner of a 6-year-old, maiden Arab mare has had several attempts to breed her horse naturally to a stallion during the month of September. The mare acts erratically, showing signs of heat on some days, while acting aggressively towards the stallion on others. She managed to have the mare bred once 7 days ago, but now rings for advice as the mare appears to be showing interest in the stallion again.

16You have to artificially inseminate a mare with a single dose of frozen semen. You examine the mare late on a Friday afternoon and note that she has a single 35 mm follicle on one ovary and is in oestrus. The problem is that you have an important golf tournament that you need to attend this weekend and will be unable to monitor the mare as intensively as you may want to. You inject her with human chorionic gonadotrophin. From the following options select the one best insemination regime to maximise the probability of conception occurring
- AInseminate the mare immediately on Friday afternoon.
- BInseminate the mare 24 hours later.
- CInseminate the mare 48 hours later.
- DUltrasound the mare Saturday afternoon, if ovulation does not appear imminent AI 8 to 12 h later, if ovulation had occurred or looks imminent AI the mare.
- EUltrasound the mare Sunday afternoon, if ovulation does not appear imminent AI 8 to 12 h later, if ovulation had occurred or looks imminent AI the mare.
17You diagnose pregnancy in five Thoroughbred mares between 30 and 38 days after natural service. You are considering if there is any need to perform a Caslick’s operation on any of the mares. The conformation of the vulva of each mare is described. Which mare would NOT require a Caslick’s operation?
- AA. Mare A: The vulva slopes 15° from the vertical, with 50% of the vulva length located ventral to the floor of the pelvis, no air is heard entering the vagina on parting the lips of the vulva.
- BB. Mare B: The vulva slopes 20° from the vertical, with 70% of the vulva length located ventral to the floor of the pelvis, no air is heard entering the vagina on parting the vulva lips.
- CC. Mare C: The vulva slopes 40° from the vertical, with 30% of the vulva length located ventral to the floor of the pelvis, no air is heard entering the vagina on parting the lips of the vulva.
- DD. Mare D: The vulva slopes 10° from the vertical, with 75% of the vulva length located ventral to the floor of the pelvis, no air is heard entering the vagina on parting the lips of the vulva.
- EE. Mare E: The vulva slopes less than 5° slope from the vertical, with 85% of the vulva length located ventral to the floor of the pelvis, air is heard entering the vagina on parting the vulva lips.
