How does oestrus behaviour compare between high yielding dairy cows and other (Bos taurus) cows?
* High yielding dairy cows exhibit longer oestrus periods and standing times
* High yielding dairy cows exhibit shorter oestrus periods and standing times
* All cows exhibit the same oestrus periods and standing times
* High yielding dairy cows exhibit longer oestrus periods bur shorter standing times

What structure is fundamental to pharmacological manipulations of the bovine oestrus cycle?
* The dominant follicle
* The hypothalamus
* The corpus luteum
* The pituitary gland

On a routine fertility visit you examine a non-cycling cow that is 80DIM and you diagnose a pyometra. What treatment do you recommend?
* A 7 day course of Amoxicillin clavulanate and recheck next week
* Start the OvSynch protocol and serve in 10 days as usual
* Treat with prostaglandin and recheck next week
* No treatment today and reassess next week
Treat with prostaglandin and recheck next week
Whilst you are on farm to do a TB test, the farmer asks you to examine a cow that has not been seen cycling since she calved 5 months ago. You scan the cow and identify a thin walled, anechoic structure on the right ovary that is 4cm in diameter. The left ovary only has small (<5mm diameter) follicles present. What treatment is inappropriate for this condition?
* OvSynch protocol
* Gonadotrophin
* CIDRSynch protocol
* Prostaglandin
Prostaglandin
What is the most common cause of anoestrus in beef suckler cows?
* The presence of a suckling calf
* Poor nutrition
* Demands of milk production after calving
* Negative effects of assisted calving on resumption of ovarian function
The presence of a suckling calf
You are asked to investigate a problem of high barren rates in a sheep flock. Which of the following pathogens is a potential infectious cause of this problem?
* Tritrichomonas foetus
* Schmallenberg virus
* Border disease virus
* Pasteurella multocida
Border disease virus
Which cause of abortion in sheep is characterised by a placentitis developing around 90 days of gestation and resulting in abortion during the last 3 weeks of pregnancy?
* Toxoplasmosis
* Enzootic abortion (C.abortus)
* Campylobacter
* Salmonella
Enzootic abortion (C.abortus)
Abortions in cattle are more commonly caused by infectious causes than non-infectious causes. True or false?
* True
* False
False
For which cause of abortion in sheep is isolation of the ewe NOT a necessity?
* Toxoplasmosis
* Enzootic abortion (C.abortus)
* Campylobacter
* Salmonella
Toxoplasmosis
When passing a trans-cervical catheter in a cow, the preferred technique is
* To pass it blind, the anatomy will guide it to the right place
* To insert a hand vaginally and guide the catheter into position
* To insert a hand rectally and guide the catheter, holding the bladder out of the way
* To insert a hand rectally to manipulate the cervix over the catheter, taking care to avoid the peri-cervical pockets

A tup at appropriate BCS for breeding will measure
* 1 - 1.5
* 4.5 - 5
* It doesn’t matter
* 2.5 - 3.5
2.5 - 3.5
A post-legged bull is good because it means his hocks are nice and strong for mounting cows.
* True
* False
False
How will pyrexia affect fertility in the male?
* For the better, the higher temperatures mean the sperm are more active
* For the worse, the testes need to operate at a temperature below body temperature and sperm will be killed off
* There will be no effect
For the worse, the testes need to operate at a temperature below body temperature and sperm will be killed off
When collecting a semen sample from a bull, using an Artificial Vagina is the safest method for the operator
* True
* False
False
On a semen sample, progressive motility should be assessed at which magnification?

* X10
* X200
* X10,000
