How could be evidenced the completed ovulation in the dog?
- with LH concentration measurement
- female accepts approach of males
- measurement of oestrogen concentration
- measurement of progesterone concentration
- between day 9-13 after onset of heat
- measurement of progesterone concentration
What is characteristic of the reproductive cycle in dogs?
- Seasonally polyesters

What do endometrial cups produce?
- hCG
- PMSG
- PGF2⍺
- Progesterone
- PMSG
These cups produce equine chorionic gonadotropin (eCG), also known as pregnant mare’s serum gonadotropin (PMSG)
Which statement is correct? Clinical signs of proestrus in dogs are induced by..
- increase of progesterone concentration
- increase of oestrogen concentration
- LH peak
- increase of prolactin concentration
- increase of oestrogen concentration
What is NOT characteristic of a cat’s reproductive cycle? (Mark the incorrect statement)
- it is characteristic by seasonal polyestrus
- it is characterised by induce ovulation
- spontaneous ovulation does not occur
- the cycle can be interrupted by summer heat or stress

- approx. 7 days, one day before the end of oestrus
- approx. 7 days, one day before the end of oestrus
Duration of oestrus: 5-7 days (can be as short as 2 days, and as long as 11 days)
In how many fractions does the dog ejaculate the semen?
1
2

- a pseudohermaphrodite calf
- a sterile heifer born a a co-twin of a bull
High-yielding dairy cows have…
- Too much progesterone

What does the embryo need for the maternal recognition in the mare?
- Hatching
- Intrauterine migration
- Formation of endometrial cups
- Placentation
- Intrauterine migration
What is the “back pressure test”?
- During oestrus, the sow stand still, if we apply pressure on its back
- During pregnancy, the sow stands still, if we apply pressure on its back. This is a method for early pregnancy detection.
- If we turn a newborn piglet on its back, it will turn to sternal position quickly. We can judge their vitality with this method.
- If we apply pressure on the back of a healthy pig while it’s laying down, it will stand up. This way, we can select the sick ones.
- During oestrus, the sow stand still, if we apply pressure on its back
Maternal recognition of pregnancy in cow is driven by…
- Embryonic mobility phase
- Estrogens
- B-INF-tau
- Caprine-INF-tau
- B-INF-tau

During a normal oestrus in the mare, we see..
- there are no behavioural oestrus signs
- uterine oedema before ovulation
- 2-3cm fluid in the uterine lumen
- more dominant follicles and active corpora luteal
