E. Only the primary follicles can be examined rectally
C. Ultrasonography only allows the terciar (antral) follicles to be examined
Which statement is true in connection with the follicles in mares?
A. All tercier (antral) follicles can produce significant quantities of estrogens
B. The minimal size of tercier (antral) follicles is = 30-40 mm in diameter
C. The secondary follicles can produce significant quantity of estrogens
D. After the beginning of the atretic degeneration the follicles can not be detected by ultrasonography
E. At the beginning of the atretic degeneration the size of a follicle still may be 30-40 mm in diameter
E. At the beginning of the atretic degeneration the size of a follicle still may be 30-40 mm in diameter
Choose the right answer:
* Maternal recognition of the pregnancy is mediated by interferon tau produced by the conceptus
* Maternal recognition of the pregnancy is mediated by estradiol 17 beta produced by the conceptus between day 12-15
* Maternal recognition of the pregnancy is mediated by a 40.000 D molecular weight protein which is not interferon tau and produced by the conceptus
* The pregnancy in the mare is recognized after the decapsulation by day 22
* The pregnancy in the mare is recognized after the implantation by day 50
Maternal recognition of the pregnancy is mediated by a 40.000 D molecular weight protein which is not interferon tau and produced by the conceptus
When is the capsule development in mare?
From day 6 to day 22-26
What is Deslorelin used for in mares?
To delay estrous (in case of transporting, competition, etc.)

What is the marginal haematoma?
Haematoma at the edge of placenta zonaria in carnivores
How can you mechanically stimulate respiration in the new-borns?
Mouth to mouth expired air, tracheal tube with AMBU balloon
Why is there a lot of keratinized cells in cytology of dog during oestrus, and which hormone is responsible for this?
To decrease irritation to the vagina during copulation and the hormone is estrogen
