1-6ml
what is indicated by the less opaque of the collected semen
low conc of t he sperm
the high magnification is used to evalutate the
individual movement of the spermatozoa
what is the response of the live spermatozoa in the hypo-osmotic swelling test
swelling ofthe tail
what is the peroxidase test used for
to detect WBC
which spermatozoa is stained in the viabilitity test (eosin)
dead
what does normozooprermia mean
all the spermatozoa are normal?
working princible of fluroescent in situ hybridisation (FISH)
coincubation of denatured dna sample with fluorescin labelled dna probe
methods for evaluation of recovered embryos for freezing of fresh transfer
incorect ans
visualisation of the female pronucleus by staining
what do endometrial cups produce
PMSG
the follicular phase consists of
proestrus and oestrus
where can the GnRH surge centre be found in males
males dont have one
how could you explain the decrease in body temp prior to partuition in dogs
Decrease in progesterone
what kind of change happen during slow cooling of native cells
due to water efflux the cell volume decrease are the intracellular osmotic pressure increase
what does the analytical sensitivity show
minimal detectable conc
what influences the changes in vaginal epithelium during heat
oestrogen
mark the incorrect statement regarding clinical and biochemical alterations in pregnant bitch
constantly decrease energy requirements
which is not a sign for impending partuition in bitch
incorect statement
sudden increase in body temp by 1-2oC
how long is a dogs pregnancy
62-63 days
what is the meaning of preovulatory luteinization
the plasma progesterone level starts to increase prior to LH peak
mark the incorrect statement. which factor does not predispose to primary uterine inertia
high humidity
which method can we not use for AI if we use frozen semens
intravaginal
has to be transuterus
what progesterone level is expected at day 0 of the oestrus cycle (LH peak) in the dog
rises above 2ng/ml
what do you not necessarily have to think about systocia
the bitch has been panting, trembling, restless for 6hrs but nothing else
which statement is false concerning the hormonal background of the luteal phase in bitches
The continuationof pregnancy is maintained by progesterone produced by the corpus luteum and the placenta produced in dogs produce p4
how does the plasma progesterone change after ovulation
increases
which factor does not influence the success of AI
the weatehr of the day
mark the incorrect statement regarding clinical pseudopregnancy
the use of dopamine antagonist as primary medication is recommended
clinical signs of proestrus in dogs are induced by
increase of oestrogen
which is a misjudgement of foetal heart rate
100-150BOM means moderate foetal distress
what happens are the end of canine pregnancy
the relaxine conc is high
what does capacitation mean
the spermatozoa acquire teh hyperactive motility
what does the acrosome reaction mean
fusion of outer acrosomal membrane with plasma membrane of spermatozoa
what is the something acrosome
formation of the zone block
what does polspermiosis mean
more than one spermatozoa penetrating the oocyte
what is the location of the fusion proteins on the spermatozoa
the equatorial segment which can be found on the head of spermatozoa
what is the task of fusion proteins
to secure the physical connection between the head of the spermatozoa and the oolemma
at which stage of embryo developement the differentiation of the cell blastomeres is started
blastocyst stage
in the dog - maternal recognition is based on the production of
no significant maternal recognition
in the eoman the maternal recognition odd pregnancy is based on teh production of
human chorionic gonadotropin
what develops into corpus luteum afterovulation
the theca and granulosa cells of the follicle convert into luteal cells
what is the reproductive role of kisspeptin neurons
based on melatonin input, stimulates or inhibits the GNRH production
what is the 2 cell 2 gonadotropin model
testosterone production of theca cells (LH) and its conversion to oestrogen by granulosa cells (FSH)
what is regulating seasonality
pineal gland melatonin through kisspepin GNRH axis
difference btween protein and steroid hormones mechanism of action
protein hormones –> cytoplasm
steroid hormones –>cytoplasm and nucleus
how can the optimal time of breeding (insemination) of the dog be predicted
a combined investigation of behaviour bloody discharge vaginal cytology and P4 assay
