Q

What degree of sampling for the stallion BSE?

A

2 collections and evaluations 1 hour apart.

17
Q

what is acceptable total scrotal width?

A

> 10 cm

18
Q

preparing the stallion procedure

A

tease a bit, look at penis, culture any masses or things from the urethra fossa, wash the penis, mount and collect

19
Q

preparing the AV for collection

A

non-spermicidal lube on the ring, put on collection bag, fill with water to 55C (so 44-50 when sampling), mount onto phantom and divert penis when riding

20
Q

what temperature does the AV need to be?

A

55 C (44-50 when sampling)

21
Q

routine semen evaluation includes

A

removing water –> put through the filter –> measure gel-free volume –> evaluate progressive motility on 400X –> measure % progressive (speed) –> then concentration –> cacl total motile sperm –> sperm morphology (live/dead count) on 1000X –> total PMMNs

22
Q

how do we dilute sperm with extender?

A

usually 1:1

23
Q

what ratio of stain to sperm for morphology

A

60:40 on warm, dry slide.

24
Q

What are possibilities when we see urosperia

A

HyPP

RAO

25
Q

What do we classify as below average sperm?

A

50 mil/ml,

26
Q

What do we classify as average sperm?

A

30-70% PMMNs, concentraion 50-100 mil/ml, 30-50% normal morph

27
Q

What do we classify as above average sperm?

A

> 70% PMMNs, concentraion >100 mil/ml, >50% normal morph

28
Q

What are some other good tests to do if things are abnormal?

A 
Advanced Sperm Cell Analysis/lmaging 
Genetic tests (HYPP, HERDA, CID) 
Serum or semen for EVA 
Urethroscopy
