Test 2: 22 male repro cont Flashcards
components of BSE in males
- id
- history
- PE
- repro PE
- behavior eval
- semen collection and eval
- conclusion/assessment
what kind of history do we care about in male BSE
- breeding history
- recent illness
- racing/training
- prior sales
- fertility of males in same herd
in rams epididymitis can be caused by
brucella ovis, actinobacillus seminis
- cull sick rams
BSE of testes includes
- visual
- palpate
- measure circumference
- freely moveable
- orientation
- disease free
bull testis size for good breeder
greater than 32 cm
scrotal width in stallion
greater than 8 cm
decrease in size of the teste is usually from
loss of germ cells
what animals can use artifical vagina to collect semen
stallion, buck, bull, ram
what animals can you use electroejaculation
bull, ram
(boar, camelid, horse with anesthesia)
what animals require manual semen collection
boar, dog
- boar can do electro under anesthesia
— are meds that can cause ejaculation
alpha adrenergic symptathetics
- xylazine, detomidine
artifical vagina are used for stallions and permits
semen collection, assessment of libido and ability to breed
- AV needs to be 45-50°C, pressure, lubrication
— does not produce a true ejaculate
electroejaculation
* volume, concentration and number will be different
how to do semen evaulation
gross eval
* motility
* volume and concentration
* pH
* sperm shape
sperm volume and concentration is not normally done with
bull, ram or buck
* or with electro
poor sperm motility
asthenospermia
how to treat congenital inguinal hernia vs acquired
aquired- surgery
congenital- reduce and may resolve on its own
enlarged scortum in adult ram
epididymitis → brucella ovis
- veneral disease- tail of epididymis affected
- should cull effected
ram lambs with epididymitis is from
actinobacillus seminis- gay behavior in yearling, oronasal ram to ram
large scrotum differentials for horse, foal, bull, sheep
horse- spematacord twisted
bull- aquired inquinal hernia, frostbite
foal- congential inquinal hernia- might self repair
sheep- epididymitis- brucella ovis
bull bse includes
- id
- history
- general PE
- examine testicles
- rectal- palpate accessort glands and inguinal ring
- semen collection
- examine penis
- semen analysis
what are the accessory sex organs in a bull
all 4
ampullae
seminal vesicles
prostate
bulbourethral glands
how to treat 12 month bull with acute seminal vesiculitis with poor semen quality but teste size 34
infection usually self resolves- antibiotics or surgery if it doesn’t
- large teste suggests good breeder, recommend new BSE once infection is cleared
mare and stallion with lesions on genitalia is usually caused by
equine herpes virus 3
* self limiting
* topical antimicrobials
* do not breed when active lesions
* leaves white scars
how to treat paraphimosis
try to get penis back into prepuce
* NSAIDs
* antimicrobials
* cold hosing
* emollients- sugar
* manually replace
