BSE in Females Flashcards
Why do we do breeding soundness exams?
- Document normality (BSE)
- Estimation of breeding time
- Confirm of pregnancy
- Detect abnormality (cause of infertility)
- Management of parturition
What important questions should be asked before a BSE?
- Has the animal previously been pregnant?
- Could the animal currently be pregnant?
○ Is it possible that it is too early to detect?
○ If this is possible you must consider this during your exam - don’t breach the cervix - Is there a zoonotic risk?
- Have they had pre-mating vaccinations?
What should be included in previous breeding records?
- Establish previous and current cyclicity:
- Reached puberty?
- Inter-oestrus intervals
○ Normal?
○ Prolonged?
○ Shortened?
What are the 3 venereal pathogens in mares/stallions?
Klebsiella
Pseudomonas
Taylorella (cause of contagious equine metritis)
What virus should be screen in cats?
FeLV - Feline leukaemia virus
What vaccinations are important in ewes and pigs to prevent disease in neonates?
Clostridia
Why do we carry out a general clinical exam?
- To ensure that there are no diseases or defects that preclude from getting pregnant / successfully taking pregnancy to term
○ Body size/body condition
○ Dentition, feet (predisposition to disease)
○ Ventral hernia - And to rule out hereditary defects
○ Hip dysplasia in dogs etc
What is involved in mammary gland examination?
- Correct number of teats
- Evidence of stage of oestrus cycle
- Presence of current disease
- Evidence or previous disease
What is involved in perineum examination?
- Normal alignment of the vulval lips
- Evidence of venereal pathogens
○ Coital exanthema in mares (Equine herpes 4)
○ Infectious pustular vulvovaginitis of cows (Bovine herpes virus 1)
What is normal conformation in horses?
Vulva is flat underneath perineum
Poor conformation is caused by loss of fat and muscle around perineum - vulva pulled back over pubis
What does examination of the cervix tell you?
Stage of cycle
Estimation of cervical opening at parturition
Trauma
Discharge
How can you examine the uterus?
- Trans-rectal palpation
- Trans-abdominal palpation
- Radiographic examination (small animals)
- Ultrasonographic examination
- Uterine cytology / microbiology
- Endoscopic examination
- Uterine biopsy
Why is uterine examination useful?
○ Stage of the cycle
○ Pregnancy
○ Status of involution
○ Infection (endometritis / pyometra / metritis)
What aspects of the uterus is assessed?
Shape
Size
Positition
Tone
What can radiography of the uterus detect?
Size
Position
Opacitiy
Useful for:
○ Uterine enlargement (displacement of bowel)
○ Pregnancy detection (after mineralisation)
○ Counting foetal number / confirming retention
○ (confirming foetal death but signs take few days to establish)
