Q

Acute vs chronic signs and treatment of metritis

A

ACute: septicaemia/toxaemia, anorexic, high or low temp depending on if in shock, bloody discharge
- Affressive antibiotics and anti-inflammatories, oxytocin, fluids orally

Chronic: bright and eating still; low grade creamy discharge
- Long term antibiotics, cull

Q

Signs of urolithiasis and which individuals do we see it in

A

straining, tail flicking, rectal prolapse, abdominal enlargement, recumbency
+ can eventually get rupture and uroperitoneum

Just see it in castrated males due to narrow urethra

17
Q

Dealing with urolithiasis

A

Correct diet
Urine acidification using ammonium chloride
Can do cystotomy

18
Q
A
18
Q

Risk factors for pelvic organ prolapse

A
  • High perineal score
  • Low body condition
  • Mycotoxins e.g zearalenone is oestrogenic to cause straining
    Constipation/enteritis

Increased prevotell

19
Q

How can we manage perineal score 3 pigs before farrowing

A

Give anti-inflammatories in 3 days pre-farrowing

20
Q

What type of penis do boars have

A

Fibroelastic penis with corkscrew at end

21
Q

What organisms are involved in acute mastitis

A

E coli
Klebsiella
Staph

Related to poor hygiene and teat damage by piglets nipping

22
Q

When do we see acute mastitis and how do we treat

A
  • Immediate antibiotics and anti-inflammatories, fluids, milk supplement piglets

Happens in 1-3 days post-farroing usually

23
Q

What happens in MMA syndrome

A

Circulating endotoxaemia inhibit prolactin production

> Could be due to metritis or mastitis
Or due to fat sows stopping eating after parturition causing gram -ve die off in gut and release of endotoxin

24
Q

Clinical signs of MMA ad how to treat/manage

A

Lethargic, dull, anorexic sows with udder oedema + hungry piglets

Treat with anti-biotics, anti-inflammatories, oxytocin and mild replacers
- Make sure sows don’t get too fat before farrowing; want at 3-3.5 BCS

25
Q

LEgal requirements of pig keeping to keep in mind for met pig owners

A
  • Need herd number
  • ban on kitchen waste feeing/mammalian protein
  • 20 day standstill after moving onto premises
    Walkng license
    Need ear tag/tattoo if over one year; or if going to slaughter at any age
26
Q

What BCS do we want a pet pig through adulthood and waht should their feed intake be as a % BW

A

Up to age of 8 BCS 2-2.5
1% BW intake

Once >8y/o let them go 2.5 to 3 BCS

27
Q

What parasites affect pig sin

A

Sarcoptic mange
Lice - haematopinus suis

See flaky, dry skin

28
Q

What is dippity pig

A

Autoimmune condition causing necrotising cellulitis and dermatitis in young pigs
Very painful
treat with steroids, antiseptic washes
Often self heal in a week

29
Q

How to treat erysipelas

A

Penicillin
+ review vaccination protocol

30
Q

What is a common cause of pet pigs going blind

A

Obesity; causing entropion

31
Q

What can cause congenital tremor

A

Congenital tremor
- Atypical porcine pestivirus
- CSF

32
Q

What nutritional things can cause neuro issues

A

Hypoglycaemia
Water deprivation

33
Q

What bacterial things can cause neuro issues

A

Strep suis
Abscesses e.g from tail bite, pressing on spinal cord

34
Q

What viral cause can cause neurological issues

A

Aujesky’s

35
Q

Where do we trim tusks to

A

2cm above gum margin to avoid entering pulp

36
Q

What gaseous anaesthesia do we use for pigs

A

Isoflurane
- Can trigger malignant hyperthermia if carrying gene

37
Q

What injectable anaesthesia do we use in pigs

A

Azaperone then ketamine for deep sedation

Can do ket butorphanol and xylazing in combo for anaesthesia
