B2 Flashcards
What is EGUS? How many types exist?
Equine gastric ulcer syndrome
- equine squamous gastric disease which can be primary or secondary
- equine glandular gastric disease
What does it mean when we say “equine squamous gastric disease which can be primary”?
Management of nutrition
What does it mean when we say “equine squamous gastric disease which can be primary”?
Management of nutrition
What does it mean when we say “equine squamous gastric disease which can be secondary”?
delayed gastric emptying
What is equine squamous gastric disease?
ESDG
non-glandular part is not protected against hydrochloric acid and peptic ulcers are typical here and are usually related to nutrition causing abnormal HCl production, causing a low pH.
Which horses are more prone to develop the equine squamous gastric disease?
Racehorses, horses that train on an empty stomach and horses that are fed unregularly
Why are racehorses more prone to get the equine squamous gastric disease?
they are fed low-fibre hay and large amounts of concentrates (starch and sugars) which requires a low amount of chewing → less saliva produced for buffering → low pH.
Why are horses that train on an empty stomach more prone to get the equine squamous gastric disease?
It can lead to increased pressure in the stomach and splashing of the gastric acid to the non-glandular area
Why are horses that are fed less prone to the equine squamous gastric disease?
Because horses that aren’t fed, will fill the stomach will acid, which will reach the non-glandular part
What is equine glandular gastric disease?
Ulcers of the glandular stomach is usually secondary to other primary intrinsic factors
Name other primary intrinsic factors of equine glandular gastric disease:
- Circulation disorders
- Abnormal prostaglandin levels
- Oesophageal rupture
- Reflux from small intestine containing bile acids
What are clinical signs of equine gastric ulcer?
- Colic signs
- loss of appetite
- recumbent
- weight loss
- poor performance
- aggressive or nervous behaviour.
How much roughage/pasture would you give a horse with equine gastric ulcer?
Pasture for 16+ hours/day
1.5 kg/100 kgBW
How much CP would you give a horse with equine gastric ulcer?
17-20%
How much Ca would you give a horse with equine gastric ulcer?
6-14 mg/kg DM
What type of roughage will you give?
Aflalfa
It increases calcium, protein and phosphate as a buffer.
What is dysbiosis?
An imbalance of the microorganisms within the gut
What causes dysbiosis?
Caused by excess grain/high starch feeds.
How is dysbiosis treated?
Treatment includes probiotics or the caecal contents of a healthy horse to build up the microflora.
what can cause diarhoea?
Change in absorption capacity of the intestines, often seen in older horses, in use of antibiotics, infections, parasites, ingestion of sand
What are impactions, and which types excist?
obstructions in the bowel
Can be gastric, ileac, caecal or in large colin (which os more common)
How to treat impactions:
- Analgesics or laxatives via nasogastric tube
- Hold back feed until impaction cured
- Psyllium pellets help improve transit time because of water soluble fibre, causing swelling of fibre and VFA production
What is advised to do post-treatment of impaction?
Give good quality hay not too high in fibre, and highly digestible fibre such as growing grass and legumes
How to prevent impaction:
Dental care
Fresh water at all times
Good quality hay
Regular exercise
