Q

why do you need lots of fibre in a diet

A
  • gastrointestinal motility
  • buffers gastric acid
  • feeds cecal microflora ( without fibre these fibres produce more acid and make a toxic environmnet
  • maintains hydration

Q

why do you need water and salt readily available

A
  • gastrointestinal motility
  • hydration
  • appetite ( without enough water appetite decreases)
  • electrolyte balance

Q

why should you change feeds gradually

A
  • maintains cecal microflora - sudden changes = abrupt with toxic release and can cause laminitites and death

Q

  • laminitis

Q

what is taylor feed to need

A
  • assesing horses body condition
  • this eliminates the idea that one food type is fit for the average horse (doesnt exists)
  • maintains condition
  • could cause to fat or to thin issues

Q

what can cause feed related disorders

A
  1. feed = what and how you are feeding
  2. management = keeping horses in isolation
  3. genetics = specifically related to ulcers (not as much as the other two)b

Q

what is EGUS

A
  • equine gastric ulcer syndrome
  • nutritional causes (high NSC diet and insufficient fibres
  • genetics (high strung horses)
  • management causes = meal feeding and confinement

Q

what is EMS

A
  • equine metabolic sydrome
  • same as type 2 diabetes
  • insulin resistance (high blood glucose, insuline releases but glucose doesnt go down = hyperglycermia)
  • profound susceptibility to laminitis
  • abnormal fat distribution

17
Q

what are feed contributions that cause DOD

A
  • mineral imbalances/ deficiencies
  • accelerated growth rate (high DE)
  • high NSC
18
Q

what are genetic contributions that cause DOD

A
  • accelerated growth rate
19
Q

what are management contributions that add to DOD

A
  • inappropriate biomedical stress
  • working to early before bone develpment
  • insufficient biomedical stress
20
Q

what is Photosensitization

A
  • type 1: toxic plants
    -type 2 : fungus infested clover
21
Q

what is big head disease

A
  • high phosphorus then calcium in diet
  • nutritional secondary hyperthyroidism
22
Q

what does selinium

A
  • insufficient or excess
  • sloff hoofs
  • poor coat
  • wont have mane or tail
  • blood test shows
23
Q

what happens during vitamin E deficiencies

A
  • no access to green forage at all = vitamin E deficiency
  • equine motor neuron
  • by the time you see clinical signs its to late
24
Q

what is colic distress

A
  • can range in severity from a horses need to pass wind to the necessity of surgery to correct displace, twisted or impacted intestines
25
what are colic behavious signs
- rolling - pawing - laying down - backing up - kicking belly - flehmen - nipping sides - standing in a stretched position - lack of defecation
26
what are colic risk factos
- previous colic - high concentrate, low roughage diet - sudden changes of feed, binges - sudden changes in level of activity - parasite infestation - stress from transport - inconsistant water supply - moldy feed - ingestion of foreign objects - insufficient exercise - poor dentation - stereotypies
27
how can minimize risk factors
- leave horse on pasture - remove parasites
28
what do you do it the horse has colic
- remove feed and water - assess horse (want to know vital signs - dehydration or shoke) - prevent self - injury ( colic horses roll, but the legs can get caught) - call a vet - provide pain relief, under vet advice ( counters activated sympathetic nervous system that subdues gastrointestinal motility)
29
what are the three different
- flatulent - too much gas - spasmodic - too much peristalsis - impaction - too little movement of digesta
30
what is the most common type of colic
- idiopathic gas or spasmodic - responds to conservative treatments
31
symptoms of flatulent colic
- gas colic or bloat - tight distended abdomen - abdomen painful to palpation - respiratory distress - elevated temperature - elevated gut sounds
32
symptoms of spasmodic colic
- intermittent bouts of mild to severe distress - TPR usually normal - relief with abdominal massage - intermittent loud tummy rumbling
33
symptoms of impaction colic
- decrease in gut sounds - relief by abdominal massage - elevated temperature - mild onset - reduced fecal output, feces dry and may be mucus covered
34
what are symptoms of large colon displacement
- mild to moderate colic - abdominal distension - mild to moderate dehydration - diagnosis by rectal palpation
35
what is a strangulating intestinal lesion
- rapidly life threatening twists that block passage of ingesta and may result in necrosis of surrounding tissue
36
what is strangulating lipoma
- stalk that wraps around colin - requires early referal and surgical correction
37
what is enteritis
- inflammation of the small intestine - may be associated with infection by salmonalla or clostridia or infestation of endoparasites
38
what is colitis
- inflammation of the large intestine - often associated with the infection of salmonella or clostridia or anti inflammatory drugs
39
what is colon torsion
- brood mares - pre and post parturition
40
how can you control and provent colic
- exercise - fibre - water and salt
41
what happens when there is a insufficient gastrointestinal motility
- gas colic - spasmodic colic - impaction colic - GI torsion
42
what happens during a carb overload
- gastric digestion/ absorbtion insufficient, simple carbs get to cecum - dermentation increases lactic acid and bacteria that break down simple carbs - pH decreases and resident bacteria dies off - toxins enter circulation and colic endotoxemia and laminitis starts
