Feeding - Related Disorders Flashcards
what type of diet do horses need
- fibre based diet
- minimum of 60% for the diet
why do you need lots of fibre in a diet
- gastrointestinal motility
- buffers gastric acid
- feeds cecal microflora ( without fibre these fibres produce more acid and make a toxic environmnet
- maintains hydration
what can happen if you dont have fibre in the diet
- impaction colic or EGUS from no movement
how often should you feed horses
- frequent or continuous feeding
why do you need to feed frequently
- gastrointestinal motility
- buffers gastric acid
- feeds cecal microflora
- maintains hydration
- natural behaviour (steriotipies increases)
- insulin and leptin control
what are the feeding rules
- fibre based diet
- frequent or continous feeding
- water and salt available
- change feeds gradually
- tailer feed to need
why do you need water and salt readily available
- gastrointestinal motility
- hydration
- appetite ( without enough water appetite decreases)
- electrolyte balance
what happens if horses dont get enough water or salt
- impaction colic
- dehydration
- inappetence
- electrolyte imbalance
why should you change feeds gradually
- maintains cecal microflora - sudden changes = abrupt with toxic release and can cause laminitites and death
what happens if you change feeds too fast
- colic
- endotoxemia (from change in cecum microflora)
- laminitis
what is taylor feed to need
- 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
what can cause feed related disorders
- feed = what and how you are feeding
- management = keeping horses in isolation
- genetics = specifically related to ulcers (not as much as the other two)b
what is EGUS
- equine gastric ulcer syndrome
- nutritional causes (high NSC diet and insufficient fibres
- genetics (high strung horses)
- management causes = meal feeding and confinement
what is EMS
- 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
what are common places to see fat increase for EMS
- eye fat pads
- neck
- shoulder
- loin
- tailhead
what is DOD
- development orthopedic disease
- error in maturation or development of bone before or after birth
what are feed contributions that cause DOD
- mineral imbalances/ deficiencies
- accelerated growth rate (high DE)
- high NSC
what are genetic contributions that cause DOD
- accelerated growth rate
what are management contributions that add to DOD
- inappropriate biomedical stress
- working to early before bone develpment
- insufficient biomedical stress
what is Photosensitization
- type 1: toxic plants
-type 2 : fungus infested clover
what is big head disease
- high phosphorus then calcium in diet
- nutritional secondary hyperthyroidism
what does selinium
- insufficient or excess
- sloff hoofs
- poor coat
- wont have mane or tail
- blood test shows
what happens during vitamin E deficiencies
- no access to green forage at all = vitamin E deficiency
- equine motor neuron
- by the time you see clinical signs its to late
what is colic distress
- can range in severity from a horses need to pass wind to the necessity of surgery to correct displace, twisted or impacted intestines
