33
Q

Ulcers

  • diseases (Rabies)
  • weeds (Australian stringhalt)
  • ataxia, incoordination,breathing difficulties
35

2) face flies and horn flies
3) horse flies, deer flies, black flies, gnats , mosquitos

37
Q

Mosquitos

- breed, carry and symptom

A
  • breed in slow moving or standing water
  • carry several encephalitides that can cause inflammation of the brain, or death
  • horse will press head against the wall do to swelling
38
Q

Fly control

- successful completion of life cycle requires:

A
  • appropriate breeding material (water)
  • optimum moisture
  • adequate warmth
39
Q

Ticks

A
  • controlled using insecticides
  • tend to be found in manes, forelock, under tail, ears and other warm areas
  • spread Lyme disease
40
Q

Lice and mites

A
  • found under mane
41

Blister beetles

A
  • irritating secretion causing fluid-filled eruptions on skin
  • cantharidin poisonous when eaten
  • feed on alfalfa
  • 1/2 of blister beetle can be deadly to horse if ingested
  • boils erupt on skin if come to external contact
42
Q

Good sanitation

A
  • removal of manure
  • clean feeders, and corners in barn around water
  • spread manure thinly on pastures, this exposes and kills eggs but have to wait a period of time before letting horses graze again
  • horse manure composts in demand
43
Q

Non-chemical control

A

1) screening (fly masks, fly sheet, boots)
2) fans directing blasts downward/outward
3) stick fly tapes
4) biological control
- parasitic wraps (consume larvae of external parasites, release on top of manure pile)

44
Q

Insectides

A

1) residual insecticides
2) sprays/fogs/mists -> adult flies
- pyrethrins, permethrin
- little to no residual
3) fly baits -> granules

45
Q

Different type of fly sprays

A
  • oil based (endure), water based, all natural, ointment, and spot treatments
46
Q

External parasites

A

1) flies
2) Mosquitos
3) ticks
4) lice and mites
5) blister beetles

47
Q

1) Detrimental parasites
2) bot flies
3) ascarids (roundworms)
4) strongyles (bloodworms)
5) pinworms
6) strongyloides (threadworms)
7) tapeworm

48
Q

Detrimental parasites

A
  • lowers feed efficiency
  • reduces performance
  • affects digestion (inside GI tract)
    - causes impaction (impaction colic)
  • can kill horse
49
Q

Adult bot flies

A) where they lay eggs and why

A

A) females lay yellow-white eggs on forelegs, chest, necks, bellies, hind leg and flanks (all places where horses can lick)

50
Q

BIGGEST ISSUE OF bot fly

A

1) biggest issue is within stomach itself, will burrow into stomach lining
- in severe infestations, perforations of stomach lining may happen

51
Q

Controlling bot flies
A) break the cycle
B) internal medication

A

A) sponging areas will mimics horses tongue, will die in external environment
- removal with bot knife, or pumice stone

B) ivermectin (only one that targets bot flies)
- moxydectine

52
Q

Ascarids (roundworms)

- damage

A

A) primarily affects young foals/growing horses
B) damages include
- larvae main problem during migration
- physical damage, inflammation and scarring liver and lung tissue (not only GI tract)
- adult worms (decreased feed absorption, intestinal blockage -> colic)
- if they end up in a lung horse will cough them up and reingest them

53
Q

Controlling ascarids

A
  • eggs are resilient and remain ineffective for years
  • deworming at 8 weeks and at least every two months was the old method, but since they are becoming resistant to the dewormers must do a fecal analysis
  • larvae must return to GI tract before dewormers works (damage already done)
54
Q

Strongyles (Bloodworms)

A
  • most significant and common
  • most serious threat of all parasites
  • larvae are resistant to most weathers (survive freezing, but killed by hot and dry summers)
55
Q

Large strongyles
A) cycle
B) symptoms

A
  • most significant (strongylus vulgaris)
    A) - larvae burrow into small arteries into gut wall (burrow through GI tract into bv)
  • return to large intestines

B) loss of appetite, anemia, emaciation, incoordination/lameness in hind legs (resembles neurological issue), restricts vessels of muscles in hindquarters (blood flow blockage)
- often mistaken for EPM

56
Q

Small strongyles
A) Cycle
B) damage

A

A) don’t migrate beyond intestinal lining
- damage less severe, don’t get into blood vessels

B) diarrhea and increases incidences of colic

57
Q

Ways to eliminate risks of both types of strongyles

A
  • they are susceptible to environmental breakdown (hot and dry)
  • manure disposal
  • deworming most effective elimination
58
Q

Pinworms affects/location

A
  • not terribly harmful, but causes lots of itching and discomfort
  • found largely in colon and rectum
  • lay sticky eggs around anus
  • severe irritation around tail (tail rubbing)
59
Q

Strongyloides (Threadworm)
A) infects ages ?
B) damage
C) prevent

A 
A) infects young foals 4-47 days old
- get it from dams milk and bedding
B) migrate through lungs and SI
- horses develop immunity by 60-90 days 
- causes diarrhea (dehydration) 
C) deworm dam to prevent in foal
60
Q

Tapeworm

A
  • very problematic in horses
  • intermediate host is oribatid mites
  • ulceration of large intestine and cecum
  • colic and severe form of intestinal blockage
  • telescopic secum colic: secum is pulled like a sock inside out and will stick together
  • most problems in the hind gut
61
Q

Prevention and Control of external Parasites

A

1) climate, season, humidity, rainfall, age and stocking density
2) interruption of life cycle
- manure disposal (composting and spreading)
- dragging pastures
- deworming
3) fecal analysis
- fecal egg re-emergence
- fecal egg count (deworm appropriately)
4) separate horses by class
5) pasture rotation
6) don’t feed horses on the ground
7) keep water sources free from fecal material
8) quarantine new horses; do fecals and turn out if necessary

62
Q

Resistance to dewormers

A
  • huge issue
  • fecal egg count evaluates effectiveness of dewormer
  • if egg count reduced by less than 80% ..resistance is probable
63
Q

RESISTANCY CHART

A

Result FEC. Risk. Result

Low. 500. High risk. Treatment

64
Q

Classes of dewormers

A

1) benzimidazoles
2) pyrimidines
3) avermectines
4) moxidectin

65
Q

Benzimidazoles

A
  • most common is fenbendazole or oxibendazole ( panacur, safeguard or anthelcide-eq)
  • won’t control bots or tape worms
  • Require high dosages to control ascarids
  • safer for horses
  • less affective bc resistance
  • phenylguanidines -> natural in body
66
Q

Avermectins

A
  • very effective
  • bots, strongyles, pinworms, threadworms, ascarids
  • relatively safe
  • ivermectins
  • compounded with praziquantel (Equinox plus)
  • praziquantel for tape worms
    - double dose of pyrantel pamoate
67
Q

Pyrimidines

A
  • effective against ascarids, strongyles, threadworms and pinworms
  • double dose controls tape worms
68
Q

Moxidectin

A
  • for bots strictly
  • margin of safety much lower 5x versus 20-60x
  • do not give to young or old
69
Q

Signs/Symptoms of worm infestation

A

1) heavy fecal egg count
- low body weight, pot belly, rough hair coat, capillary refill low, lethargic and dull eyes
2) develop slowly
3) prone to colic, susceptible to diseases and lameness
