Q

How to manage internal parasites in mature horses > 3yr?

A
  • small strongyles
  • Fecal Egg Counts to determine high shedders (>500 epg feces)

Q

How to manage internal parasites in immature horses < 3yr?

A
  • ascarids
  • treat anthelmintic at 2-3 months of age & every 2 months thereafter until 12 months old
  • fenbendazole, pyrantel pamoate, macrocyclic lactones
  • FEC to establish small strongyle burden at 10-12 months of age
  • FECs 2-3x/yr from 1yr-3yr to help establish low vs high shedder & what tx currently required
  • tx 2-4x/yr from 1-3yr

A
  • increased bone density, more social, easier to train/handle, fewer undesirable behaviours, maintain level of fitness
17
Q

What are the benefits of exercise?

A
  • if turnout not possible (or in addition to!)
  • increases level of fitness
  • improves behaviour
18
Q

A

head tossing & cribbing

21
Q

What should be done to prevent sick/injured horses?

A
  • caretakers need to be able to recognize abnormalities & apply basic first aid
  • regular close inspection is key to detection
  • vet info should be posted in the barn for ease of access
  • make sure your clients are comfy calling - even w/ “silly” questions
22
Q

What are common signs of illness?

A
  • change in behaviour, inappetence, change in consistency of feces, unexplained (sudden) weight change, pain or discomfort, signs of colic, lameness, swellings, discharge from eyes, ear, nose, coughing or difficulty breathing, fever

A
  • chlorhex
  • bandage material (non-stick pads, gauze, vet wrap, tape, pillows, & polo wraps)
  • poultice material (sugar & iodine, aminalintex pads)
  • scissors
  • duct tape
24
Q

What is biosecurity?

A

management practices that reduce the risk of spread of infectious disease

25
Q

What does the risk of the spread of infectious disease depend on?

A

number of horses, age groups, housing, movement of horses, vaccination status, quarantine protocols, movement of people, protocols for sick horses

26
Q

What is a closed herd?

A
  • no movement of animals or introduction of new animals from external sources
  • risk of disease comes from the environment or insects
27
Q

What is an open herd (commingling)?

A
  • new horses are routinely introduced to the herd or horses from different locations are brought together
  • risk of disease spread from horse to horse
28
Q

How do we decrease the exposure to pathogens on a farm?

A
  • separation of new arrivals, separation of potentially higher risk horses, separation of susceptible horses, cleaning and disinfection, hand hygiene, PPE, access control (limit public access), traffic flow, pest management, pasture management
29
Q

How do we decrease susceptibility to disease?

A
  • nutrition, manage underlying disease, reduce stress, parasite control program, annual horse health
30
Q

how do we increase resistance to disease?

A

vaccination

31
Q

Examples of notifiable diseases?

A

strangles (Streptococcus Equi Equi), West Nile Virus, Equine herpes myeloencepalopathy, Anthrax, EIA, rabies, trichinellosis
