Study for a Career in Animal Health or Welfare
This is a comprehensive and practical course for anyone who wants to better understand the health and well-being of animals.
The course is designed to provide a foundation for employment in any type of animal care job including:
- Pet care,
- Farm livestock, and
- Wildlife (captive or free).
By studying this course, you will learn about:
- Animal anatomy and physiology.
- Diagnosing animal diseases.
- Natural animal health care.
- Animal health and care.
- Animal psychology and/or animal feed and nutrition.
Studying this course will give you a thorough understanding of the process involved in maintaining animal health.
Note: Animal Health Reference books are available for sale in the ACS Bookshop
This is an experiential learning-based course. Throughout your studies you will have the opportunity to network with and learn from a variety of industry professionals. Establishing real-world relationships and confidence is key to career success.
Modules
Note that each module in the Certificate in Animal Health is a short course in its own right, and may be studied separately.
How is a clinical examination carried out?
Recognising the differences between what is normal and what is abnormal about an animal or group of animals forms the basic foundation for good animal husbandry and veterinary medicine. Using your powers of observation can be very important for the early recognition of subtle abnormalities. Observation of behavioural changes, changes in energy levels, elimination changes (urine and faeces) and physical changes are important, but don't just evaluate the animal, evaluate its environment, too. Ask questions such as:
- How is the animal housed?
- What are the climatic conditions?
- What plants do they have access to?
- Are they hand fed, or do they graze?
This type of information is very important in the process of determining what disease processes are occurring. In addition to evaluating the animal’s environment, recording and compiling animal information such as type and condition of animals, age, sex, number of affected animals, and progression of disease are the first steps in the disease recognition process.
When dealing with diseased animals it is important to remember that some diseases are zoonoses (they are transmissible to humans). When undertaking a physical examination or postmortem examination, wear protective clothing, gloves and overalls.
Physical examination
A physical examination is the next step in identifying diseases or conditions in animals. The veterinarian will examine the whole animal and not just the obviously affected area.
It is helpful to start by examining the non-painful areas and then moving on to those areas that show discomfort. If an animal is in a lot of pain, the veterinarian may suggest lightly anesthetizing the animal so a more complete exam can be safely conducted.
The exam will generally include:
- Weighing the animal.
- taking the temperature.
- Listening to the heart and lungs.
- Checking eyes, ears, nose, etc.
- Examining the skin for any trauma or puncture wounds.
- Examining all the limbs.
- Watching the animal move about the exam room or outside on the grass.
- Performing special manipulations of various body parts e.g., neck, limbs.
Postmortem or Necropsy
Autopsy refers to an examination of a deceased human. When the examination is done on a deceased non-human animal, the procedure is called a necropsy. Necropsies are generally conducted by veterinarians or suitably trained government inspectors.
There will be times when neither is available to you, and you may need to undertake specimen collection yourself. In this case it is important to understand what to samples to collect and how to collect, preserve, and send specimens for laboratory analysis.
Always seek the advice of a veterinarian, relevant government inspector, or the testing laboratory, to ensure you are taking the correct samples and using the appropriate transport media.
Various methods may be used to perform necropsies and, as long as all organ systems are examined thoroughly, each technique has its merits. Ideally, necropsies should be conducted in a postmortem room, but if this is not possible, they may be carried out in the field. It should be remembered that on-farm examinations may be limited and may only involve sample collection.
The value of undertaking a postmortem allows for a concise interim pathology report to be produced. This report should describe lesions, outline preliminary conclusions and, if possible, include a morphological diagnosis.
Microbiology, parasitology, biochemistry, histopathology etc. may then be needed to assist in establishing a diagnosis.
We discussed earlier how a physical examination of a live animal may be undertaken but if an animal is presented to you is already dead, it is still important to make a thorough external examination of the animal. Questions to ask include:
- How long has it been dead?
- Has rigor mortis set in?
- What is the body condition of the animal?
- Is sternal or lateral recumbency exhibited?
- Are there any wounds or injuries?
- Are they old or relatively recent?
Note any discharges from body orifices. Be aware that these may be a result of post-mortem changes rather than part of a disease condition. When an animal dies the body sphincters and muscle tone relaxes, allowing the stomach contents to regurgitate and urine/faeces to discharge from the body.
When performing the postmortem or necropsy it is very important to be methodical. Take care not to cross-contaminate the organs with dirty equipment and to avoid contaminating the organs with intestinal contents.
