ANSC 3

VOCABULARY YOU SHOULD KNOW!

Review vocabulary commonly used in animal health

Determine and define an infectious disease• 1. The infectious disease should be

detectable in sick animals not healthy animals

• 2. It should be possible to isolate and culture the organism

• 3.Organisms taken from the culture and introduced into a healthy animal cause disease in the healthy animal

• 4. The same organism should be isolated from this second animal.

How are they made?• Take a weaken strain of the infectious agent

and inject it into a healthy animal• Healthy animal’s immune system will react

creating antibodies against the agent• Vaccine’s may need to be administered

periodically WHY DO YOU THINK THIS?

Strangles- Bacterial, usually affects young horses, anorexia, fever, nasal discharge, swollen lymph nodes

Kennel Cough- Viral, dry hacking cough, fever Can lead to secondary infections

E. coli- Bacterial, usually among young animals less than 2 weeks old severe diarrhea, dehydration, anorexia, may cause death !

Valley Fever- Fungal, most prevalent in the Southwest US, may infect the skin with lumps and abscesses

Roundworm- Parasites, Diarrhea, vomiting, potbellied appearance, dull coat, poor weight gain

Can you define these words? Please give brief definitions of the ones you know in your notes!

materials) Trauma to the jaw Infection Cancer Signs: Inability to eat or dropping food out of the mouth Stops eating “hard” food items like carrots, pellets Drooling (caused by pain from ulcerations on the inside of

the mouth) Visible overgrown teeth Face wet from tears spilling onto face (elongated tooth roots

can block tear ducts) Gradual weight loss/small stool production

Diagnosis: Thorough examination of the mouth

(anesthesia may be needed) X-rays of the head (anesthesia required) Treatment: Correct the diet Grind down overgrown teeth (anesthesia

usually required) Permanent removal of abnormal teeth Medical therapy as needed to treat infected

teeth or to control pain during healing

Managing Diseases and Parasites

When was the last time that you were sick?

How and why did you get infected?

Discuss signs of good and bad animal health.

Identify diseases transmissible from animals to humans and humans to animals.

Describe common animal parasites and diseases.

List ways to prevent and treat diseases and parasites.

VaccinatingVentilationZoonoses

I. Being able to recognize when your animals need medical attention is important to the business.•Many diseases and parasites are treatable if caught early

Keep the sickness from spreading act quickly at the first signs.

A. Signs of good health include:

1. Contented animals look free from all anxiety.

• Some animals have specific signs

Pigs will curl their tails when they are content and sheep will stay quiet.

A. Signs of good health include:•2. Normal feces and urine should be seen.

This will vary with diet and type of species

•3. Body temperature, respiration, and pulse rate should be monitored because unusual highs and lows can be symptoms.

•4. Alertness can be judged by checking if an animal perks its ears when you draw near.

•5. The skin and coat of most animals should be oily and elastic like.

A. Signs of good health include:•6. The animal’s eyes should be bright

and their membranes pinkish.•7. One of the easiest things to notice is

when an animal goes off feed.

All healthy animals should eat eagerly when fed and ruminants should be seen chewing their cud.

1. When animals stray off by themselves and hold their head down it is a good sign that they are not well.

2. Lower production of milk is also not good.

3. A rough-looking dull hair coat or skin that stays up when pinched are signs of poor health.

4. Discolored feces or urine can be obvious signs of trouble.

5. Glassy eyes are sometimes a sign of poor health.

6. An animal that is difficult to get up and walks slowly may also indicate that something is wrong.

II. Many diseases are passed between animals and humans. • Modes of Transference

They are usually transferred by way of meat, milk, or eggs.

close contact is made insects carrying them from animal to animal.

Zoonoses are diseases that animals can transmit to humans.

Some of the diseases include:•1. Tuberculosis•2. Anthrax•3. Rabies•4. Brucellosis (Bangs)•5. Nine Mile Fever (Q Fever)•6. Parasites like Ringworm

B. Three kinds of diseases are transferred from humans to animals.

Protozoa, bacterial, and viral infections are the three.

Protozoa infections like the animal parasite that causes amoebic dysentery can be shared.

Bacterial infections like the streptococcus that causes scarlet fever in humans can be passed to an animal and then produce large problems when humans consume milk or other products.

Viral infections are being researched closely for more shared ailments between humans and animals but we know that chimps can get common colds and dogs can get the mumps virus.

III. There are some common diseases and parasites with specific symptoms.

Diseases can be contagious or non-contagious. • Contagious diseases are diseases that can be

passed from one animal to another. • Non-contagious diseases are diseases that

cannot be transferred from one animal to another.

Important to determine what kind because contagious animals need to be separated to prevent spreading the disease.

Contagious diseases are usually caused by bacteria or viruses.

They spread from animal to animal by simple contact or shared facilities.

Diseases that are not contagious, like scurvy, are sometimes caused by a vitamin or mineral deficiency.

They may also be caused by ingestion of metal, poisonous plants or animals, or open wounds the animal may have.

General symptoms specific to disease include:• 1. Animal losing fetus• 2. Shaking• 3. Coughing• 4. Poor growth or decrease in production• 5. Rough coat

Parasites can be internal or external. Internal parasites are ones that live

inside the animal like flukes and roundworms.

External parasites are ones that live outside the animal like fleas and flies.

Symptoms of parasites may include:• 1. Observing the parasite on an animal.• 2. Diarrhea, worms in feces, or bloody feces.• 3. Loss of weight.• 4. Decreased production, growth, and

reproduction.

IV. Whenever possible prevention of disease should be done.

Ways to prevent diseases and parasites:• Natural immunity- immunity to a specific

disease is inherited from parent to offspring• Species immunity- a disease that affects one

species does not affect other species

2. Vaccinating is injecting a disease organism that has been modified into an animal to prevent the animal from getting the disease later.• Biologics are the medical preparations

made from microorganisms and their products, like vaccinations and serums.

3. Sanitation management is important to preventing diseases and parasites. • Sanitation is the act of cleaning or sterilizing

an area.

4. Ventilation is also important to manage. • Ventilation is causing air to move through a

building. 5. Keep all housing facilities clean and

use dry bedding.

6. Disposal of manure is very important. If animals are made to live in their manure it will surely cause diseases to transfer rapidly because it is the optimal environment for diseases and parasites to thrive in.

7. Using the same pasture for the same species over and over could be dangerous. Try to rotate animals to break a parasitic life cycle.

8. Always dispose of carcasses in a sanitary way.

Drugs for treatment come in many forms like pills, powders, and liquids.

Before giving any medication, be sure to check if there is a milk or meat hold associated with the drug.

2. There are many ways to inject drugs.

They are all named according to how they are injected. •Intravenous means injected into the vein.

•Intramuscular means injected into a muscle.

•Subcutaneous means injected under the animals skin.

Intradermal means injected between layers of skin.

Injections into an animals rumen are called intraruminal.

Injections given in the abdominal cavity are called intraperitoneal.

4. Checking respiration and pulse can be done without any expensive equipment.

For respiration, simply watch how many times the animal breathes in 1 minute.

For pulse you can often hold your ear against the animal and listen for the heartbeat.

5. Always restrain animals properly to prevent hurting the animal or yourself.

6. Certain ailments can be treated with little knowledge, but other problems require the expertise of a veterinarian. • A good management practice is to know

your own limitations.
