Animal Health: JAMB Agricultural Science Questions, Answers & Notes

What Animal Health covers in the JAMB Agricultural Science syllabus

A healthy animal is free from disease and functioning normally (shiny coat, good appetite, alertness); a disease disturbs this normal functioning. Diseases may be infectious/pathogenic (caused by living pathogens — bacteria, viruses, protozoa) or nutritional/deficiency (lack of nutrients). Parasites live on the host: ectoparasites (ticks, lice, mites — on the outside) and endoparasites (tapeworms, roundworms — inside); a vector (e.g. the tsetse fly, which spreads trypanosomiasis) transmits disease between animals. Signs of ill health include loss of appetite, dullness, weakness and abnormal droppings. Prevention and control include vaccination, deworming (against worms), dipping/spraying (against ticks/lice), good sanitation, quarantine of sick animals, and treatment by a veterinary doctor. Diseases cause deaths, reduced production and economic loss, so health care keeps animals healthy and productive.

For Animal Health, JAMB expects you to be able to:

• Define animal health and disease and their causes
• Distinguish parasites (ecto/endo), hosts, vectors and pathogens
• Describe signs of ill health and disease prevention/control

Key facts & revision notes: Animal Health

These are the recurring points our Animal Health questions test — revise them until each feels automatic, then practise the questions above to lock them in.

• A healthy animal is free from disease and functioning/producing normally.
• A disease is any condition that disturbs the normal functioning and health of an animal.
• Infectious (pathogenic) diseases are caused by living organisms (bacteria, viruses, etc.).
• Nutritional (deficiency) diseases are caused by a lack of essential nutrients.
• Pathogens are disease-causing organisms (bacteria, viruses, fungi, protozoa).
• ticks, lice, mites) live on the outside of the animal's body.
• tapeworms, roundworms) live inside the animal's body.
• The host is the animal on or in which a parasite lives and feeds.
• tsetse fly) transmits pathogens from one animal to another.
• The tsetse fly transmits trypanosomiasis (nagana/sleeping sickness) in cattle.
• Vaccination gives animals immunity against specific diseases (prevention).
• Signs of ill health include loss of appetite, dullness, weakness, and abnormal droppings.
• A healthy animal shows a shiny/smooth coat, good appetite and alertness.
• Deworming removes internal parasites (worms/endoparasites) from animals.
• Dipping/spraying with acaricides controls external parasites like ticks and lice.
• Clean housing and good sanitation reduce the spread of diseases and parasites.
• Quarantine/isolation of sick animals prevents diseases from spreading to healthy ones.
• A veterinary doctor (vet) diagnoses and treats animal diseases.
• Diseases cause animal deaths, reduced production (milk, eggs, meat) and economic loss.
• The aim of animal health care is to keep animals healthy and productive.

Worked examples

Three Animal Health questions with the answer and a short explanation, so you can see how the topic is set before you practise the full set.

How Animal Health is tested in JAMB Agricultural Science

Our Animal Health bank holds 20 questions (1 easy, 11 medium, 8 hard). JAMB Agricultural Science typically returns to Animal Health year after year, so steady practice on this topic is high-value revision. Questions are multiple-choice with four options, and at UTME pace you get roughly 40 seconds each — which is why timed practice matters.

How to answer Animal Health questions

Work the stem first and predict the answer before you look at the options; then eliminate the ones that contradict the key facts above. Watch for “which is not…”, “all of the above” and “except” style stems, which are where rushed candidates lose easy marks on Animal Health. If a calculation or a precise definition is involved, work it from first principles rather than guessing from a half-remembered rule. When two options look right, re-read the stem for the qualifier that separates them — JAMB rarely repeats an option by accident. If you are still unsure, eliminate the two weakest choices to lift your odds, flag the question, and move on; never burn a full minute on one Agricultural Science item when the exam gives you about forty seconds each. Then come back to flagged questions with whatever time remains. The single most reliable way to get faster at Animal Health is repeated timed practice, so use the button above until the recurring patterns feel automatic.

Common mistakes to avoid in Animal Health

The errors that cost marks on Animal Health are usually careless rather than conceptual: misreading a negative stem, confusing two similar terms, or rushing a definition you actually know. Candidates also over-rely on “expo” and last-minute cramming instead of understanding the topic — which fails the moment JAMB rephrases a familiar idea. Treat every option as a claim to be checked against the facts above, keep your working tidy for any calculation, and don’t change a considered answer on a hunch. Above all, revise Animal Health actively by answering questions, not just by re-reading notes — recall under time is what the exam rewards.

Frequently asked questions

Is Animal Health part of the JAMB Agricultural Science syllabus?
