Grade 10 Agriculture – General Animal Health Quiz

Vaccination trains the immune system to recognize and fight specific pathogens, helping prevent disease; it does not cure an active infection or replace proper husbandry.

Rotational grazing breaks the life cycle of many parasites by moving animals away from contaminated pasture, lowering parasite larvae exposure.

Mastitis causes inflammation of the udder and changes in milk appearance and consistency; these are classic diagnostic signs.

Rabies is a viral disease transmitted from infected animals to humans, often through bites; it is a well-known zoonosis.

Quarantine prevents introduction of disease to the herd by allowing time to observe and treat any illnesses before contact with other animals.

East Coast fever is transmitted by infected ticks (mainly Rhipicephalus species) which feed on cattle and spread the parasite.

Deep burial away from water and people reduces the risk of disease spread and contamination of water supplies and limits scavengers.

Good records allow farmers to know when animals were treated or vaccinated and to identify health trends requiring action.

These are typical signs of illness in poultry indicating stress or disease; such birds need inspection and possibly treatment.

Biosecurity includes practices such as controlling access, cleaning equipment, and separating sick or new animals to reduce disease risk.

Use of approved acaricides at recommended intervals reduces tick and lice burdens when used correctly as part of an integrated program.

Lower temperatures slow multiplication of spoilage and disease-causing bacteria, improving milk safety and shelf life.

Heavy worm burdens cause poor nutrient absorption and anemia, leading to stunted growth, rough hair, and pot-belly in young stock.

Fresh air and adequate space reduce humidity and pathogen build-up, lowering risk of respiratory infections.

Quarterly deworming is a common schedule for many smallholders, but timing should follow veterinary advice based on local parasite levels.

Pathogens can be carried on shoes and clothing; controlling visitor access and requiring footwear cleaning reduces disease introduction.

Rabies often causes behavioral changes, aggression, salivation and difficulty swallowing; these signs require urgent veterinary and public health response.

Balanced feeding provides the nutrients needed for immune function, growth and recovery from illness.

Hygiene and disinfection prevent transferring pathogens between animals and protect the handler from zoonotic infection.

Severe sudden signs require urgent veterinary assessment to diagnose and treat potentially life‑threatening conditions.

Short pasture and good overall herd condition reduce tick habitat and improve animals' ability to cope with infestations; integrated approaches work best.

Cleaning, drying and disinfecting reduces buildup of pathogens and lowers disease risk among young, vulnerable animals.

Overuse or misuse of antibiotics drives resistance, meaning common drugs may fail, threatening animal and human health.

Lameness commonly shows as reluctance to walk, limping or putting less weight on a limb and requires inspection and treatment.

East Coast fever is a tick‑borne disease; the recommended prevention is vaccination (often the infection-and-treatment method) plus tick control. Antibiotics do not prevent infection, and herbal remedies or salt licks are not effective prevention.

Mastitis causes inflammation of the udder; typical signs are heat, swelling, pain and abnormal milk such as clots or watery, discoloured milk. Respiratory signs or hair loss are not typical for mastitis.

Internal parasites require appropriate anthelmintic drenching, ideally guided by faecal egg counts and veterinary advice to avoid resistance. Sprays and antibiotics do not treat gut worms.

Rabies is a viral zoonotic disease commonly spread by bites from infected mammals such as dogs; mastitis and East Coast fever affect animals and are not transmitted to people by dog bites, while foot‑and‑mouth mainly affects cloven‑hoofed animals.

Milking dairy cows at least twice daily helps maintain udder health and reduce mastitis risk; infrequent milking leads to udder congestion and increases infection risk.

Quarantine means isolating new or sick animals to observe for disease and prevent introducing infections into the herd. Immediate mixing or only vaccinating without isolation increases disease risk.

Antibiotics have specific withdrawal periods to ensure residues fall below safe limits before milk or meat enters the food chain. Ignoring instructions risks unsafe products; dilution is not effective.

Ticks are major vectors of diseases such as East Coast fever and anaplasmosis in cattle. Lice, fleas and mites cause problems but are not the main spreaders of these tick‑borne infections.

Standing to be mounted is the classic sign of standing heat in cows and indicates readiness for insemination. Changes in appetite or lameness are not reliable indicators of oestrus.

Footrot is caused by bacteria that invade the hoof in wet, dirty conditions. It is not a virus or internal worm problem, though good nutrition helps recovery.

Ticks are best controlled with approved acaricides applied correctly and by managing grazing and pasture to reduce tick habitats. Vitamins or extra feed do not control ticks.

Deep burial or controlled burning prevents disease spread and contamination. Leaving carcasses exposed or dumping in water spreads pathogens; feeding to animals risks further disease.

Mastitis is inflammation usually caused by bacterial infection entering through the teat. Environmental factors and hygiene affect risk, but sunshine or extra minerals do not directly cause mastitis.

Good records help monitor health, schedule vaccines, detect disease trends and improve productivity. Records are practical management tools, not just for display or taxes.

Avian influenza spreads via infected birds and contaminated equipment; strict biosecurity prevents introduction. Feeding practices or allowing contact with wild birds increase risk.

Stopping bleeding with pressure and seeking veterinary care are immediate priorities. Dirty water, inaction or just feeding will not stop severe bleeding or prevent infection.

Internal parasites consume nutrients and cause poor growth in young animals. Shelter or sunlight are not direct causes, and grooming does not cause thinness.

Vaccines prepare the immune system to fight specific infections and reduce disease risk. They do not cure active disease instantly, replace hygiene, or give immediate production increases.

Trypanosomiasis is spread by the tsetse fly and causes wasting and anaemia in livestock. Mastitis, ringworm and hoof rot have different causes and are not transmitted by tsetse flies.

Good milking hygiene (cleaning, drying, teat dipping and milking infected animals last) reduces transmission of mastitis. Sharing dirty cloths or ignoring hygiene spreads infection.

Regular hoof trimming every 6–8 weeks keeps hooves healthy and prevents lameness. Trimming only once a year or never can cause serious hoof problems.

Heat stress causes animals to pant, breathe rapidly and seek shade or water. Weight gain or increased hair are not signs of heat stress.

Pasture rotation allows time for parasite larvae to die off and reduces re‑infection of grazing animals. It is a key part of parasite control, not done for taste or water reasons.

Anthrax often causes sudden death and may present with blood oozing from nostrils, mouth or other openings. Chronic cough or itchiness are not typical of anthrax.

Clean, fresh water in protected troughs prevents disease and ensures animal health. Stagnant or contaminated water spreads disease, and additives like sugar are not appropriate.
