Overview of Small Animal Science

ObjectivesDefine the terms ‘Zoology’ and ‘Zoonosis’Sort different small animal species into their

designated taxonomic groupsIdentify the different small animal categories

that are used for this classAnalyze the different animal taxonomy groups

The study of animals is called zoology ...Animal scientists are called zoologists.Animals are classified into different groups for

study.

Animals are generally classified like this ... KingdomPhylumClassOrderFamilyGenusSpecies

This classification system is a taxonomy ...

Taxonomy is the branch of science concerned with the classification of organisms.

The animal must meet all the requirements starting from the highest category -- the KINGDOM

Down to the lowest category to fit into a particular group -- in this case, the SPECIE

All animals in these lessons fit in 5 categories:Osteichthyes Amphibia or amphibians Reptilia or reptilesAves/Aviary Mammalia or mammals

(bony fishes)(frogs and toads)

(snakes and lizards)(birds)

(dogs, cats and rabbits)

The study of fish ...

Is called icthyologySubphylum: PiscesLive in waterPermanent gills for

breathing, fins and body covered with scales

Cold-blooded

The study of amphibians ...

Is called herpetologyCold-blooded

vertebratesYoung live in water,

whileadults live on land.

Animal welfare vs. Animal Rights

Animal Welfare: Animals should be

treated humanely. Animals can be used for

human purposes.

Animal Rights: Animals have the same

rights as humans. Animals should not be

used for food, clothing, entertainment or research.

Ethically wrong for animals to be used for human purposes.

Animal Welfare Act of 1966Regulates dealers and laboratoriesMandates standards for housing, handling,

treatment, feeding and shelter of laboratory animals

Research institutions must have a review committee

Procedures for euthanasia

Risks in working with animals ...Zoonosis (disease that can be transmitted

from animal to human)• Internal parasites• Toxoplasmosis• Rabies• Bacteria• Ringworm

Overview of the industry:Companion animal industry is big and growing

biggerCats and dogs have largest shareConsumers spend a lot on their pets:• Pet food (about 47% of spending)• Health services• Toys, collars, leashes, etc.• Grooming, boarding, training, breeding, etc.
