Study Notes

Animal Housing and Welfare

  • If group housing is not possible, animals should be provided visual, auditory, and/or olfactory contact with others of the same species.
  • Animals should be provided opportunities to play and exercise.

Housing for Large Animals

  • Large animals require physically demanding and labor-intensive housing.
  • Equipment and procedures should be regularly evaluated and refined to maximize personnel safety and minimize ergonomic injuries.

Specialized Housing Systems

  • Metabolism cages are used in studies where urine or feces collection is required.
  • Exercise cages are used in studies involving nutrition or exercise and provide a form of enrichment.
  • Transport, transfer, and shipping cages are used to relocate animals temporarily.
  • Disposable MI shoebox cages are used in some settings.

Environmental Enrichment

  • Environmental enrichment is essential to meet the psychological needs of all species.
  • Plastic materials used in caging include polysulphone, polycarbonate, polystyrene, and polypropylene, each with its advantages and disadvantages.

Caging Materials

  • Metals used in caging include stainless steel, aluminum, and galvanized metal, each with its advantages and disadvantages.

Rodent Housing

  • Shoebox-style cages are commonly used to house murine rodents.
  • Microisolation (MI) cages are refinements of shoebox cages that utilize a plastic top with an integral filter to prevent the exchange of allergens and microorganisms.
  • Individually ventilated cages (IVCs) are refinements of static microisolation caging systems that provide containment and microbiological protection for rodents.

Nonhuman Primate Housing

  • Nonhuman primates should be socially housed whenever possible in caging configurations that allow flexibility in enclosure size and connection of adjacent enclosures.
  • Housing should include perches, climbing structures, and other enrichment devices to promote psychological well-being.

Large Animal Housing

  • Large animal enclosures include freestanding, mobile cages, and permanent installations within a room.
  • Flooring and bedding materials should be selected based on species and should provide good footing without causing skin abrasions.

Ventilated Systems

  • Ventilated caging systems are popular due to their ability to improve the environment for animals and decrease human allergen exposure.
  • Automated monitoring systems with alarms can detect ventilation failures and alert staff to relocate animals.

Other Small Mammals

  • Front-opening, drawer-type cages are used to house rabbits, guinea pigs, chinchillas, and ferrets.
  • Social animals should be group housed whenever possible, and social species should be housed in compatible groups.

Food and Bedding Materials

  • Food and bedding materials should be obtained from vendors who ensure the quality of their products.
  • Food should be palatable, uncontaminated, and nutritionally adequate, and should be stored in clean areas to minimize disease and parasites.

Watering Equipment

  • Water is an essential nutrient, and water quality should be standardized to eliminate contaminants.
  • Watering equipment includes bottles with sipper tubes or water pouches, and automated watering systems that reduce labor intensity and ergonomic issues.

Bedding Dispenser and Facility Equipment

  • Bedding material should be selected based on species, housing method, and experimental conditions.
  • Facility equipment, including specialized equipment, is required to provide high-quality care and sanitation.

Common Facility Classifications

  • Biohazard facilities require specialized equipment and decontamination methods to handle infectious materials.

Housing Regulations

  • The Animal Welfare Act (APHIS, 2017), the Guide, and the Ag Guide (FASS, 2010) provide specific minimum space recommendations for group and individually housed animals.
  • Primary enclosure size depends on species, body weight, exercise requirements, and enrichment needs.

Learn about the design and maintenance of automated drinking systems for animals, including one-way valves, fresh water flushing, sanitation procedures, and monitoring requirements.
