Basic Laboratory Animal Management: 4 things |
|
Definition
Housing: cages must be large enough for normal behavior; free of sharp surfaces; provide eating and breeding space; easily cleaned and well ventilated
b) Physical Comfort: dry, clean, free of excessive noise; temperatures between 65 to 84 F; adequate lighting; ventilation at 10 complete air changes per hour
c) Health Care: cage cleaning 1 to 3 times per week;daily observation for health problems
d) Identification: individual identification - mice (ear punch, toe clip coat color); rats (ear punch); rabbits (ear tag); hamsters (ear punch, ear tag) |

Mouse (Scientific Name) Secretive, burrowing, nocturnal, territorial animals Housing? Name 4 Puberty? Estrous Cycle? Estrus Period? Gestation? Weaning? Litter Size? |
|
Definition
The Mouse (Mus musculus)
1) secretive, burrowing, nocturnal, territorial animals
2) Housing for lab work:
Conventional - no extraordinary measures
Specific Pathogen Free (SPF) - free of specific disease casing microbes
Gnotobiotic - very, very clean; raised aseptically with specific microbe added back to the colony of mice
Axenic - completely sterile environment, like gnotobiotic but with no microbes added back
3) Basic Biology: puberty: 50 -60 days; estrous cycle: 4-5 days; estrus period: 20-24 hours; gestation: 21 days; weaning: 21 day old pups; litter size: average - 10 to 12 pups

Mice Digestive System? Average Birth Weight? Male and Female adult weights? |
|
Definition
Digestive system: simple stomached omnivores
Average birth weight: .75 to 2 grams; male adult wt - 25 to 40 g; female adult weight - 20 to 40 g
Mice are very prolific: 1 pair of mice, left on their own, would create 1 million descendants in 425 days |

Rats are: Three things Basic housing? Basic biology? Puberty? Estrous cycle? Estrus period? gestation? Weaning? Litter size? |
|
Definition
easily & inexpensively maintained, usually disease resistant, well suited as a research model
2) Basic Housing - similar to mice, but not generally reared in gnotobiotic or axenic environments (require approx 40 sq inches space per 300 g rat)
3) Basic Biology: puberty: 65 - 100 days of age; estrous cycle: 4-5 days; estrus period: 6-12 hours; gestation: 21-23 days; weaning: 21 day old pups; litter size 6 - 12 pups (rats are prolific, but not on the same scale as mice)

Term
Rats Digestive System? Birth Weight? Male adult? Female adult weight? Rats are clean, quiet, and easily trained. |
|
Definition
Digestive system: simple stomached omnivores
Average birth weight: 5-6 grams; male adult wt: 450 - 520 g; female adult wt: 250 - 300 g
4) As pets; rats are clean, quiet & easily trained; communal living is possible with little fighting (unlike male mice which will fight often) |

The Hamster Common for ____ and ____ known for (3 things) They are (3 things) |
|
Definition
| 1) common lab animal & pet; known for cheek pouches and ease of domestication and ease of escaping (all domestic hamsters are descendants of 1 male and 2 females captured in 1930); nocturnal, burrowing animal; pseudohibernation |

The Hamster Basic Biology: Puberty in Males? Females? Estrous Cycle? Estrus Period? Gestation? Weaning? Litter Size? |
|
Definition
2) Basic Biology: puberty: males - 10 to 14 weeks, females - 6 to 10 weeks; estrous cycle: 4 days; estrus period: 4-23 hours (average 20); gestation: 15-16 days; weaning: 20-25 day old pups; litter size: 5 to 9 pups

The Hamster Average Birth Weight? Adult Weight in Males? Females? Which are larger? What should you do? Whats common with litters? Digestive System? |
|
Definition
Average birth weight: 2 g; male adult wt: 85 to 130 g; female adult wt: 95 to 150 g
NOTE: Unlike most specie of animal, female hamsters are generally larger than males; females also 'bully' males when they are not in heat and are capable of killing males; males should be removed from cages shortly after copulation; cannibalism of litters is also common
Digestive system: simple stomached omnivore |

The Rabbit (Oryctolagus cuniculus) Common for 4 things Breeds! (Name 6) |
|
Definition
1) common lab animal, pet, food source and pelts; Breeds: Giant Chinchilla, Flemish Giant (large breeds, 14-16 lbs); California, New Zealand (med, 4-14 lbs); Dutch, Polish (small, 2-4 lbs)

Term
The Rabbit (Oryctolagus cuniculus) Gestation? Weaning? Litter Size? Breed all year long but most litters will be produced from when to when?
|
|
Definition
gestation: 29-35 days; weaning: 4-6 wk old kits; litter size: 4-10 kits; can breed all year long, but most litters will be produced from early spring to late fall (depending upon latitude)

Term
| Rabbits ovulate when? Average birth weight? Omnivore, Herbivore, or Carnivore? Digestive System? Like what animal? Rabbits practice _______ |
|
Definition
Rabbits are induced ovulators - ovulate from the physical stimulation of the cervix by the male
Average birth wt: 30-80 g;
Digestive system: strict herbivores, fermentative hind-gut, like horses; rabbits practice coprophagy - in particular the ingestion of 'night-stool' directly from the anus |

Term
The Rabbit Basic Biology: Puberty in males? Females? No Estrous Cycle but have a ( _ to _ day period for receptivity and a _ to _ day period of non-receptivity) |
|
Definition
| Basic Biology: puberty: males - 6 to 10 months, females - 4 to 9 months; NO ESTROUS CYCLE but do have a 7-10 day period in which they are receptive to the male and a 1 to 2 day period of non-receptivity; |
