On Animal Husbandry
Since all animal maintenance and subsequent breeding of transgenic mouse lines will be carried by the individual investigator, a knowledge of basic mouse husbandry is essential. Here are some basic guidelines and suggestions.
- Mice are born 19-20 days after vaginal plug detection (i.e., successful mating).
- If neonates do not show white stomach (milk) 24 hours after birth, suspect a bad mother; foster mother (lactating female) should be used or pups will die.
- Litters should be weaned at 3 weeks after birth.
- Sexual maturity of females: approximately 6 weeks; that of males; approximately 8 weeks. Maturing males should be housed individually as they tend to become aggressive with one another.
- Watch for water bottle leaks; neglected wet cages can result in the death of animals.
- For animal health problems in your colony or more specialized information, please contact the attending veterinarian of the University Laboratory Animal Resources.
