Tips for Successfully Breeding Your Mice Marcel Perret-Gentil, DVM, MS University Veterinarian & Director Laboratory Animal Resources Center The University of Texas at San Antoni Female mice in estrus will be receptive to mating. By picking females in estrus, you can maximize the breeding of your mice, or obtain multiple females mated at the same time. You should expect two-thirds to three-quarters of mice in estrus to mate, on average. Females in estrus have swelling of the lip of the vulva closest to the anus Mate mice when they are sexually mature (6 to 8 weeks old). We recommend that transgenic founders or chimeras be mated to C57BL/6 mice. After 6 generations of mating to C57BL/6, more than 99% of the genetic background will be C57BL/6 If you are planning to breed your mice, you should provide nesting material (tissue paper works well) in one corner of the cage. Females can have up to 15 litters a year and can become pregnant within 24 hours after giving birth. The average gestation time for mice is 19 to 21 days. Baby mice are called pups and are born deaf and blind Breeding your mice is not a decision to make lightly and you absolutely must consider what you will do with any babies that result. Most pet stores have established suppliers already. You should also carefully consider the temperament and health of the mice you are breeding

There are numerous reasons why this is a good idea: Purchasing frozen rodents can become expensive Pet stores do not always have rodents in stoc A minimum of two to four breeding pairs are recommended for most strains; additional pairs are suggested for strains challenging to breed, or to expedite colony expansion. Alternatively, it may be more cost-effective to have JAX provide study-ready mice for your experiments (see JAX ® Breeding and Phenotyping Services) Breed the mice. Breeders often place one male in a cage with five females, as a male can impregnate many females in succession. Males should not be placed in the same enclosures to prevent fights, injury and stress among the territorial male mice. Mice can be bred at the age of six weeks and can typically be bred for a year

Mice have short gestation times and large litters. Therefore, cages may become overcrowded quickly if the individual responsible for managing the breeding colony and separating animals at the proper times does not do so in a timely fashion. When overcrowding of cages happens, the animals become uncomfortable and stressed If you decide to breed mice for any reason, you'll want to provide them with safe, comfortable living conditions, and treat them humanely. Beyond that, breeding mice is mostly a matter of making sure that the mice are grouped together in the right way. Method 1 Prepping a Home for Your Mice Download Articl A Breeding mice can be fun, but is often frustrating. Everyone has a method that works best for them. This is what seems to work well for me.

2. Breeding Schemes - MICE a. Monogamous pair (1 male, 1 female) in a standard housing cage. Male is not necessarily separated when the female becomes pregnant or delivers the pups. Litters are born approximately 21 days apart. The three-week-old litter must be weaned prior to the birth of the new litter. b Hemizygous mice can be included in breeding strategies identical to those used for breeding heterozygous mice. In this case, your parental mouse should be hemizygous at the appropriate allele. When crossed to a mouse that is homozygous for a different mutation, the F1 offspring will be either hemizygous or null at one locus (e.g. Cre) and.

AN INTRODUCTION TO BREEDING. When breeding fancy mice, the usual foundation stock is a trio (or two) of your chosen variety. This comprises a buck and two does. These are mated together when they reach a suitable age (usually around 12 weeks, but this can vary with some varieties doing better if slightly younger) Breeding pair (1 male:1 female): The male, female and the resulting litter of pups may be kept together in a Group I cage (static or ventilated) continuously until the pups are weaned. Breeding trio (1 male: 2 females): Mice should be kept in a Group II microisolator or large ventilated cage (Allentown) Fancy Mice Different colors of Fancy Mice.

  2. In general, mouse pups should be weaned from their mother between 21-26 days of age. At this time, male and female pups must be separated into same-sex groups to avoid accidental breeding when mice reach puberty at 6-8 weeks of age. If litters are not weaned promptly, the cages will become overcrowded
  3. Mouse breeding record system: The Breeder Card. Mice can be paired at 6-8 weeks of age. When animals are paired for the first time, create a breeder card that includes a number unique to the pairing of these two animals. Write the unique number in the upper right-hand corner of the breeder card. This number is in sequential counting order.
  4. Breeding mice for snakes is a good way to give your pets the most nutritious meals possible. Essentially, you need to set up the cage with male and female mice in them, watch for signs of pregnancy, remove females from the area when pregnant, and wean the young 3-4 weeks after birth
  5. Successful breeding of the laboratory mouse (Mus musculus) is critical to the establishment and maintenance of a productive animal colony. Additionally, mouse embryos are frequently studied to answer questions about developmental processes. A wide variety of genetic tools now exist for regulating gene expression during mouse embryonic and.
  6. Genetically modified mice can be generated using a variety of methods.

First, the transgene inserts at random into the genome. Breeding the transgene to homozygosity results in mice that carry this insertion on both chromosomes, increasing the probability that the insertion will result. A typical female mouse can birth between five and 10 litters per year. She can mate immediately after giving birth, meaning mice can birth a second litter in as little as 25 days after the first. This quick maturation process gives mice immense breeding capabilities. Living indoors enhances these capabilities, since they can then breed all year. Breeding can occur throughout the year and thus if a pair of mice enters your home they can produce hundreds of mice in the short period of time. Mice that live outdoors can live up to 12 months on average. Mice that find a cozy indoor dwelling can live between 2 to 3 years. Unfortunately, mice are well-known breeding machines

There are many mice breeders--we have mouseries--that keep very good pedigrees of their mice and do not and will not inbreed. Lots of information about breeding mice can be found at thefunmouse.com Eight months later, roughly the length of a breeding season, the original pair of mice can generate about 500 rodents. But this is only from one pair of mice. When looking at just four pairs, for. Bridget H/CC-BY 2.0. Mice are fertile animals because female mice come into heat every four to five days. Their reproductive rate depends upon how often males and females actually mate. An average female mouse has 30 to 35 babies per year. A mouse's pregnancy lasts between 19 and 21 days. However, if the mother is still nursing another litter. We housed breeding trios of two types of nude mice, with or without nesting material for 6 months (i.e. a 2 × 2 factorial design).
