Is it possible to just have one mice?
No home ever has just one mouse and don’t be fooled into thinking otherwise. Mice can breed year-round with one female able to produce five to 10 litters per year. With an average of six to eight babies per litter, a family of six mice can multiply into 60 over the course of three months.
Does one mouse mean more mice?
Though it may seem silly, there could be something to this impulse. One mouse can be something frightening, indeed, because if you see one mouse, there are more.

But the best clue to know when all the mice are gone is by not finding any new mouse droppings or any other signs of mice activity.
What makes a giant mouse a transgenic mouse?
The giant mouse developed from a fertilized egg transformed with a recombinant DNA molecule containing the structural gene for human growth hormone and a strong mouse gene promoter. The levels of growth hormone in the serum of some of the transgenic mice were several hundred times higher than in control mice.
How many strains of inbred mice are there?
There are over 450 different strains of inbred research mice, and these strains have recently been organized into a chart. The deer mouse (Peromyscus maniculatus)lives in the Americas and is closely related to the white-footed mouse. Those interested in the mouse reproductive cycle should also look at the mouse estrous cycle.
How often do you have to breed male mice?

When to replace a transgenic founder in mouse breeding?
If no litters are produced after one month you should replace the mice that you are mating with your founder. It is possible that the transgenic founder may be infertile due to consequences of transgene expression or unknown reasons.
What did the NIH study on mice do?
Researchers from NIH’s National Institute on Aging (NIA), led by Dr. Rafael de Cabo, wanted to better understand if the type of food eaten, and when it is eaten, alters how calorie restriction affects the body. They divided almost 300 male mice into two diet groups.
Which is better for mice, CR or MF?
Compared with mice in the AL groups, mice in the MF groups lived about 11% longer, even though their total food intake and body weights were similar. Mice in the CR group lived about 28% longer. Mice in the CR and MF groups also developed disease later than mice in the AL groups.
What’s the difference between Al and CR mice?
A calorie restricted (CR) group received 30% less food than the AL group, placed into their cage once a day at the same time. A meal fed, or MF, group was given the same amount of food as the AL mice on average, but were fed only once a day.
What kind of diet is best for male mice?
Researchers from NIH’s National Institute on Aging (NIA), led by Dr. Rafael de Cabo, wanted to better understand if the type of food eaten, and when it is eaten, alters how calorie restriction affects the body. They divided almost 300 male mice into two diet groups. One group was given a diet low in sugar and based more on whole foods.
