What measures to take if the mice are having difficulty breeding?

Gene Summary

Gene Name

Model Description

<p style="text-align: justify;">Check for the following problems when the number of offspring is decreased in the breeding process or when no offspring is born: <p style="text-align: justify;"><br> <p style="text-align: justify;"><strong>The breeding environment is too noisy: </strong>during the breeding and feeding of mice, noise should be minimized to ensure that the mice live in a quiet environment. <p style="text-align: justify;"><br> <p style="text-align: justify;"><strong>Pregnant mice are stimulated by external stress:</strong> The operation and environmental changes incurred to pregnant mice should be minimized. When pregnant mice and lactating mice are stimulated by external stress, they may eat or abandon their cubs. <p style="text-align: justify;"><br> <p style="text-align: justify;"><strong>The mating time between male and female mice is too short:</strong> Ensure an appropriate length of mating time between male and female mice to increase the chance of mating. In addition, do not remove mating male mice from the cage when pregnant mice are in labor, and do not put the male mice back into the breeding cage before the offspring mice are weaned. <p style="text-align: justify;"><strong>Increase the darkness of the environment: </strong>avoid unnecessary light in the night rhythm because it can affect the circadian rhythm of the mice. <p style="text-align: justify;"><br> <p style="text-align: justify;"><strong>The mice are unable to build nests:</strong> Provide soft fiber materials, such as cotton wool, paper towels or cork flocculus, in cages to facilitate the establishment of a safe and comfortable environment for labor, thus increasing the number of litters. <br> <p style="text-align: justify;"><strong>Nutritional deficiency: </strong>If the lipid component is too high or too low in mouse diet, or if the protein intake is insufficient or excessive, the reproduction of mice will be affected.In addition, the source of tocopherol, such as seeds and nuts, can be provided as appropriate. <br>
