House mice were live-trapped in the orchards within the site of AL- Farabi University collage from Late of December 2017 till The end of March 2018. It was found that there was active normal reproduction during the winter months December, January, February and March. The pregnancy rates during these months ranging between 41 and 81 % with Litter size ranging between 4 and 8 pups. The numbers of embryos ( M.±  S.E. ) for the months of the study were 6± 0.38, 5 ± 0.33, 4.81 ±  0.39  and 4.88 ±  0.33 respectively.
