title: [Estrous cycle of the Arctic lemming (Dicrostonyx torquatus Pall.) maintained and breeding under laboratory conditions].
abstract: Reproductive functions and life at laboratory conditions were studied in the lemming. Standard cage-terrariums with a wheel for motion and a plate for drinking are quite convenient. The main ration includes: hay, oats with some carrot added, some apples two--three times a week, sunflower seeds. The animals feel well and reproduce at +8 degrees and +20 degrees in well ventilated rooms. The estrous cycle in lemming females studied by microscopy of vaginal smears is not regular. Only two stages are definitely seen: diestrus and estrus. Intermediate stages--proestrus and metaestrus--can be identified by a successive studies of vaginal smears of the same animal.
