Inotiv uses well-established techniques to successfully produce time mated rats, mice, hamsters, and rabbits. We use an impedance meter for determining the stage of estrus in rats prior to breeding. Time mated rats and mice are determined by observation of a vaginal plug. Plug date for rodents is considered to be day zero (0) of gestation.
Due to the natural variation in the length of gestation, the exact day of parturition cannot be guaranteed. In addition, Inotiv cannot guarantee the minimum number of offspring per litter.
Inotiv will not ship animals which are in the last stage of gestation, as they may deliver their litter prematurely while in transit, and depending on the circumstances involved, requests for credit or replacement of these animals may be declined at our sole discretion.
If problems regarding gestational age or pregnancy are encountered, customers should immediately contact Inotiv’s customer service department and provide detailed information regarding the animals involved.
|Expected Pregnancy Rate|
|Stock or Strain||Timed mated <13 days gestation (at shipping)||Timed mated ≥ 13 days gestation and over (at shipping)||Untimed pregnant ≥ 13 days gestation (at shipping)|
* Plug guarantee only; no guaranteed pregnancy. Plug date = Day 0.
** Untimed pregnant rodents will be selected from our breeding colonies on the basis of palpation or visual conﬁrmation. A variation of three to four days gestation can be expected. Inotiv is not responsible for actual gestation and/or exact day of littering for untimed pregnant rodents.
Through and including February 28, 2023, in order to avoid charges, cancellations for timed mated animals must be received one week prior to mating date.
Effective March 1, 2023, and thereafter, to avoid charges, cancellations for time mated rats, mice and hamsters must still be received one week prior to mating date, however, cancelled orders for time mated rabbits will be charged at full price regardless of the amount of notice supplied.
