To provide means for enabling performing the collection of a fertilized egg from a living body uterus of livestock, particularly cows easily and in a short time with the same accuracy as a skilled technician.SOLUTION: A livestock fertilized egg collecting device of the present invention comprises: two syringes； a liquid feed line for connecting a perfusate supply unit, a first syringe, a balloon catheter, a second syringe, and a fertilized egg collection unit； a liquid feed direction control unit for controlling the liquid feed direction of the perfusate in the liquid feed line； and a syringe pump control unit for controlling the pump operation of the two syringes. According to this device, the two syringes are operated simultaneously by interlocking the syringe pump control unit with the liquid feed direction control unit, and the taking in-and-out of the perfusate can be carried out at high speed, and therefore the fertilized egg collection working hours are greatly shortened, and the fertilized egg in the living body uterus can be collected quickly and easily with the same accuracy as a skilled technician.SELECTED DRAWING: Figure 1【課題】家畜、特に牛の生体子宮からの受精卵の回収を、熟練技術者と変わらない精度で簡易かつ短時間で実施することを可能にする手段を提供すること。【解決手段】本発明の家畜受精卵回収装置は、２つのシリンジと、灌流液供給部－第１シリンジ－バルーンカテーテル－第２シリンジ－受精卵回収部を接続する送液ラインと、送液ライン内の灌流液の送液方向を制御する送液方向制御部と、２つのシリンジのポンプ動作を制御するシリンジポンプ制御部とを具備する。該装置によれば、シリンジポンプ制御部と送液方向制御部の連動により２つのシリンジを同時に動作させ、灌流液の出し入れを高速で実施できるので、受精卵回収作業時間が大幅に短縮され、熟練技術者と変わらない精度で簡易迅速に生体子宮内の受精卵を回収できる。【選択図】図１
