Embodiment

[0184] Produced a sleeve throttle valve as the liquid feeding direction control unit. figure 1 The shown structure of the livestock fertilized egg retrieval device. A bovine balloon catheter is connected to this device, and fertilized eggs are recovered from the living bovine uterus, and the fertilized egg recovery method by intrauterine perfusion method (injecting the perfusate into the uterus in a natural drop method, which is different from the conventional method) Non-patent literature 1) compares working time and recovery accuracy. A senior veterinarian with more than 20 years of egg collection experience has implemented the prior method and the recovery method using the device of the present invention. The recovery method by the apparatus of the present invention was carried out by selecting the settings shown in the above-mentioned Tables 2 to 5 according to the size of the uterus of the bovine.

Abstract

The livestock fertilized egg recovery device (10) is provided with: a perfusate supply part; a first syringe (20) for sucking the perfusate from the perfusate supply part and injecting the perfusate into the livestock uterus; a balloon catheter, It is used to inject perfusate into the uterine horn and recover the perfusate together with the fertilized eggs; the second syringe (30) is used to recover the perfusate injected into the uterus of livestock and discharge the perfusate to the fertilized egg recovery part; fertilization an egg recovery part; a liquid feeding line (211, 212, 311, 312) for connecting them; and a liquid feeding direction control part (50) for controlling the feeding direction of the perfusate in the liquid feeding line, and The configuration includes a syringe pump control unit (40, 40') that controls pump operations of the two syringes.

Description

technical field [0001] The present invention relates to a domestic animal fertilized egg recovery device, a control method of the device, a program for executing the control method, and a method of recovering a domestic animal fertilized egg. Background technique [0002] Contrary to the shrinking of production bases in domestic livestock and dairy farming, the number of transplants of fertilized eggs of Kazuo Kuroge (Kuroge Wagyu) with dairy cows as borrowers has been increasing in recent years in terms of increased income for producers. expand. [0003] On the other hand, according to Japan's Livestock Improvement and Growth Law and Veterinary Law, those who can collect fertilized eggs from the uterus of a bovine living body are limited to veterinarians who have passed the national examination. In addition, there are few veterinarians related to industrial animals, and among them, there is also a shortage of egg-collecting technicians for bovine fertilized eggs. Furtherm...
