Embodiment

[0184] Manufactured a device that uses a sleeve throttle valve as a liquid feeding direction control unit figure 1 The livestock fertilized egg recovery device of the structure shown. A balloon catheter for cattle is connected to this device to recover fertilized eggs from the uterus of living cattle. Compared with the conventional method of fertilized egg recovery method by intrauterine circulation perfusion method (injecting the perfusate into the uterus in a natural drop method, Non-Patent Document 1) compares the operating time and recovery accuracy. A senior veterinarian with more than 20 years of experience in egg collection implemented the conventional 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 cow.

Abstract

A livestock fertilized-egg recovery device (10) is provide with: a perfusate supply part; a first syringe (20) for suctioning a perfusate from the perfusate supply part and injecting the perfusate into the uterus of livestock; a balloon catheter for injecting the perfusate into a uterine horn and recovering the perfusate together with a fertilized egg; a second syringe (30) for recovering the perfusate injected into the uterus of livestock and discharging the perfusate into a fertilized-egg recovery part; said fertilized-egg recovery part; liquid delivery lines (211, 212, 311, 312) that respectively connect between the perfusate supply part, the first syringe, the balloon catheter, the second syringe, and the fertilized-egg recovery part; and a liquid delivery direction control part (50) for controlling the delivery direction of the perfusate within the liquid delivery lines, wherein the livestock fertilized-egg recovery device is also provided with syringe pump control parts (40, 40')for controlling the pumping action of the two syringes.

Description

technical field [0001] The present invention relates to a device for recovering fertilized eggs of domestic animals, a control method of the device, a program for executing the control method and a method for recovering fertilized eggs in the uterus of domestic animals. Background technique [0002] Contrary to the shrinkage of production bases of livestock and dairy farming in Japan, the number of fertilized eggs of Japanese Kuroge Wagyu (Kuroge Wagyu) transplanted with dairy cows as borrowers has been increasing in recent years in terms of increasing the income of producers. expand. [0003] On the other hand, according to the Livestock Improvement and Breeding Law and the Veterinary Law of Japan, those who can collect fertilized eggs from the uterus of living cattle are limited to veterinarians who have passed the national examination. In addition, there are few veterinarians who are related to industrial animals, and among them, there are not enough technicians for coll...
