EVO Cow Live Egg Collection Instrument has a set of live egg collection application dedicated to cows. OPU live egg collection of cattle requires the use of ultrasound live egg collection instrument to guide, through ultrasonic images to observe the position and development of the cow follicle, guide the egg collection needle to collect eggs.

The procedure for collecting eggs from live cattle is as follows:

1. Bovine follicles were observed with EVO.

2. The 18-gauge disposable hypodermic needle was connected to the 50 ml conical tube through the teflon tube for hair follicle puncture.

3, use the vacuum suction pump to apply negative pressure, suction vacuum adjustment to the flow rate of 15 ml of water per minute (the specific value can be adjusted according to different brands of negative pressure pump).

4. Place the collection tube in a 39℃ constant temperature tank (some vacuum pumps come with a constant temperature tank).

5. Cows receive epidural anesthesia to prevent them from straining during surgery.

6. After the rectum is emptied and the vulva and perineum areas are cleaned, the probe of the ovimeter is inserted into yd.

7. The ovaries are operated rectally and placed in front of the probe to obtain a clear image on the screen of the egg collection instrument.

8, before, during and after OPU, the needle and the teflon tube should be thoroughly washed to prevent blood clotting or oocytes sticking to the teflon tube.

9. Immediately after OPU, oocytes were searched using a stereomicroscope, washed, and transferred to mature media.
