The use of B-ultrasound machines for cattle breeding and pregnancy management has advantages such as non invasiveness, high accuracy, visual display, and strong repeatability. It can provide accurate pregnancy diagnosis and monitoring of follicular and corpus luteum development, thereby optimizing breeding management and improving breeding efficiency.

Pregnancy detection using B-ultrasound machine for cattle

When using a bovine ultrasound machine to measure bovine pregnancy and follicular corpus luteum development, the following points should be noted:

1. Familiar with the operation of the cattle ultrasound machine: Operators need to be familiar with the usage and operation process of the ultrasound machine to ensure accurate measurement and diagnosis. There are many parameters for the ultrasound machine used in cattle, which sometimes need to be adjusted according to the actual situation. However, if the parameters are not adjusted correctly, it will affect the clarity of the detection image and cause judgment errors.

2. Choose the appropriate probe: Select the appropriate B-ultrasound probe based on the size of the cow and the area to be measured to ensure the accuracy of the results. There are many types of B-ultrasound probes for cattle, including rectal linear array probes, convex array probes, backfat eye muscle probes, live egg collection probes, etc. Different probes have different functions and can be selected according to actual needs.

3. Maintain cleanliness and hygiene: Before conducting ultrasound examination, it is necessary to ensure the cleanliness and disinfection of the ultrasound probe used by cattle to reduce the risk of cross infection and contamination. If conditions permit, disposable gloves can be used to cover the probe, and it can be replaced after not being tested once.

4. Choose the appropriate time: The pregnancy examination of cattle should be conducted at a suitable time after the expected pregnancy period, usually around 30 days of pregnancy for B-ultrasound examination, and better machines can detect it at 25 or 26 days.

5. Observing follicular development: During the examination of follicular corpus luteum development, it is necessary to observe the size, quantity, and shape of follicles to determine whether they are developing normally.

6. Observing the morphology and function of the corpus luteum: In addition to measuring the development of cow follicles, it is also necessary to observe the morphology and function of the corpus luteum in cows. The corpus luteum should have clear boundaries and uniform texture, while producing sufficient hormones such as progesterone.

7. Pay attention to abnormal conditions: During the examination process, it is necessary to pay attention to whether the cow has abnormal conditions such as follicular dysplasia, corpus luteum degeneration, and luteal function abnormalities. These abnormalities may require further diagnosis and treatment.

8. Regular use of bovine B-ultrasound machine for re examination: If no pregnancy or abnormal conditions are found during the initial examination, regular re examination may be necessary to ensure the normal development of pregnancy and follicular corpus luteum.

The above are several points to note when using a bovine ultrasound machine to measure bovine pregnancy and follicular corpus luteum development. These precautions can help veterinarians accurately detect and monitor the pregnancy status of cattle, and promptly handle any abnormal situations.
