Why use a B-ultrasound machine to test the pregnancy of cows? Breeding personnel want to identify pregnant ewes in order to remove them from the breeding herd. Pregnancy testing using a B-ultrasound machine can obtain a large amount of useful data:

1. B-ultrasound detection can determine the gestational age of bovine fetuses.

2. We can classify cows according to their gestational age to keep the calving grounds clean.

3. We can monitor the performance of bulls, feeding plans, and potential disease issues in the herd.

4. The male and female parents of the fetus can be determined at certain stages of pregnancy, and this information is valuable for breeding and production.

When can I use a cow ultrasound machine to detect pregnancy?

Cattle breeders need to have a basic understanding of bovine reproductive ultrasound so that they can collaborate with veterinarians to achieve optimal results. For example, depending on the stage of pregnancy, separating heifers bred by artificial insemination from heifers bred by cleaning bulls may be a relatively easy task or an impossible task. For example, most veterinarians who have received ultrasound training can accurately distinguish 43 day old artificially fertilized heifers from 100 day old heifers bred by bulls undergoing cleaning with 50% accuracy. If the pregnancy test is postponed to 100 days of pregnancy in AI heifers and the "interval" is 7 days, errors in separating these groups may occur. Due to the significant impact of genetics, nutrition, fetal gender, abdominal position, and other factors on the ability to accurately determine fetal age at this stage, it is difficult to accurately distinguish between 100 day pregnancy and 93 day pregnancy.

As the fetus develops in the cow's body, the ability to accurately age the fetus will weaken. This makes sense because there are many factors that can affect the size of the fetus and the veterinarian's ability to measure certain parts of the fetus in the cow's large abdominal cavity.

Fetal aging courses can help people develop skills and better understand the processes involved in fetal aging. There are quite a few learning resources available online. By gaining a better understanding of fetal gestational age and the optimal timing for testing during pregnancy, beef and breeding producers can collaborate with veterinarians to obtain valuable data that can be used to improve their cattle herds.
