Rectal examination of cows for pregnancy: a technique for diagnosing pregnancy
Rectal examination of adult cows for pregnancy allows you to determine the presence of pregnancy and even determine the term. After all, a cow in a position needs special care, care and conditions of detention. In addition, such diagnostics can help identify pathologies of fetal development in the early stages, as well as detect diseases in the pelvic organs of cattle.
Preparation and diagnostic technique
The study of a cow has the right to conduct only a specialist - a veterinarian or livestock specialist. He is exceptionally able to correctly interpret the results. For the procedure, you will need to prepare a cow in advance, and the doctor will follow all safety measures.
The veterinarian should cut the nails on both hands short, level them with a file, wash their hands with soap and warm water, treat all existing wounds and microdamages with iodine or another antiseptic. Wear high rubber or polyethylene disposable gloves up to the shoulder, as well as an oversleeve and a waterproof apron. Lubricate your palm with Vaseline for better glide. In addition, you will need the help of a partner who will fix the cow and hold the tail.
Before this, the cow is kept on a semi-starved diet for a day or even a study is carried out in the early morning when the intestines are emptied.
Features of the study of the reproductive system
Rectaling a cow is extremely careful, because there is a high risk of damaging the intestinal mucosa and affecting the genitals. Yes, and most become infected in the event of a rupture of the glove. Diagnostics of the reproductive system involves examining the uterus and ovaries for pathologies and monitoring the course of pregnancy by months.
With infertility and gestation, the uterus is located in the pelvic cavity and is easily palpable when the hand is moved to the side along the bottom, like a dense elastic area. The absence of this sensation indicates pathologies or late pregnancy.
After the doctor proceeds to the examination of the ovaries. To find them, you need to put your hand on the site of separation of the uterine horns, fingers "dangling" between and shifting to the side until they come across an ovoid dense object. It is being studied for cysts and follicles.
What situations you need to know before the examination:
- Incorrect position of the uterus indicates endometritis or advanced age of the animal.
- Increased tone is a sign of pregnancy.
- The uterus with the fetus is strongly stretched, and the consistency of its walls is not uniform.
- The intercorneal cavity smoothes out by the third month of pregnancy.
- The pulse of the uterine arteries increases as labor approaches.
Rectal diagnosis of cattle with the help of hands has proven itself well, but today it does not provide accurate information about all diseases and abnormalities. For reliability, it is recommended to use ultrasound equipment in combination with a manual method.
