If, you are getting to worry about your bunny pregnancy test, then don’t panic! Because, here from this article, we will explores the journey of rabbit pregnancy testing, from traditional to modern advanced diagnostic tools, including ultrasound, hormonal testing, palpation, X-ray and radiography with ease.

The Bunny Test as Historical Perspective
The rabbit test is also known as the ‘Friedman Test’. It was a pregnancy test that used in the early to mid-20th century. This test enabled with injecting the female rabbit urine into a female bunny, and taking an examination the rabbit’s ovaries within 48 hours.
If the rabbit’s ovaries are showing some positive symptoms of follicular maturation that means the female was pregnant.
The rabbit test was developed in 1931 by Maurice Friedman and Maxwell Edward Lapham at the University of Pennsylvania. It was essentially identical to the AZ test that was used mice instead of rabbits, but replaced the mouse with a rabbit.
The rabbit test became a widely used bioassay (animal-based test) to test for pregnancy. The term “rabbit test” was firstly found at 1949. It was the origin of a common euphemism, “the rabbit died”, for a positive pregnancy test.
Advancements of Rabbit Pregnancy Diagnosis Methods
Here, we will spread the light on tradition to advance approaches to test and diagnosis of rabbit pregnancy; below show each one, you can read them:
Ultrasound
Ultrasound imaging has emerged as a highly effective and reliable technique for confirming pregnancy and monitoring fetal development. This non-invasive method is most helpful for providing the valuable information in the context about mother’s health and fetuses throughout the pregnancy.
Procedure for Rabbit Pregnancy Diagnosis with Ultrasound
The process of diagnosing rabbit pregnancy with ultrasound involves the following steps:
Preparation: Prepare the ultrasound machine and necessary equipment. Ensure that the doe is calm and restrained in a comfortable position for examination.
Ultrasonography: Apply ultrasound gel to the abdomen to facilitate sound wave transmission. Position the ultrasound probe on the doe’s abdomen and begin scanning the area of the reproductive tract.

Visualization of Reproductive Organs: Use the ultrasound probe to visualize the uterus, ovaries, and other reproductive structures. It also helps to show the assess the size, shape, and consistency of the uterus that looking for signs of pregnancy such as the presence of fluid-filled gestational sacs.
Detection of Fetal Structures: Identify the presence of fetal structures within the gestational sacs. You can look for characteristic features like as fetal membranes, fetal poles, and fetal heartbeats. Measure the size of the fetuses to estimate gestational age and assess fetal development.
Confirmation of Pregnancy: Based on the presence of fetal structures and other signs of pregnancy, confirm the diagnosis of pregnancy. Document your findings and discuss them with the breeder or owner.
Hormonal Testing
Hormonal testing is also a modern technique. By using of this test, can be easily diagnosis of bunny pregnancy that allows measuring the levels of hormones in the blood or urine of the doe. This is mostly going to use hormone for this objective that is generated by the ovaries in pregnancy time.
Testing Methods
Hormonal testing for rabbit pregnancy typically enables the measuring progesterone levels in blood serum or plasma samples. The following steps outline the process of hormonal testing for rabbit pregnancy:

Sample Collection: Collect a blood sample from the pregnant rabbit by using a syringe or venipuncture technique. You make ensure that this sample keep properly handling and stored to maintain its integrity.
Laboratory Analysis: Send the blood sample to a veterinary laboratory equipped to perform hormonal assays. The laboratory will analyse the sample to measure progesterone levels using specialized equipment and techniques.
Interpretation of Results: Interpret the results of the hormonal assay based on the progesterone levels detected in the blood sample. Elevated progesterone levels above baseline indicate pregnancy, while low or normal levels suggest non-pregnancy.
Palpation
Palpation is a traditional, yet most effective method for diagnosing pregnancy in your rabbits. But, this method must be implementing by experienced practitioners. In palpation, vet can feel the abdomen of the female bunny to identify the presence of fetuses. This technique is usually executed around 14-15 days after artificial insemination (AI).
Procedure of Palpation Testing
Palpation test is manually examination of abdomen of the rabbit to feel for developing fetuses. The following steps outline the procedure for rabbit pregnancy diagnosis with palpation:
Restraint: Securely restrain the rabbit in a calm and comfortable position to minimize stress and facilitate examination.
Abdominal Examination: Gently palpate the abdomen of the rabbit using your fingers. Apply gentle pressure to different areas of the abdomen to feel for the presence of developing fetuses.
Identification of Fetal Structures: Feel for characteristic features such as fetal membranes, fetal poles, and fetal movements. Identify the number and size of the fetuses to assess pregnancy status.
X-Ray and Radiography
X-ray and radiography are most valuable diagnostic tools to confirm pregnancy in rabbits. This method is less commonly used as compared to ultrasound and hormonal testing. But, it can also provide the closely estimation of litter size and fetal development in later pregnancy’s stages.

Radiography with X-rays gets consistency in measurements within each exam, and allows for monitoring of fetal growth in between ultrasound exams. Later in gestation, longitudinal spine lengths and cranial diameter of fetuses can be measured to estimate both fetal number and gestational stage.
Procedure of X-Ray and Radiography
The process of rabbit pregnancy diagnosis with X-ray and radiography involves the following steps:
Preparation: Prepare the rabbit for X-ray or radiographic examination by restraining her in a suitable position. Ensure that the rabbit is calm and comfortable to minimize stress during the procedure.
Radiographic Imaging: Position the X-ray machine or radiographic equipment to capture images of the rabbit’s abdomen. Adjust the proper settings for getting optimizes image quality and minimize radiation exposure.
Image Acquisition: Capture radiographic images of the rabbit’s abdomen, focusing on the reproductive organs and pelvic region. Capture the multiple views, like as lateral and ventrodorsal views, to get comprehensive images of the uterus and developing fetuses.
Interpretation of Results: Interpret the radiographic images to assess pregnancy status and fetal development. Look for signs of pregnancy, such as the presence of fetal skeletons, fetal number, and fetal positioning within the uterus.
FAQs (Frequently Asked Questions)
What is The Rabbits Pregnancy Tests?
Rabbit pregnancy tests confirm you either your rabbit is pregnant or not. It enables various methods like as ultrasound imaging, hormonal assays measuring progesterone levels, palpation, and X-ray/radiography. By using these techniques, you can confirm gestation, assess fetal development, and plan for the care of pregnant does and their offspring.
Why did Rabbit Died in Pregnancy Tests?
The rabbit may die in pregnancy tests, because the presence of human chorionic gonadotropin (hCG) in a pregnant female’s urine that would cause the rabbit’s ovaries to enlarge. To confirm pregnancy; dissected to examine its ovaries for signs of enlargement, regardless of the test result.
How did Rabbit Pregnancy Test Work?
Rabbit pregnancy tests work by various methods such as ultrasound imaging to visualize fetal structures, hormonal assays measuring progesterone levels indicative of pregnancy, palpation to feel for developing fetuses, and X-ray/radiography to assess fetal skeletons. These techniques provide accurate diagnosis and guide reproductive management decisions.
When is The Best Time to Test a Rabbit for Pregnancy?
Testing can occur as early as 10 to 14 days after mating, but depending on the using method. Ultrasound and hormonal assays are effective for early detection, but palpation and X-ray/radiography are more suitable for later stages.
Can Rabbits have False-Positive or False-Negative Pregnancy Test Results?
Yes! False positives or negatives can be possible, especially with less accurate methods or if testing is performed too early or late in gestation.
How Long is a Rabbit’s Gestation Period?
Rabbit gestation lasts approximately 28 to 31 days, after which the doe gives birth to a litter of kits.
