As an embryological tool, the rabbit (Taxon- Oryctolagus cuniculus) along with human was a species which show birth defects with thalidomide (teratogenic effects not detected with prior testing on other species).
These animals are herbivores with a very high breeding rate and number of offspring produced. Rabbit ovulation is induced by mating allowing an accurate staging of embryonic age and pregnancy.

- The Oryctolagus cuniculus haploid genome is estimated to be 3500 Mb.
- The diploid genome is organized in 21 pairs of autosomes and two sex chromosomes.
- Rabbit gene sequences are more similar to human sequences than rodent ones.

Rabbit Reproductive Cycle
|Early growth of the rabbit morula and blastocyst.|
Early development data from an in vitro development study.
| Fertilization - penetration of most ova during the first hour after ovulation.
Timeline of rabbit gonad development.
Day post coïtum (dpc)
- 9 - first germ cells are detected in both sexes.
- 14 - gonad macroscopically evident, the mesonephros and gonads are still connected and interactions between tissues are probable.
- 16 - most germ cells already entered the genital ridges (crests).
- 16 to 25 - regression of the mesonephros.
- 23 - gonadal and mesonephric tissues are separated by connective tissue. Thought to prevent the migration of cells and other substances.
Days post partum (dpp)
- birth - XX gonads first signs of meiosis.
- 50 - XY gonads first signs of meiosis.
- 70 - blood-testis barrier is definitively complete.

Rabbit implantation and placentation is a centric (or fusion) type, where the blastocyst adheres only to the epithelial cells (apical region) by trophectoderm forming projections.
- 6 - 8 somite stage - the flat neural plate transforms into a V-shaped neural groove (beginning at rhombo-cervical level)
- 8 and 9 somite stage - multiple closure sites occur simultaneously at three levels
- incipient pros-mesencephalic transition
- incipient mes-rhombencephalic transition
- level of the first pairs of somites
results in four transient neuropores
- 9-11 somite stages - anterior and rhombencephalic neuropores close
- mesencephalic neuropore is very briefly present
- largest and remains open longest
- 9-10 somite stages - tapered (cranial) portion closes fast within
- wide (caudal) portion closes up to a narrow slit
- further closure slows
- 22 somite stage - full closure occurs
compared with chick and mouse - sequence of multiple site closure resembles that of the mouse embryo, but other important aspects of neurulation resemble those of the chick embryo. In contrast to mouse and chick, no time lag between closure at the three closure sites in the rabbit was seen

Rabbit Immune Development
Rabbits generate their antibody repertoire in three stages.
- Neonatal repertoire is generated by B lymphopoiesis in fetal liver and bone marrow (limited by preferential V(H) gene segment usage).
- Between 4 and 8 weeks after birth gut-associated lymphoid tissue (GALT) a complex primary antibody repertoire.
- The primary antibody repertoire is subsequently modified during antigen-dependent immune responses (the secondary repertoire).
Rabbits uniquely develop a primary antibody repertoire through somatic diversification of Ig genes (dependent on intestinal microbial flora).
The esacculus rotundus is located at the ileocaecal junction as an enlargement of the large intestine and contains lymphoid tissue.
Postnatal Rabbit Growth
Postnatal growth data from 2 to 34 weeks of age at biweekly intervals for New Zealand white rabbit.
- 17 male and 12 female rabbits, with the data tabulated separately.
- Skeletal growth was complete at 28 weeks, with the 34 week values mature adult lengths.
Mean body weight
- 2 weeks of age was 6% that at 34 weeks
- 16 weeks was 72% of the weight at 34 weeks
- weight continued to increase in the adult.
Mean body length
- 2 weeks was 40% that at 34 weeks
- 16 weeks was 91% of mature adult
Mean femoral length
- 2 weeks was 38% of adult
- 16 weeks was 95% of adult
Mean tibial length
- 2 weeks was 38% of adult
- 16 weeks was 94% of adult
