After 5 to 7 days post-mating, the female rabbit is returned to her original cage for a process known as "compounding." A pregnant female will typically show signs such as avoiding the male rabbit, refusing to mount him, and exhibiting restlessness or agitation. If she allows the male to mate with her, it is likely that she is not pregnant.
Another method used to determine pregnancy is the weight test. Female rabbits are weighed before mating, and then again 15 days later. A significant increase in weight may indicate pregnancy, while little to no change suggests infertility. However, this method is not highly accurate on its own and should be used in conjunction with other techniques.
A more reliable method is the "touching the fetus" technique, which is performed around 10 days after mating. The female rabbit is placed on a flat surface, and the handler gently grasps her ears and neck with one hand, positioning her head toward the abdomen. With the other hand, the fingers are positioned in an "eight" shape, and the abdomen is gently palpated from front to back along the abdominal wall. A soft, spongy feeling indicates no pregnancy, while a firm, round, elastic mass suggests the presence of embryos. It’s important to differentiate between the embryos and fecal pellets—embryos feel smooth and movable, while feces are hard and irregular.
This method is simple and effective when done correctly. However, care must be taken to handle the rabbit gently. Avoid lifting the rabbit off the ground during the examination, and never attempt to count the embryos by squeezing or pinching. Additionally, it's advisable to limit touching after day 15, as excessive handling could potentially cause a miscarriage. Overall, combining these methods increases the accuracy of pregnancy detection in rabbits.
