Rabbit Gestation Calculator
Calculate rabbit gestation with our free science calculator. Uses standard scientific formulas with unit conversions and explanations.
Formula
Due Date = Breeding Date + Gestation Period (28-35 days)
Gestation length varies by breed: dwarf breeds average 30 days, standard breeds 31 days, and giant breeds 32 days. The calculator provides earliest, expected, and latest due dates based on breed-specific ranges.
Frequently Asked Questions
How long is a rabbit pregnant?
Rabbit gestation typically lasts between 28 and 35 days, with an average of 31 days for most breeds. The exact duration depends on the breed, litter size, the individual doe, and environmental conditions. Smaller breeds like Netherland Dwarfs tend to have slightly shorter gestations around 28 to 33 days, while giant breeds like Flemish Giants may carry for 30 to 35 days. First-time does sometimes deliver a day or two later than experienced mothers. If a doe has not kindled (given birth) by day 35, veterinary consultation is recommended as this may indicate a false pregnancy, resorption of the litter, or complications requiring medical intervention.
How can you tell if a rabbit is pregnant?
Several methods can confirm rabbit pregnancy. Abdominal palpation by an experienced handler can detect grape-sized embryos at 10 to 14 days post-breeding. By day 14-18, the embryos feel like small marbles. Weight gain becomes noticeable after the second week, with the doe gaining 10 to 15 percent of her body weight during pregnancy. Behavioral changes include increased nesting behavior, hay gathering, territorial aggression, and reduced appetite in the first week followed by increased food consumption. Around days 27-30, the doe will pull fur from her dewlap and belly to line the nest. Some breeders use the fall-off method, re-introducing the doe to the buck at day 14, as pregnant does typically refuse mating aggressively.
What should you feed a pregnant rabbit?
Pregnant does require increased nutrition, especially during the latter half of gestation. For the first two weeks, maintain the normal diet of unlimited timothy hay, measured pellets (about 1/4 cup per 5 pounds of body weight), and fresh leafy greens. From day 14 onward, gradually increase pellet rations by 50 to 100 percent to support fetal growth. Alfalfa hay can replace timothy hay during late pregnancy and lactation due to its higher protein and calcium content. Fresh water must be available at all times, as dehydration can cause serious complications. Avoid sudden diet changes, which can cause gastrointestinal stress. After kindling, the nursing doe needs even more food, roughly 2 to 3 times her normal ration.
