The age at which rabbit meat should be harvested can vary depending on several factors, including the specific breed of the rabbit and the desired meat quality. In general, rabbits are typically harvested for meat between 8 and 12 weeks of age.

At around 8 weeks of age, rabbits have reached a good size for meat production, and their meat is tender and flavorful. Harvesting them at this age ensures that the meat is not too tough or gamey.

However, some breeders prefer to wait until around 12 weeks of age to allow the rabbits to reach a slightly larger size, resulting in more meat yield per rabbit. Keep in mind that as rabbits age, their meat can become slightly tougher, so there is a balance between meat yield and meat quality.

It's important to note that rabbits should be harvested before sexual maturity to avoid any changes in meat quality or taste that can occur with hormonal changes. Additionally, rabbits should be harvested humanely and following proper animal welfare guidelines.

If you are new to raising rabbits for meat, it can be helpful to consult with experienced breeders or farmers who can provide guidance specific to the breed you are working with and the intended purpose of your rabbitry.
