What information must be included on a performance record card for a female rabbit (doe)?

Including the date bred and the buck used on a performance record card for a female rabbit (doe) is essential for breeding management. This information allows producers to track breeding cycles effectively and assess the fertility of both the doe and the buck. By recording the date of breeding, one can predict the expected kindling date, which is crucial for preparing for the birth of the kits and monitoring the doe's health during gestation. Additionally, noting the buck used enables breeders to evaluate the genetic contributions of specific pairings, aiding in selective breeding practices aimed at improving desirable traits in the offspring.

In contrast, while feed consumption and weight gain, health records and vaccination dates, and surrounding environmental conditions are important aspects of rabbit management, they do not directly pertain to the breeding specifics that impact production and breeding programs. These elements are more relevant for overall husbandry practices rather than the specific tracking of breeding performance.
