When reviewing original records, it is essential to work directly with the original data and ensure its completeness. Careful examination of the selected data is necessary, and decisions should be based strictly on the information provided rather than relying on superficial observations or personal biases.
It is recommended to select breeding rabbits during the third to fifth litters, as this period has proven to be ideal for identifying quality individuals.
The number of over-selected breeding animals should be significantly higher than the actual needs—3 to 4 times more for females and 5 to 10 times more for males. Female rabbits should have at least 8 teats, which should be well-balanced and fully developed. Those that have two to three consecutive litters with fewer than four live births, or four consecutive litters with less than four surviving offspring, should be culled. Additionally, females with low milk production, poor maternal instincts, or signs of poor health, such as being overweight or showing signs of disease, should not be retained.
Male rabbits must be chosen with even greater care and stricter criteria. They should come from purebred lines, be healthy, free of diseases, well-developed, and active. Their testicles should be firm, symmetrical, and show strong sexual drive. Any male with a history of delayed growth, single testicle, cryptorchidism, or low libido should not be used for breeding.
Individuals selected for breeding should meet the established standards and align with national breeding guidelines. This ensures consistency and quality in the breeding program.
Over time, as the population is continuously bred, the coefficient of inbreeding will inevitably increase. To prevent negative effects from inbreeding, it's important to introduce new bloodlines periodically. Exchanging rabbits with nearby rabbit farms is an effective way to maintain genetic diversity and improve overall herd quality.
