It is very important for rex rabbits to have a good selection
The first option is to select a species. The breeding program involves assigning rabbits based on their lineage, age, coat quality, physical structure, and other traits. A matching plan is developed to ensure the best genetic combinations. All rabbits in the group are categorized into different classes—such as top-tier, second-tier, etc.—with the highest-quality ones selected as core breeding stock. These top rabbits are the main focus for seed retention, meaning that before final selection, animals are systematically evaluated to reorganize and enhance superior genes, aiming to produce outstanding individuals. Second, stage-based selection is crucial. This process is detailed and ongoing, not something that happens overnight. Observations and tests must be conducted from birth through mating and even into the third generation of offspring, identifying the most promising individuals at each stage. At least four stages are involved: weaning, three months old, early allocation, and subsequent generations. Each phase has its own focus. During weaning, key factors include the weight of weaned litters, the number of weaned kits, survival rate, and uniformity. By three months, weight, feed efficiency, and coat condition become more important. In later stages, coat quality, reproductive traits, and disease resistance are key, while future generations are judged on their ability to produce healthy offspring. Third, culling is an essential part of the process. Selection without elimination is incomplete. There is always a balance between choosing and removing. The greater the difference in performance, the higher the selection intensity, leading to better individuals being chosen. For example, if you have 300 rabbits with an average weight of 2 kg at three months, selecting half (150) could raise the average to 2.25 kg. If only 25% (75) are selected, the average might jump to 2.35 kg, and if just 10% (30) are chosen, it could reach 2.4 kg. Selecting only 5% (15) might bring the average up to 2.5 kg. This shows that the more rigorous the selection, the better the outcome. It's about constantly striving for improvement, not settling for good enough. Fourth, comparisons should be fair and comprehensive. Avoid one-sided judgments or biased competition. For instance, when selecting between two 3-month-old females, just looking at weight might lead you to pick B over A, but this may not be the best choice. You should check their history: were they littermates? How did they perform at weaning? If both had similar weaning weights, then current weight might be a valid factor. However, if one had a much lower weaning weight and now catches up, that’s a sign of potential. Additionally, when evaluating females, consider more than just weight—look at litter size, milk production, weaning survival rates, and overall health. When mating, use the same male rabbit for all females, ensuring no blood relation to maintain genetic diversity and fairness. Fifth, sufficient numbers are important for accurate selection. For example, when comparing five male rabbits, just looking at weight, size, and coat isn’t enough. They should be bred with a large enough group of females. A single litter doesn’t provide enough data. The more offspring you evaluate, the more reliable your selection becomes. This ensures that you’re not making decisions based on chance, but on consistent and measurable performance across multiple generations.
