长毛兔的繁殖效率直接决定了养殖场的经济效益。一只优秀的种兔，每年能带来4-5窝健康仔兔，而一只不合格的种兔，不仅繁殖率低，还会把劣质基因传给后代。选种配种的门道，比你想象的多得多。

The reproductive efficiency of long haired rabbits directly determines the economic benefits of the breeding farm. An excellent breeding rabbit can bring 4-5 healthy offspring per year, while an unqualified breeding rabbit not only has a low reproductive rate but also passes on inferior genes to its offspring. There are many more ways to choose and breed than you can imagine.

选种：外貌特征是非常直观的“体检报告”。 不论是引种还是自家兔场留种，一定要具备典型的品种特征。仔细观察长毛兔的外部形态特点，如体型、体格、被毛密度，非常是腹毛和腿毛密度。凡不符合本品种外貌特征的，一律不能选作种用。有生理缺陷或畸形的兔子，无论先天还是后天，同样不能留种。

Selection: Appearance is the most intuitive "physical examination report". Whether it is introducing rabbits or keeping them in one's own rabbit farm, they must have typical breed characteristics. Carefully observe the external morphological characteristics of the long haired rabbit, such as body size, physique, coat density, especially the density of abdominal and leg hair. Those that do not meet the appearance characteristics of this variety cannot be selected for planting. Rabbits with physiological defects or deformities, whether congenital or acquired, cannot be bred.

配种时机：春季是黄金季。 配种季节以春季非常好，冬季和秋季次之。配种时，兔毛长度需控制在公兔10～50天、母兔5～40天。如果兔毛超过一个月，需要把公兔腿裆的毛和母兔后尾部的毛剪短，避免影响交配。

Mating timing: Spring is the golden season. The breeding season is best in spring, followed by winter and autumn. During mating, the length of rabbit hair should be controlled between 10-50 days for male rabbits and 5-40 days for female rabbits. If the rabbit hair is over a month old, it is necessary to cut the hair on the crotch of the male rabbit and the hair on the tail of the female rabbit short to avoid affecting mating.

配种前的营养储备同样关键。配种前应加强营养，种公兔和母兔都不能过肥或过瘦。公兔可添加鱼粉、黄豆粉、麦麸、玉米、米糠和蛋壳粉等，每只每日5～100克。母兔可增喂白菜、发芽小麦和骨粉等饲料，每只每日约100克。

The nutritional reserve before mating is equally crucial. Before mating, nutrition should be strengthened, and both male and female rabbits should not be too fat or too thin. Male rabbits can be supplemented with fish meal, soybean meal, wheat bran, corn, rice bran, and eggshell powder, with 5-100 grams per day per rabbit. Female rabbits can be fed with additional feed such as cabbage, sprouted wheat, and bone meal, with each rabbit consuming approximately 100 grams per day.

粗毛型长毛兔的选配有特殊讲究。应选择体型大、性欲强、母性好、亲缘远、产毛量高、粗毛率高的兔子作种繁殖。宜采用同质选配——选择性状相同或性能表现一致的优秀公母兔配种，使优良性状更好地遗传。以年产仔4胎为例，秋季配种时公兔恢复快，可比一般兔提前10多天进行配种繁殖。

The selection of coarse haired long haired rabbits has special considerations. Rabbits with large body size, strong sexual desire, good maternal instincts, distant kinship, high hair production, and high coarse hair rate should be selected for breeding. It is advisable to use homogeneous selection - selecting excellent male and female rabbits with similar traits or performance for breeding, so that excellent traits can be better inherited. Taking the example of giving birth to four offspring per year, male rabbits recover faster during autumn mating and can breed more than 10 days earlier than regular rabbits.

母兔摸胎时机要合理。母兔配种后9～11天为摸胎的非常佳时间，对未怀孕的要及时补配，减少空怀母兔的数量，提高种兔的繁殖率。

The timing of the mother rabbit's fetal touch should be precise. The best time to touch the fetus is 9-11 days after female rabbit mating. For those who are not pregnant, timely mating should be done to reduce the number of pregnant female rabbits and improve the breeding rate of breeding rabbits.

近亲交配是繁殖的大忌。一定要控制血缘关系，杜绝近亲交配。维持血缘关系的多样性，才能保持兔群的整体繁殖品质。一只成年公兔一般能配8只母兔，公兔1天内可交配两次，休息1-2天后又可交配。母兔在6-7月龄、体重超过2.5千克，公兔在8月龄、体重超过3千克时选配非常佳。

Kinship mating is a major taboo in reproduction. It is necessary to control blood relationships and prevent inbreeding. Maintaining the diversity of blood relationships is necessary to maintain the overall reproductive quality of the rabbit population. An adult male rabbit can usually mate with 8 female rabbits. Male rabbits can mate twice within one day and can mate again after resting for 1-2 days. Female rabbits are best selected when they are 6-7 months old and weigh over 2.5 kilograms, while male rabbits are best selected when they are 8 months old and weigh over 3 kilograms.
