1、 Scientifically determine the initial mating age

确定肉兔的初配年龄，主要根据体重和月龄来决定，在正常饲养管理条件下，公母兔体重达到该品种标准体重的70%时，即已达到体成熟，可开始配种繁殖。一般小型品种初配年龄为4-5月龄，体重2.5-3千克。中型品种为5-6月龄，体重3.5-4千克。大型品种为7-8月龄，体重4.5-6千克。因公兔性成熟年龄比母兔迟，所以公兔的初配年龄应比母兔迟1个月左右。为了防止早配和近亲交配，在家兔性成熟前应公母分开饲养。

The initial mating age of meat rabbits is mainly determined according to the weight and month age. Under normal feeding and management conditions, when the weight of male and female rabbits reaches 70% of the standard weight of the variety, they have reached body maturity and can start breeding. Generally, the initial mating age of small varieties is 4-5 months old and the weight is 2.5-3kg. The medium-sized varieties are 5-6 months old and weigh 3.5-4kg. The large variety is 7-8 months old and weighs 4.5-6 kg. Because the sexual maturity age of male rabbits is later than that of female rabbits, the initial mating age of male rabbits should be about 1 month later than that of female rabbits. In order to prevent early mating and inbreeding, male and female rabbits should be raised separately before sexual maturity.

二、科学确定使用年限

2、 Scientifically determine the service life

适时淘汰和更新兔群。公母兔的使用年限一般为3-4年，如果体质健壮，使用合理，配种利用年限可适当延长。但过于衰老，其受胎率、产仔数和成活率均差，所产仔兔品质也差，所以要适时淘汰和更新兔群。一般每年淘汰1/3，做到3年－轮换，让适龄种兔在兔群中占优势。

Timely eliminate and update the rabbit population. The service life of male and female rabbits is generally 3-4 years. If they are strong and reasonably used, the service life of breeding can be appropriately extended. However, it is too old, its conception rate, litter size and survival rate are poor, and the quality of newborn rabbits is also poor. Therefore, it is necessary to eliminate and update the rabbit population in time. Generally, 1 / 3 of the rabbits are eliminated every year, so that the three-year rotation can be achieved, so that the breeding rabbits of school age have an absolute advantage in the rabbit population.

三、科学安排配种繁殖季节

3、 Arrange breeding season scientifically

掌握好肉兔的配种繁殖季节是提高仔兔成活率的重要环节，肉兔繁殖虽无明显的季节性，一年四季均可配种繁殖，但因不同季节的温度、光照、营养状况等不同，对母兔的受胎率和仔兔成活率均有一定的影响。

Mastering the breeding season of meat rabbits is an important link to improve the survival rate of young rabbits. Although the breeding of meat rabbits has no obvious seasonality and can be bred all year round, it has a certain impact on the conception rate of female rabbits and the survival rate of young rabbits due to the different temperature, light and nutritional status in different seasons.

1、春、秋季。气候温和、干燥、种兔性欲旺盛，母兔受胎率高，产仔数多，仔兔成活率高，是肉兔配种繁殖的好季节，要抓好配种繁殖工作。不少兔场春繁大都采用频密产仔法（血配），连产2-3胎后，再行调整，恢复体力，8月份开始秋繁。

1. Spring and autumn. The climate is mild and dry, the sexual desire of breeding rabbits is strong, the conception rate of female rabbits is high, the number of births is large, and the survival rate of young rabbits is high. It is the best season for meat rabbit breeding. We should pay attention to breeding. Many rabbit farms mostly adopt the frequency and density method (blood matching) for spring breeding. After giving birth to 2-3 fetuses, they will adjust again to recover their physical strength, and autumn breeding will begin in August.

2、夏季。凡舍温在30摄氏度以上的时节，应停止配种繁殖，一般是在每年的6月份7月中旬停止配种繁殖。但如母兔体质健壮，又有防暑条件，仍可适当安排配种繁殖。

2. Summer. When the shewen is above 30 ℃, breeding should be stopped, generally from June to mid July every year. However, if the female rabbit is strong and has heatstroke prevention conditions, breeding can still be arranged appropriately.
