1、 Scientifically determine the initial mating age

確定肉兔的初配年齡，主要根據體重和月齡來決定，在正常飼養管理條件下，公母兔體重達到該品種標準體重的70%時，即已達到體成熟，可開始配種繁殖。一般小型品種初配年齡為4-5月齡，體重2.5-3千克。中型品種為5-6月齡，體重3.5-4千克。大型品種為7-8月齡，體重4.5-6千克。因公兔性成熟年齡比母兔遲，所以公兔的初配年齡應比母兔遲1個月左右。為了防止早配和近親交配，在家兔性成熟前應公母分開飼養。

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、科學確定使用年限

2、 Scientifically determine the service life

適時淘汰和更新兔群。公母兔的使用年限一般為3-4年，如果體質健壯，使用合理，配種利用年限可適當延長。但過于衰老，其受胎率、產仔數和成活率均差，所產仔兔品質也差，所以要適時淘汰和更新兔群。一般每年淘汰1/3，做到3年－輪換，讓適齡種兔在兔群中占優勢。

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、科學安排配種繁殖季節

3、 Arrange breeding season scientifically

掌握好肉兔的配種繁殖季節是提高仔兔成活率的重要環節，肉兔繁殖雖無明顯的季節性，一年四季均可配種繁殖，但因不同季節的溫度、光照、營養狀況等不同，對母兔的受胎率和仔兔成活率均有一定的影響。

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。氣候溫和、干燥、種兔性欲旺盛，母兔受胎率高，產仔數多，仔兔成活率高，是肉兔配種繁殖的好季節，要抓好配種繁殖工作。不少兔場春繁大都采用頻密產仔法（血配），連產2-3胎后，再行調整，恢復體力，8月份開始秋繁。

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。凡舍溫在30攝氏度以上的時節，應停止配種繁殖，一般是在每年的6月份7月中旬停止配種繁殖。但如母兔體質健壯，又有防暑條件，仍可適當安排配種繁殖。

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.
