春季是兔生產的季節。因此要不失時機地搞好春季配種，減少母兔空懷，提高受配率、產仔率和成活率。每天都要檢查幼兔的健康情況，發現問題及時處理。北方的春季，溫度適宜，雨量較少，多風干燥，陽光充足，比較適于家兔生長、繁殖，是飼養家兔的好季節。

Spring is the golden season for rabbit production. Therefore, it is necessary to lose no time to do well in spring breeding, reduce the empty womb of female rabbits, and improve the mating rate, litter rate and survival rate. Check the health of the young rabbits every day and deal with any problems found in time. The spring in the north, with appropriate temperature, less rainfall, windy and dry, and sufficient sunshine, is a good season for rabbits to grow and breed.

1.飼料營養

1. feed nutrition

早春時節應對公母兔補充營養，尤其是蛋白質、維生素和微量元素。每只兔可日喂青草700克、混合精料50克。

In early spring, male and female rabbits should be supplemented with nutrition, especially protein, vitamins and trace elements. Each rabbit can feed 700g of green grass and 50g of mixed concentrate per day.

2.保溫補光

2. heat preservation and lighting

早春天氣不穩定，有時會出現倒春寒，因此要做好防寒保溫工作。對溫度低、光照少的兔舍應人工補光，確保每天有14～16小時光照時間。

The weather in early spring is unstable, and sometimes it will be cold in late spring. Therefore, it is necessary to do a good job in cold prevention and heat preservation. The rabbit houses with low temperature and little light should be artificially filled with light to ensure that there are 14 ~ 16 hours of light every day.

3.優選種兔

3. preferred breeding rabbit

春繁兔須選擇體質健壯，發育良好，種公兔性欲旺盛;種母兔生殖器官發育良好，有效乳頭4對以上，發情正常，產仔率高，護仔性強。好采取壯年公兔配壯年母兔。公母配比為1∶8～10。避免近親交配，防止品種退化。

Spring breeding rabbits must have strong physique, good development and strong sexual desire; Female rabbits have well developed reproductive organs, more than 4 pairs of effective nipples, normal estrus, high birth rate and strong baby protection. It is good to adopt a male rabbit with a female rabbit. The ratio of male and female is 1 ∶ 8 ~ 10. Avoid inbreeding and prevent variety degeneration.

4.適期配種

4. suitable breeding

蒙陰長毛兔屬刺激性排卵動物，一經公兔交配刺激后即可排卵，因而應在第1次配種后間隔8～10小時再復配1驗表明，母兔發情后陰唇濕潤紅腫，有"粉紅早、黑紫遲、老紅正當時"之說。

Mengyin long haired rabbit is a stimulating ovulatory animal. Once the male rabbit is stimulated by mating, it can ovulate. Therefore, it should be compounded at an interval of 8 ~ 10 hours after the first mating. The test shows that the labia of the female rabbit is moist and swollen after estrus, which is said to be "pink early, black purple late, and old red just in time".

5.人工輔配

5. manual auxiliary configuration

選擇性欲旺盛種公兔，把母兔放人公兔籠中，先將母兔輕輕按住，右手抓住頸皮和兩耳，左手從腹側伸入腹下后腿之間，并以大拇指和食指撐在母兔生殖器兩側，將臀部抬高呈頭低尾高姿勢，任公兔自由交配。配種后用手輕輕拍打母兔臀部，使其后軀緊張，以利精液吸入，避免倒流。待交配后8小時左右再復配1次可提高配種效果。

Select the male rabbit with strong sexual desire, put the female rabbit into the male rabbit cage, press the female rabbit gently, hold the neck skin and two ears with the right hand, extend the left hand from the ventral side to the lower hind legs of the abdomen, support the female rabbit's genitals with the thumb and index finger, and raise the hip to the posture of head low tail high, allowing the male rabbit to mate freely. After breeding, gently pat the buttocks of the female rabbit with your hands to make the hindquarters tense, so as to facilitate the inhalation of semen and avoid backflow. After 8 hours or so after mating, the effect of breeding can be improved by compounding once more.
