In spring, rabbits are thin and weak due to lack of forage. If they are not properly fattened, the breeding and death of rabbits will be affected. There are two methods for fattening rabbits in spring

一、管理

1、 Management

1、合理的密度： 肥育兔尖限制运动，因此在实践中应增加密度，成年兔每6-8只为宜，每群20-30只为宜，这样便于管理。

1. Reasonable density: fattening rabbit tip limits movement, so we should increase the density in practice, 6-8 adult rabbits per square meter is appropriate, 20-30 rabbits per group is appropriate, so as to facilitate management.

2、公母分群：分群时尽量能将公母兔分开饲养，利于饲养管理和促进肉兔的生长发育。

2. Male and female grouping: when grouping, male and female rabbits should be raised separately as far as possible, which is conducive to feeding management and promoting the growth and development of meat rabbits.

3、弱强分群： 同一群中体重、体质应尽量均等，这样不仅有利于兔的生长发育，也可在一定程度上防止兔群争斗。

3. Weak strong grouping: in the same group, the weight and physique should be equal as far as possible, which is not only conducive to the growth and development of rabbits, but also can prevent rabbits from fighting to a certain extent.

4、同窝合群： 分在同一群的肉兔应尽量是同窝仔兔，如果不是同窝合群，也应选择日龄相同的仔肉兔并群。

4. In the same nest: in the same group of rabbits should try to be the same nest, if not in the same nest, should also choose the same age of rabbits and group.
                  

二、催肥

2、 Fattening

1、每只瘦兔每天喂红糖7克或白糖5克（溶于温热开水中拌入饲料中饲喂），连喂10-15天，可使瘦兔明显增膘。

1. Each lean rabbit was fed with 7g brown sugar or 5g white sugar (dissolved in warm boiled water and mixed with feed) every day for 10-15 days, which could significantly increase fat.

2、肉桂50克，姜粉25克，硫酸亚铁、甘草各10克，八角9克，共研细末，每只兔每次拌料喂给2克，每天一次，增膘效果显着。

2. Cinnamon 50 grams, ginger powder 25 grams, ferrous sulfate, licorice 10 grams, anise 9 grams, a total of fine grinding, each rabbit each time feed 2 grams, once a day, fattening effect is significant.

3、黄豆粉6%（炒热）、大茴香粉7%、硫酸亚铁8%、甘草粉9%、干姜粉20%、肉桂粉50%，充分混合拌入料中，并加适量水拌匀，每只兔每天喂3克，隔天喂1次，15天后增重明显，平均每天可增重35-50克。

3. Soybean powder 6% (stir fried), fennel powder 7%, ferrous sulfate 8%, licorice powder 9%, dried ginger powder 20%, cinnamon powder 50%, fully mixed into the material, and add appropriate amount of water to mix well. Each rabbit was fed 3 g every day, once every other day. After 15 days, the weight gain was obvious, with an average of 35-50 g per day.

4、取中药雷丸、陈皮、厚朴、香附各5克，山楂12克，共研细末，拌入饲料中喂兔或将药粉直接对水灌服，每日1次，连用3-5日。

4. Take 5 grams of leiwan, tangerine peel, Magnolia officinalis and Xiangfu, and 12 grams of hawthorn, grind them into fine powder, mix them into the feed and feed the rabbits or take the powder directly with water, once a day for 3-5 days.

5、给兔喂“兔促长”复合添加剂，直接拌入饲料中饲喂即可。每隔每天喂一次，连喂5次，能明显使兔增膘。

5. The rabbits were fed with the compound additive of "rabbit growth promoting" and directly mixed into the feed. Feeding once every day for five times can significantly increase the fat of rabbits.
