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： 肥育兔尖限制運動，因此在實踐中應增加密度，成年兔每6-8只為宜，每群20-30只為宜，這樣便于管理。

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：分群時盡量能將公母兔分開飼養，利于飼養管理和促進肉兔的生長發育。

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、弱強分群： 同一群中體重、體質應盡量均等，這樣不僅有利于兔的生長發育，也可在一定程度上防止兔群爭斗。

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、同窩合群： 分在同一群的肉兔應盡量是同窩仔兔，如果不是同窩合群，也應選擇日齡相同的仔肉兔并群。

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、每只瘦兔每天喂紅糖7克或白糖5克（溶于溫熱開水中拌入飼料中飼喂），連喂10-15天，可使瘦兔明顯增膘。

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，硫酸亞鐵、甘草各10克，八角9克，共研細末，每只兔每次拌料喂給2克，每天一次，增膘效果顯著。

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、黃豆粉6%（炒熱）、大茴香粉7%、硫酸亞鐵8%、甘草粉9%、干姜粉20%、肉桂粉50%，充分混合拌入料中，并加適量水拌勻，每只兔每天喂3克，隔天喂1次，15天后增重明顯，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、取中藥雷丸、陳皮、厚樸、香附各5克，山楂12克，共研細末，拌入飼料中喂兔或將藥粉直接對水灌服，每日1次，連用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、給兔喂“兔促長”復合添加劑，直接拌入飼料中飼喂即可。每隔每天喂一次，連喂5次，能明顯使兔增膘。

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.
