1. Rabbits aged 3-6 months after birth, between * * and the second hair change, are referred to as "medium rabbits". At this stage of breeding management, the following points should be emphasized:

（1）飼料以青料為主，精料為輔，并注意礦物質(zhì)的補(bǔ)充，防止過肥或過瘦。

(1) The feed is mainly made of green fodder, supplemented by refined fodder, and attention should be paid to the supplementation of minerals to prevent excessive fat or weight loss.

（2）以放牧形式飼養(yǎng)，若圈養(yǎng)則要有適當(dāng)運(yùn)動(dòng)的環(huán)境。

(2) Raising in the form of grazing, if in captivity, there should be an appropriate environment for exercise.

（3）公母兔分群飼養(yǎng)，防止早配。

(3) Male and female rabbits are raised in groups to prevent early mating.

（4）同群中常會(huì)發(fā)生咬斗，在咬斗時(shí)及時(shí)撒給飼料，可制止。

(4) Biting often occurs in the same group, and timely sprinkling of feed during biting can be stopped.

（5）120天時(shí)進(jìn)行一次嚴(yán)格選育，把性狀、體型大、發(fā)育好的留作種用，編入核心群，不宜種用的公兔去勢(shì)。

(5) At 120 days, a strict selection will be conducted, and the rabbits with good traits, large body size, and good development will be kept as seeds and included in the core group. The male rabbits that are not suitable for breeding will be castrated.

（6）加強(qiáng)管理，預(yù)防疥螨、腳皮炎等傳染病。

(6) Strengthen management and prevent infectious diseases such as scabies and foot dermatitis.

2、超過6月齡的家兔稱為成兔。飼養(yǎng)管理抓好以下幾點(diǎn)：

2. Rabbits over 6 months old are called adult rabbits. Pay attention to the following points in breeding management:

（1）這一時(shí)期籠養(yǎng)。

(1) During this period, they were kept in captivity.

（2）種用公母兔要分型飼喂。母兔多喂一些堿性飼料（如青綠多汁飼料），可促進(jìn)排卵；公兔多喂一些酸性飼料（如餅類和谷類精料），可加強(qiáng)性反射和精子形成。

(2) Male and female rabbits for breeding should be fed in different types. Feeding more alkaline feed (such as green and juicy feed) to female rabbits can promote ovulation; Male rabbits can be fed more acidic feed (such as cakes and cereal concentrates) to enhance sexual reflex and sperm formation.

（3）定時(shí)定量。種公兔飼料中精料占五成，青（干）粗料占五成；種母兔飼料中精料占二成，青（干）粗料占八成。飼喂時(shí)八成飽**。

(3) Timing and quantification. Concentrated feed accounts for 50% of the feed for male rabbits, while green (dry) coarse feed accounts for 50%; In the feed for mother rabbits, refined feed accounts for 20%, and green (dry) coarse feed accounts for 80%. 80% full when feeding.

（4）保持良好的膘情。合理進(jìn)行飼喂和運(yùn)動(dòng)，防止過瘦或過肥

(4) Maintain good body fat. Reasonably feed and exercise to prevent being too thin or too fat
