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）饲料以青料为主，精料为辅，并注意矿物质的补充，防止过肥或过瘦。

(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）以放牧形式饲养，若圈养则要有适当运动的环境。

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

（3）公母兔分群饲养，防止早配。

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

（4）同群中常会发生咬斗，在咬斗时及时撒给饲料，可制止。

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

（5）120天时进行一次严格选育，把性状、体型大、发育好的留作种用，编入核心群，不宜种用的公兔去势。

(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）加强管理，预防疥螨、脚皮炎等传染病。

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

2、超过6月龄的家兔称为成兔。饲养管理抓好以下几点：

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

（1）这一时期笼养。

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

（2）种用公母兔要分型饲喂。母兔多喂一些碱性饲料（如青绿多汁饲料），可促进排卵；公兔多喂一些酸性饲料（如饼类和谷类精料），可加强性反射和精子形成。

(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）定时定量。种公兔饲料中精料占五成，青（干）粗料占五成；种母兔饲料中精料占二成，青（干）粗料占八成。饲喂时八成饱**。

(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。合理进行饲喂和运动，防止过瘦或过肥

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