          長毛兔種兔的幾種不同養(yǎng)殖法:長毛兔種兔的籠養(yǎng)方式:將兔子單個或小群終年養(yǎng)在籠子里,稱為籠養(yǎng)。籠養(yǎng)是較為理想的一種飼養(yǎng)方式,尤其適于飼養(yǎng)小兔、種兔和皮 毛用兔。其優(yōu)點是便于控制家兔的生活環(huán)境、長毛兔種兔養(yǎng)殖管理、配種繁殖以及疾病防治,有利于家兔的生長發(fā)育、品種改良和提高毛皮品質(zhì)。盡管造價較高,管理費工,室內(nèi)每天須清掃,但籠養(yǎng)還是值得推廣的一種飼養(yǎng)方式。
          Several different breeding methods of Angora rabbit: the cage breeding method of Angora rabbit: single or small groups of rabbits are kept in the cage all year round, which is called cage breeding. Cage is an ideal way of raising, especially suitable for raising rabbits, breeding rabbits and fur rabbits. Its advantages are easy to control the living environment of rabbits, breeding management of Angora rabbits, breeding breeding and disease prevention, which is conducive to the growth and development of rabbits, variety improvement and fur quality improvement. Although the cost is high, the management is laborious, and the indoor cleaning is required every day, cage feeding is still a kind of breeding method worthy of promotion.
          放養(yǎng)就是把長毛兔種兔群長期在野外放牧飼養(yǎng),讓其自由采食,自由活動,自由交配繁殖,這是一種粗放的飼養(yǎng)方式。放養(yǎng)的場所,要求有充足的飼草、飼料供給其采食,并采取防護措施防止野獸的襲擊。家兔會打洞,還得防止打洞逃逸。這種方式僅適用于飼養(yǎng)肉兔。據(jù)報道,山東鄆城縣有一農(nóng)民,利用0.5平方千米的小島放養(yǎng)幾對種兔,僅兩年時間繁殖了上萬只肉兔。放養(yǎng)飼養(yǎng)主要優(yōu)點是節(jié)省人力物力,繁殖多,生長快。其缺點是亂交亂配,近親繁殖,引起品種退化,不便積肥。一旦暴發(fā)傳染病無法控制,而且毛皮質(zhì)量不高。
                                     長毛兔
          Stocking refers to the long-term grazing and feeding of Angora rabbit in the wild for a long time, allowing them to freely feed, move freely and mate freely, which is a kind of extensive feeding mode. The place where the animals are raised shall be provided with sufficient forage and feed, and protective measures shall be taken to prevent the attack of wild animals. Rabbits can burrow, but also to prevent the hole from escaping. This method is only suitable for raising meat rabbits. According to reports, a farmer in Yuncheng County, Shandong Province, used an island of 0.5 square kilometers to raise several pairs of breeding rabbits, and bred tens of thousands of meat rabbits in only two years. The main advantages of stocking are saving manpower and material resources, breeding more and growing fast. Its disadvantage is that it is disorderly crossing and mating, inbreeding, causing variety degeneration and inconvenient fertilizer accumulation. Once the outbreak of infectious diseases can not be controlled, and the quality of fur is not high.
          在室內(nèi)用竹片或小樹棍圍成柵圈,每圈占地5~6,可養(yǎng)成兔15只~20只。柵圈的向陽一側(cè)可開小門通向室外運動場,同樣用竹片或樹棍圍起來。室內(nèi)場地采用高墊草辦法,弄臟以后再墊上一層草,達一定高度,徹底墊草并,再重新墊上草。柵內(nèi)設有采食和飲水器具。柵養(yǎng)適于飼養(yǎng)商品肉兔,也可飼養(yǎng)毛兔和商品皮兔,但公兔須去勢,以便和母兔混群飼養(yǎng),不適宜飼養(yǎng)種公兔和繁殖母兔。
          In the laboratory, bamboo strips or small sticks are used to form a grid circle, each covering an area of 5-6 square meters, and 15 to 20 rabbits can be cultivated. The sunny side of the fence circle can open a small door to the outdoor sports ground, which is also surrounded by bamboo strips or sticks. The indoor ground is padded with grass. After being soiled, a layer of grass is padded to a certain height. The grass is thoroughly removed and disinfected, and then the grass is padded again. There are food and drinking water utensils in the grating. However, male rabbits should be castrated so that they can be mixed with female rabbits. It is not suitable for breeding male rabbits and breeding female rabbits.
          柵養(yǎng)可利用破舊房屋,節(jié)省人力物力,容易管理,適于戶采用。缺點是容易傳播疾病。我國北方地區(qū)冬季漫長,氣候寒冷,農(nóng)村廣泛采用地窖飼養(yǎng)。其優(yōu)點,一是節(jié)省建造長毛兔種兔,節(jié)省土地;二是符合家兔打洞習性;三是環(huán)境安靜,冬暖夏涼。缺點是,梅雨季節(jié)較為潮濕,不便于清掃與,還會影響毛皮品質(zhì)。窖養(yǎng)適于高寒干燥的地區(qū)采用。
          It is easy to manage and save manpower and material resources. The disadvantage is that it is easy to spread diseases. Due to the long winter and cold climate in northern China, cellar farming is widely used in rural areas. Its advantages are: first, it can save the price and land; second, it is in line with the rabbit's burrowing habit; third, the environment is quiet, warm in winter and cool in summer. The disadvantage is that the plum rain season is relatively humid, not easy to clean and disinfect, but also affect the quality of fur. Cellar culture is suitable for cold and dry areas.
