    長毛兔養(yǎng)殖的發(fā)展趨勢

    發(fā)布日期:2024-03-16 來源:http://www.tunjie.cn 發(fā)布人:創(chuàng)始人

    隨著家庭養(yǎng)兔業(yè)的恢復和發(fā)展,出現(xiàn)了高度集約化、現(xiàn)代化的兔場。封閉式的兔舍,自動控制溫濕度,自動喂食飲水,自動糞便,不僅大大提高了勞動效率,而且不受季節(jié)影響,可以進行集約化養(yǎng)殖。在德國,有300只母兔和50只公兔在羊毛養(yǎng)殖場。每只母兔每年繁殖3-10次,平均30多只幼兔,僅5個人管理,全部機械化自動化。

    With the recovery and development of family rabbit farming, highly intensive and modern rabbit farms have emerged. A closed rabbit house with automatic control of temperature and humidity, automatic feeding and drinking water, and automatic removal of feces not only greatly improves labor efficiency, but also is not affected by seasons, allowing for intensive breeding. In Germany, there are 300 female rabbits and 50 male rabbits in wool farms. Each female rabbit breeds 3-10 times a year, with an average of over 30 young rabbits managed by only 5 people and fully mechanized and automated.

    隨著規(guī)模化、集約化、現(xiàn)代化兔業(yè)的興起,飼料加工出現(xiàn)了工廠化、化、營養(yǎng)成分標準化、飼料形狀顆粒化的趨勢。一些,如美國、英國、德國、法國等。制定了飼養(yǎng)標準和飼料配方。全價顆粒飼料由飼料公司供應,如德國賽斯兔場、英國凱美瑞公司農(nóng)場;在美國。根據(jù)哺乳期、妊娠期、斷奶期、配種期的要求分別配制顆粒飼料,上市銷售。

    With the rise of large-scale, intensive, and modern rabbit industry, there has been a trend of industrialization, specialization, standardization of nutritional components, and granulation of feed shape in feed processing. Some countries, such as the United States, the United Kingdom, Germany, France, etc. Established feeding standards and feed formulas. Full price pellet feed is supplied by feed companies such as Seth Rabbit Farm in Germany and Camry Farm in the UK; in the U.S. Prepare pellet feed according to the requirements of lactation, pregnancy, weaning, and breeding periods, and sell it on the market.

    近年來,國外十分重視毛兔的育種工作,并取得了迅速的進展。育種的主要是ht和兔毛質(zhì)量,而不是頭型和外觀。比如德國安哥拉兔的敏感度幾乎已經(jīng)達到了兔子所能適應的極限。公兔年均產(chǎn)毛量達到1190克,母兔達到1406克,公兔達到1720克,母兔達到2036克。法國對安哥拉兔的育種側(cè)重于粗毛含量和毛纖維的長度和強度,已培育出粗毛含量在15%以上的粗毛兔。

    In recent years, foreign countries have attached great importance to the breeding of rabbits and have made rapid progress. The focus of breeding is mainly on HT and rabbit hair quality, rather than head shape and appearance. For example, the sensitivity of German Angora rabbits has almost reached the limit that rabbits can adapt to. The average annual wool production of male rabbits reaches 1190 grams, while that of female rabbits reaches 1406 grams, and that of male rabbits reaches 1720 grams and that of female rabbits reaches 2036 grams. France's breeding of Angora rabbits focuses on the coarse wool content and the length and strength of wool fibers, and has cultivated coarse wool rabbits with a coarse wool content of over 15%.

    飼養(yǎng)長毛兔有利有弊。飼養(yǎng)長毛兔也有以下兩個缺點:

    Raising long haired rabbits has both advantages and disadvantages. Raising long haired rabbits also has the following two drawbacks:

    一、 易得病

    1、 Easy to get sick

    長毛兔和兔子一樣,死一窩。如果疫情不及時預防,兔子可能會全軍覆沒。但如果定期接種疫苗,實時觀察,暴發(fā)的概率也很小。

    Long haired rabbits, like rabbits, die in one litter. If the epidemic is not prevented in a timely manner, rabbits may be completely wiped out. But if vaccinated regularly and observed in real-time, the probability of an outbreak is also very low.

    二、 市場有風險

    2、 There is a risk in the market

    任何牲畜養(yǎng)殖都是有風險的,兔毛不升反降。所以在養(yǎng)殖初期,要考察市場,查養(yǎng)殖書籍,才能穩(wěn)中求勝。

    Any livestock farming carries risks, and the price of rabbit hair will decrease instead of increase. So in the early stages of breeding, it is necessary to examine the market and consult breeding books in order to win steadily.
