兔子主要是用粗飼料。所謂粗飼料,是指干物質(zhì)中粗纖維含量大于或等于18%,單位飼料容積大的飼料。兔用粗飼料主要包括干草或稿稈兩大類。其中常見的有干青草、干苕藤、豆秸、玉米稈等。
Rabbits are mainly fed roughage. The so-called roughage, refers to the dry matter content of crude fiber is greater than or equal to 18%, the unit feed volume is large feed. Rabbit roughage mainly includes hay or straw. Among them, the common ones are dried green grass, dried vetch vine, soybean straw, corn stalk and so on.
這些粗飼料要怎樣選用才好,我們可以根據(jù)處理方法和營養(yǎng)價值為標準來選用。就干草來說,以選用人工高溫干制的營養(yǎng)價值較好,但若考慮飼料成本,則以自然干制的成本低;豆科干草較禾本科干草營養(yǎng)價值好,應(yīng)優(yōu)先考慮。應(yīng)注意的是,人工干制的干草維生素損失較大,使用時應(yīng)考慮飼料中維生素的缺乏,相應(yīng)添加維生素或?qū)S枚嗑S來滿足。
How to choose these roughages? We can choose them according to the treatment method and nutritional value. As far as hay is concerned, artificial high-temperature drying has better nutritional value, but natural drying has lower cost if feed cost is considered; legume hay has better nutritional value than gramineous hay, so it should be given priority. It should be noted that the vitamin loss of artificial dried hay is large, and the lack of vitamin in feed should be considered when using, and the vitamin or special multidimensional should be added accordingly.
稿秕類中,小麥草質(zhì)地粗糙、堅硬,硅含量高,葉帶盲刺,有機物消化率低;大麥草質(zhì)地優(yōu)于小麥草,春大麥草比冬大麥草質(zhì)地好;燕麥草質(zhì)地軟,稈滑,不帶盲刺,是稿稈中好的;稻草木質(zhì)素含量高,飼用價值較低??傊祟愶暳腺|(zhì)地堅硬,粗纖維中木質(zhì)素含量高,飼用價值不高,而花生藤、大豆稈等是較好的稿稈飼料。
Among the chaff species, wheatgrass has rough and hard texture, high silicon content, blind thorns in leaves and low organic matter digestibility; barley grass has better texture than wheatgrass, spring barley grass has better texture than winter barley grass; oat grass has soft texture, slippery stalk and no blind thorns, which is better in straw; rice straw has higher lignin content and lower feeding value. In a word, this kind of feed has hard texture, high lignin content in crude fiber and low feeding value, while peanut vine and soybean stalk are better straw feed.

粗飼料中用干草喂兔較稿秕飼料好。一般干草在配合飼料中可占20%-30%,而稿秕飼料則不宜超過20%。另外,粗飼料一般宜粉碎后與精料混合使用(制成顆?;虬铦?。禾本科干草可喂兔,粉碎時不宜過細,過細的粉末反而不利于家兔的正常消化和排泄,其細度以便于與其它精料混勻,家兔喜歡采食。特別值得注意的是統(tǒng)糠,在農(nóng)村中用得很廣,是一種質(zhì)量較差的粗飼料,很多農(nóng)戶都用它與麩皮等混合來喂兔,然而統(tǒng)糠不適宜喂斷奶兔,就是喂大兔和肥育兔,用量也不宜超過15%。
In roughage, it is better to feed rabbits with hay than with chaff. In general, hay can account for 20% - 30% of the formula feed, but the proportion of draft chaff feed should not exceed 20%. In addition, roughage should be crushed and mixed with concentrate (made into granules or mixed wet). Fine gramineous hay can be fed to rabbits. It should not be too fine when crushed. The fine powder is not conducive to the normal digestion and excretion of rabbits. The fineness is so that it can be mixed with other concentrate. Rabbits like to eat it. In particular, it is worth noting that Tong bran is widely used in rural areas. It is a kind of roughage with poor quality. Many farmers use it mixed with bran to feed rabbits. However, Tong bran is not suitable for weaning rabbits. Even for big rabbits and fattening rabbits, the dosage should not exceed 15%.
由于青飼料和粗飼料中能量和蛋白質(zhì)含量較低,不能滿足家兔高產(chǎn)的營養(yǎng)需要,尤其是良種兔。只喂青粗飼料會導(dǎo)致家兔生長發(fā)育緩慢、身體素質(zhì)下降、母兔繁殖和泌乳量下降、產(chǎn)肉力下降等,這就需要喂精料。所謂精料是指一類體積小、粗纖維含量少、含能量或蛋白質(zhì)較高的飼料,用來調(diào)整兔飼料能量和蛋白質(zhì)水平以滿足兔生長發(fā)育、繁殖、泌乳、育肥需要的主要飼料。麥類、谷物、玉米、豆類等籽實及其加工副產(chǎn)物如米糠、麥麩、油餅、豆渣等都是兔常用的精飼料。精飼料又包括能量飼料和蛋白質(zhì)飼料。
Due to the low content of energy and protein in green fodder and roughage, it can not meet the high-yield nutritional needs of rabbits, especially the improved breed rabbits. Feeding only green roughage will lead to the slow growth and development of rabbits, the decline of physical fitness, the decline of reproduction and lactation of female rabbits, the decline of meat production and so on. The so-called concentrate is a kind of feed with small volume, low crude fiber content, high energy or protein content, which is used to adjust the energy and protein level of rabbit feed to meet the needs of rabbit growth, reproduction, lactation and fattening. Wheat, grain, corn, beans and their by-products such as rice bran, wheat bran, oil cake, soybean residue are commonly used as concentrate feed for rabbits. Concentrate feed includes energy feed and protein feed.
兔是一種單胃草食動物,用草可把兔子喂大,單純的精料則會導(dǎo)致兔子消化不良,引起腹瀉等消化道疾病甚死亡。所以,精料必須搭配粗料制成全價配合飼料才能喂兔。從另一角度講,精飼料雖然營養(yǎng)價值高,適口性好,但較貴。所以,為了節(jié)約成本,我們也應(yīng)選用精粗飼料作合理搭配。
Rabbit is a kind of single stomach herbivore, which can be fed with grass. Pure concentrate will lead to indigestion, diarrhea and other gastrointestinal diseases, even death. Therefore, the concentrate must be combined with the roughage to make a full price formula feed in order to feed rabbits. On the other hand, although concentrate has high nutritional value and good palatability, it is expensive. Therefore, in order to save cost, we should also choose concentrate and roughage as a reasonable mix.
