兔用粗飼料主要包括干草和稿稈兩大類。其中常見的有干青草、干苕糠、干甘薯藤、豆秸、玉米稈、統(tǒng)糠等。這些粗飼料要怎樣選用才好，我們可以其處理方法和營養(yǎng)價值為標準來選用。
Rabbit forage mainly includes two kinds of hay and straw. The most common are dry grass, dry potato bran, dry beans, sweet potato vine, corn stalk, rice bran etc.. How to choose these roughage to be good, we can choose its treatment methods and nutritional value as the standard.
就干草來說，可用自然干燥和人工干燥兩種方法來完成青草的干制。自然干制是利用陽光或環(huán)境溫度使飼料脫水，達到干制目的。此法所制干草營養(yǎng)成分損失在20%左右，胡蘿卜素損失在70%~80%。其中豆科干草的營養(yǎng)價值更好。人工干制（低溫干制和高溫干制）的優(yōu)點是營養(yǎng)素損失少，僅為自然干制損失的1/3~1/10。
In the case of hay, two methods can be used to dry the grass. Natural drying is the use of sunlight or ambient temperature to feed dehydration, dry purpose. In this method, the loss of nutrients in the hay was about 20%, and the loss of carotene was 70%~80%. Among them, legume hay had the best nutritional value. The advantage of artificial drying (low temperature drying and high temperature drying) is the loss of nutrients, which is only 1/3~1/10.
人工干制中，低溫干制是將熱源溫度控制在幾十度到500℃之間，經(jīng)數(shù)小時，使飼料中水分降低到14%~17%?？偟膩碚f，有機物質(zhì)的損失程度自然干制大于人工干制，低溫干制大于高溫干制，所以選用人工高溫干制的干草營養(yǎng)價值較好，但若考慮飼料成本，則以自然干制的成本更低；豆科干草較禾本科干草營養(yǎng)價值好，應優(yōu)先考慮。應注意的是：人工干制的干草維生素損失較大，使用時應考慮飼料中維生素的缺乏，相應添加維生素或?qū)Ｓ枚嗑S來滿足。
Artificial drying, low temperature drying is to control the temperature of the heat source in a few degrees to 500 degrees C, after a few hours, so that the feed water to 14%~17%. In general, the degree of loss of organic material in the natural drying than artificial drying, low temperature drying than high temperature drying, so the artificial high temperature dry hay nutritive value for the better, but if we consider the cost of feed, with natural drying of the lowest cost; compared with cereal legume hay hay nutrient value, should be given priority consider. It should be noted that: artificial dried hay vitamin loss, should be considered when using the lack of vitamins in the feed, the corresponding vitamin or vitamin C to meet the specific.
稿稈類中，小麥草質(zhì)地粗糙、堅硬、葉帶盲刺，有機物消化率低；大麥草質(zhì)地優(yōu)于小麥草，春大麥草又比冬大麥草質(zhì)量好；燕麥草質(zhì)地軟，稈光滑，不帶盲刺，是農(nóng)作物稿稈中更好的；稻草木質(zhì)素含量低，硅含量高，飼養(yǎng)價值低，因而喂兔效果不好，適口性差，飼料報酬極低。
In the straw, wheat grass, hard, rough texture leaves with blind thorn, digestibility of organic matter is low; barley grass texture is better than wheat grass, wheat straw and spring than winter barley grass quality; oat grass stalk soft texture, smooth, without blind thorn, is the best crop straw in rice straw lignin content; low, high silicon content, low feeding value, thus feeding rabbit effect is not good, poor palatability, feed efficiency is very low.
相信看了本文的介紹后，對長毛兔http://gdwk56.com這方面也會有自己的一番認識，以后針對的等問題也能很好的解決。
I believe that after reading the introduction of this article, the long haired rabbit http://gdwk56.com in this regard will have their own understanding of the future and other issues can also be a good solution.
