關于兔腸道營養的文章

英文的，看起來不太方便呀！

格式不對,看不到,怎么辦呢?

正需要這種材料，可是又沒有錢了

原來是英文版的，沒有辦法，還昨補習英語嘍

我剛翻譯了一段，對我理解反芻動物、單胃動物的營養代謝生理，幫助不小，呵呵
How to feed the rabbit (Oryctolagus cuniculus) gastrointestinal tract
如何飼喂兔子的胃腸道

ABSTRACT: Rabbits are found in virtually every country in the world, providing protein, fiber, animal research, and companionship (third to dogs and cats).
實際上我們在世界各地都可以看到兔子，他們提供蛋白質、毛皮、試驗動物和伴侶動物（僅次于狗和貓）Because of an ability to utilize low-grain and high-roughage diets, they have the potential to be a future protein source.
因為有能力利用少量谷物和大量粗纖維日糧，他們有可能是未來的蛋白質提供者， Classified as an herbivorous nonrumi-nant, rabbits have a simple, noncompartmentalized stomachalongwithanenlargedcecumandcoloninhab-ited by a microbial population (primarily Bacteroides).傳統上，作為食草而不反芻的動物，兔子有一個菌群恒定的盲腸。 Rabbits practice coprophagy, which enhances strate-gies of high feed intake (65 to 80 g/kg BW) and fast feed transit time (19 h), allowing rabbits to meet nutritional requirements. 兔子有食糞行為，這使得他們有高的采食量（占他們體重6.5%-8%）和快速腸道通過時間（19小時）Coprophagy also increases protein di-gestibility (50 vs 75–80% for alfalfa).食糞行為 也提高了蛋白質消化性（對苜蓿草而言，從50%到75%-80%）Feces are excreted on a circadian rhythm, and data indicate that the inter-nal cycle differs when shifting from ad libitum to re-stricted feeding.可吃的糞便按照固定周期排出，但是這個周期隨飼養習慣而調整（自由采食還是按頓飼喂） Microbes digest cellulose (14% in rab-bits vs 44% in cattle) in the hindgut of the rabbit,在盲腸后段，細菌可消化纖維素只有14%，奶牛有44%, but the contribution of amino acids from microbial protein is thought to be minimal. 不過一般認為由微生物蛋白提供的氨基酸有限，Lysine and methionine may be limited in traditional diets, and urea is not utilized.傳統日糧中，賴氨酸和蛋氨酸是限制性氨基酸，尿素無效。 Acetate is the primary microbial VFA, with more buty-rate than propionate. 乙酸和丁酸是主要揮發性脂肪酸（VFA），而非丙酸。Unlike ruminants, more VFA are produced on starch than on forage diets; 與反芻動物不同，他們的揮發性脂肪酸（VFA）主要由淀粉產生，而不是由草料產生。however, VFA provide limited energy for maintenance. 不過，VFA提供的能量對生命而言很有限。Fiber is essen-tial to maintain gut health, stimulate gut motility (in-soluble fiber only), and reduce fur chewing.纖維主要的作用是：維持腸道健康、刺激腸道蠕動（非水溶性纖維）和減少吃毛行為 Low-fiber diets result in gut hypomotility,低纖維日糧導致腸道運動不足， reduced cecotrope for-mation, and prolonged retention time in the hindgut.減少了cecotrope生成和延遲了盲腸糞便停留時間。 High-starch diets may be incompletely digested in the small intestine due to rapid transit times, resulting in enteritis.高淀粉日糧會因為小腸的快速通過時間無法徹底消化，從而導致腸炎。 Low-energy grains like oats are preferred.因此，低能量谷物如燕麥會更好。 Low-protein concentrations increase cecotrope consumption and high levels decrease it.低蛋白濃度增加cecotrope的消耗，高濃度則相反。

是的,兔子肉好,能量低,不飽和脂肪酸高,飼料利用率高,節省玉米和豆粕,最適合我國國情.將來一定會大發展的,就差政府引導消費了

感謝vetqq，感謝王博士的翻譯，受益匪淺！希望有機會多得到這些信息！
