关于兔肠道营养的文章

英文的，看起来不太方便呀！

格式不对,看不到,怎么办呢?

正需要这种材料，可是又没有钱了

原来是英文版的，没有办法，还昨补习英语喽

我刚翻译了一段，对我理解反刍动物、单胃动物的营养代谢生理，帮助不小，呵呵
How to feed the rabbit (Oryctolagus cuniculus) gastrointestinal tract
如何饲喂兔子的胃肠道

ABSTRACT: Rabbits are found in virtually every country in the world, providing protein, fiber, animal research, and companionship (third to dogs and cats).
实际上我们在世界各地都可以看到兔子，他们提供蛋白质、毛皮、试验动物和伴侣动物（仅次于狗和猫）Because of an ability to utilize low-grain and high-roughage diets, they have the potential to be a future protein source.
因为有能力利用少量谷物和大量粗纤维日粮，他们有可能是未来的蛋白质提供者， Classified as an herbivorous nonrumi-nant, rabbits have a simple, noncompartmentalized stomachalongwithanenlargedcecumandcoloninhab-ited by a microbial population (primarily Bacteroides).传统上，作为食草而不反刍的动物，兔子有一个菌群恒定的盲肠。 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. 兔子有食粪行为，这使得他们有高的采食量（占他们体重6.5%-8%）和快速肠道通过时间（19小时）Coprophagy also increases protein di-gestibility (50 vs 75–80% for alfalfa).食粪行为 也提高了蛋白质消化性（对苜蓿草而言，从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.可吃的粪便按照固定周期排出，但是这个周期随饲养习惯而调整（自由采食还是按顿饲喂） Microbes digest cellulose (14% in rab-bits vs 44% in cattle) in the hindgut of the rabbit,在盲肠后段，细菌可消化纤维素只有14%，奶牛有44%, but the contribution of amino acids from microbial protein is thought to be minimal. 不过一般认为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.传统日粮中，赖氨酸和蛋氨酸是限制性氨基酸，尿素无效。 Acetate is the primary microbial VFA, with more buty-rate than propionate. 乙酸和丁酸是主要挥发性脂肪酸（VFA），而非丙酸。Unlike ruminants, more VFA are produced on starch than on forage diets; 与反刍动物不同，他们的挥发性脂肪酸（VFA）主要由淀粉产生，而不是由草料产生。however, VFA provide limited energy for maintenance. 不过，VFA提供的能量对生命而言很有限。Fiber is essen-tial to maintain gut health, stimulate gut motility (in-soluble fiber only), and reduce fur chewing.纤维主要的作用是：维持肠道健康、刺激肠道蠕动（非水溶性纤维）和减少吃毛行为 Low-fiber diets result in gut hypomotility,低纤维日粮导致肠道运动不足， reduced cecotrope for-mation, and prolonged retention time in the hindgut.减少了cecotrope生成和延迟了盲肠粪便停留时间。 High-starch diets may be incompletely digested in the small intestine due to rapid transit times, resulting in enteritis.高淀粉日粮会因为小肠的快速通过时间无法彻底消化，从而导致肠炎。 Low-energy grains like oats are preferred.因此，低能量谷物如燕麦会更好。 Low-protein concentrations increase cecotrope consumption and high levels decrease it.低蛋白浓度增加cecotrope的消耗，高浓度则相反。

是的,兔子肉好,能量低,不饱和脂肪酸高,饲料利用率高,节省玉米和豆粕,最适合我国国情.将来一定会大发展的,就差政府引导消费了

感谢vetqq，感谢王博士的翻译，受益匪浅！希望有机会多得到这些信息！
