参考兔子对纤维的需求:怎样管理兔子的胃肠道

月上柳梢头

值得参考的一篇文章,分类介绍了兔子对不同营养的消化利用生理,请读者仔细查阅,这里列出几条关键词句:
When compared with other herbivores,actual fiber digestion capability for rabbits is relatively low (14% for alfalfa hay in rabbits compared with 44% in cattle, 41% in horses, and 22% in hogs) (McNitt et al., 1996).

和其他动物比较,兔子对纤维的消化力是相对低的, 消化率以苜蓿干草为例:兔14%,牛44%,马41%,猪 22%.

In rabbits, dietary fiber has a critical role in maintaining gut health, stimulating gut motility (insoluble fiber only), reducing fur chewing, and preventing enteritis (McNitt, et al., 1996; Brooks, 1997).
对兔子而言,纤维应用的典型原则是保持肠道健康,刺激肠道蠕动(只有不溶性纤维才具有这个功能),减少食毛症(这里提一句:肉鸡的啄羽情况也类似于和纤维的缺乏有关), 和防止肠炎.

Gut microflora of rabbits are sensitive to most antibiotics (McNitt et al., 1996). If antibiotics are fed, the microbe
population is altered, favoring E. coli and Clostridia organisms that produce toxins harming the gut lining,
causing diarrhea and enterotoxemia (Cheeke, 1994;Stein and Walshaw, 1996; Brooks, 1997).
维持兔子的肠道微生物区系平衡很重要,微生物区系很敏感,如果饲喂抗生素,将打破有益菌的区系平衡,帮助大肠杆菌和梭菌分泌毒素,破坏肠道,造成腹泻,肠毒血症.(唉~不只是兔子了,滥用抗生素的后果,继发问题一堆)

Care should be taken when feeding high levels of dietary protein because excess protein may increase cecal ammonia levels, causing an increase in cecal pH (Cheeke, 1994). This rise in pH may allow pathogens to flourish and may increase the potential for enteritis.
蛋白部分,前文提及兔子不能使用菌体蛋白,但能很好的使用如苜蓿草粗料蛋白 ,比猪用的好,同时盲肠的微生物也能利用少量的尿素,但若过量产生的氨会有毒副作用, 这里说:使用高水平蛋白原料需要慎重,因为过量的蛋白会增加盲肠的氨含量,提高PH,为致病菌的抬头创造条件.

淀粉部分提及,兔子小肠对淀粉的利用不完全,往往代谢产物进入后肠发酵,同时为梭菌所利用,造成胀气腹泻等,因此兔子倾向选择降解慢的原料.如燕麦.

because rabbits prefer not to eat the fines. If an animal does eat too many fines or if the particle size is too small, there will be an increase in retention time in the gut, reduced gut motility, and enteritis. Large indigestible fiber particles are needed for normal cecal-colonic motility (Cheeke,1994)
兔子饲料不宜过于精细,太精细,太小的营养颗粒,将减少肠道蠕动,同时引起肠炎,对此,大的难消化的纤维对于兔子肠道蠕动功能是必须的.
