  冬天即将结束,一些马主可能是看到干草供应减少,好消息是主人可以用其他纤维资源补充马匹的饲料。

  无论是品种还是预期用途,所有的马都需要膳食纤维。 大量证据表明,足够的膳食纤维可导致多种消化系统问题(如绞痛)和行为恶习。马的纤维需求最常见的是牧草,但如果没有这些来源,马主人必须找到替代纤维的选择。一些常见的替代品包括干草方块、饲料和纤维副产品。

  干草方块是一个很好的纤维来源,通常很容易在大多数饲料店买到。对比干草 使用干草方块两个主要好处是:

  1)干草方块通常含有比干草少的灰尘,这意味着马不受吸入颗粒的影响,而这些颗粒可能导致呼吸系统疾病;

  2)使用干草方块通常会减少饲料浪费相比干草。

  大多数马会比干草消耗更多的干草方块,所以主人应该测量和监控马匹的摄入量。干草方块可以和干草一起,以1:1的比例 。例如,如果一匹马在每次喂食时消耗五磅的干草,用五磅的干草方块代替,并根据体重适当调整草量。干草方块重量较重,所以你需要称量它们以确保马得到适当数量的饲料。

  完整的饲料配方,以提供一个适当的营养需求,包括纤维,并很通过大多数马饲料制造商那里获取。完整的饲料通常含有超过16%的粗纤维,并且与较低的纤维谷物混合饲料相比,有更少量的干草。因此,也可以一天提供几顿小餐点。对于成品的马粮饲料,注意观察包装上的标签是很重要的,以确保马匹能够获得足够的营养,纤维和其他饲料成分。

  纤维副产品来源包括甜菜浆、麦麸和谷物壳。甜菜制糖生产的甜菜浆,因其具有良好的消化能力和适口性,深受喜爱。研究表明,马的饮食中可以含有多达55%的甜菜浆而不会产生负面影响。重要的是要记住,甜菜浆的消化率高于大多数牧草,在切换食物配方时需要合理调配 。

  麸,如米糠、麦麸,是另一种选择,但往往是不可取的由于其高磷浓度。如果喂麦麸,确保马匹摄入足够的钙以保持钙:磷的比例至少为1:1。另外,要记住米糠含有高脂肪,因此不应用于超重或肥胖的马匹。

  燕麦壳也是高纤维,但往往灰尘较多,喂食前应与水混合。

  由于这些纤维的副产品只可发酵纤维的来源,应该伴着干草喂食或者其他完整的纤维源。因此,这些来源应该用来辅助干草而不是代替干草。
