什么草有毒常见的图片(细数几种有毒的牧草品种?该怎么避免中毒?这3种一定要注意)

牛羊吃百草,草食量也非常大,草食家畜既优良、又经济的饲料作物。每个牧草其实也都有自己的优缺点,那么,之前我们有细谈过每个牧草的优点,今天就来细数下以下几种牧草的缺点,避免在饲喂过程中引起负面作用。

一、串叶松香草:

串叶松香草是一种高产多年生牧草品种,耐寒高温,抗逆性强,南北方都可以种植,营养价值也非常高。据测定,串叶松香草含有三萜类化合物,所以存在了一定的生物碱,这类毒素主要会损害猪的肝脏和肾脏,长期饲喂会造成积累性中毒。

因此,应将饲喂量控制在日粮的30%以内,最好同其它青饲料搭配使用,这样是非常安全的。


二、俄罗斯饲料菜:

俄罗斯饲料菜高产耐寒耐热,多年生牧草,南北方都可以种植。据测定,俄罗斯饲料菜是一种含有生物碱,这是一种危害肝脏的有毒物质,如果作为饲料饲喂过多,会在家畜体内产生积累性中毒,并危及人体肝脏。聚合草的饲喂量应控制在日粮的25%,也尽量要同其它牧草搭配和交叉饲喂。

注意:只要一头猪不要常年饲喂一种俄罗斯饲料菜,都是不会造成中毒现象的。

三、苏丹草:

苏丹草为高粱属植物,一年生禾本科作物,茎叶柔嫩多汁,耐高温、耐干旱,但不耐寒。茎叶中含有氢氰酸,其毒性较强,可致家畜死亡。如果是家畜饲喂中毒发病后应立即用亚硝酸钠1克、硫代硫酸钠2.5克、注射用水50毫升,混匀后静脉注射。

另外,高粱苗、玉米苗等也含有较多的氰甙,家畜采食后,氰甙也会转化为氢氰酸。因此,使用这类作物作饲料时,最好能将其调成青贮饲料、干草,或收割后进行晾晒一下,氢氰酸挥发之后再进行饲喂,降低其中的毒素含量,减弱其毒性,以免引起家畜中毒。

大家在平时饲喂牲畜以及家禽是,需要特别留意,千万不能大意
