What causes foaming at the mouth?
Foaming at the mouth is a sign of sham chewing (stereotypical behaviour). The sow isn't (or wasn't) feeling well. Stereotypical behaviour is comforting to the animals due to the release of morphine-like substances.Once they start, they keep doing it.If many sows in the pen are sham chewing,look for the cause. Does the feed provide a satisfied feeling? Are they waiting to be fed at the feeding station? Is something wrong with the climate? Are the sows unable to flee from a dominant sow? Do they have enough lying space?
这是老外对这种“空嚼”现象的看法。翻译如下:
什么原来引起嘴里这么多的泡沫呢?
嘴里泡沫是空嚼的特征(模式化机械的行为)。母猪感觉不好。这种机械的行为的产生是因为吗啡样物质在体内释放的结果。一旦开始,行为就持续下去。如果有一头母猪发生空嚼现象,就必须要找原因,是不是饲料不能满足?是不是她们在等着喂料?是不是气候影响的?是不是母猪没办法逃避具有统治地位的母猪?是不是母猪没有足够的地方躺下?
