| 英文描述 | The addition of anhydrous ammonia to molasses, hay, and silage has led to excitability ('bovine bonkers', 'bovine hysteria') in cattle eating those feeds and in calves nursing those cows. This syndrome has also been reported to occur in sheep and goats. There is generally a source of ammonia, carbohydrates, moisture, heat, and an alkaline pH in feedstuffs which are associated with this syndrome. Contamination of water by liquid nitrogenous fertilizer has also caused toxicity. Another form of toxicity is due to direct chemical irritation of the cornea following exposure to fertilizer containing anhydrous ammonia. Dx by exposure history. |
