Toxicity of Urea to Sheep

Toxicity of Urea to Sheep

IT is generally accepted that urea is toxic when fed at levels greater than 30–35 gm. per sheep a day. Clark et al. 1 produced toxic effects by drenching sheep with 10 gm. of urea. Peirce et al. 2 killed many sheep when they fed 25–45 gm. of urea per sheep a day; in this experiment, the daily ration...

Zusammenfassung:IT is generally accepted that urea is toxic when fed at levels greater than 30–35 gm. per sheep a day. Clark et al. 1 produced toxic effects by drenching sheep with 10 gm. of urea. Peirce et al. 2 killed many sheep when they fed 25–45 gm. of urea per sheep a day; in this experiment, the daily ration of urea was consumed over a period of approximately 1 hr. By adjusting the method of feeding, we have found it possible to feed sheep up to 100 gm. of urea a day with no mortality.
