higher levels of bypass protein within meals may be helpful in the diets of lightweight lambs,protein requirements of larger and older lambs are usually met by cereal grain and pulses.Urea is a cheap form of non protein nitrogen that the rumen microbes are able to turn into protein for the lambs use.Urea can be included usually at 1-2% dry matter (dm),to raise the crude protein(cp) content of the ration.In the process of conversion into protein, urea is temporarily converted to ammonia by rumen microbes.A sudden surge of rumen ammonia can be fatal,so it is important that urea is evenly mixed in the ration and its concentration slowly increased over 7-10 days during introduction.A mix all ,is one method of incorporating urea.One can spray a 50% urea solution evenly onto the feed,means dissolving 10 kg. of urea to 20 Litres of water to treat 1 ton of dry matter of ration.Urea should not contribute more than 25% of a rations total crude protein content.Small lambs 30 kg.and under should not be fed rations containing urea,as their rumens are not yet fully functional supplies. We mix urea in our goats drinkling water,small amount only,too much will poison your goat(s).
