Maximum Replacement of Protein by Urea in the Ration of Milch Animals

It is a known fact that there is a very acute shortage of feeds for our animals. Whatever we have to feed them, is severely deficient in protein. This has competed people to find out new sources both for supplying of enough feeds and also enough protein. Cullison, Davis et al, woodward and Shephard, Mitchell et al Bently et al Tiborne and Johnson et al carried out work to study the utilization of urea, ammonia and other nitrogen sources by farm animals, by mixing these in silage.
