... Although the principal claimed benefits of these products over earlier mixtures are assumed to be improved efficiency and greater utilization of ureanitrogen via slower-released ammonia from diets fed twice daily, this assumption may not be entirely valid based upon recent research results such as those by Knight and Owens (1973)

... Despite these recent trials, greater palatability and increased energy intake resulting from the use of any new type of urea product would be a useful feature in ruminant diets, especially in the high-producing cow, young growing calf and lamb, and feedlot cattle and lambs starting on feed when energy consumption is lowest. The future prospect of these new NPN- or urea-carbohydrate combinations being as beneficial as oilmeals in supplements incorporated into cattle and sheep diets would appear to be better when the diet contains less natural protein than about 13 percent of its dry matter content.

... . Indeed, in vivo digestion trials have shown that ammoniated molasses is of limited value as protein replacement in ruminant diets (Tillman and Swift, 1953; Tillman et al., 1955, 1957a,b;Kinge/a/., 1957)

... . Ammoniated beet pulp and citrus pulp, containing no more than 20 percent crude protein equivalent, can be fed to beef cattle and dairy cattle in diets containing some concentrate and no more than 30-40 percent ammoniated pulp without adversely affecting intake or performance (Connell et al, 1944; Davis et al., 1946, 1952; McCall and Graham, 1953)

... Variations in reports about adaptation periods to biuret appear to be related to the nitrogen status of the experimental animals and the level of protein in the basal diet to which biuret was added. The adaptation period may be shortened by the addition of readily available energy to a lowprotein diet (Gilchrist et al, 1968)

... Clemens and Johnson (1973) reported that sheep fed poor-quality hay free choice plus biuret at 4-day intervals could not maintain rumen biuretolytic activity compared to feeding biuret at 1 - or 2-day intervals.

... The major condensation products of urea are biuret and cyanuric acid. Biuret, in basic metabolism and practical feeding trials, offers much promise as a nitrogen supplement for ruminants consuming lowprotein roughages supplemented intermittently.
