Ten experiment stations in the Northeast have cooperated in investigating three sources of amino acids (pure amino acids, milk protein and wheat gluten) at two levels (1.2% and 1.6% dietary nitrogen) with different subjects (humans, rats, pigs and protozoa) under different conditions (growth, maintenance and stress) in order to study availability of amino acids in protein. The publication describes the effect of the three nitrogen sources containing equal amounts of essential amino acids and nitrogen on the growth of rats over two and four weeks.
