Abstract:
A concentrated controlled release non protein nitrogen ruminant feed supplement composition which releases nitrogen in rumen fluids at about the same rate that the nitrogen metabolizes therein, the composition comprising:(a) central particles of rumen-fluid-degradable nitrogen compounds, exhibiting diameters between 0.5 and 4.0 millimeters, and containing between 20 and 46 percent nitrogen; and, (b) non-rumen-fluid-degradable semipermeable membranes coatingly covering the central particles in an amount sufficient to allow substantially complete diffusion of the rumen-fluid-degradable nitrogen compound of the central particles through the semipermeable membranes into the rumen fluid in a period of time between 6 and 24 hours.
