1) Fluid bed process FBPT

2) Spray congealing SCT

3) Solid dispersion SDT.

Dissolution percentage (in rumen mimic solution) of rumen protected methionine products encapsulated by fluid bed process technology kept at 90 °C for 30 sec, 60 sec, 120 sec varied from 2.44%-10.08%, those encapsulated by spray congealing techniques varied from 6.38%-32.46% while those manufactured by solid dispersion technique varied from 31.32%-78.2%. Dissolution percentage (in rumen mimic solution) of rumen protected lysine products encapsulated by fluid bed process technology kept at 90 °C for 30 sec, 60 sec, 120 sec varied from 3.2%-6.6%, those encapsulated by spray congealing techniques varied from 9.04%-29.41% while those manufactured by solid dispersion technique varied from 36.45%-83.47%. Results from study indicated that release of amino-acids in rumen mimic solution coated with same type of coating agents depends on type of technology employed. Products coated using fluid bed top-spray process technology had lowest coating degradation in rumen mimic solution and thus highest rumen bypass efficacy while products coated with solid dispersion technology had high coating degradation in rumen mimic solution and thus lowest rumen bypass efficacy.
