<p>To improve the efficiency of utilization of protein by ruminant animals when fed as part of a complete balanced diet, a mixture containing protein and a reducing carbohydrate, at or adjusted to a suitable pH and moisture content, is subjected to heat, pressure and shear forces followed by post conditioning, which involves regulation of the temperature of the mixture over various time periods. Heat pressure and shear forces may be applied by processing material through a cooker-extruder or expander. Protein so processed can be substantially protected from ruminal degradation without markedly reducing its subsequent absorption in the lower digestive tract.</p> |
