Abstract
Abstract A livestock feed silage composition composed of brewers wet grain, mineral supplements and a carbohydrate source such as dry feed grains. The feed silage composition may also include, in addition, brewers autolyzed yeast and/or roughage. The brewers wet grain used in the silage composition is to have some of its moisture removed prior to blending with the other ingredients, so that the blended silage composition has a moisture content in the range of 35 to 58 percent by weight. The silage composition is fermented under essentially anaerobic conditions and in a controlled manner due to the presence of the mineral supplement which not only supplies essential nutrient balance to the silage composition, but provides also a buffering action during fermentation which controls the pH of the fermented silage feed mixture in the range of 4.0 to 4.5. This imparts good keeping quality to the silage composition and provides improved palatability to the resulting fermented mixture which may be used by itself or with other nutrients and feed materials as a livestock feed.

Claims Analysis
Total Claims: 12
Claim 1
Independent Claim
193 words
A METHOD OF PREPARING A LIVESTOCK FEED COMPOSITION COMPRISING THE STEPS OF, REDUCING THE MOISTURE CONTENT OF BREWER''S WET GRAIN HAVING A MOISTURE CONTENT OF OVER 80 PERCENT BY WEIGHT TO A VALUE OF BELOW 70 PERCENT BY WEIGHT, INTIMATELY MIXING THE BREWER7S WET GRAIN OF THE REDUCED MOISTURE CONTENT, A HIGH-CARBOHYDRATE LIVESTOCK FEED MATERIAL AND A MINERAL SUPPLEMENT CONTAINING BUFFERING COMPOUNDS TO PROVIDE A BLEND HAVING A MOISTURE CONTENT OF 35 PERCENT TO ABOUT 85 PERCENT BY WEIGHT SAID BLEND CONTAINING ON A DRY BASIS FROM 12 TO 70 PERCENT BY WEIGHT OF SAID BREWER''S WET GRAIN, 25 TO 80 PERCENT BY WEIGHT OF SAID CARBOHYDRATE FEED MATERIAL AND 1 TO 5 PERCENT BY WEIGHT OF SAID MINERAL SUPPLEMENT AND HAVING A PROTEIN CONTENT ABOVE 10 PERCENT BY WEIGHT ON A DRY BASIS FERMENTING THE BLEND UNDER SUBSTANTIALLY ANAEROBIC CONDITIONS TO PROVIDE A FERMENTED SILAGE; AND BUFFERING THE PH OF THE SLIAGE THROUGH THE ACTION OF THE BUFFERING COMPOUNDS IN THE MINERAL SUPPLEMENT DURING FERMENTATION SO THAT THE SILAGE HAS A PH IN THE RANGE OF 4.0 TO 4.5, SAID SILAGE HAVIN IMPROVED PALATABILITY TO THE LIVESTOCK AND INCREASED STABILITY AGAINST SPOILAGE.
