Abstract: The use of SAA/MAA levels in mammalian fluids to develop management strategies that maximize sustainability, mammalian health, productivity, and economic return including for example the formulation of cost effective nutritional management strategies, determining whether an individual mammal should be retained in a herd or culled, determining the value of the individual mammal as a contributor of genetic material for herd replacement, determining a course of immediate and/or prophylactic health care intervention, etc.

Abstract: A composition, and method of use, for controlling, reducing or preventing the growth of protozoal bacteria in the ruman of a rumiant comprising cell bodies of a facultative anaerobe selected from the group consisting of Corynebacterium cell bodies and Brevibacterium cell bodies or a mixture of Corynebacterium cell bodies and Brevibacterium cell bodies, glutamic acid fermention solubles, corn fermentation solubles, glutamic acid fermentation solubles and corn fermentation solubles.

Abstract: This invention provides a feed additive for ruminant and other animals, as well as pork and poultry, that includes a balance between positively charged particles and negatively charged particles, to cause the diet to have a negative cation/anion balance. The composition may be obtained from either glutamic acid fermentation solubles, corn fermentation solubles, or other related fermentation solubles, or a mixture thereof. The composition enhances ionic activity through the addition of ionic sources such as ammonium or magnesium salts, and related salts, which together function as a feed additive to increase meat tenderness.
