Abstract
Branched chain fatty acids and valeric acid (isoacids) are either required by, or stimulate growth of, many rumen organisms and are required for cellulose digestion. Added isoacids provide a carbon skeleton for synthesis of branched chain amino acids valine, leucine, and isoleucine. Isoacids may stimulate bacterial protein synthesis, increase nitrogen retention, and enhance cellulose digestion. In lactating dairy cattle, addition of isoacids to the diet has the potential to increase milk production by 5 to 10%. This response may not occur under all dietary and management conditions, and may differ according to age of cows. The improved response occurs primarily in early lactation. Results with the addition of isoacids to diets of growing animals have been promising and warrant additional studies.Keywords
