Unsaturated lipid-enriched feedstock for ruminants
First Claim
1. A supplemented feedstock adapted for beneficial feeding of a ruminant, which feedstock comprises (1) nutritionally balanced ration;
- (2) between about 2-20 weight percent, on a dry matter basis, of lipid ingredient comprising unsaturated fatty acid derivative having rumen-bypass properties; and
(3) an effective quantity of cyclic polyether ionophorous antibiotic ingredient;
wherein a ruminant feeding regimen with the feedstock induces an increased production of propionate in the rumen, and a resultant improved feed efficiency and body growth in the ruminant.

Abstract
This invention provides a feedstock for ruminants which beneficially improves feed efficiency and body growth. The feedstock also is adapted to improve the lactational performance of dairy cattle. The recovered milk product has a milk fat profile with an increased proportion of unsaturated fatty acid constituents. The enhanced benefits exhibited by an invention feedstock are derived from essential ingredients such as unsaturated fatty acid derivative having rumen-bypass properties, and an effective additive quantity of cyclic polyether ionophorous antibiotic.
