Abstract:
... There has been increased interest in using switchgrass (Panicum virgatum) as a biomass crop. There are several challenges to developing this industry, and these have led to the potential use of switchgrass as hay for feeding beef cattle in Kentucky. The effect of increasing maturity on concentrations of CP, NDF, ADF, and other nutritive value indicators of switchgrass hay is well documented, but f ...

Fourteen organic dairy farms in the northeastern United States were used to evaluate (1) seasonal variation in bioactive milk fatty acid (FA) profile from 2012 to 2015 and (2) supplementation of ground whole flaxseed (GFLX) to maintain elevated concentrations of bioactive milk FA during the nongrazing season. During regular farm visits, milk, feed, and pasture samples were collected, and diet comp ...
