Management and nutritional quality of tall fescue and alfalfa grown in combination, compared to tall fescue fertilized with nitrogen
… Fe from stockpiled forages were determined in a dacron bag study in 1992-93. In 1991-92, stockpiled N-fertilized fescue improved steer performance over stockpiled fescue-alfalfa (P<0.05); in 1992-93, this result was reversed (P<0.05) due to forage availability. Blood urea nitrogen was higher …
