Effects of Different Levels of Dry-Rolled Corn or Barley on the Utilization of Medium Quality Meadow Hay with Steers and Performance with Heifers
|
Abstract
In Trial 1, five Angus-Gelbvieh cross-bred steers (BW = 295 ± 3 kg) fitted with rumen cannulas were used in a 5 à 5 Latin square design to determine intake and digestibility of medium-quality native grass hay (9.5% CP) when supplemented with 0.25% BW dry-rolled corn (low corn; LC), 0.50% BW dry-rolled corn (high corn; HC), 0.25% BW dry-rolled barley (low barley; LB), 0.50% dry-rolled barley (high barley; HB), or when receiving no supplement (NS). Forage DMI decreased with in...
