Summary
One hundred forty-four steer calves were fed growing diets that contained either 1) 50% ground alfalfa hay (ALF), 2) 25% ground alfalfa hay and 25% ground, ammoniated oat hulls (ALF/GOH), 3) 50% ground, ammoniated oat hulls (GOH) or 4) 50% unground, ammoniated oat hulls (UGOH). Oat hulls were treated with ammonia at 3.3% by weight and enough water to raise the moisture content to approximately 20%. They were allowed to react for 32 days prior to feeding. Daily gains were greater for calves consuming the ammoniated oat hull diets, regardless of form (P<.10). Daily gain differences occurred in spite of the fact that dry matter intake was lower for GOH-fed calves than for the others (P<.10). As a result, feed efficiency was better for the GOH diet than ALF and ALFIGOH (P<.10) but did not differ from UGOH (P>.10). Ammoniated oat hulls, whether ground or unground, are a viable substitute for more conventional roughages in feedlot growing diets.
