Energy Status of Steers Dictates Effectiveness of Glycerol Inclusion in High-Roughage and High-Concentrate Feedlot Diets

<p>The objective of this research was to determine how to use glycerol as an effective source of energy in ruminant diets. Steer calves were used in a 56 d backgrounding study (n=128; Initial BW=340 ± 15 kg) and 105 d finishing study (n=120; Initial BW=420 ± 20 kg). Dietary treatments during backgrounding included 0, 8, 16, and 24% glycerol replacing corn silage in corn silage-based diets. Steers continued on within relative levels of dietary glycerol with finishing diets consisting of 0, 5, 10, and 15% glycerol replacing corn. Cumulative DMI, ADG, and G:F increased linearly (P</p>
