Abstract
Twelve Holstein steers (340±7.2 kg) with cannulas in the rumen and proximal duodenum were used to study the influence of fat titer (36 vs. 41°C) and method of fat inclusion (mixed in a portion of steam flaked corn in the proportion 25% fat and 75% corn, prior to adding other ingredients vs. addition of fat to the mixer as the second-to-last step, just before adding molasses) on characteristics of digestion. The basal diet contained 74.4% steam-flaked corn and 5% supplemental fat. There were no treatment effects (p>0.10) on site and extent of OM, starch, N, lipid and ADF digestion, nor on ruminal VFA molar concentrations. Post-ruminal lipid digestion averaged 69.3%, in close agreement with expected (71%; where fat digestion, % = 83.18-4.52FI-0.68FI3) based on level of fat intake (FI, g kg 1 of body weight).
