6. Tell the story:Remind the stakeholders of what we found with DOM from 2015Remind them that we only presented CP in Sept 2016 meeting, and we forgotto present the DOM data.We would like to present the DOM and CP data to them now, and discuss whatwe can learn from themShow loamy vs. sandy DOM and CP first.
7. Loamy vs. Sandy fecal crude protein (%) 2016Stairsteps of dietary crude protein over grazing season.Most of the season:Loamy > SandyVery high animal gainsGood animal gainsMarginal animal gains
8. Loamy vs. Sandy fecal DOM (%) 2016Similar stairsteps of dietary DOM over grazing season.BUTMost of the season:Sandy > Loamy
9. Diet Quality Insights from 2016:DOM (Digestible Organic Matter): Sandy > LoamyCP (Crude Protein): Loamy > SandyWhich one predicts growing-season cattle weight gains?Actual 2016 cattle gains: Sandy (2.1) > Loamy (1.9)Implication: DOM is important indicator for growing-season cattle weight gains
