    • Managing $5, $6, $7 bu corn DAIReXNET Dairy Webinar
    • $20 milk in 2004 is not $20 milk in 2008
      • Hay prices varying from $200-$275 a ton
      • Corn silage at $50 to 60 a ton
      • Corn grain at $5 to $8 / bushel
      • Breakeven milk prices have reached a new level ($16-$18 per cwt in Illinois)
      • It’s a new dairy game; we need to adjust!
    • Today’s Program
      • Monitoring feed costs in 2008
      • Strategies with high corn/barley prices
      • Other management aspects
    •  
    • Point 1 Monitoring Feed Costs
    • Feed Costs 101
      • lb DM $/ lb DM $ / day
      • Forages 28 .10 2.80
      • Grain energy 10 .10 1.00
      • By-product 6 .15 0.90
      • Protein supp 5 .15 0.75
      • Min/vit/additive 1 .35 0.35
      • Consulting 0.10
      • Total 50 5.90
    • Feeding Economics
      • Feed costs per cow per day $5.90
      • Feed cost per lb DM $0.118
      • Feed cost per cwt (80 lb) $7.38 (80 lb) $8.42 (70 lb)
      • Income over feed costs ($18) $10.62
      • Feed efficiency (lb milk/lb DM) 1.60 (80 lb)
            • 1.40 (70 lb)
    • Economics of Feed Efficiency (70 lb milk, 12 cent lb DM)
      • Feed efficiency DMI Difference
      • (lb milk/lb DM) (lb/day) (savings/day)
      • 1.20 58.3
      • 99 cent
      • 1.40 50.0
      • 74 cent
      • 1.60 43.8
      • 59 cents
      • 1.80 38.9
    • Using the 55-15-30 Rule
      • 55% of the ration is forage dry matter
        • 28 lb of dry matter
      • 15% of the ration is yours call
        • 7.5 lb “swing” dry matter room
        • Forage quality
        • Economics of by-products
        • Cheaper nutrient sources
      • 30% of the ration is concentrate
        • 15 lb of dry matter (energy, protein, VM pack)
    • Feed Economics
      • Dry matter intake vs. milk price
        • 2 pounds of milk per pound of DMI
        • 40 to 44 cents income vs. 12 cents expense
      • Comparison of forages vs. grain vs. fat
        • Corn silage ($60/t) = 12.5 cents per Mcal
        • Corn grain ($7/bu) = 20.3 cents per Mcal
        • Oil (49 cents/lb) = 21.8 cents per Mcal
    • Take Messages (Point 1)
      • Calculate basic feed costs
        • Cost per lb of DM (< 11 cents per lb)
        • Feed costs per cwt milk (< $7.00)
        • Feed efficiency (> 1.5 lb milk/lb DM)
        • Income over feed cost (> $10.00/cwt)
      • Compare to local values in your area
      • Are alternatives available (55/15/30)?
      • Avoid “bad” economic decisions
    • Point 2 Strategies with Expensive Corn/Barley
    • Rumen Fermentable Carbohydrates—The Key
      • Starch (corn or barley): 20 to 26%
      • Sugar (molasses or whey): 4 to 7%
      • Digestible/fermentable fiber (beet pulp or citrus pulp): 10 to 14%
    • Alternative Starch Sources (Source: AminoCow Feed Library)
            • Starch Sugar Sol Fiber
            • ------------------------%----------------------
      • Wheat 64 2 3
      • Barley 58 2 3
      • Whey 0 69 0
      • Molasses 0 61 0
      • Bakery waste 45 8 2
      • Corn distillers 3 4 8
      • Corn gluten 20 2 3
      • Hominy 49 4 2
      • Wheat midds 22 5 6
      • Beet pulp 1 8-20 21
      • Citrus pulp 2 24 34
    • Lower Starch Levels
      • Recommended levels: 20 to 26%
      • Rumen fermentable carbohydrates
          • Feeding high quality forage
          • By-product by-product feeds
          • Consider starch availability in the rumen
      • Addition of Rumensin (1 to 2 lb corn equivalent at 300 mg/day)
      • Reduce fecal starch losses
    • University of Florida
    • Shelled Corn Energy Values (Dairy NRC 1989) 0.96 Finely ground (1100 micron) 0.94 High lysine (floury) 0.93 Steam flaked (24/25 lb bu) 0.93 High moisture (>26%) 0.89 Ground (1500 micron) 0.84 Cracked (2200 micron) Mcal/lb DM
    • Coarsely ground grain in manure University of Florida
    • Take Home Message (Point 2)
      • Consider all sources of rumen fermentable carbohydrates
      • Optimize feed processing to make nutrients available
    • Point 3 Other Managements Aspects
    • Management Factors
      • Target MUN values between 10 to 14 mg/dl (low fermentable carbohydrates can raise herd values)
      • Consider more than one TMR group
        • Save $1.25 per cow per day
        • Lower dry matter intake saves 60 to 75 cents
        • Moving cows can drop milk 0 to 5 lb per cow
      • Increase corn silage levels (can lower feed costs 25 to 40 cents per cow based on current IL feed prices).
