Does it matter

Does it Matter?

Milk:

  • Volume

  • Components

  • MUN

    Reproduction

    Health

    & …


Feed conversion efficiency

Feed Conversion Efficiency

  • FCE = Energy Corrected Milk / Dry Matter Intake

  • Energy Corrected Milk (ECM) = Milk kg Corrected for 4.4 % Fat & 3.3 % Protein

  • What Should FCE Be?

    < 1.2 is poor

    1.2 – 1.4 is good

    > 1.4 is the goal

Feed sampling analysis

Feed Sampling & Analysis

Method of Sampling?

  • Multiple samples, mixed & sub-sampled

  • Core samples of 10 bales

    Frequency of Sampling?

  • More variable, more samples

    Analysis

  • Wet Chemistry

  • NIR


Dry matter variation

Dry Matter Variation

Corn Silage

Variation of DM

  • % Forage

  • % Forage NDF

  • % Starch

  • Variation of % Grain

    • Switch Corn Silage for Ground Corn (DM basis) & Vice Versa.

    • Changes % Starch, not Protein


  • Analytical ration formulation i

    Analytical Ration Formulation I

    Who do we formulate for?

    • Milk Cow: 2-yr old, 90 DIM, peak milk

    • Others incl. dry, close-up & heifer

      Accurate Analysis of Feeds

      Biological Model – CNCPS v6.1

      Ration Balancing Software:

    • AMTS vs. CPM


    Analytical ration formulation ii

    Analytical Ration Formulation II

    Prefer High Forage Ration

    Available & Digestible

    Crude Protein

    vs. Amino Acids

    Maximize Rumen Function

    Starch vs. Sugar

    vs. Soluble Fiber

    Rumen Degradable vs. Soluble

    vs. Bypass Protein

    Fats


    Custom concentrate

    “ Custom Concentrate”

    Concentrate is Formulated “Around” Available Forages


    Feed additives

    Feed Additives

    Energy Booster®

    • By-pass (rumen inert) fat supplement that contains saturated fatty acids

    • Increases energy density of the ration to promote milk production and body condition while maintaining DMI

    RuMin8®

    • Contains soluble sugars, mineral salts and organic acids

    • Increases milk production by providing energy and VFA production

    • Provides more complete digestion by matching protein and carbohydrate sources


    Physical ration formulation

    Physical Ration Formulation

    To Promote a Healthy Rumen Mat

    • Sufficient Long Dry Fibers

    • Consistently

    • 6 to 8 cm in Length

      Wetting of Concentrate

    • Changes Physical

      Property in Rumen

    Field Results

    The Keenan System

    1,100 Farms & Over 80,000 Cows Using

    the System Have Seen:

    • 12% increase in feed conversion efficiency

    • 2.2% decrease in DMI

    • 7.8% increase in milk production (ECM)

    • An improvement in margin (Profitability)

    You hungry?

    If they mixed it right!


    So which ration is it

    So Which Ration Is It?

    1) Ration on Paper

    2) Ration Mixed

    3) Ration Delivered

    4) Ration Consumed

    5) Ration digested


    The answer is easy

    The Answer is Easy!

    They Should All Be the Same!


    Reading feed bunks

    “Reading” Feed Bunks

    • Amount of Feed Left after 24 hrs Feeding

      • Orts, Weighback, PushOut

    • Measure at the Same Time Every Day & Adjust Amount Fed for Next Feedings

    • “Perfect” ???

      • 5%

      • 2%

      • 0%

    Three things cows need to do

    Three Things Cows NEED to Do!

    • Stand - Eat & Drink

    • Stand - Milking

    • LAY DOWN,

      Ruminate &

      Make Milk!
