Does it Matter?

Milk:

  • Volume

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!
