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

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

Feed Additives

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

To Promote a Healthy Rumen Mat Sufficient Long Dry Fibers Consistently 6 to 8 cm in Length

Wetting of Concentrate Changes Physical

Field Results1,100 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)
