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
