EnerGII Research – Virtus Nutrition

Research Review

Twenty plus years of EnerGII being fed to dairy cows… let’s take a look back at the research results.

More Milk & Milk Fat with Better Fatty Acid Balance

Increase in Milk Per Day

When compared to a ‘no added fat’ control diet, EnerGII consistently yields more milk.

Increase in Milk Fat

Most recent studies show an increase in milk fat as EnerGII adds more Palmitic Acid, often replacing some unprotected 18:2 source, such as distiller’s grain.

It’s All About Efficiency

Better FCM / Dry Matter Intake Ratio

Due to the impact of Oleic on increasing digestibility, EnerGII yields higher FCM with the same or lower intake.

Higher Feed Efficiency

More fat corrected milk with the same or less intake means a more efficient herd.

Better Body Condition

EnerGII gives cows more energy to use wherever they need it most, including replenishing body condition.

The Why Behind the Results

The Profile of EnerGII – 50% Palmitic & 35% Oleic

Consistent Since 1996!

50% Palmitic

It is well established* that Palmitic supports milkfat, and to a greater extent than milk flow.
Balance is key as milkfat is not the only goal.

*Steele and Moore, 1968; Noble, 1969; Steele, 1969; Mosley, 2007; Warnjes, 2008; Rico, 2011; Lock, 2013; Piantoni, 2013

35% Oleic

Oleic acid enhances the digestibility of all fatty acids via micelle formation**, supporting milk flow, reproduction and body condition replenishment.
