Boost is an energy supplement made from pure fatty-acid product obtained by fractionation of palm fat. The fatty acids are split off specifically from the fat molecules and sprayed to form a dry, free-flowing fat powder

What Is Boost?

  • This makes it resistant to fast oxidation and spoilage.
  • It also has a high melting point of 58ºC.

Trial Test Results
  • For comparison with the zero control, 2% PureBoost (percentage of the dry feed weight) were added as a supplement.
  • As a result of this supplementation the fat content of the milk increased from 3.88% to 4.18%.
  • This represents a highly significant increase in the quantity of milk fat from 1.23 kg to 1.33 kg per cow and day.
  • Correspondingly the milk quantity, 3.5% FCM, also increased significantly by 1.7 kg per day

Economic evaluation of the use of PureBoost in US $
  • The table shows a comparison between control and PureBoostWith the addition of 2% PureBoost to the dry feed, the production of FCM was higher with PureBoost.


  • This also shows that although the feed uptake of the PureBoost group was lower than in the control group, PureBoost enables the cows to meet their energy requirements with a smaller feed uptake. 

  • The economic evaluation of the trial on the basis of prices at the time of the trial shows that the addition of PureBoost offers a definite economic benefit.

  • In order to verify these results, a second trial was carried out with identical usage levels (2% PureBoost). This led to significantly higher values for PureBoost with 4% more milk, 3% more FCM, 3% more ECM and 3% more protein.
