Feeding Fat (Part 2)

Feeding palm fats

  • Feeding rumen protected fat or bypass fat is not new.

  • It is common for dairy farms to work towards increasing energy in high producing cows to support production.

  • Commercial bypass fat made of palm oil has been increasingly popular as it helps to increase butterfat milk of 0.2 - 0.4%.

  • Milkfat is made up of different types of fatty acids.

  • About 50% of milkfat composition comes from short chain fatty acids (up to 16 carbon fatty acids chain).

  • The rest of it comes from fatty acids which have been absorbed directly from the blood stream.

  • Compared to synthesized fats, blood borne sources of fatty acids in milkfat are primarily made up for longer 16- to 1 8-carbon fatty acids.

  • Hence, rumen bypass fats from palm oil is the default choice to use to raise milkfat as it contains high C16.

  • Processed palmfat has high melting point - around 135ºF.

  • It also easily bypasses the rumen and is digested in the small intestine of the dairy cow.

  • C16:0 fatty acid chains are absorbed into the bloodstream and transported to and then drawn off by the udder and synthesized into milkfat.

  • Regardless of what type of palm fat supplement is added to the ration, make sure to avoid overfeeding it.

  • Palm fat should complement the rest of the dairy ration instead of just focusing on raising milkfat yield.
