Notes.

DHA intake: reported in the article or calculation: dry matter intake × fatty content of dietDHA content.

Fatty acid ≈ triacylglycerols + diacylglycerols + monoacylglycerols + free fatty acids.

Milk fatty acid = milk fat content × 99.13% (MacGibbon & Taylor, 2006).

Milk DHA yield: reported in the article or calculation: milk fatty yieldDHA content.

Efficiency: milk DHA/diet DHA.
