  • * Excluded from summary statistics and correlation analysis (see below and text).

  • Calculated from the absolute residual values.

  • a Minimum lipid content refers to the lowest predicted lipid content observed.

  • b Number of days after departure and weaning at which minimum drift rate occurred.

  • c The difference between the actual and predicted lipid content.
