^a–dWithin a row, means with differing superscripts differ (P < 0.05). The linear model used included block (BW), treatment, and block × treatment to evaluate the difference among five treatments, P value is not shown.

^x,yWithin a column, means with differing superscripts differ (P < 0.05).

¹Control diet contains 6.0% soybean oil; encapsulated palm oil (granular, containing 80% palm oil), encapsulated coconut oil (granular, containing 80% coconut oil).

²SEM is for treatment within the same row.

³Palm oil vs. coconut oil.

⁴Encapsulation vs. not.

⁵SEM is for different weeks within a treatment in the same column.

⁶ P value is for among weeks within a treatment in the same column.
