¹Control diet contains 6.0% soybean oil; encapsulated palm oil and encapsulated coconut oil (containing 80% ether extract) were produced by combing palm oil or coconut oil with dried casein and whey powder in a spray-drying process causing the milk proteins to encapsulate the fat particles as they dried. Dried casein and whey powder were obtained from the same source, other treatment diets without encapsulated fat contained identical amounts of casein and whey.

²Provided the following amounts of vitamins per kilogram of diet: vitamin A, 12,000 IU as retinyl acetate; vitamin D3, 3,600 IU as cholecalciferol; vitamin E, 150 IU as DL-α-tocopherol acetate; vitamin K3, 7.2 mg as menadione; thiamine, 3 mg; riboflavin, 10.8 mg; pyridoxine, 5.4 mg; vitamin B12, 0.06 mg; pantothenic acid, 36.0 mg; niacin, 60.0 mg; folic acid, 6 mg; biotin, 0.6 mg.

³Provided the following amounts of trace minerals per kilogram of diet: Cu, 10 mg as CuSO₄.5H₂O; Fe, 39 mg as FeSO₄. H₂O; Mn, 30 mg as MnSO₄; Zn, 39 mg as ZnSO₄; Se, 0.15 mg as Na₂SeO₃; I, 0.14 mg as Ca(IO₃)₂; Co, 0.1 mg as CoCL₂.

⁴The diets of Exp. 2 are the same as in Exp. 1 with additional 3.5kg/T chromic oxide as an inert marker.

⁵Others contains antibiotics, enzymes, mycotoxin removal agent, sweetening agents, zeolite (carrier).

⁶Based on nutrient composition of feed ingredients according to NRC (2012).

⁷The mean of the 4 wk digestibility of DE in Exp. 2.
