^a,b Means within a row with different superscripts differ (P < 0.05).

¹GEI = gross energy intake; E_feces = energy losses in faeces; E_urine = energy losses in urine; E_methane = energy losses in methane; MEI = metabolizable energy intake; HP = heat production; RE_total = total recovered energy; RE_milk = recovered energy in milk; RE_body = recovered energy in tissue (TEbody = MEI − HP − Emilk).

²BRL = barley; OP = orange pulp; SH = soybean hulls.

³1 = first period; 2 = second period.

⁴ SEM = standard error of the mean.
