Means within a row with different superscripts significantly differ among feeding system during lactation (P < 0.05).
Indoor = ewes fed a total mixed ration; Alfalfa = grazing on alfalfa; Sainfoin = grazing on sainfoin.
Control = commercial concentrate; QUE = commercial concentrate with 5% quebracho.
RMSE = root mean square error.
FM = fresh matter.
