Milk yield and milk composition were measured on all ewes on day 1 and 7 of each grazing period. Milk samples were assayed for milk fat, protein, and lactose contents (Milkoscan FT+, Foss Electric, Hillerød, Denmark). Excluding the pre-experimental, adaptation period, 632 samples were gathered from March 20, 2013 to April 28, 2013 (E1), and 598 samples were gathered from 11 March 2014 to 22 April 2014 (E2), resulting in a total of 1,230 samples.
