|Chemical composition (% of dry matter, DM) and fatty acid content (in % of total fatty acid methyl esters, FAME) of pasture hay, fresh pasture grazed and alfalfa pellets fed to Churra Tensina ewes during the peripartum period1|
|pasture hay||fresh pasture grazed||alfalfa pellets2|
|Dry matter M (DM, % of fresh matter)||87.5||18.9||93.3|
|Crude protein, CP||12.0||20.1||15.7|
|Neutral detergent fibre, NDF||50.4||42.3||35.5|
|Acid detergent fibre, ADF||26.8||21.6||23.8|
|C18:1 trans-11 (VA)||0.11||0.20||0.02|
|C18:2 cis-9 cis-12||7.53||8.51||18.65|
1SFAs (saturated fatty acids) were calculated as the sum of C12:0 + C14:0 + C16:0 + C17:0 + C18:0 + C20:0; MCFAs (medium-chain fatty acids) were calculated as the sum of C12:0 + C14:0; LCFAs (long-chain fatty acids) were calculated as the sum of C16:0 + C18:0 + C20:0; UFAs (unsaturated fatty acids) were calculated as the sum of (MUFA + PUFA); MUFAs (monounsaturated fatty acids) were calculated as the sum of (C16:1 + C17:1 + C18:1n-9 + C18:11n-7 + C20:1); PUFAs (polyunsaturated fatty acids) were calculated as the sum of (C18:2 t-t + C18:2c-c + C18:3n-6 + C18:3n-3 + CLA + C20:2 + C20:3 + C20:4 + C20:5 + C22:5 + C22:6).
2Supplement during 11 days in the pre-partum grazing ewes, when snow limited pasture availability.
