Forage preservation (grazing vs. hay) fed to ewes affects the fatty acid profile of milk and CPT1B gene expression in the sheep mammary gland

Table 3 Main FA categories content (%) in milk of Churra Tensina ewes at the fifth week of lactation, according to forage type ^1–3

¹Within a row, means without a common superscript differ (P < 0.05). SE is the standard error.
²HAY group: ewes received hay from mountain pastures; GRE group: ewes grazed low mountain pastures.
³SFAs (saturated fatty acids) were calculated as the sum of C4:0 + C6:0 + C8:0 + C10:0 + C12:0 + C14:0 + C16:0 + C17:0 + C18:0 + C20:0 + C22:0 + C24:0; SCFAs (short-chain fatty acids) were calculated as the sum of C4:0 + C6:0 + C8:0 + C10:0; MCFAs (medium-chain fatty acids) were calculates 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 + C22:0 + C24:0; 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.
