Conjugated linoleic acid (t10, c12)-methylester (omega-6-fatty acid as t10,c12- octadecadienoic acid (conjugated linoleic acid)-methylester (CLA(t10,c12)-ME))

What it is. Additive consisting of an omega-6 fatty acid preparation in the form of a methyl ester of octadecadienoic acid (conjugated linoleic acid, t10,c12), produced by BASF SE. It is available in liquid or solid form, combined with sunflower oil fatty acids and, for the solid form, hydrogenated vegetable oils, colloidal silica and calcium sulphate as carriers.

What it is for. This is a zootechnical additive, functional group 4d (other zootechnical additives), used in fattening pigs and dairy cows. In fattening pigs it is incorporated into feed within the authorised content range; in dairy cows the daily ration intake of CLA(t10,c12)-ME is capped. It is generally used to modulate fatty acid metabolism and body composition parameters in these production contexts.

Points to watch. In fattening pigs, the additive content in feed must remain between 400 and 5 000 (units as per the annex) mg/kg; in dairy cows, daily intake must not exceed 10 g/head/day. Storage conditions and thermal processing stability must be specified in the instructions for use, and operators must put in place procedures to manage health risks for handlers.
