Abstract: ]-glucose infusion, but protein expression of SREBP (68 kD) was reduced. Results indicated a coordinated inhibition of parameters related to milk fat synthesis in the mammary gland in CLA and EFA+CLA cows. The inhibitory effect on milk fat synthesis was associated with an elevated carbon flux of glucose in glycerol of the triglycerides in milk fat. Reduction of glucose flux in casein by CLA treatment and less milk urea pointed at less nonessential AA synthesized from glucose, but regulation of milk protein synthesis was barely affected by CLA and EFA+CLA. The EFA treatment had no influence on glucose flux into milk ingredients and seems to barely affect milk fat and protein synthesis in the present study.
