Effects of rapeseed oil duodenal infusion on adipose tissue lipolytic activities of dairy cows during early lactation.

was higher (P < 0.1) from S than from P adipose tissue, without changes in the FFA/glycerol ratio. The basal FFA/glycerol ratio tended to be higher in group 0 in both tissues (table I). However, the activity of perirenal 3-glycerol-P dehydrogenase, an enzyme involved in (re)esterification of FFA, was the same in both groups. Basal glycerol release, and the FFA/glycerol ratio, tended to be respectively lower and higher in S than in P. These results probably reflect partial hydrolysis of triglycerides and a higher turnover rate of FFA.
