[Activity of lipoprotein lipase in different adipose deposits and its relation to adipocyte size in the cow during fattening or early lactation].
Twelve dry and eight lactating cows were slaughtered and the whole body was chemically analysed. Adipose tissue lipid and adipose cell size varied greatly with body condition and also with anatomical site (perirenal, omental, intermuscular, rump subcutaneous, leg subcutaneous). Lipoprotein lipase activity per adipose cell was very low in lactating cows, but very high in dry cows during fattening. Activity tended to be higher in omental adipose tissue and lower in subcutaneous adipose tissue. Total adipose lipoprotein lipase activity per cow was positively related with energy balance and negatively related with plasma non-esterified fatty acids. There was no correlation with body fatness or adipose cellularity.
