Factors Influencing the Lipogenic Rate in Swine Adipose Tissue

Abstract

Measurements of the lipogenic rate in adipose tissue samples obtained sequentially by biopsy from the same pig may be useful for many nutritional experiments. The average lipogenic rate over a short period (several days to 2 weeks) appears to be relatively stable if the pigs weigh about 20 kg initially and if approximately 10 animals are allotted to each experimental group. The lipogenic rate is readily influenced by the feeding regimen (amount and timing). It is easily lowered by less than ad libitum dietary intakes and is influenced especially by the intake pattern for several days preceding the rate determination. In two different experiments, the lipogenic rate obtained at either 20 or 50 kg body weight was not effective as a predictor of backfat thickness or loineye area measured 13 or 6 weeks later, respectively.
