Abstract
ABSTRACT Cellularity of the abdominal fat pad and lipogenesis in the liver were studied in 9-week-old chickens after eight generations of selection for increased body weight gain (line W), increased food consumption (Line F), decreased food conversion ratio (line E), or at random (line C). The average volume of the adipose cells in the abdominal fat pad was greatest in the birds of line F and smallest in birds of line E. Differences in the number of adipose cells in this fat depot in birds from all the lines can be largely attributed to differences in growth rate. Lipogenesis, as measured by in vitro incorporation of 14C-ghicose into lipid and the activity of NADP-malate dehydrogenase, was highest in birds from line F and lowest in birds from line E. These differences in lipogenesis among groups could not be attributed to differences in food consumption or growth rate. The biochemical basis for differences in lipogenesis among lines is not clear at this stage. (Key words: adipose cells, malic enzyme, lipid synthesis, abdominal fat pad, chickens)
