Abstract
Selection for abdominal fat pad size in mature hens has yielded 2 divergent strains of lean and obese chickens. The females in the obese line have a greater amount of total body lipid by 6 wk of age. Liver slices from 6- and 17-wk-old obese chickens incorporated significantly more 3H2O into extracted fractions of total lipid and saponified fatty acids. Palmitate esterification by abdominal fat pad slices from 12-wk-old pullets was the same for both strains when activity was expressed per unit weight of tissue. The two-fold difference in size between the lean and obese fat pads at this age indicates a significantly greater degree of total esterification in the obese birds. At 6-, 12- and 17-wk of age, the 2 lines exhibited similar concentrations of plasma glucose, total protein and triglycerides.
