1. Calorimetric studies were conducted with groups of five chickens to determine if availability of metabolisable energy (ME) changed with increasing concentrations of corn oil or tallow added to six diets. 2. There was no significant difference between the diets in the regression equations relating ME intake and energy retention. There was a slight increase in partial efficiency with increasing ME intake, from 82% at the mean daily intake of 1 874 kJkg W0.75 to 85% at the highest intake of 2 300 kJ/kg W0.75. 3. Energy retention was greatest at the highest concentration of tallow (140 g/kg) in the diet; there was an indication that availability of ME may be greater for tallow than for oil at a similar ME inclusion rate when compared at the mean daily intake of ME. Without any lipid in the diet, partial efficiency was 77% and energy retention was lower than on the diets with added oil or fat. |
