| Abstract: | 1. Brown egg layers were fed diets differing in oil content, oil source and linoleic acid concentration and the effect on performance from 22 to 69 weeks of age was studied. 2. The birds responded with an increasing mean egg weight up to a linoleic acid intake of 2.75 g/bird d. 3. Increasing the intake of readily absorbable oil without increasing linoleic acid concentration did not increase mean egg weight. |
