Anexperiment wasconducted toseetheeffectofhigherlevelsof rapeseedcake(15,20 and25%) inpoultrydiet onthe
performance of laying hen (Tetra SL). All the diets were isocaloric (within the range of 319 to 321 kcal 100 g:'),
isoproteinacious (17.19 to 17.31%) and the fibrecontents were within the recommended range (2.98 to 3.52%). The
experiment wasof28 daysduration. Eggsizewasmaximumforthe20%repeseedcakegroup (62.25g)followed bythe
25% group (61.24 g) and minimum for 15%rapeseed cake group (58.26 g). Egg size of standard group was 58.99 g.
The egg laying percentage was 60% for standard group and 59.33% for 25% rapeseed group. No difference in birds
live weight was observed due to feed variationthroughout theexperimental period.No mortality was recorded. Orga-
noleptic evaluation by trainedjudges revealed no difference in overall acceptability of eggs by all the groups.
