Abstract
The use of imported rapeseed meal (RSM) from India and China as a source of protein substituted to soybean meal (SBM) was investigated in layer diets. The levels of RSM were 0-16% of the diet in Exp I and 0-12% in Exp II which were equal to the substitution level of SBM at 0-100% and 0-75%, respectively. The ME content of the diets in Exp I was allowed to decrease with the increased level of RSM while all diets in Exp II were adjusted to be isocaloric with rice bran oil. In each experiment of 252 days, 2 40 heads of Hubbard pullets were alloted to 4 treatments each with 5 replicates. They were individually kept in a battery cage with ad libitum feeding under 17 hours light daily. Without ME adjustment (Exp I) feed intake and egg production decreased with the increased level of RSM. On the other hand, when ME of the diets was adjusted to be isocaloric to the control (Exp II), there were no significant differences on egg production and feed intake. Egg size in both experiments was inferior with the increased RSM level.
