  This study was conducted to determine the effect of replacing different levels of rapeseed meal with soybean meal on the performance of commercial laying hens. Four levels of rapeseed meal; 0, 5, 10 and 15% were used in diets of 144 Hi-Line (W-36, Strain) laying hens from the age of 44 to 56 weeks. Hens were distributed in a randomized complete block design with 4 treatment, 3 replicates and 12 hens in each replicate. The parameters measured were the feed intake, hen-day egg production, egg mass, feed conversion ratio and egg weight. With increasing of rapeseed meal level in diets, feed intake was showed elevation (p<0.05). Egg weight was significantly higher when birds fed 10% rapeseed meal (p<0.05). No specific trend was observed on the effect of rapeseed meal on egg mass and feed conversion ratio, however these parameters were higher in groups that fed 10% rapeseed meal. With increasing rapeseed meal in diets, production ratio was decreased. It was concluded that; the replacement of 10% rapeseed meal with soybean meal in the layer diets might be useful and had economical benefits for producers.

  One hundred and forty four of Hy-line (W-36) laying hens from the age of 44 to 56 weeks were used to evaluate the effects of replacing different levels of rapeseed meal with soybean meal on egg quality characteristics of commercial laying hens. The rapeseed meal was replaced with soybean meal at the levels of 0 (control), 5, 10 and 15% for 12 weeks. Hens were distributed in multi-observational completely randomized block design with 4 treatments, three replicates and 12 hens in each replicate. The parameters used to assess were haugh unit, shell thickness, shell weight, shell strength and yolk index. Results showed that addition of 10% rapeseed meal in diets increased (p<0.05) eggshell weight. With increasing of rapeseed meal level in diets, yolk index had showed decline (p<0.05). No specific trend was observed on the effect of rapeseed meal on haugh unit, shell thickness and shell strength, however these parameters were higher in groups that fed 10% rapeseed meal. We did not observe any health problems of the hens during the experiment.
