Abstract

Rape seed of the variety "Express" was de-hulled before subjecting it to oil withdrawal by pressing or a combination of pressing and extraction. Nutrient concentrations and metabolizable energy content (AME(N)) of the accruing by-products, extraction meal and oil cake, were determined in broilers and laying hens. The same procedure was carried out with the by-products of non de-hulled (normal) seed of the same variety. The following improvementsof feeding value were obtained by de-hulling of rape seed:The concentrations of crude fiber and neutral detergent fiber (NDF) were decreased in extracted meal by 38 and 28%, respectively, and in cake by 40% each. A marked decrease was also observed for the lignin content. Crude protein and amino acid concentrations increased markedly. By-products from de-hulled rape seed had a distinctly higher energy concentration (kJ AME(N)/kg dry matter) as compared to by-products from normal seed (Rape seed meal: broilers, 6.17/6.94, normal, and 7.87/8.27, de-hulled, respectively; laying hens, 8.08, normal, and 9.91, de-hulled, respectively;rape cake: broilers, 8.9/11.42, normal, and 11.26/13.05, de-hulled, respectively).
