| Abstract |
The experimental work of the present study was carried out at the Poultry Research Station, Seds, Beni Swiff, Animal Production Research Institute, Agriculture Research Center, Ministry of Agriculture, Dokki, Egypt, during the period from January to May, 2001 to study the effect of partially and completely replacing of soybean meal (SBM) protein with Nigella Sativa meal (NSM) protein on laying performance, some carcass parameters, economical efficiency as well as nutrient digestibilities of the experimental diets. Birds of 4 local strains of 28 week of old fed on layer com- soya diets in which SBM was replaced by NSM protein at levels of 0, 25, 50, 75 and 100%.
A total number of 360 hens and 40 cocks from Bandarah (BA), Gimmizah (GM), Dandarawi (DA) and Dokki-4 (DK-4) (90 hens plus 10 cocks each) strains of 28 week of old were used in this experiment.
The experimental birds were divided into 5 equal groups (18 hens + 2 cocks each). Five experimental com-soybean meal layer diets were formulated from a layer basal diet by partially and completely replacing SBM protein with NSM protein at replacement ratios of 0 (control), 25,50, 75 and 100 %.
From the economical point of view, under the present experimental conditions, it is advisable to use NSM protein at levels of 25, 50, 75 and 100 % to replace of SBM protein in GM, BA, DK-4 and DA hen diets.
