It is cultivated in West area extending from some parts of the Mediterranean region to India and the area of afyon nurder and Isparta of Turkey (Taha, 1997). The seeds of Nigella Sativa have long been used by Armenians and Syrian as flavoring agents in cheese and bakery products (AbolJDonia and Abdel-Kader, 1979), Some Egyptians also uses the seeds as diuretic carminative and flavoring agent (Sabreen, 1996), During the last five decades Nigella Sativa L seeds have been subjected to extensive investigation included its chemical composition (Gad et a/., 1963). its pharmaceutical and therapeutic effects (Mandour et a/,. 1998), its bacterial and fungal actuaries (Islam et a/., 1989; Hanafy and Hatem, 1991; Mahmoud at al. 1992; and Mahmoud, 1993). Furthermore, there are a high need for increasing the economical efficiency of animal production. Feeding cost in animal production represented the largest part of total cost. being 60-70% So that other unconventional materials must be used in animals diets partially or completely. Protein supplements constitute the highest valuable costs ingredients in the animal diets, Niglella Sativa meal (NSM) is one of the untraditional feeds of high protein content of about 30% (Khalifah, 1995 and Zewei!, 1996), and most of the essential amino acids as well as theremaining oil after extracting of about 15% (Abdel-AII and Attia, 1993) The NSM could be used as a flexible diet because of its relatively high CP and energy contents. Moreover, NSM can be used to replace a part of the concentrate feed mixture protein (CFM-protein) economically in diet of poultry, (Khallfah, 1995 and EI- Ghamry et ai” 1997), fish (Mohamed, 1997) and sheep (Awadalla, 1997; Gabr, 1998; Gabr et ai, 1998 EI-Ayek et a/., 1998 EI-Ayek et a/., 1999) In rabbits Niglella Sativa was utilized in form of seeds (Nasr et a/. 1996), crashed seeds (Daghash et ai, 1999 and Abd EI-Hakim et a/. 2002) and NS-meal( Saad 2001)
