Effect of SUBSTITUTION some untraditional sources of proteins FOR SOYBEAN MEAL IN DIETSof New Zealand White rabbits
Introduction Since the discovery of mad cow disease in the last decade, soybean meal have increased demands and accordingly raised its feeding cost. In Egypt, there is a continuous increase in the prices of traditional plant protein sources such as soybean meal, owing to its universal use. Therefore, search for cheaper alternative vegetable protein sources Is urgent. There are a large amount of crops, vegetables and fruit residues could be a new source of feedstuff with low price and high quality proteins which can be used to solve feed shortage and produce least cost diets for rabbits.
NIGELLA SEEDS Nigella seed (Nigella sativa) frequently referred to as black cumin, serves as an important medical crop in many countries and is primarily consumed as medical oil; second, Nigella seed meal (NSM) after oil removal can be used as a protein-rich meal.NSM contains most of the essential amino acids, with crude protein about 33% (EL-Nattat and ELKady,2007) .Nigella sativa control and buffer the condition of the stomach and intestine (Projapati et al., 2003). The black cumin seeds contain thymoquinine that has antibacterial, and immunopotentiating activities via increasing neuterophil of the body against infection (Kanter et al., 2005). Black cumin oil and its derivatives inhibit eicosanoid generation in leukocytes and membrane lipid peroxidation (El-Dakhakhny et al., 2002). Besides, the seeds contain eight essential amino acids that improve natural immune system activity (Omar et al., 1999).
ROCKET SEEDS Production of rocket in Egypt has been stead increased for the strong demand to volatile oils for pharmaceutical purpose. This plant was found to be incarnate the body condition to counteract the stress of illness (Eisenberg et al., 1993).The rocket seeds contain carotenoids, vitamin C,flavonoids such as appiin and luteolin and glucosinolatesthe precursors of isothiocyanates and sulfaraphene (Talalay and Fahey, 2001), volatileoilslike myristicin, apioleβ-phellandrene (Bradley, 1992; Leung and Foster, 1996). Glucosinolateswere found to have several biological activities including anticarcinogenic,antifungal, antibacterial plus theirantioxidant action(Kim et al., 2004). They also contain Zn, Cu, Fe, Mg, Mnand other elements (Abdo, 2003) After oil removal, rocket seed meal which increase immune response. (RSM)could be used asa protein-rich meal for feeding rabbits with crude protein about 32% (El-Nattat and El-Kady, 2007). This product is expected to increase in near future due to high demand of the extracted oil .

It can be concluded that rocket seed meal at 10.5% level of the diet in NZW rabbits had the best results without adverse effects on the growth performance, kidney or liver function, however further studies are needed in this aspect.

Table 4: Effect of different levels of NSM on serum blood constituents a, c Means in the same row bearing different letters, differ significantly (P≤0.05)
It could be recommended to use Nigella seed meal in NZW rabbit diets as a non-traditional source of plant protein up to 12% without harmful effects on the growth performance and blood constituents. Further studies needed from the practical point of view.
