Investigation of the Usability as raw metarials an Fish Feed and Cultivation Ability of Niger (Guizotia abyssinica Cass.) Seed in Our Country

Niger (Guizotia abyssinica Cass.) oil seed has been cultivated since about 5000 years. It is heavily cultivated in South Ethiopia, India, Sudan, Uganda, Zaire, Tanzania, Malawi, Zimbabwe and West Indies, Nepal and Bangladesh. Recently, It’s cultivate is have been began in America . It is used in soaps, paints, lubricants, lighting fuels, fertilizers and cosmetics in very small quantities. The niger oil meal is the main protein supplement for livestock in Ethiopia. It is used especially in sheep and goat rations for growth, in cattle rations for milk. Niger meal contains approximately protein (34%) ,cellulose (20%) and ash (10%). In terms of chemical composition, niger meal, similar to sunflower meals,. The percentage of cellulose in niger dehulled meal decreases by 2%, the fat and protein ratios increase. Niger seed is a very rich seed with linoleic acid content and essential amino acids. In recent years, studies have been carried out on digestibility and replacing fish meal of niger meal in tilapia feeds. It has the potential to be cheaper oil source and raw feed material for suitable countries for cultivate. It was carried out in our review introduction of the plant, the comparison of the nutritional values of niger meal with some other fish feed raw metarial, and also a preliminary study for niger culture in our countr
