Abstract
The potential searching on sources of livestock feed material is the major constrain in the sustainability of livestock sector for the future. The utilization of cereal crop residues (CCRs) is limited because they contain a large proportion of lignocellulosic compounds and little nitrogen. The filter cake is a poorly studied potential as forage for ruminants. In addition, they show higher fiber content. The analysis on characterization of filter cake, Teff straw, barley straw and corn cob were carried out through proximate analysis such as moisture content (MC), dry mater (DM), organic dry matter (ODM), ash content (AC), crude protein (CP), crude fiber (CF), Elemental analyzer, UV-Visible spectroscopy and Fourier transform infrared spectroscopy were used for analyzing the elemental profiles and functional feed constitutions. The proximate analysis of raw material feed stocks (in %) contains in the range of DM (96. 54 ± 0.7-89.5±0.5), ODM (98.33±0.3-79.4±0.4), MC (3.45±0.7-10.5±0.5), CP (2.32±0.58-12.92±0.36), CF (15.5±0.50-85±0.5), AC (1.69±0.03-20.6±0), FT (1.44±0.1-10.5±0.82), Carbohydrates (45.27- 90.42), energy value (327.26- 386.56 kcal.) and Sucrose of (3.85±0.83). And its elemental compositions can be addressed by their mineral matter contain up 1.69±0.03-20.6±0 %.The moisture content and dry matter contents may vary depends on factors such as cultivator of crops and cane, location, climate, dry length, soil pest diseases, cultivation practices, the harvesting practice and the processing of cans and crops. Large quantities of fibrous crop residues are already used as animal feed in many areas across these countries. There are too many areas in developing countries where ruminant livestock starves due to lack of feed. So this study shows that the direction of searching and compensating the availability of such important croup residues and the sugar industry by product (filter cake) as the raw sources of livestock feeds.
