Abstract

Traditional livestock feed preparation relied on low-quality crop residues, leading to reduced production and increasing demand for non-conventional animal food. The utilization of cereal crop residues (CCRs) is limited because they contain a large proportion of lignocellulosic compounds and little nitrogen. This study focus on the future importance of agricultural byproducts as feeds for livestock, particularly fibrous byproducts that were blended with sugar cane industry filter cakes for ruminants, i.e. the predominant form of nitrogen avails in the filter cake that is the crude protein. The analysis on characterization of raw materials (filter cake, Teff straw, barley straw and corn cob) and prepared feedstock was 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), Flame atomic absorption spectroscopy, 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 %. Proximate compositions and the elemental profile of prepared feedstock were found as (in %) DM (87.3±0.85), ODM (87.75±0.6), MC (12.7±0.85), CP (11.18±1.02), Crude fat (11.67±0.7), CF (33.94±1.1), AC (12.24±0.6), Carbohydrates (52.19 %) and energy value (358.59 kcal. /100g). Also it contains 12.18-12.30% of mineral matters. Then overcoming to the production of feedstock by supplementing this high fiber, forage, crop residue (teff and barley straw and corn cob) with macro and micro constituent of sugar industry, filter cake is one of major contribution to the development of feed industry in this country, Ethiopia and have well shown opportunity to and decrease the waste of such industries..
