The study was conducted in Fogera Woreda, South Gondar Zone of the Amhara National Regional State with the objectives of on-farm evaluation of urea treated straw and rice bran supplementation on milk yield and composition of Fogera cows. The area has high potential for rice production and is native origin of Fogera cattle breed. Despite the high production potentials, improvements in utilization system for feeding rice straw to livestock are not properly addressed. As a result, assessment of the potentials, opportunities and effects of urea treated rice straw and rice bran on milk yield and composition was required to serve as a basis for the better development of these feeds as potential feed resources for milk production. To address these issues, a single-visit-multiple-subject survey was carried out and 120 rural households who were individually interviewed with structured and semi structured questionnaires. Twenty Fogera cows used for the feeding trial were blocked on weight and milk yield bases having an initial mean body weight of 259.75±33.8 and milk yield of 1.23± 0.26. The treatments were grazing + untreated rice straw(T1), grazing +urea treated rice straw (T2), grazing +urea treated rice straw + rice bran (T3), and grazing +urea treated rice straw + formulated concentrate mix (T4). The survey result in the study area revealed that 44,223 tons of unhulled rice grain, 38,603 tons of rice straw dry matter, and 4,422 tons of rice bran, respectively were produced in 2008. And the on farm feed supplementation has resulted in a mean milk yield of 1.2 kg/cow/day in T1, and 2.36, 2.48, and 2.63 kg/cow/day in T2, T3, and T4, respectively. The partial budget analysis indicated a daily income of 4.20, 6.82, 6.50, and 6.59 ETB, where, T1 was lesser by a net profit of 2.62, 2.30, and 2.39 over T2, T3, and T4 respectively. This indicates that supplementary feeding of urea treated straw and rice bran had significant contribution to the development of dairy business in the study area.
