The study was conducted in Guagusa Shikudad district of the Amhara National Regional State (ANRS) with the objectives of husbandry practice characterization and evaluation of urea molasses treated highland bamboo (Yushania alpina) leaves in lactating dairy cows nutrition and evaluating the effect of bamboo leaf feeding on milk yield & milk composition of crossbred cows. A house hold survey was used to collect data on characterization of husbandry practice, feed resources and feeding system, bamboo leaf feeding value and its effect in dairy production. A total of 190 dairy producer households were interviewed individually with semi structured questionnaire. On-farm feeding trial was conducted using twelve lactating cows with initial body weight (328.08kg+0.98), initial milk yield (3.14L+0.78) per day of uniform parity (2) and stage of lactation (early) using a Randomized Complete Block Design with three dietary treatments and four replications. Survey data were collected, organized and entered in to SPSS 23 software and analyzed while the feed trial experiments and lab results were analyzed by using SAS software 9.4. The household survey revealed the presence of rural small-holder and peri- urban, dairy production systems. The major livestock feed resources are natural pasture, crop residues and local industrial by-products and bamboo leaf though deliberate feeding system of bamboo leaf was not practiced. Feed shortage is one of the major constraints of milk production in the area especially in the dry season. The on-farm feeding trial result showed a significant difference (P<0.05) between urea molasses treated bamboo leaf feeding (T2) and others (T3 untreated highland bamboo leaf feed and T1 control) in terms of increased milk yield. Therefore, further works are needed in areas of bamboo leaf treatment and feeding for viable milk yield.
