Inefficient management and use of water is unanimously the most single constraint of agricultural production of Ethiopia.
This study was conducted to assess the effect of livestock feed sourcing and feeding strategies on livestock water productivity (LWP) in mixed crop–livestock production systems of the Blue Nile Basin in Ethiopian Highlands. Three districts representing diverse agricultural farming systems were considered. Each district further stratified to different farming systems. Multi-stage stratified random sampling technique was employed to select farm households. Household survey, group discussions and plant biomass sampling were done to generate data on beneficial outputs, water depleted and feed sourcing and feeding strategies. LWP was estimated as a ratio of livestock’s beneficial outputs and services to depleted water.
The results indicated that the major feed sources were mainly from crop residues (58.5 to 78.2%), natural pasture (10.9 to 33.4%) and aftermath grazing (9.9 to 24.3%) in study farming systems.
