Abstract:
This study aimed to classify smallholder dairy production systems (DPSs) in southern highlands
of Ethiopia by analyzing land allocation for various crops and characterizing their integration
with livestock/dairy. After the classification, the study primarily characterized DPSs based on
feed types and feed resources, feeding methods, breed types and breeding methods, milk yield
and income variation. Additionally, as an objective it evaluated milk and butter handling,
production, and consumption, assessed supply chains and physicochemical quality, and
examined the livelihood status of smallholder dairy producers across the different DPSs in the
Southern Highlands of Ethiopia. Interviews with 360 smallholder farmers from the former
SNNP and Sidama regions provided firsthand data, supplemented by secondary sources. The
classification of these farmers, using K-means clustering, categorized them into four DPSs: 31%
were classified as Diversified Crop-Based (DCB), 28% as Enset-Based (EB), 24% as Cereal-
Based (CB), and 17% as Cash Crop-Based (CCB), where coffee, khat, vegetables, fruits, and
sugarcane are predominant. Based on this classification, sampling for the analysis of the
physicochemical properties of milk and butter focused on two contrasting systems, CCB and
EB, which varied in the types of feed used. Sixty milk samples were collected from each system,
with 20 samples from each actor (producer, retailer, and consumer). For butter, 12 samples
were collected from each system, with 6 samples from each actor (producer and retailer). The
CCB system, which dedicated 56% of farmland to cash crops, reported the highest income and
intensive dairy practices compared to the other DPSs. Ownership of improved dairy cattle
breeds, use of agro-industrial byproducts as feed, and practicing stall feeding were among the
better practices observed in this DPS, indicating a move towards intensification of dairy
production. In contrast, the EB system's 33% enset allocation provided significant feed residues
for local cattle and had more local breed ownership. The CB system allocated 47% of land to
cereals, making cereal residues the primary type of residue used as dairy feed. Cultivating
grasses like Pennisetum pedicellatum and Phalaris arundinacea was also highly valued in this
system. The DCB system, with its diverse crops, provided varied residues for dairy feed. These
findings revealed unique characteristics across dairy systems, indicating a positive correlation
xvi
between crop commercialization and dairy intensification. Over two-thirds of respondents in
the CCB system used modern milk handling devices, compared to just 21% in the EB system.
Cleaning practices varied, with Eucalyptus globulus used in CB, DCB, and EB systems, while
enset plant residues were specific to CCB. Producing 1 kilogram of butter required more milk
from crossbred cows (18 liters) than from local breeds (13 liters). Significant variation (P<0.05)
in butter production was observed between the CB and EB systems, requiring 15 and 13 liters,
respectively, for local cows. The CB system required the least milk from crossbred cows (15
liters) for 1 kg of butter. Milk production was highest in the CCB system and lowest in the DCB
system, while whole milk consumption remained consistent across all DPSs; however, butter
production was highest in DCB and lowest in CCB. Raw milk quality declined along the supply
chain, With fat content dropping from 5.3% at producers to 4.3% at a retailers, and TS from
13.2% to 11.8%, likely due to adulteration. Similarly, butter quality deteriorated, with fat
content decreasing from 85% at producers to 80% at retailers, and moisture increasing from
15% to 20%. The EB system exhibited higher fat and total solids (TS) levels in raw milk
compared to the CCB system, likely due to better grazing conditions and feed diversity. Overall,
the EB system demonstrated superior quality in both raw milk and butter compared to the CCB
system. Social, physical, and financial assets varied significantly across DPSs, with the CCB
exhibiting the highest levels. CCB had better physical capital due to improved cattle housing
and higher financial capital from increased dairy income and savings, while DCB and EB had
more natural capital from abundant grazing land. Positive correlations were found between
social, financial, and physical capitals. The livelihood capital radar diagram revealed that dairy
farming had the greatest impact in the CCB system and the least in the EB system. The CCB
dairy production system shows strong potential for intensification and comparatively better in
their livelihood, with higher adoption of improved dairy production and milk and butter
handling technologies. In contrast, the EB system relies on extensive practices, while the CB
and DCB systems fall in between. Targeted interventions are needed to enhance productivity
and technology adoption across all systems. For CCB, effors should enhance feed efficency and
handling practices, while for EB , the focuse should be adopting technology, improving milk
handling and supporting traditional dairy farming in all systems
