The study area, encompassing the districts of Alefa, North Achefer, Takusa and Quara, is home to an estimated 814,021 people and roughly 130,472 registered smallholder farm households. Spanning altitudes from 500 to 2,300 meters above sea level, the landscape supports a diversified crop-livestock mixed-farming system in which cereals, pulses, oilseeds, vegetables, fruits, tubers, spices, livestock and their products are all potential components of household food supply. Between April 2022 and January 2023, researchers administered structured questionnaires capturing the full range of plant-sourced and animal-sourced commodities produced by each household, grouping outputs into 12 food groups following guidelines from the Food and Agriculture Organization and the FANTA framework for dietary assessment.

The headline figure from the analysis is that the average smallholder household in northwest Ethiopia produces 43.53 quintals of crops per year, of which cereals account for 25.47 quintals, or 58.51 percent of total production. Maize dominates, with an average of 12.77 quintals per household annually, followed by millet at 4.61 quintals, sorghum at 3.96 quintals and teff, the culturally central Ethiopian grain, at 2.33 quintals. Pulses and nuts contribute an average of 5.74 quintals, led by soybeans and grass peas, both of which show clear agro-ecological sensitivity: soybeans are concentrated below 1,000 meters in altitude while grass peas dominate the mid-altitude band between 1,500 and 2,300 meters. Oilseeds, including sesame, niger seed, sunflower, linseed and rapeseed, average 2.33 quintals per household, with sesame standing out as the principal cash crop in this category.

Micronutrient-rich foods tell a more sobering story. Average annual production of vegetables is 5.22 quintals per household, while fruits lag dramatically at just 0.62 quintals, despite the region’s diverse agroecology being well suited to crops such as avocado, mango, banana, papaya and watermelon. Ethiopian cabbage, intercropped with maize, is among the most common vegetables, and crops such as okra appear only in specific low-altitude pockets of Quara and Alefa. Only 49 percent of households cultivate any tuber or root crop at all, and a mere 23.22 percent grow spices, averaging 0.77 quintals annually. The authors note that households have substantially less experience producing fruits and vegetables and do not regard these crops as being as significant as cereals, a perception with direct consequences for dietary quality given the role these food groups play in supplying vitamins and minerals.

To identify the drivers behind these patterns, the researchers deployed multiple linear regression models, testing demographic, socioeconomic and institutional predictors while screening for multicollinearity using variance inflation factors and checking robustness with quantile, robust and MM regression. The results reveal a consistent and striking pattern: access to irrigation is among the most powerful levers available. Households using small-scale irrigation produced 21.77 quintals more crops than non-users, largely because irrigation enables more than one production season in a system otherwise hostage to rainfall. Irrigation user households also produced 3.25 quintals more fruit per year than non-users, making water access a decisive factor in diversifying production toward nutrient-dense food groups such as fruits and vegetables. Yet only 13.60 percent of surveyed households actually use irrigation, representing an enormous unrealized potential.

Draft and transport animals emerge as equally consequential. Each additional ox increases a household’s total crop production by 6.02 quintals, and each additional donkey adds 6.06 quintals, reflecting the central role these animals play as traction power and as transport for inputs and harvested yields. Male-headed households produce 10.53 quintals more total crops than female-headed households, a gap partly attributed to cultural norms that direct female farmers toward backyard cultivation rather than field-scale cereal production. Contacts with agricultural extension workers also translate directly into output, with each additional contact during a production season associated with 1.63 quintals of additional crops. Distance to market operates in the opposite direction: every additional kilometer separating a household from the nearest market center is associated with 0.7 quintals less crop production.

The analysis also uncovers a subtle and counterintuitive finding about education. Each additional year of schooling by the household head reduces cereal production by 0.37 quintals, suggesting that more educated decision-makers diversify into a wider range of crops rather than concentrating on staples. Consistent with this interpretation, an additional year of schooling increases pulse and root crop production by 0.24 quintals. Household labor structure matters too, with each additional family member aged 15 to 64 adding 1.4 quintals of cereals, while households that factor crop management difficulties into their planting decisions produce 2.7 quintals less than those that do not, indicating a precautionary effect that constrains output.

On the livestock side, the picture changes considerably. Ninety-eight percent of households own at least one type of animal, with average holdings of 6.00 tropical livestock units, equivalent to roughly 1,500 kilograms of live weight. Animal-sourced food production averages 248.61 eggs, 117.46 liters of milk and milk products, 132.63 kilograms of meat including chicken, 2.96 kilograms of fish and 8.59 kilograms of honey per household per year. The regression results show that education of the household head and total crop output significantly boost egg production, with each additional year of schooling adding 10.84 eggs annually and each quintal of crops adding 1.78 eggs, likely because cereals serve as feed for poultry. Livestock ownership itself is the dominant predictor of meat availability, with each additional tropical livestock unit associated with 11.28 kilograms more meat produced or purchased, while each additional unit raises milk production by 15.05 liters. Contacts with extension workers add 7.21 liters of milk per contact, underscoring the value of advisory services in dairy management.

Intriguingly, several determinants of livestock production run counter to those for crops. Whereas market distance suppresses crop output, livestock holdings actually increase by 0.17 tropical livestock units for every kilometer a household sits from a market center, and cooperative members hold 1.07 more units than non-members. Arable land adds 1.18 units per hectare, while aging household heads hold fewer animals, with each year of age associated with a decline of 0.092 units. School-age children between five and fourteen play a pivotal role in the free-grazing system, with each additional child in that age band associated with 0.77 more livestock units, a reminder that child labor remains structurally embedded in traditional herding economies.

The authors conclude that promoting cost-effective small-scale irrigation through water-harvesting technologies, improving agricultural management practices, and adding value to livestock production by introducing nutrient-dense animal feeds could substantially raise both the quantity and diversity of food available to smallholder households. They argue that agricultural extension services should be explicitly nutrition-sensitive, framing agriculture not merely as a matter of production volume but of the range of food groups reaching households. The study acknowledges limitations inherent in its cross-sectional design, which captures a single production season and cannot fully reflect long-term household experience, nor determine whether production levels meet the dietary needs of household members. Even so, the findings provide a detailed evidence base for policymakers seeking to transform traditional, rain-fed, and vulnerable smallholder agriculture into a springboard for nutrition-sensitive food systems capable of tackling the underlying causes of food insecurity and malnutrition in Ethiopia and comparable settings across sub-Saharan Africa.

The study, led by Rogers Kigoonya of the Namayingo District Local Government together with colleagues at Makerere University, was conducted between July and October 2024. Namayingo is an unusual place for cattle research. The district, which covers 532.9 square kilometers of Lake Victoria territory near the Kenyan border, historically depended on fishing. As fish stocks dwindled, communities transitioned into subsistence farming that integrates small-scale cattle and crop production. Today, of the 11,384 cattle-keeping households in the district, more than half own only one or two animals, and 98.6 percent of the district herd consists of indigenous breeds. Despite the economic importance of these animals, scientific data on their reproductive performance in the district had been almost entirely absent.

To fill this gap, the team used a multi-stage sampling design targeting smallholder farmers in the sub-counties of Buyinja, Buhemba, Banda, and Mutumba. Data came from three sources: physical examination of the cattle, direct observation of farm management practices, and a pre-tested structured questionnaire administered to 90 farmers. Pregnancy status was determined through a combination of farmers’ reports of non-return to heat, visual observation, and rectal palpation performed by a veterinarian using a standardized protocol. Body condition scores were recorded on a five-point scale, and calving intervals were calculated from the two most recent consecutive calvings to minimize recall bias. Farmers with more than six cattle were excluded, keeping the study firmly focused on the smallest production units.

The headline numbers reveal a system operating below its potential. The average calving interval was 13.8 months, exceeding the 12-to-13-month benchmark recommended for achieving one calf per cow per year, the standard reproduction index for profitable cattle keeping. Services per conception averaged 1.48, meaning cows typically required roughly one and a half matings or inseminations before conceiving. Repeat breeding, defined as failure to conceive after three or more services, affected only 2.1 percent of cows, a remarkably low figure that the researchers attribute to the resilience of indigenous breeds. Dystocia, or difficult calving requiring assistance, told a far grimmer story: at 15.2 percent, it was roughly three times the internationally reported rate of less than 5 percent and well above figures documented elsewhere in East Africa.

The dystocia finding is particularly consequential for calf and cow survival. The researchers suggest the high prevalence may stem from the composition of the study herd, since 40.2 percent of cows were primiparous, meaning they were calving for the first time with pelvic structures that are not yet fully developed. In addition, the dominance of indigenous cattle raises the likelihood of mismatches between sire and dam sizes, both through artificial insemination with inappropriate semen and through uncontrolled natural mating with bulls of unknown conformation. Difficult calvings delay the return of ovarian activity, lengthen the time to the next conception, and can permanently damage fertility, making this single statistic a plausible driver of the extended calving intervals observed across the district.

When the team ran multivariable binary logistic regression on pregnancy status, three factors emerged as decisive. Body condition score, a direct proxy for nutritional status, was highly significant, echoing decades of evidence that thin cows suffer from anestrus, delayed conception, and reduced fertility. Housing mattered as well: cows kept in shelters had more than four times the odds of being pregnant compared with cows without any housing (odds ratio 4.24, 95 percent confidence interval 1.34 to 13.45). Shelter reduces environmental stress and protects animals from injuries that compromise fertility. Management system also exerted a strong effect, with tethered cattle showing drastically reduced odds of pregnancy compared with zero-grazed animals, an odds ratio of just 0.033. Alarmingly, 83.3 percent of farmers in the study provided no cattle housing at all, and 76.7 percent relied on communal grazing of natural pastures with no sown or conserved feed.

A generalized linear model applied to calving interval painted a complementary picture of which cows breed back fastest. Age was significant, with cows aged four to eight years showing shorter intervals than animals older than eight, consistent with the declining fertility of aged cows and the delayed ovarian recovery of young ones. Parity also mattered: multiparous cows had shorter calving intervals than biparous cows, likely reflecting physiological adaptations from previous calvings that allow a faster return to estrus, whereas second-calf cows often need longer postpartum recovery. Most strikingly, breeding method proved influential. Cows bred by artificial insemination had significantly shorter calving intervals than those mated naturally, a difference the authors link to planned mating and timely insemination rather than to the biology of the semen itself. Yet in practice, natural mating dominated the district, and only a quarter of farmers kept any records, mostly health or visitor logs, leaving most producers blind to the reproductive trajectories of their own animals.

The findings carry clear implications for extension services and policy. Because housing, body condition, and management system all shaped pregnancy outcomes, interventions do not need to be high-tech to be transformative. Simple shelters, strategic supplementation to improve body condition before breeding, and a shift from tethering toward managed grazing or zero-grazing units could raise pregnancy rates substantially. Expanding access to artificial insemination, paired with sire selection that accounts for the size of indigenous dams, could simultaneously shorten calving intervals and reduce the dystocia rate that currently endangers both cows and calves. Basic record keeping, even a simple notebook of calving and mating dates, would allow farmers to identify non-productive animals and cull or treat them in time. The study’s authors recommend appropriate housing and breeding interventions as the priority actions for Namayingo and for comparable smallholder systems across the region.

Beyond the local context, the research contributes to a broader scientific conversation about why cattle fertility lags across African smallholder systems, where livestock underpin more than 70 percent of rural Ugandan livelihoods and cattle account for roughly 73 percent of the gross value of livestock output. Suboptimal reproduction ripples outward: fewer calves mean fewer replacement animals, less milk, less meat, lower household income, and diminished resilience against climate and market shocks. By identifying specific, modifiable risk factors in a non-traditional cattle-keeping district that transitioned from fishing to farming, the study demonstrates that reproductive decline in small herds is neither inevitable nor purely biological. It is, to a large degree, a management problem with management solutions, and the evidence from Namayingo suggests those solutions are well within reach of the farmers who need them most.
