Key Findings

01Indigenous sheep breeds (Bonga and Horro) possess distinct morphological characteristics and reproductive performance metrics.
02Sheep serve multiple purposes for smallholders, with income generation being a primary driver.
03Key constraints to sheep production include disease, feed shortage, and predators, varying slightly by region.
04Specific body measurements differed between breeds and sexes, indicating unique genetic profiles.

Application

Design takeaway

Designers of agricultural interventions should prioritize breed-specific characterization and integrate farmer-centric goals and constraints into their strategies.

How to apply

Before designing any livestock improvement program, conduct thorough on-farm characterization of the target breeds and consult with local stakeholders to understand their needs and challenges.

Project actions

01When researching a product or system, consider the inherent characteristics of the materials or subjects involved.
02Ensure your design addresses the practical challenges faced by the end-users.

Method & Evidence

AimTo characterize indigenous Bonga and Horro sheep breeds within smallholder farming systems to inform the design of community-based breeding strategies.

MethodMixed-methods research combining quantitative body measurements and qualitative survey data.

ProcedureResearchers conducted surveys using structured questionnaires, focus group discussions, and field observations. They collected quantitative data through body measurements (weight, length, girth, height, tail circumference and length) and qualitative data on production systems, flock sizes, reasons for keeping sheep, breeding performance (age at first lambing, lambing intervals), and production constraints.

Sample762 Bonga sheep and 816 Horro sheep.

ContextSmallholder sheep farming systems in Ethiopia.

Variables

IV["Breed (Bonga, Horro)","Sex (Female, Male)","Dentition (related to age)"]

DV["Body weight","Linear body measurements (length, girth, height, tail circumference, tail length)","Age at first lambing","Lambing interval","Flock size","Perceived production constraints"]

CV["Geographic location (districts)","Smallholder production system context"]

Strengths & Limitations

Strengths

+Comprehensive data collection methods (quantitative and qualitative).
+Inclusion of a substantial sample size for body measurements.
+Focus on practical, on-farm characterization relevant to smallholder systems.

Limitations

The study's findings are specific to the sampled regions and breeds. Generalizing these results to other areas or breeds requires further investigation. The study did not explore genetic diversity within breeds.

Reliability & validity

Reliability is likely high for quantitative measurements due to standardized procedures. Validity is strong for characterizing the breeds within their specific context, but external validity (generalizability) might be limited. Qualitative data validity relies on triangulation of methods (questionnaires, FGDs, observations).

Think critically

How might the 'multi-purpose roles' of sheep influence the prioritization of traits in a breeding program, and what ethical considerations arise when selecting for specific traits over others?

Design Principles

"Design solutions for agricultural systems should be informed by the specific biological and socio-economic context of the target populations and species."

This research highlights how the unique attributes of specific breeds, like the Bonga and Horro sheep, directly inform the design of breeding strategies. By recognizing these distinct traits, designers and agricultural experts can create more targeted and successful interventions that align with existing smallholder practices and address specific production challenges.

What This Means for Your Design

Different types of sheep have different body shapes and how well they have babies. Knowing these differences helps create better plans for farmers to breed sheep that are best for their specific needs and problems.

How to use in your project

1.Use this research to justify the need for understanding existing variations within a design problem space, especially when dealing with biological or naturally occurring systems.
