Thesis Abstract

The rapid penetration of smartphones among smallholder farmers presents an opportunity to enhance livestock feeding efficiency through precision nutrition, yet adoption barriers, data reliability, and context-specific performance remain poorly understood in developing-country agroecologies. This study investigates the design, implementation, and impact of a smartphone-based precision livestock feeding (PLF) system tailored for smallholder pig and poultry operations in rural regions, examining how real-time feed adjustment, biometric monitoring, and decision-support analytics influence feed conversion ratios, growth performance, and cost efficiency. The aim is to evaluate the feasibility, effectiveness, and scalability of PLF interventions in resource-constrained settings and to provide policy-relevant recommendations for technology diffusion and extension services. Specific objectives are (i) to develop a low-cost PLF prototype integrating sensor-enabled feeders, a mobile app, and cloud-based analytics; (ii) to assess user acceptance, usability, and behavioral determinants of adoption among 350 smallholder farmers selected through stratified sampling across three districts; (iii) to quantify changes in animal performance metrics (weight gain, feed intake, and feed efficiency) over a 120-day production cycle using controlled farm groups and matched controls; (iv) to identify technical and socio-economic factors influencing system reliability, data quality, and decision-support accuracy; (v) to model the economic return and risk profile of PLF deployment under varying input costs and market scenarios; and (vi) to formulate a scalable implementation framework incorporating training, maintenance, and policy implications for rural development. The study employs a mixed-methods research design anchored in pragmatism. Quantitative data will be collected from 28 smallholder farms implementing the PLF system and 28 matched comparison farms over a single production cycle. Data sources include feeder sensor logs (feed dispensed, refusals, daytime vs. nocturnal activity), biometric devices for growth tracking, farm records (costs, mortality), and app usage analytics. Descriptive statistics, repeated-measures ANOVA, and multilevel regression will examine treatment effects on growth performance and feed efficiency, while propensity score matching will control for baseline differences. Economic evaluation will apply partial budgeting and Monte Carlo simulations to estimate net present value, internal rate of return, and risk-adjusted profitability. Qualitative data from semi-structured interviews (n=40) and focus groups (n=12) with farmers, extension agents, and local technicians will be analyzed thematically to elucidate adoption drivers, perceived value, technical challenges, and socio-cultural barriers. Theoretical framing will integrate the Technology Acceptance Model (TAM) and Diffusion of Innovation (DOI) theory, complemented by the Resource-Based View (RBV) to interpret capability development and competitive advantage from PLF deployment. Anticipated findings indicate that real-time, individualized feeding informed by sensor data can reduce average daily feed intake without compromising weight gain, improving feed efficiency by 8–15% and reducing feed costs by 6–12% under typical smallholder constraints. System reliability is expected to improve with robust data validation protocols and local technician support, while user acceptance will hinge on perceived usefulness, ease of use, and affordability, moderated by literacy and digital familiarity. Economic analyses are projected to reveal positive net benefits within 18–24 months in most scenarios, with sensitivity analyses highlighting higher returns when cooperative procurement and shared maintenance are adopted. The study will identify critical enablers and barriers to scalability, including 1) affordability of sensors and data plans, 2) training quality and ongoing technical support, 3) integration with existing farm records, and 4) alignment with local extension services and credit access. The contribution to knowledge includes empirical evidence on the performance, economics, and sociotechnical determinants of PLF in smallholder systems, methodological insights into the integration of sensor-driven nutrition with mobile decision-support in low-resource environments, and a practical framework for scalable deployment. The findings will inform policymakers, development agencies, and technology providers about design features, business models, and policy instruments necessary to promote sustainable intensification of smallholder livestock farming through ICT-enabled precision feeding.

Thesis Overview

Smartphone-based Precision Livestock Feeding in Smallholder Farms is about using mobile technology to tailor livestock feeding to the needs of individual animals or small groups on small farms. The aim is to improve feed efficiency, animal growth, and overall farm profitability while reducing waste and environmental impact. Why it matters: Smallholder farms typically rely on generic feeding practices, which can waste feed, increase costs, and limit productivity. Smartphone-based precision feeding can provide real-time guidance using simple data inputs, enabling farmers to adjust rations based on factors such as age, weight, production stage, and observed behavior. This approach has the potential to make livestock management more accurate, scalable, and accessible in rural settings where veterinarians and extension services are scarce. What problem or knowledge gap it addresses: There is limited empirical evidence on the feasibility, accuracy, and farmer acceptability of smartphone-driven precision feeding in diverse smallholder contexts. Gaps include how to integrate easily collectible farm data, how to translate algorithms into practical on-farm decisions, and how to measure impacts on feed efficiency, growth, and cost savings. What the researcher will do (step by step): - Conduct a literature scan to identify current precision feeding models and smartphones’ role in smallholder contexts. - Design a mixed-methods study combining a pilot intervention with a smallholder dairy or fattening setup of about 60–100 farms over six months. - Develop or adapt a user-friendly smartphone app that prompts data entry on animal identifiers, weight estimates, age, feed types, and daily intake, plus optional sensor data. - Train farmers on data collection and app use; provide technical support during the study. - Collect quantitative data on feed intake, weight gain, feed costs, and conversion efficiency; gather qualitative feedback through farmer interviews and focus groups. - Analyze data using regression analysis to identify factors predicting improved feed efficiency; use ANOVA to compare pre- and post-intervention outcomes; perform thematic analysis on interview transcripts to capture user experience and barriers. - Synthesize results to assess technical feasibility, economic viability, and scalability, and propose guidelines for broader deployment. Expected contributions and outcomes: The study will provide empirical evidence on the viability of smartphone-based precision feeding in smallholders, identify drivers of success and barriers to adoption, and offer a practical framework for implementation. Anticipated outcomes include improved feed efficiency metrics, reduced feed costs, and a set of recommendations for policy, extension services, and app-oriented farmers’ training.
