Effectiveness of Improved Livestock Breed Initiatives on Productivity and Household Profitability in Kiminini Ward, Trans-Nzoia County, Kenya

Abstract

Livestock production is a cornerstone of rural livelihoods in Kenya, contributing approximately 12% to the national GDP and supporting over half of the agricultural labour force. Despite its significance, smallholder productivity remains constrained by genetic limitations and inadequate management practices. This study evaluated the effectiveness of improved livestock breed initiatives on productivity and household profitability among smallholder farmers in Kiminini Ward, Trans-Nzoia County. Using a cross-sectional research design, data were collected from 180 households (90 adopters and 90 non-adopters) through a multistage sampling procedure. The study employed descriptive statistics and Ordinary Least Squares (OLS) regression models to estimate the impact of breed adoption while controlling for household demographics, institutional access, and farm characteristics. The findings reveal that adopters achieved an average milk yield of 15.2 litres/cow/day compared to only 3.8 litres/cow/day for non-adopters, representing a fourfold increase in productivity. However, adopters incurred significantly higher production costs (KES 95,000 vs. KES 40,200 annually), resulting in a net income of KES 90,000 for adopters versus KES 38,300 for non-adopters. While profitability is higher among adopters, the profit margins are highly sensitive to input costs and management efficiency. Access to extension services and market linkages were identified as critical determinants of successful adoption. The study concludes that while improved breeds effectively overcome biological productivity constraints, their economic viability hinges on complementary support services. Policy interventions should prioritize strengthening extension systems, subsidizing quality feed inputs, and enhancing market infrastructure to ensure that productivity gains translate into sustainable household welfare improvements. This micro-level evidence provides actionable insights for policymakers and development partners seeking to enhance the livestock sector's contribution to Kenya's agricultural transformation agenda.
