Performance of local and local x improved chicken crosses under semi-intensive management system in Northern Uganda

Abstract

Despite the efforts to improve Uganda’s chicken production through crossbreeding, limited research has been conducted to establish the performance of local x improved chicken crosses under the dominant management systems used by chicken rearing households. The current study aimed to assess the performance of local x improved chicken crosses under semi-intensive management system in Pader and Agago districts of Northern Uganda, where crossing of local with imported Kuroiler chickens has been promoted over time. A cross-sectional survey using a semi-structured pre-tested questionnaire and observation was conducted in two purposively selected sub-counties per district among 246 respondents to establish the sociodemographic characteristics of chicken farmers and reasons for crossing. Using a Completely Randomised Block Design, an experiment was set up to compare the performance of local chickens and local x improved chicken (Kuroiler) crosses in terms of egg production and hatchability. All respondents practiced crossing with the aim of enhancing egg production in their chicken flocks. Under semi-intensive management system, the hatchability of the eggs from crossbred chickens did not differ (P ≥ 0.05) from that of the eggs laid by the local chickens. In conclusion, although crossbred chickens exhibited hybrid vigour in terms of egg production under free-range and semi-intensive systems, the hatchability of the eggs from crossbred chickens raised under semi-intensive systems did not differ from that of eggs from local chickens. Future research should consider establishing the quality attributes of eggs of the local x improved chicken crosses in the dominant management systems among chicken-keeping households in Uganda.
