Item Diversifying Energy and Protein Sources for Poultry Feeds in Kenya(Science Publishing Group, 2023-09-27) Wachira, A.; Mwangi, M.; Nyingi, D.; Minyatta, E.; Muriuki, W.; Kenya Agricultural and Livestock Research Organization (KALRO) Non Ruminant Research Institute, Kakamega, Kenya.

Kenya Agricultural and Livestock Research Organization (KALRO) Non Ruminant Research Institute, Kakamega, Kenya. Centers for Research and Data Technologies (CRDT), Nairobi, KenyaThis study explores the utilization of alternative and locally available energy and protein sources in laying chicken feed formulations, aiming to reduce costs, enhance availability, and promote climate-smart approaches. The experiment included five dietary groups, each with specific energy and protein sources. Significant results emerged: average live weights displayed statistical significance (p < 0.0001), with hens on diet A3 containing fish meal (omena) exhibiting a moderate weight increase. Weekly egg collection demonstrated significance (p < 0.0002), with diet A3 yielding the highest collection, while A5 (positive control) produced the lowest. These trends mirrored the percentage lay, emphasizing diet's role in egg production. The incorporation of fish meal in diet A3 stood out, influencing growth rates and egg production due to its nutrient density and balanced amino acids. The impact of diets on egg weights was significant (p<0.0001), and feed consumption varied (p<0.0001), influenced by factors such as palatability and nutritional balance. The Feed Conversion Ratio (FCR) analysis highlighted diet differences in feed efficiency. Overall, the study highlights the intricate interplay between dietary compositions, poultry performance, and production metrics, emphasizing the importance of well-balanced, diverse, and climate-smart feed formulations in achieving sustainable and efficient chicken production.Item Strategies for Transforming the Poultry Industry in Kenya Through Participatory Modelling(Science Publishing Group, 2023-06-09) Wachira, A.M.; Muriuki, W.; Nyingi, D.W.; Kenya Agricultural and Livestock Research Organization (KALRO) ; Centers for Research and Data Technologies (CRDT) ; Veterinary and Animal Production SolutionsSustainable development of the poultry industry in Kenya can significantly contribute to economic growth while also improving the livelihoods of millions of people who keep poultry for a living. To achieve this impact, strategies that will advance the industry across all value chain segments are required. In this study, we developed strategies to transform the Kenyan poultry industry through a system dynamic modelling, participatory approach that included Focus Discussion Groups (FDGs) and Key Informant Interviews (KII), with the findings validated through a workshop. These findings are depicted in causal loop diagrams to show how the proposed poultry industry's elements interact in a systematic manner. Using this methodology, it was observed that strengthening socioeconomic factors such as legal framework in associations and cooperatives can significantly improve the industry. The legal framework can provide a clear and stable environment for the operation of these organizations, helping to ensure that they function efficiently and effectively. This, in turn, can improve the competitiveness and sustainability of the poultry industry, as well as support the growth and development of the wider economy. Having a strong legal framework can help to ensure that the rights and interests of producers and other stakeholders are protected, which can increase trust and confidence in the industry. This can lead to greater investment and collaboration and can support the development of new and innovative solutions to the challenges facing poultry value chain actors. Additionally, modern technologies, innovations, and management practices can play a crucial role in improving efficiency along the value chain. These innovations can help to increase productivity, reduce costs, improve the quality and safety of poultry products, and meet the changing needs and preferences of consumers
