Long term genetic gains implementation planRaphael Mrode, Tadelle Dessie,Hans Komen, Olivier HanotteSecond ACGG Program Management Team Meeting, Arusha, 27-28 January 2016African Chicken Genetic GainsVision• Sustainable genetic improvement program can be primary driver for change• GET the genetics right and it will serve as a systemic pull factorWorkplan• Evaluate promising indigenous chicken ecotypes• Design and evaluation of breeding schemes• Outline path forward for sustainable genetic improvementEvaluating the chicken strains/ecotypesBased on the on-field or on-station trials:• Select about 2 indigenous chicken ecotypes within country• Select about  2 preferred ecotypes  from the  imported strains• Expectations from countries• Adequate data available on tested strains:• On characteristics of economic importance• Genetic parameters can be estimated from the data• Breeding value estimationDesign and evaluation of breeding schemes• Primary aim is to maximize genetic gain while controlling the rate of inbreeding• Breeding schemes will therefore be evaluated (data analyses & simulation)  – Appropriate effective population size– Traits to be selected for to ensure long term sustainability  (productivity, survivability, fertility, etc)– Optimum contribution to manage rate of inbreedingDesign and evaluation of breeding schemes– Setting up different lines such as maternal line or paternal lines either in within strains and across strains– A cross as the final commercial productCollaboration with the Center for Tropical Health and Genetics  to benefit from latest genomic and genetic advancementsOutline path forward for sustainable genetic improvement• Involvement of the Public Private Partnership to own the programme– Demonstrate to PPP a sustainable breeding scheme has put in place or is feasible• Multiplication and distribution  by the PPPCurrent Status• A document outlining the long-term genetic gain in detail is being finalized• Collaboration is crucial• Important to meet needs of farmers• Focus on impact: pathway out of povertyGetting it rightmore productive chickens for Africa’s smallholdershttp://africacgg.netThe presentation has a Creative Commons licence.
