This manual provides a set of conceptual definitions and practical implementation protocols for knowledge and scaling hubs. Both concepts of knowledge and scaling hubs are developed to aggregate, leverage, and coordinate the efforts undertaken by pilot research project with larger development programs and local scaling dynamics.

Genetic improvement on local breeds kept by small farmers in developing countries is challenging. Even though good pedigree and performance recording is crucial and an important component of breeding programs, it remain difficult or next to impossible under conditions of subsistence livestock farming. This means that standard genetic evaluations, as well as selection and planning of mating based on estimates of the animals' genotypes, cannot be done at any level in the population of the target breed or genetic group.
