The focus of this review is to offer an overview of food and nutritional security, to identify associated constraints, and propose possible alternative solutions for improving the East African poultry sub-sector in the pursuit of food security, focusing on chicken breeding. To better understand the prospects of the poultry industry, we highlighted and combined confirming evidence of the phenotypic variability and genetic diversity of East African chicken genetic resources using both morphological and molecular tools, as well as performance traits. Furthermore, this work gives a detailed indication of what would be lost if indigenous chicken populations are left to suffer the ongoing massive genetic erosions due to various factors, not limited to indiscriminate crossbreeding. Previous and recent attempts to improve the productivity of indigenous chicken are highlighted, and possible future breeding plans and areas of immediate research are suggested as well. This review concludes that under the prevailing conditions, the village chicken production system appears to be the most imperious production system that needs to be extensively developed ; however, for the sustainability of the industry, the proposed improvement strategies should create a permanent balance between the competing needs of genetic improvement and the genetic diversity of the indigenous chicken genetic resource.

Africa is home to a wide diversity of locally adapted pig breeds whose genetic architecture offers important insights into livestock adaptation to climate change. However, the majority of these inherent traits have not been fully highlighted. This review presents an overview of the current state of African pig genetic resources, providing highlights on their population and production statistics, production system, population diversity indices, and genomic evidence underlying their evolutionary potential. The study results reveal an incomplete characterization of local pig genotypes across the continent. The characterized population, however, demonstrates moderate to high levels of genetic diversity, enough to support breeding and conservation programs. Owing to low genetic differentiation and limited evidence of distinct population structures, it appears that most local pig populations are strains within larger breeds. Genomic evidence has shown a higher number of selection signatures associated with various economically important traits, thus making them potential candidates for climate change adaptation. The reportedly early evidence of hybridization with wild suid groups further suggests untapped insights into disease resistance and resilience traits that need to be illuminated using higher-density markers. Nevertheless, gene introgression from commercial breeds is prevalent across Africa; thus, efforts to realize and utilize these traits must increase before they are permanently depleted.

The role that genetic diversity in animal genetic resources (AnGR) plays in mitigating the effects of climate change on the global protein supply is of the utmost significance. East Africa historically played a pivotal role in the dispersal of domesticated livestock species across the African continent. At present, it maintains a substantial contribution to worldwide biodiversity as a result of its reservoir of a diverse array of AnGR, characterized by genetic and species diversity. A considerable reduction in the genetic diversity of AnGR has been documented in numerous studies, giving rise to concerns regarding the sustainability of animal protein supply in the face of climate change. The objective of this article is to outline prospective roles that advocacy and management organizations specializing in AnGRs may undertake to aid in the conservation of AnGR genetic diversity in East Africa. Moreover, it provides a prospective framework and structure for advocacy that extends from the farmers, to the higher-level (regional farmers association). We believe that advocating for the promotion of genetic diversity at the regional level will have a significant impact at the national and further at global scale.
