Abstract
<p>African animal genetic resources are diverse and have been the subject of crossbreeding for decades to improve local livestock and poultry populations. However, the literature on crossbreeding performance has been inconsistent, with many projects failing due to various reasons. This has led to mixed support and criticism for crossbreeding in small-scale animal agriculture. The review examines the achievements, problems, and future prospects for livestock and poultry genetic improvement through crossbreeding in Africa’s small-scale animal agriculture. Community-based Breeding Practices (CBBP) can be seen as a community livestock development strategy that mobilizes local animal genetic resources and boosts smallholder livestock producers’ ability to collaborate in resource-scarce communities. Genome sequencing is seen as the future cornerstone of promoting crossbreeding in Africa, but it should be based on consideration of the socioeconomic context of small-scale animal husbandry and local livestock production conditions. Smallholder farmers, who are the major custodians of local animal biodiversity, have faced challenges such as genotype and environmental interaction, lack of funding, poor laws, and lack of farmer participation. In conclusion, the review highlights the importance of phenomics and genomic prediction in improving animal genetic resources in Africa, but it also emphasizes the need for further research and development in this area. The study suggests that modern breeding technologies (genomics and phenomics) and training of smallholder livestock farmers in improved animal husbandry management practices can be used to enhance food and nutrition security for African rural households. This review examines the effects of crossbreeding through the decades on small-scale livestock farming in Africa, including positive and negative outcomes as well as future implications.<strong></strong></p>
