An ILRI-led project dubbed “Tanzania Dairy Genetic Project (AgriTT)” is being implemented in Lushoto and Rangwe districts in Tanzania in efforts to improve breed composition of hitherto indigenous dairy cattle that are unsuitable for most environments in the country. These environments, combined with poor dairy management practices results in low milk production. Currently, farmers-led initiatives to improve the situation have revolved around cross-breeding indigenous animals with higher producing ones. However, due to the absence of a breeding and mating strategy, resulting breed composition of these animals is unknown, making it extremely difficult to improve low milk yields. The project seeks to find and transfer knowledge on dairy cattle genotypes that will help farmers identify dairy breeds most suitable to farm environments thus increasing their yields.
