About Journal

The Nigerian Journal of Animal Science (NJAS) is an official publication of the Animal Science Association of Nigeria (ASAN) that is published twice a year in two issues. The Journal publishes carefully peer-reviewed original research articles on various farm and laboratory animals covering diverse areas such as production, management, health, physiology, nutrition, feeds and feedstuff, breeding and genetics, reproduction, animal products, biotechnology, socio-economics, extension, farming systems and crop/livestock interactions within the context of sustainable livestock production among others. Review articles should cover new development in a field of livestock production.
