The Nigerian Journal of Animal Science (NJAS) is an official publication of the Animal Science Association of Nigeria (ASAN) that is published thrice a year. 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. Submission of a paper will be taken to imply that the material has not been previously published or is being considered for publication elsewhere. Conference papers may however, be upgraded after conforming to journal guidelines. NJAS does not necessarily subscribe to the opinions/conclusions expressed by authors however; copyright of all published material rests with the journal.
