One of the perennial issues in Nigeria’s Agricultural sector is the tension between Nigeria’s pastoralist herders and the settled indigenous farmers. These tensions have intensified in the country in recent years, particularly with the heightened insecurity in Northern Nigeria, dwindling natural resources, and unavailability of enough grazing land; all contribute to the migration of the herders from the Northern part of Nigeria to other parts of the country. Thus, with a focus on the effects of migration and the herders-farmers clashes on milk production, our team interacted with farmers and herders in selected communities in South-western Nigeria in Ondo, Osun, and Oyo States. The methodology for data gathering included- descriptive research, field survey, qualitative interviewing, and the use of relevant journal articles. The major findings indicated that the herders migrate primarily for cattle grazing, sometimes this grazing encroach on farmlands, and causes the conflicts with farmers. The major effects on the cattle include low dairy production due to stress, soft tissue injuries, attacks from reptiles and farmers, cow disease and sometimes, death of weak cattle. This study recommends the need for nomadic education, ranching of cattle, cattle health policies, and adequate cattle grazing systems as obtainable in civilised societies.
