Three on-station experiments, one survey and two on-farm studies were undertaken in Matabeleland South Province, Zimbabwe. The objective was to assess the effect of feed supplementation and breed on reproductive performance and milk yield in cows bred for use in the smallholder dairy sector. The studies demonstrated that feed supplementation was beneficial in improving reproductive performance and milk yield of cows in smallholder farming sector. In addition, crossbred cows were superior to indigenous cows in terms of reproductive performance and milk yield.
