The dry seasons decline in milk production due to insufficient feed supply to dairy cattle poses a great challenge to sustainability of smallholder dairy production systems in Tanzania. Locally produced leguminous fodder tree leaf meals combined with maize bran provide a great potential for overcoming the dry season protein-energy deficit in the basal roughage feeds. This study evaluated the effects of dry season Calliandra calothyrsus (Calliandra) leaf-meal: maize-bran based protein-energy homemade supplementary ration (HSR) on milk production of lactating cross-bred dairy cows in the Western Usambara Highlands (WUHs), Tanzania. Complete randomized design was employed whereby four groups of 4 lactating dairy cows were subjected to four levels of HSR rationed at 0, 2, 4 and 6 kg/cow/day. The lactating cows which were not subjected to HSR supplementation (0 kg/cow/day) were left under farmers’ feeding practices as a control. HSR had significant effect on dry season milk yields (P |
