The effect of feeding maize-based concentrates on milk yield in cows with cost-benefit analysis was done at smallholder farms in four districts of northern Bangladesh. Concentrate mixtures containing wheat bran, rice polish and sesame oil cake were supplied to 40 indigenous ( Desi ) cows (20 in Group A and 20 in Group B) for 30 days before intervened feeding. Cows were given 1 kg maize-based concentrates/100 kg body weight twice daily for a further 60 days after feeding intervention. Cows' body weight, milk yield and farm income were recorded before and after maze-based concentrate supplementation. Milk production is increased by 30% for Group A and 90% for Group B. The difference in milk yield before and after supplementation of maize-based concentrate in Group B was significant (P<0.05). The cows' average body weights in Group A increased by 4.7 kg and in Group B by 1.8 kg. In both groups, net income increased and the income increase in A was significantly (P<0.01) greater than in B. Maize-based concentrated feeding in cows led to better milk yield with good economic return. DOI: 10.3329/bvet.v26i2.4950 Bangl. vet . 2009. Vol. 26, No. 2, 48-53
