To investigate the effects of feed intake adjustment in early lactation on milk yield of dairy cows raised at small holders, one completely randomized design (CRD) experiment was conducted in Nghe An province. Two groups, each included 5 cows, were used to compare the effects of 2 feeding regimes: average existing ration (Control) and average existing ration plus 6 adjusted concentrate meals (rreated). The treatment was lasted for the first 5 weeks of lactation. The results show a significant increase (P0.001) in feed intake when concentrate was fed 6 times a day. Consequently, compared to control animals, treated cows produced a significant higher milk yield (17.53 vs. 14.48 kg, with P0.001), an earlier (1 week) and greater (20.44 vs. 16.60, P0.05) peak value. The improvement in body condition score (BCS) was observed in treated cows, but the significance was low (P 0.05). The continuous higher milk yield of treated cows in 5 weeks after treatment clearly indicates a carry-over effect achieved by the adjusted feeding regime. This study implies that offering 6 concentrate meals a day could positively increase feed intake and therefore improve the performance of dairy cows in early lactation.
