Abstract

A trial was carried out with objective of identifying economical sources of alimentary supplementation for cows milk in exclusive feeding regime of elephant-grass pasture (Pennisetum purpureum cv. Napier), submitted to the fertilization and irrigation. The experimental design was completely randomized with three treatments: T1 = cows grazing exclusively in elephant-grass pasture; T2 = T1 + bank of leucena protein and T3 = T1 + concentrated ration, supplied in the amount of 1 kg for each 3 kg of milk produced above 5 kg. The largest production milk was obtained of the animals of T3 (11.11 kg of milk/cow/day and 3,594.08 kg of milk/cow/lactation), followed by T2 (9.19 kg of milk/cow/day and 2,740.15 kg of milk/cow/lactation) and T1 (8.54 milk/cow/day kg and 2,520.36 milk/cow/lactation kg). The lower profitability was obtained with cows grazing elephant-grass supplemented with concentrates.
