The aim of this trial was to study the effects of different levels of maize supplementation on milk yield and milk composition of grazing cows. The trial lasted for 10 weeks (4th-13th week of lactation) beginning in Oct. 1986. 18 Argentine Friesian cows grazing a pasture of ryegrass and white clover were assigned to the following treatments: T0: 0 kg maize; T1: 4 kg maize; and T2: 8 kg maize.
