3 trials were carried out to determine the voluntary intake of maize silage, 1st-cut Italian ryegrass silage, prewilted Italian ryegrass silage and Italian ryegrass hay by dairy cows. Each trial was carried out with 15 cows of 3 different breeds for 18 weeks. Cows were fed the experimental forages ad lib. and concentrates were varied according to milk production, intake of roughage, body weight and number of lactation.
