Abstract

This study was conducted to evaluate the effects of intake of alfalfa and tifton-85 hays and corn silage on the milk production and composition of multiparous Holstein cows, averaging 460 kg in body weight, at the beginning of lactation, using a triple Latin square, simultaneous, with three lines (cows) and three columns (forages). There was no effect (p > 0.05) of the different types of forage on the milk production and composition, or on the percentage the production of fat, protein, lactose, total solids, and somatic cell count. The results of the economic analysis showed that the corn silage provided a larger liquid margin for liters of milk produced per day.
