Relative Feeding Values of Corn Silages of Different Maturities and First and Second Cutting Orchardgrass-Ladino Clover Silages for Lactating Cows

Twelve lactating Holstein cows were used to compare the feeding values of four different silages; corn harvested at the yellow ripe stage, corn at the ripe stage, and first and second cutting orchardgrass-ladino clover. A replicated 4×4 Latin-square design with 21-day periods was used. The cows were fed experimental silages ad libitum, with 1kg of concentrate per 6kg of FCM and 2kg of hay per cow daily. The principal results obtained were as follows: The silage dry matter intake was significantly (P
