High Moisture Corn for Dairy Cows in Early Lactation

Abstract

Two trials were conducted to evaluate high moisture (HM) corn as the primary concentrate energy source for dairy cows in early lactation. In Trial I, thirty-six Holsteins compared I.IM shelled corn, dry shelled corn, and a multi-ingredient pelleted dairy concentrate. In Trial II, thirteen Holsteins and three Ayrshires compared HhI shelled corn and HM ear corn. Soybean meal was added to each corn. In both trials, conducted for 16 weeks after calving, grain was fed in an attempt to maintain postpartum body weight. Forages, including hay, corn, and gras.~ silages were offered ad libitmn.
