Over the past couple of decades, advances in forage genetics, forage agronomics, forage harvesting and ensiling have enabled dairy farms to feed progressively more forages as a percentage of their total lactation ration. Feeding higher amounts of high-quality forage has resulted in improved rumen health, improved cow health and higher milk components. Another benefit of feeding higher levels of high-quality, homegrown forages is that it often translates to lower purchased feed costs and improved income over feed cost.
