Technical Abstract: Silage is an integral ingredient in the diets of lactating dairy cows in temperate regions of the world. In North America, silages formulated into the diets of high-producing dairy cows are predominantly corn silage and alfalfa silage along with smaller usage of other forages such as small grain silage and grass silage. Different challenges exist for different forages crops that are ensiled. These challenges affect how dairy nutritionists utilize these silages in the diets of high producing dairy cows. Challenges include finding the best way to utilize the nitrogen provided by the silage without losing it as waste and how to best utilize the carbohydrates in forages through improved ruminal digestibility. Overall, the goal as a dairy nutritionist is to utilize as much forage as possible in the diet without limiting intake, and ultimately, to improve milk production.
