If feed is available at all times cows can get by with 18 inches of bunk space. 4) Feed lower quality forage to the dry cows or the cows in late lactation and the good quality forage to the cows in early lactation. cow, 3 lb. Barley processed to a smaller particle size improved starch digestion and feed efficiency in cattle fed medium-concentrate growing diets. livestock production to forage and farm management resources. Corn grain endosperm type and brown midrib 3 corn silage: Feeding Behavior and Milk Yield of Lactating Cows. Grass silage and hay have a very wide range of NDF digestibility because grass species are so diverse and are utilized at extreme ranges in maturity (e.g. Faith Cullens, Michigan State University Extension - July 30, 2012. Corn Drought can cause nitrates to form in corn plants, especially in lower stalks. Corn silage stores the nutritional value of corn plants for a prolonged period of time and improves cattle productivity with the necessary protein, energy and the digestive capability of corn, keeping its initial properties intact. Reduced NDF digestibility; Decreased milk production. Finally, a number of producers are looking at limit feeding corn silage mixed with ground corn stalks or poor quality hay. First of all the level of corn silage in the ration has a major impact on how cows will adjust when new corn silage is introduced. Many producers value corn silage for its protein contribution. Sometime in the 60s cattle growers realized that if they stuffed corn - which is not a natural feed for bovines - into young animals they were able to digest it and gain mass rapidly. But in terms of net income, the perennial forage herds brought in an additional $184 per cow. Transitioning new corn silage into the diet can impact milk production and cow health.
