With all the moving parts on a dairy farm, many would think that determining ration costs would be a relatively easy endeavor. The industry also has many experienced and knowledgeable nutritionists to assist in this effort.
Dairy steers contribute 15 to 20 percent of the fed beef market in the U.S. The economic variables that affect profitability of feeding Holstein steers from 6 months old to finish are similar to those of feeding beef cattle.
In intensive dairy production, feed costs represent up to 60 percent of the total cost of producing milk. Continuous improvement in dairy efficiency is vital to the success of the dairy enterprise. Reliable and rapid feed analyses are therefore required to accurately assess the availability of energy and nutrients of feeds.
Twenty billion dollars. We feed $20 billion of feed to dairy cattle in the U.S. every year. We have highly sophisticated programs that can tell to the milligram how much iodine should be fed.
Forage will always be an important and key point of dairy nutrition. With constant fluctuation in forage quality crop-to-crop and year-to-year, it can be perplexing to try to determine how cows will respond.
As a supporting consultant working with thousands of dairy consultants, three key questions continue to re-emerge relating to forage quality and change.
Today, through advancements in nutritional science, we know more precisely what goes on inside the cow. That gives us the opportunity to manage the smaller pieces of the nutrition puzzle – protein fractions instead of crude protein – and to build a more precise diet to optimize cow health and performance.
Increasing nitrogen efficiency and income over feed costs (IOFC) represent goals nutritionists and dairymen alike strive for. In April 2015, the cost of metabolizable protein was $0.64 per pound for the Midwest U.S.
For a cow producing 80 pounds of milk at 3.1 percent milk protein, this represents a nutrient cost of $3.59 per day. The question of whether protein supplementation can be reduced or optimized to improve IOFC should routinely be considered.
The science of dairy cattle protein intakes and the subsequent milk protein production has evolved significantly since amino acid balancing became an important nutrition strategy on dairy farms.
While the industry has come a long way, current and future research in this field will further advance its effectiveness in putting high-value components and pounds of milk in the bulk tank.
Dairy efficiency is a commonly used term and is defined as either milk output per unit of dry matter intake or energy-corrected milk output per unit of dry matter intake. The problem with this measurement is that it is influenced by the energy density of the ration, among other factors.
As a dairy producer, it’s important to know what is happening in your dairy’s nutrition program. Common questions related to amino acid balancing include the following.
