On July 9, 2024, the North Dakota Monitor reported that Riverview plans to build two large confined dairies in North Dakota: a 25,000-head dairy near Hillsboro in Traill County and a 12,500-head dairy near Wahpeton in Richland County. Total investment in the Traill County dairy is expected to be $180 million and will create about 100 jobs, while the investment in the Richland County dairy is expected to be $90 million and require about 45 jobs. The full article is at https://northdakotamonitor.com/2024/07/09/huge-dairy-farms-planned-for-eastern-north-dakota/.
Needless to say, these investments will provide incredible opportunities for these communities, especially for local farmers who will be providing most of the feed needed to support them. To provide some perspective about the scale of the feed requirements of these two dairies, I have made some rudimentary calculations of how much feed will be needed each year to support both dairies and an estimate of the feed value.
Table 1 reports the expected feed requirements by ingredient on a pounds-per-cow-per-year basis for a modern confined dairy managing cows expected to produce an average of 24,000 lbs. of milk per cow per year (typical for such dairies). For my calculations, I used the quantities of individual feed ingredients for a typical ration for cows in a conventional confined dairy published by University of Missouri Extension, which is at https://extension.missouri.edu/publications/g676.

Riverview’s diets may vary some from those reported in Missouri. For example, Riverview might use barley silage instead of whole cottonseed. Nonetheless, this data will give us a good idea about the magnitude of the total feed ingredients needed each year for a typical dairy ration used in a confined dairy. The data include quantities of individual ingredients for the time of year when cows are lactating and for the period when cows are dry. Also, I do not include feed requirements for replacement heifers being developed in-house because large dairies typically have their heifer calves developed off-farm, which is the practice that Riverview follows, as I understand it.
In Table 2, I report for each location total quantities of each feed ingredient on a tons-per-year basis and the corresponding values of each feed ingredient based on prices from various USDA market reports for August 2024. The magnitude of these values is incredible and provides useful information to farmers about the sheer scale of the feed these two large dairies will require. These values are based on one set of prices for the various feed ingredients. Without a more detailed evaluation, it is difficult to say if this set of prices reflects a long-term average. However, in any case, when prices are higher than average, the values of feed will also be higher, and in instances when prices are lower than average, the values will be lower. Either way, the magnitude of the value will be significant.

The Hillsboro dairy plans to have a 25,000-cow herd and the Wahpeton dairy will have a 12,500-cow herd. Quantities reflect cows that are expected to produce, on average, 24,000 pounds of milk per head per year.
* Prices of feed were obtained from various USDA market reports on Aug. 25, 2024.
A good deal of coproduct feed from corn ethanol and soybean crush plants will be needed (i.e., 8,893 tons of DDGS, 12,698 tons soybean meal and 7,049 tons of pelleted soybean hulls), providing for a new alternative market for those products that have a value somewhere in the neighborhood of $4.3 million annually.
In addition to the opportunity for local producers to market their feed directly (or, in some cases, indirectly) to these two large dairies, there is potential benefit for local producers to obtain nutrients in the form of cow manure to put back on some of their cropland acres. In an upcoming article, I will attempt to calculate the quantity of manure that will be available and provide an estimate for how many acres the annual supply of manure can be applied to each year.
