In the 13 years that the feedlot school has been held, there have been 20 different schools that provided information to over 500 participants, with some repeat participants. The sessions are held annually at the Carrington Research Extension Center during late January. The same basic school has been offered at other locations some years, including Fargo, Hettinger, Williston, and Sidney, Montana. A feedlot school was offered in Maine modeled after the NDSU program, and a college course and training certification program in Colby, Kansas, was spurred by the NDSU Feedlot School. The program has reached producers in eight states and one province including South Dakota, Montana, Nebraska, Minnesota, Wisconsin, Oregon, Maine, and Manitoba. An evaluation is given at the end of every school that asks participants for honest feedback. The curriculum is adapted to producer needs based on these responses and has evolved over the years of the school. According to the most recent North Dakota Agriculture Statistics Service Feedlot Survey (2008), from 2004 through 2007 the total number of feeding operations with 500 head or more capacity, has increased 16% from 130 to 151 feedlots. Total capacity has increased 20% from 189,000 to 226,300 head. The future of the North Dakota Feedlot School is to continue with the ongoing interest of the producers. Planning is underway for an ―advanced‖ feedlot school for those that want a deeper understanding of nutrition, marketing, and management. The goal is to provide the utmost quality programming that makes the North Dakota State University Feedlot School partnership successful. With the increasing interest in feeding cattle to slaughter weights in the Northern Plains, and the ample supply of cattle, feed grains, forages, and co-products for feedlot use across the area, the North Dakota Feedlot School has helped producers increase their working knowledge of feedlot operation. In addition to the material presented, the school serves a function to network feeders and faculty for future communications. All of the principles taught in the school are relevant to other regions as well and serves any area interested in feeding cattle. This program requires extensive collaboration between cooperating agencies, industry, and private operators all with the intent to make the cattle feeding business better for all parties involved.

Observations on the Palatability of an Inorganic Salt Product for Mitigation of High Sulfur Levels in Feedlot Diets V.L. Anderson 1 , B.R. Ilse 1 , P. Gruel 2 and S. McLeish 2 1 NDSU Carrington Research Extension Center 2 Sartec, Inc. Introduction Distillers grains are often the lowest cost protein feed available for cattlemen. This ingredient can be used in cow/calf production as well as feedlot diets. However, distillers grains often contain high levels of sulfur. There is significant variation in the sulfur content of distillers grains from plant to plant and even within a plant as sulfuric acid may be added to batches to improve fermentation efficiency by altering the pH. Sulfuric acid is also used to clean equipment. While sulfur level is often between 0.65 and 0.85% on a dry-matter basis, levels as high as 1.25% sulfur have been analyzed. Beef cattle can tolerate a maximum of 0.40% sulfur in the diet (NRC, 1996) before polio-like symptoms of sulfur toxicity are generally observed, with the first noticeable sign often being death. Toxic symptoms and death have been reported when a diet contains as low as 0.25% sulfur in grain-based diets. Grain diets are thought to be less tolerant to high sulfur levels but with forage diets, sulfur tolerance may be greater. It is unknown how many health and reproductive problems have occurred due to sub acute sulfur toxicity from feeding distillers grains, high-sulfate content water, or sulfur in other feed sources. Survey data may be inconclusive due to the unwillingness of producers to admit to these losses, or inconclusive diagnosis by producers or their veterinarians. Any feed ingredient or management technique that would mitigate sulfur toxicity and allow increased use of distillers grains with less potential for illness or death will be well received in the livestock industry. New feed products are under development that may tie up sulfur and reduce negative effects of higher sulfur levels in the diet of cattle. The objective of this field study was to determine the effect of adding a proprietary inorganic salt product to feedlot finishing diets on feed intake, gain, and carcass traits. Experimental Procedures Forty-eight Angus feeder calves were blocked by sex (heifers and steers) and assigned within block to one of two treatments. One pen of steers and one pen of heifers were fed the proprietary inorganic salt product developed to mitigate sulfur levels in feedlot rations. The second pen of steers and heifers was fed the same diet without the inorganic salt product. The inorganic salt product was fed at 13.8 grams per head per day based on recommendations of the manufacturer. This product was mixed into the feedlot supplement (Table 1) which was added to the grain component of the ration in the daily ration preparation. The supplements were manufactured at the Northern Crops Institute (NCI) on the campus of NDSU under the direction of Dr. Kim Koch, manager of the NCI Feed Production Center. Supplements were transported to the Carrington Research Extension Center in tote bags. Supplements were formulated to be fed at 0.33 pounds per head per day, and contain minerals, vitamins, Rumensin (300 mg/hd/d), and carrier feed products (Table 1). Supplements were formulated to be identical except for the addition of the inorganic salt product. Page 7 2009 NDSU Beef Feedlot Research Report
