Fed Cattle Basis In South Dakota, Matthew A. Diersen

SDSU Extension Extra Archives

Producers, brokers, and buyers routinely assess the value of cattle by monitoring cash and futures prices. Basis is the difference between a cash price and a futures price. Basis generally reflects the difference in local supply and demand conditions and quality differences. For a location like Sioux Falls, South Dakota, which is neither a delivery location for live cattle futures contracts nor a slaughter lo¬cation, basis also reflects transportation cost to a par deliv¬ery location. Basis expectations for future dates are usually formed from historic basis levels. Accordingly, actual basis may differ from expectations in a given month because of …

Prairie Dog Management In South Dakota, Sandy Huber, Jim Wilson

SDSU Extension Extra Archives

The black-tailed prairie dog (Cynomys ludovicianus Ord) is a native rodent found throughout the short- and mixed-grass prairies of North America. The US Fish and Wildlife Service (USDI USFWS 2006) estimated that black-tailed prairie dogs occupied about 1,842,000 acres in 2004. Of that, over 411,400 acres were located in South Dakota. Prairie dogs are clearly valuable as a component of grassland ecosystems, providing habitat to a number of plant and animal species. Prairie dogs clip vegetation short within their towns to enhance their ability to see predators (King 1955). As a result, they compete with livestock for forage on the …

Grid Marketing And Beef Carcass Quality: A Discussion Of Issues And Trends, Scott Fausti, Bashir Qasmi, Matthew Diersen

Economics Staff Paper Series (1969 - 2017)

Beef industry data suggest that improvements in carcass yield and quality grades have stagnated recently. Empirical analysis, based on USDA market reports, indicates that the share of steer slaughter volume marketed on a grid is less than industry estimates and the growth in market share has stagnated. Trend analysis of market share suggests that grid pricing has become an important marketing channel, but has not become the dominant marketing channel. The lack of industry progress toward achieving the carcass quality goals suggests that grid pricing has not captured the level of market share needed to realize the goals envisioned for …

Feeding Dairy Cows For Body Condition Score, Alvaro Garcia, Arnold Hippen

SDSU Extension Extra Archives

Changes in body weight are not a very good indicator of the nutritional status of dairy cows. For example, while the gut contents of a 1400 lb. dairy cow weigh approximately 200 lbs., the cow has a daily intake of nearly 100 lbs. of feed (fresh weight) and 160 to 240 lbs. of water (one gallon equals 8 lbs). In addition, the cow outputs over 120 lbs. of fresh manure and urine per day (NRC 2001), as well as 50 to 100-plus lbs. of milk. Thus, the ability to accurately depict actual changes in body mass via body weight measurements …

Sun-Drying: A Traditional Native American Method Of Preserving Food, Lorna Saboe-Wounded Head

SDSU Extension Special Series

Traditional food preservation methods have continued to be used among Native American tribes and communities in South Dakota. Elders teach youth about the traditional practice of sun-drying corn and wild berries through the hands-on process of working together with family. Buffalo meat was also traditionally sun-dried; this practice is now more commonly done through the use of a food dehydrator. Jerky or bapa (dried buffalo meat used in soups and stews) and sun-dried corn and wild berries are a healthy food which has traditionally provided sustenance to the Native American diet.

Sulfur In Distillers Grains For Dairy Cattle, D. Schingoethe, A. Garcia, K. Kalscheur, A. Hippen

SDSU Extension Extra Archives

Sulfur is an essential element needed by animals for many functions. About 0.15% of body weight is sulfur. It is found in the amino acids methionine, cysteine, cystine, homocysteine, and taurine; in chondroitin sulfate of cartilage; and in the B-vitamins thiamin and biotin. Methionine, thiamin, and biotin cannot be synthesized in cattle tissues, so they must be supplied in the diet or synthesized by ruminal microbes. The sulfur content of most feed sources reflects the sulfur amino acid content of the proteins in the feed. See table 1 for example sulfur concentrations for various feed ingredients.

Reproductive Fertility In Herd Bulls, George Perry, Julie Walker, Russ Daly

SDSU Extension Extra Archives

Herd bulls have a large influence on many aspects of beef operations, especially an operation’s profitability. For example, percent calf crop weaned is the single most important factor influencing profitability, and the number of cows bred during the breeding season plays the largest role in percent calf crop weaned. Therefore, an operation’s profitability is directly tied to the herd bull’s breeding ca¬pability. In addition, herd bulls supply half of the genetics to all the calves he sires; therefore, bull selection can be the most powerful method of genetic improvement in the herd. Herd bulls also influence overall herd fertility more …

Alimentación De Las Vacas Lecheras Para Condición Corporal, Alvaro Garcia, Arnold Hippen

SDSU Extension Extra Archives

Los cambios en el peso corporal no son buen indicador del estado nutricional de las vacas lecheras. Por ejemplo, mientras que el contenido de las vísceras de una vaca de 1400 lb. pesa aproximadamente 200 lbs., la vaca tiene un consumo diario de cerca de 100 lbs. de alimento (peso fresco) y 160 a 240 lbs. de agua (un galón equivale a 8 lbs). Además, la vaca elimina más de 120 lbs. de estiércol y orina diarios (NRC 2001), así como 50 a 100-o más lbs. de leche. Por tanto, la abilidad de describir de forma precisa los cambios reales …

Extending Native Winter Pasture Use With Spring Grazing Practices, A. J. Smart, R. Schafer, R. N. Gates

Research Bulletins of the South Dakota Agricultural Experiment Station (1887-2011)

Improving profitability will help sustain the economic viability of ranch operations. Feed costs typically represent well over half of annual cow-calf production costs. Two things, 1) grazing strategies aimed at increasing the proportion of feed supplied through grazing and 2) decreasing reliance on high-cost harvested forages, have the potential to improve profit.

Bull Nutrition, Julie Walker, George Perry, Ken Olsen

SDSU Extension Extra Archives

Bull nutrition is often overlooked by many producers, except when problems arise. Bulls are often managed as one group even though there may be large differences in age, size, and body condition. Seedstock producers are the primary individuals managing the development program of bulls being sold. For commercial producers, feeding programs usually include feeding purchased bull(s) from delivery until the breeding season and bulls retained from one breeding season to the next. The debate over the correct method for developing bulls is not settled: Should you develop bulls at a moderate rate of gain? Or should you develop bulls on …

Interpretation Of Water Analysis For Livestock Suitability, Dave German, Nancy Thiex, Cody Wright

Agricultural Experiment Station Circulars (1920-1915)

Good quality water is essential for the production of livestock and poultry. In South Dakota, many water supplies have naturally occurring al that may limit their use. Livestock producers that test their water supply can make informed decisions about the stability of their water for different classes of livestock. The purpose of this guide is to assist livestock producers in the interpretation of their water analysis.

Health Of The Herd Bull, Russ Daly

SDSU Extension Extra Archives

The importance of the herd bull to the reproductive performance and profitability of cow herds that utilize natural service cannot be underestimated. Health problems in a bull may result either in decreased fertility in that bull or, in the worst case, in an infectious disease that could spread to the rest of the breeding herd, with disastrous results for herd fertility. For these reasons, the health of incoming and existing herd bulls is of utmost importance.

Factors Affecting Road Mortality Of Whitetailed Deer In Eastern South Dakota, Troy W. Grovenburg, Jonathan A. Jenks, Robert W. Klaver, Kevin L. Monteith, Dwight H. Galster, Ron J. Schauer, Wilbert M. Morlock, Joshua A. Delger

Natural Resource Management Faculty Publications

White-tailed deer (Odocoileus virginianus) mortalities (n = 4,433) caused by collisions with automobiles during 2003 were modeled in 35 counties in eastern South Dakota. Seventeen independent variables and 5 independent variable interactions were evaluated to explain deer mortalities. A negative binomial regression model (Ln Y = 1.25 – 0.12 [percentage tree coverage] + 0.0002 [county area] + 5.39 [county hunter success rate] + 0.0023 [vehicle proxy 96–104 km/hr roads], model deviance = 33.43, χ2 = 27.53, df = 27) was chosen using a combination of a priori model selection and AICc. Management options include use of the model to predict …

Antibiotic-Mediated Inhibition Of Porcine Reproductive And Respiratory Syndrome Virus (Prrsv) Infection: A Novel Quinolone Function Which Potentiates The Antiviral Cytokine Response In Marc-145 Cells And Pig Macrophages, William A. Cafruny, Richard G. Duman, Raymond R. Rowland, Eric A. Nelson, Grace H. Wong

Veterinary and Biomedical Sciences Faculty Publications

Porcine reproductive and respiratory syndrome virus (PRRSV) is an economically significant agent for which there currently are no effective treatments. Development of antiviral agents for PRRSV as well as many other viruses has been limited by toxicity of known antiviral compounds. In contrast, antibiotics for non-virus microbial infections have been widely useful, in part because of their acceptable toxicity in animals. We report here the discovery that the quinolone containing compound Plasmocin™, as well as the quinolones nalidixic acid and ciprofl oxacin, have potent anti-PRRSV activity in vitro. PRRSV replication was inhibited by these antibiotics in both cultured MARC-145 cells …

Mycotoxins In Corn Distillers Grains A Concern In Ruminants?, A. Garcia, K. Kalscheur, A. Hippen, D. Schingoethe

SDSU Extension Extra Archives

The main fungi that produce toxins during storage belong to three genera: Aspergillus, Fusarium, and Penicillium. When dealing with cattle diets, it is not easy to correlate the presence of mycotoxins to that of molds. The same types of molds can produce different types of toxins, and different types of molds can produce the same mycotoxin. When addressing mycotoxicosis, the fact that multiple ingredients usually make up a dairy cattle diet can be viewed both positively and negatively. On the one hand, multiple feeds dilute the toxins from any given feed, resulting in a safer diet. On the other hand, …

Pvps And Qsas Opportunities To Addvalue To South Dakota Cattle, Russ Daly

SDSU Extension Extra Archives

The opening of the export market to Japan for cattle less than 20 months of age is a potential opportunity for South Dakota cattle raisers to add value to their calf crop. In order to qualify for this market, calves need to be age verified through programs already in place through the USDA. In most cases, when cattle are age verified through birth dates, they are also verified to a particular source (or farm), thus the term “age and source verified.” Cattle that have been age and source verified may bring a premium in certain markets, but premiums are subject …

Micotoxinas En Granos De Destilería Una Preocupación En Rumiantes?, A. Garcia, K. Kalscheur, A. Hippen, D. Schingoethe

SDSU Extension Extra Archives

Los principales hongos productores de toxinas durante el almacenaje corresponden a tres géneros: Aspergillus, Fusarium y Penicillium. No es fácil correlacionar la presencia de micotoxinas con la de los hongos en las dietas del ganado. Un mismo tipo de hongos puede producir el mismo tipo de toxinas y distinto tipo de hongos pueden producir la misma micotoxina. Al considerar las micotoxicosis, el hecho de que múltiples ingredientes formen por lo general parte de la dieta del ganado lechero puede verse tanto desde un punto de vista positivo como negativo. Por un lado, cuando se trabaja con varios alimentos se diluyen …

Formulating Mineral Supplements For Beef Cows, Cody Wright

SDSU Extension Extra Archives

Mineral nutrition of beef cattle is one component of ruminant nutrition that most producers address by simply purchasing a commercial supplement for their herd. However, this practice, while generally effective, can be wasteful. In many cases, commercial mineral supplements are formulated to provide in excess of 100% of the nutrient requirements for many different minerals. However, at least a portion of the minerals required by beef cows are provided by the feeds the cows are consuming. The formulation of supplements to supply only what the animal needs may provide an opportunity for cost savings. This paper will describe the process …

A Guide To The Common Native And Exotic Thistles Of South Dakota, Paul J. Johnson, Gary E. Larson, Darrell Deneke

SDSU Extension Special Series

This guide was compiled to provide an aid for the rapid identification of the more common pest and non-pest thistle species in South Dakota. Because of the great expense of managing and controlling invasive thistles in rangelands, pastures, and croplands, it is essential to be accurate in the identification of any species at hand. The recognition of native species not only helps maintain local biodiversity, but also prevents wasted effort, controls costs, and minimizes herbicide use and chemical pollution. It should be noted that native thistles are important both as floral resources for native pollinating insects and as seed sources …
