Monensin, Protein Supplementation and Tylosin for Feedlot Cattle

Scientific research has made substantial contributions to the efficiency of American agriculture. Livestock producers in particular have benefited from the extensive study of animal nutrition. Nutrient requirements of animals and the nutrient composition of feeds are essential to efficient and economical feeding of farm animals. Research over many years has provided considerable information on animal requirements and feed composition. While there are still many gaps of knowledge in those areas, available information allows wise choice in selecting feedstuffs and using them in various combinations to meet animal requirements for various productive purposes. Feed costs represent the single largest expenditure in a livestock feeding enterprise. Extensive research has therefore been devoted to investigation of method to improve the efficiency with which animals utilize feed. Awareness of food shortages in developing nations has placed additional importance on techniques which improve the feed efficiency of domestic livestock. Cattle feeders have benefited from the availability of growth stimulants and antibiotics which can improve growth rate and feed efficiency. Honensin is a feed additive which was made available to cattle feeders in 1975. While its action is distinct from antibiotics, the product has been shown to improve the efficiency of energy conversion in growing and finishing cattle. The effects of monensin on protein utilization are not well established. A primary objective of the feeding experiments reported was to determine the influence of monensin on the dietary protein needs of cattle fed corn silage growing rations and high-concentrate finishing rations. Of additional interest was the response to difference sources of supplemental protein, either soybean meal or urea, when fed with monensin in a growing ration. Another objective was to determine the usefulness of feeding an antibiotic, tylosin, in combination with monensin in a high-corn grain finishing ration

After Wildfire: Range Recovery

In the grip of drought, livestock producers often must deal with the additional impact of wildfire. While drought conditions develop gradually and can be anticipated, losses due to wildfire are sudden and devastating

Using the Balanced Scorecard for Ranch Planning and Management:Setting Strategy and Measuring Performance

The key to business success—whether operating a ranch or a Fortune 500 company—lies in management and planning. It’s the ability to have foresight, to carefully evaluate and choose appropriate new concepts and technologies, and to implement a well thought- out plan that complements all aspects of the business. The highly-respected former CEO and chairman of General Electric Jack Welch put it this way: Good business leaders create a vision, articulate the vision, passionately own the vision, and relentlessly drive it to completion. How does that description apply to you? Are you a visionary business leader for your ranch enterprise? Or can you become one? This manual introduces the “Balanced Scorecard” developed by Dr. Robert Kaplan of the Harvard Business School and Dr. David Norton. The duo authored the book The Balanced Scorecard: Translating Strategy Into Action, and the scorecard format has been used by thousands of global companies and small businesses since the early 1990s when it was initially developed. While this concept may be relatively new to the ranching community, adopters of this approach to management include corporate icons like General Electric, DuPont, Ford Motor Company, IBM, and Walt Disney World. Using the scorecard, a manager can clearly see the things that need to be measured to “balance” different competing parts of the ranch. For example, rather than analyze financial records alone—which are only capable of telling of past events—this approach also takes into account things such as customer relationships, ranch processes, and investment in family members and employees’ learning and growth— all of which can have an impact on future business success. Central to the effectiveness of the Balanced Scorecard is viewing the business (your ranch) from these perspectives and then developing strategies and evaluating outcomes relative to each of those perspectives. By doing so, you can build a stronger base for your future sustainability. To that end, this manual offers a step-by step guide for the ranching industry to adopt the Balanced Scorecard and move toward managing for ranch business success

Effects of Sulfates in Water on Performance of Cow-Calf Pairs

Past data from our laboratory showed water sulfate levels of 3,000 ppm reduced performance and health of growing steers during the summer. This experiment, conducted at the South Dakota State University Cottonwood Research Station, evaluated the effects of high sulfate water on cow and calf performance, milk production, and cow reproduction. Ninety-six crossbred, lactating cows (ages 2-13; average calving date of May 1) and their calves were assigned, after stratifying by age, weight, and previous winter management, to one of six pastures (16 cows/pasture) from June 3 to August 26, 2003. Pastures were randomly assigned to one of two water sulfate levels (three pastures/level). Treatments were low sulfate water (LS; average 388 ± 17 ppm sulfates) or high sulfate water (HS; average 2,608 ± 408 ppm sulfates). The HS water was created by adding sodium sulfate to the LS water. Cow 12-hour milk production was estimated by the weigh-suckle-weigh method at the initiation of the trial and again on July 2 and July 29. Initial milk production estimates were used to adjust the July 2 and July 29 estimates, which represented an average of 64 and 91 days into lactation, respectively. Cows on LS gained 15 lb and cows on HS lost 36 lb during the experiment (P = 0.04). Cows on HS tended to loose more (P = 0.10) body condition than LS (-0.27 and -0.48 for LS and HS, respectively). Twelve-hour milk production did not differ on July 2 (P = 0.33; 10.6 and 9.5 lb for LS and HS, respectively) or July 29 (P = 0.48; 11.9 and 11.0 lb for LS and HS, respectively). Calf ADG did not differ (P = 0.71) between treatments. Pregnancy rates (55-d breeding season) were 98% and 94% for the LS and HS treatments, respectively (P = 0.36). Sulfate levels averaging 2,608 ppm in the drinking water of cow-calf pairs during the summer increased cow weight loss and condition loss but did not reduce calf performance or reproduction compared to sulfate levels averaging 388 ppm

Distribution and Productivity of Naturalized Alfalfa in Mixed-Grass Prairie

Alfalfa (Medicago sativa L.) is an important forage and conservation crop in North America but occurrences of naturalized alfalfa in rangelands are rare. A naturalized population of yellow-flowered alfalfa in mixed-grass prairie on the Grand River National Grassland in South Dakota has potential agricultural value for the region. Despite this value, the distribution pattern of this alfalfa among and within native plant communities in the northern Great Plains is unknown. Field studies were conducted from 2003 through 2006 along topographic positions at two sites where yellow-flowered alfalfa was naturalized to evaluate the relationships of yellow-flowered alfalfa on biomass production, cover, species diversity, and alfalfa seedbank distribution characteristics. High yellow-flowered alfalfa cover (\u3e50%) was associated with increased total biomass and occurred exclusively in swales and toeslopes that had silty loam soils. However, species diversity and non-alfalfa biomass were reduced when yellow-flowered alfalfa cover was high. Yellow-flowered alfalfa cover was lower and species richness was higher on backslopes and shoulder areas where sandy loam soils were present. A strong positive linear association existed between yellow-flowered alfalfa cover and alfalfa seedbank density (r values ranged from 0.76 to 0.82, P \u3c 0.0001). Greater than 99% of the seeds were viable but germination rate was only 4%, indicating a high percentage of hard seed in this alfalfa population. Naturalized yellow-flowered alfalfa was a dominant component of a stable, low diversity plant community composed of mainly introduced species in rich soils of swales/toeslopes that contributed to forage production and quality in mixed-grass prairie in the northern Great Plains

Validation of a Technique for Estimating Alfalfa (Medicago sativa) Biomass from Canopy Volume

Determining biomass production of individual alfalfa (Medicago sativa L.) plants in space planted evaluation studies is generally not feasible. Clipping plants is time consuming, expensive, and often not possible if the plants are subjected to grazing. A regression function (Bʹ = 0.72558 + 0.11638 × Vʹ) was developed from spaced plants growing on rangeland in northwestern South Dakota near Buffalo to nondestructively estimate individual plant biomass (B) from canopy volume (V). However, external validation is necessary to effectively apply the model to other environments. In the summer of 2015, new data to validate the model were collected from spaced plants near Brookings, South Dakota. Canopy volume and clipped plant biomass were obtained from ten alfalfa populations varying in genetic background, growth habit, and growth stage. Fitted models for the model-building and validation data sets had similar estimated regression coefficients and attributes. Mean squared prediction errors (MSPR) were similar to or smaller than error mean square (MSE) of the model-building regression model, indicating reasonable predictive ability. Validation results indicated that the model reliably estimated biomass of plants in another environment. However, the technique should not be utilized where individual plants are not easily distinguished, such as alfalfa monocultures. Estimating biomass from canopy volume values that are extrapolations (\u3e2.077 × 106 cm3) of the model-building data set is not recommended

Range Management and Soil Seed Bank: New Perspective

Seed banks are considered essential constituents of plant communities and contribute significantly to ecological processes. Seed banks play a critical role in managing the composition and structure of existing vegetation, restoring native vegetation, creating habitat for animals, preserving genetic diversity, and recovering endangered plant species. Therefore, implementation of management practices based only on existing aboveground vegetation, without the information of soil seed flora is obviously incomplete and dangerous. Our objectives were to determine effects of prescribed burning and reseeding managements on soil seed bank composition and the relationship between the soil seed bank and aboveground vegetation. The study was conducted at the Oak Lake Field Station in eastern SD during 2005. Seven pairs of 100 m2 macroplots were established in the areas of native prairie and restored rangeland through prescribed burning and reseeding. One macroplot of each pair was randomly selected and burned in May with the other remaining unburned. Within each macroplot, ten 0.25 m2 quadrats were randomly established. Cover by species was estimated for aboveground vegetation in early June and August. Three soil cores were extracted using a bulb planter in the same quadrats where vegetation samples were collected for seed bank determination. Non-reseeded areas had fewer total seeds than reseeded areas. Non-reseeded areas lacked native graminoid seeds and were dominated by introduced graminoid seeds. Burning reduced the percent of introduced graminoids to the seed bank and enhanced native forbs. Burning may decrease competitive capability of introduced species and promote the existing native species stands through vegetative reproduction, but may not influence the seed bank like reseeding. Species compositions in the aboveground and seed bank were strikingly dissimilar

Public Price Reporting, Marketing Channel Selection, and Price Discovery: The Perspective of Cow/Calf Producers in the Dakotas

Cow/calf producers operating in the Dakotas were surveyed on their price discovery strategies, marketing channel preferences, and their perceptions of how regime change in the public price reporting system for fed cattle affected the beef industry in general and the cow/calf industry in particular. Survey results indicate cow/calf producers consider local institutions (auction barns, etc.) to be more reliable for price discovery than regional or national institutions (futures market, USDA public price reports, satellite auctions, etc.). The auction barn marketing channel is the preferred channel for marketing cattle and is considered the most reliable source of market information by producers. Dakota cow/calf producers perceive livestock mandatory price reporting as benefiting the beef industry in general, but consider public price reports to be less reliable than local sources of market information.beef supply chain, cow-calf marketing, marketing channel, price discovery, public price reporting, Livestock Production/Industries,

The Effect of Early vs. Normal Calf Weaning on Feedlot Performance and Herd Management: A Cross-Discipline Case Study

A study of early vs. normal weaning of calves concludes that early weaning improves feedlot production efficiency, reducing per day and per pound feedlot production costs. Early weaned steers finished higher thus feedlot profitability was not affected. Early weaning has a positive affect on cow health and pasture utilization rates.Livestock Production/Industries,
