United States Geological Survey, Northern Prairie Wildlife Research Center: Publications

Each summer Yellowstone Wolf Project staff visit den sites to monitor the success of wolf reproduction and pup rearing behavior. For the purposes of wolf monitoring, Yellowstone National Park (YNP) is divided into two study areas, the northern range and the interior, each distinguished by their ecological and physiographical differences. The 1,000 square kilometer northern range, characterized by lower elevations (1,500–2,200 m), serves as prime winter habitat for ungulates and supports a higher density of wolves than the interior (20–99 wolves/1,000 km² versus 2–11 wolves/1,000 km²). The interior of the park encompasses 7,991 square kilometers, is higher …

Effects Of Distillers Dried Grains With Solubles And Lactose On Growth Performance Of Nursery Pigs, Huyen Tran, Roman Moreno, Justin W. Bundy, Erin Hinkle, Thomas E. Burkey, Philip S. Miller

Nebraska Swine Reports

A 4-week feeding experiment was conducted to evaluate effects of distillers dried grains with solubles (DDGS) and lactose on growth performance of nursery pigs. Ninety-six pigs (age, 23 + 2 days; initial body weight, 14.15 + 0.11 lb) were randomly allotted into each of 16 pens by gender, ancestry, and weight (6 pigs/pen; 4 pens/treatment). In phase 1 (weeks 1 and 2), pigs were fed 1 of the 4 treatments: A) control (no DDGS and lactose), B) 15% DDGS, C) 20% lactose, D) 15% DDGS + 20% lactose. In phase 2 (weeks 3 and 4), all pigs were fed a …

Utilizing Dried Distillers Grains With Solubles And Phytase To Alleviate Phosphorus Costs In Finishing Swine, Justin W. Bundy, Philip S. Miller, Roman Moreno, Thomas E. Burkey, Erin Hinkle, Huyen Tran

Nebraska Swine Reports

A total of 24 barrows (86.7 lb) were used over a 12-week experiment to evaluate the effects of utilizing dried distillers grains with solubles (DDGS) and phytase as alternatives to inorganic phosphorus (P) sources. Pigs were assigned to 1 of 4 dietary treatments. Treatments consisted of a common corn and soybean-meal fortified diet (CSB), a diet similar to CSB with phytase added in place of dicalcium-phosphate, a corn and soybean-meal diet with 20% DDGS, and a diet with 20% DDGS and phytase added in place of dicalcium-phosphate. Treatment did not affect (P > 0.10) pig performance for any of the growth …

Feed Efficiency - How Should It Be Used For The Cow Herd?, Andrew J. Roberts, Rick Funston, Travis Mulliniks, Mark Petersen, Mike Macneil

Range Beef Cow Symposium

Improving cow herd efficiency is critical because approximately 70% of the feed inputs required to produce a slaughter animal are used for maintenance, the majority of which is utilized by the dam (Williams and Jenkins, 2006). To date, much of the efforts to improve efficiency in cattle have focused on different measures of feed efficiency (variations in amount of feed consumed and rate of weight gain) determined during the growing phase. While this approach provides pertinent information concerning efficiency during the growing phase, the relationship to cow efficiency remains to be determined. When considering the usefulness of feed efficiency as …

Importance Of Steak Origin To Restaurant Customers, Kimberly A. Varnold, Chris R. Calkins, B. Lynn Gordon, Wendy J. Umberger

Range Beef Cow Symposium

Introduction

Today, consumers are more informed about the origin of their food due to the desire to have confidence in the safety of their food. This need for information has lead to an increase in demand for even higher levels of safety and quality (Unnevehr, 2003). Currently, traceability and source-verification are considered indicators of beef quality and safety by consumers. Mennecke et al. (2007) found that consumers place a high precedence on any information that can relate to the origin and production of their food. Research also indicates there could be preference for U.S. beef, especially beef from the Midwest …

Global Beef Marketing Opportunities, Paul Clayton

Range Beef Cow Symposium

Introduction

Over the last several years US beef production has experienced significant growth in globalization. This globalization is sometimes hard to define but in general the US has seen US beef companies open businesses in foreign markets as well as foreign companies establish business in the US. The type of global beef businesses range from suppliers of beef genetics via semen and embryos to processors and distributors of finished high quality beef products. Likewise raw materials, feed and production technologies may be sourced all over the world. This paper will discuss several of the factors that describe this globalization. Fundamentally …

Weaned Calf Growing Options: How Do We Economically Produce A 1,000 Lb Steer For Feedlot Entry, Terry Klopfenstein

Range Beef Cow Symposium

The cattle industry thrived for 50 years on cheap corn. However, cheap corn appears to be “a thing of the past”. Because of the unique ability of the ruminant to use forages and fibrous byproducts, the cattle industry has an opportunity to adjust nutrition programs away from “cheap corn” to forages. I believe there are two important myths that need to be discussed. Myth 1 is that forage gains are cheaper than feedlot gains, therefore we should put as much weight as possible on cattle using forage. We produced 1020 lb steers off grass on September 15 at a backgrounding …

Marketing Something Old, Not New

Range Beef Cow Symposium

Every single time I have Dr. Nathan Bryan on the radio he inspires me to write about the work he is doing. Bryan is one of only a couple dozen dietary nitrate researchers in the world and yet the work they do may be the most important in relation to understanding aging and improved human health. The really frustrating part regarding this information is that a few squeaky wheels attempt to create a negative image about nitrates in some meat products when, globally, consumers are actually nitrate deficient.

Dr. Nathan Bryan is a biochemist and researcher in Houston at the …

Cow Side Of Producing A 1,000 Lb. Feeder, Cow Size And Expenses, Ken Olson, Justin Waggoner, John Jaeger

Range Beef Cow Symposium

Introduction

Do relationships exist between cow size, nutrient requirements, and production capability? We can assume that a bigger cow will require more nutrients. What are the characteristics of that relationship? Is it a direct response wherein a cow that is 10% bigger than another will require 10% more nutrients, or is there economy of scale, so to speak? Can we assume that a bigger cow will be more productive? Is it automatic that bigger size means faster growth so we can expect the calves of bigger cows to grow faster? We will explore these relationships.

50 Years Of Applying Reproductive Technology To Breeding Cattle, George E. Seidel, Jr.

Range Beef Cow Symposium

Prior to the mid 20th century, reproductive management of both beef and dairy cattle consisted primarily of purchasing a bull every 2 years from a neighbor thought to have a herd with above average genetics. That description is still embarrassingly close to the truth for the majority of beef cattle herds in North America. The one striking difference is that bulls being purchased currently are, in fact, usually above average genetically. One result is that the amount and quality of beef produced per cow or per unit input of feed, labor, etc. have increased dramatically, at least partly due to …

Making Safe, Affordable And Abundant Food A Global Reality, Jeff Simmons

Range Beef Cow Symposium

Introduction

A growing wave of food insecurity threatens more than 1 billion people around the world.1 Global food costs are growing to dangerous levels, reaching record highs in January 2011. And these prices are expected to persist, according to the United Nations Food and Agriculture Organization (FAO).

We are at a crossroads. In the past two years, the global economic recession has decreased consumer buying power and increased food insecurity. In the next two years, tight supplies and rising food prices may stretch an already extended system to the breaking point. No longer is the number of hungry people steadily …

Vaccination: What The Heck Am I Doing?, G. L. Stokka

Range Beef Cow Symposium

The use of vaccines and vaccination in general can be a very confusing topic. There are literally hundreds of different vaccines available for use by beef producers, with multiple antigens and differing levels of effectiveness and safety. Veterinarians serve a critical function in making proper recommendations based on individual herd objectives and assessment of risk of exposure and economic loss. However, there is a lack of objective peer reviewed literature to assist the practitioner and beef producer in this area. The purpose of this paper is to bring some sense of philosophy, science and logic to this topic. Management keys …

Planning Ahead To Save Aums And The Cow Herd In Times Of Forage Shortage, Jerry D. Volesky, Don C. Adams

Range Beef Cow Symposium

Introduction

Drought is a recurring phenomenon with potential to significantly impact the livestock industry. During the past 14 years, the majority of livestock producers in the Great Plains and western states have experienced some level of drought ranging from moderate to extreme or even exceptional. Many grazing experts recommend developing a ranch drought plan to reduce their drought risk (Nagler et al. 2007). Most of these plans are specifically customized to an individual operation and include both short-term and long-term strategies and objectives. Producers with a drought plan actively monitor resources; build ecological, financial, and social resilience into their operations; …

Nutrient Composition Of Spoiled And Non-Spoiled Wet Byproducts Mixed And Stored With Straw, Jennifer R. Yelden, Crystal D. Buckner, Kelsey M. Rolfe Rolfe, Dana I. Christensen, Terry Klopfenstein, Galen Erickson

Nebraska Beef Cattle Reports

Wet corn byproducts were mixed with straw and stored in 55 gallon barrels for 56 days to simulate bunker storage. The spoilage process caused a decrease in fat content and an increase in pH, NDF, ash, and CP. Covering with plastic or distillers solubles reduced the amount of spoilage and the change in nutrient composition.

Winter Grazing System And Supplementation Of Beef Cows During Late Gestation Influence Heifer Progeny, Richard N. Funston, Jeremy L. Martin, Adam F. Summers, Don Adams, Jacqueline Musgrave, T. L. Meyer, Daniel M. Larson

Nebraska Beef Cattle Reports

Effects of cow winter grazing system and supplementation on heifer progeny were evaluated. Cows grazed range (WR) or corn residue (CR) with (PS) or without (NS) supplement. Both PS and CR increased weaning weight. Heifersfrom WR-NS dams weighed less at breeding and pregnancy diagnosis than WR-PS. Heifers from PS dams were younger at puberty, and pregnancy rate tended to be greater. Heifers from CR-PS dams gained the least and were least efficient. First-calf production and rebreeding were similar. There appear to be fetal programming effects of dam winter grazing system and supplementation on heifer progeny.

Effects Of Feeding High Levels Of Wet Distillers Grains And Straw On Beef Quality, Siroj Pokharel, Chris Calkins, Amilton S. De Mello Jr., Lasika S. Senaratne, Jeremy B. Hinkle, Timothy P. Carr, Galen Erickson

Nebraska Beef Cattle Reports

Cattle (n = 336; 595 ± 20 lb) were fed one of seven diets (corn/5% straw; 40% distillers grain (DG)/5% straw; 70% DG/8% straw; 70% DG/25% straw; 77.5% DG/9% straw; 77.5% DG/17% straw, and 85% DG/10% straw – DM basis) to measure effects of feeding high levels of DG on shelf life of aged beef. Except for 70% DG/25% straw, strip loins were cut into three steaks each after 20 days of postmortem aging for 0, 4, and 7 days of retail display. The treatment having 70% DG/8% straw had the greatest oxidation status. Trans fatty acids and polyunsaturated fatty …

Influencing Steer Performance Through Maternal Nutrition, Adam F. Summers, Kenneth H. Ramsay, Jim Teichert Teichert, T. L. Meyer, Rick N. Funston

Nebraska Beef Cattle Reports

Cows were fed a 28% CP cube at one of two supplement levels, high (HN) or low (LN), while grazing dormant winter range during late gestation to determine the effects of maternal supplementation level on male progeny performance and carcass characteristics. Steer initial BW did not differ between treatments; however, year 1 steers from cows fed higher supplement levels had greater final BW, HCW, marbling scores, and carcass value compared with steers from cows receiving lower supplement levels. Year 2 HN steers had greater proportions grading USDA quality grade modest or greater when compared to steers from both treatments in …

Marketing Source-Verified Beef To Restaurant Patrons, Kimberly A. Varnold, Chris Calkins, B. Lynn Gordon Gordon, Wendy I. Umberger

Nebraska Beef Cattle Reports

To determine consumer ordering behaviors in high-end restaurants and to see if consumers are interested in the origin of their beef, both an online survey and in-restaurant taste testing were conducted. About two-thirds of the participants in the in-restaurant taste testing ordered the steak with either the state or farm-of-origin description. Compared to a non-source verified steak, taste participants were willing to pay $4.74 more for the steak with the state-of-origin description, and $8.75 more for the steak with the farm-of-origin description. Almost all of the participants acknowledged the best beef comes from the Midwest, specifically naming Nebraska as a …

Protein, Fiber, And Digestibility Of Selected Alternative Crops For Beef Cattle, Jennifer A. Walker, Karla H. Jenkins, Terry Klopfenstein Klopfenstein

Nebraska Beef Cattle Reports

Field peas, dry edible beans, pumpkins, chicory, beets, and beet pulp grown in western Nebraska were analyzed for their salvage value in beef cattle diets when they do not meet specifications for human consumption. The digestibilities of all the crops were high (61-88%). Beet pulp, beet root, and chicory root were low in CP (< 7%) while all other crops were greater than 9%. Neutral and acid detergent fiber were ≤ 50%. Lectins in raw dry edible beans force them to be limited to < 2% of diet DM. Palatability of chicory root can reduce intake.

Feedlot Cattle Performance When Fed Silage And Grain From Second-Generation Insect Protected Corn, Parental Line Or Reference Hybrids, Barry M. Weber, Brandon L. Nuttelman, William A. Griffin Griffin, Galen Erickson, Terry Klopfenstein

Nebraska Beef Cattle Reports

Feed conversion and carcass characteristics of cattle fed second generation insect-protected (Bt) corn and corn silage was compared to those fed a nontransgenic parental hybrid and two commercially available nontransgenic reference hybrids. Finishing performance and carcass characteristics were not influenced as a result of corn source.

Nebraska Beef Cattle Reports

Effects of feeding second generation insect-protected transgenic corn (MON 89034) on growing steer performance was evaluated in two experiments. In Experiment 1, a corn silage-based diet was fed to growing steers in pens, and the transgenic test hybrid was compared to a non-transgenic parental hybrid and two commercially available reference hybrids. In Experiment 2, steers grazing corn residue of the transgenic test hybrid were compared to steers grazing a non-transgenic parental hybrid. In both experiments, growing performance was not affected by source of corn silage or residue.

Nebraska Beef Cattle Reports

A low-fat (4.72%) wet distillers grain (LFWDG) diet was compared to a traditional wet distillers grain with solubles (WDGS) diet and a corn-based diet. All wet distillers diets increased polyunsaturated fatty acids in comparison to the control. The LFWDG diet caused greater oxidative rancidity and had a decreased shelf life; however, there was no change in sensory properties. The LFWDG diet evaluated in this study caused decreased oxidative stability of the muscle compared to the TWDGS and the control diets.

Heifer Development Systems: A Comparison Of Grazing Winter Range Or Corn Residue, D. M. Larson, Andrea S. Cupp, Richard N. Funston
