Stroke is the sudden onset of focal neurologic symptoms due to ischemia or hemorrhage in the brain. Current FDA-approved clinical treatment of acute ischemic stroke involves the use of the intravenous thrombolytic agent recombinant tissue plasminogen activator given >3 hours after symptom onset, following the exclusion of intracerebral hemorrhage by a noncontrast CT scan. Advanced MRI, CT, and other techniques may confirm the stroke diagnosis and subtype, demonstrate lesion location, identify vascular occlusion, and guide other management decisions but, within the first 3 hours after ictus, should not delay or be used to withhold recombinant tissue plasminogen activator therapy after …

Selenium In Birds, Harry M. Ohlendorf, Gary H. Heinz

United States Geological Survey: Staff Publications

Selenium (Se) is a metalloid trace element that birds and other wildlife need in small amounts for good health. The main purpose of this chapter is to interpret tissue concentrations of Se. However, because food is the main source of Se accumulation for birds and other wildlife, and because dietary concentrations for effects on bird reproduction have been reported, we also provide interpretive information on Se in the diet.

Se deficiencies in domestic poultry and livestock occur in some parts of the world and must be corrected by additions of Se to the diet. However, the range of dietary concentrations …

Heifer Development Systems: Dry-Lot Feeding Compared With Grazing Dormant Winter Forage, Richard N. Funston, D. M. Larson

West Central Research and Extension Center, North Platte

Two hundred ninety-nine Angusbased, nulliparous heifers (253 ± 2 kg initial BW) from 3 production years were utilized to compare traditional postweaning dry lot (DL) development with a more extensive winter grazing system utilizing a combination of corn residue and winter range (EXT). Heifers developed in the DL were offered a common diet after the weaning period for 208 d in yr 1, 194 d in yr 2, and 150 d in yr 3 until breeding. Heifers developed in EXT grazed corn residue for 135 d in yr 1, 106 d in yr 2, and 91 d in yr 3, …

Case Study: The Effects Of Maternal Nutrition On Steer Progeny Performance, A. F. Summers, K. H. Ramsay, Richard N. Funston

West Central Research and Extension Center, North Platte

Two locations on a commercial ranch in the Nebraska Sandhills were used to determine the effects of maternal nutrition on male progeny. Crossbred, spring-calving, multiparous cows were managed in a year-round grazing system. Cows at one location (yr 1 = 754; yr 2 = 700) received the equivalent of 0.95 kg/d (DM; 31.6% CP; HN) of supplement, and cows at the second location (yr 1 = 673; yr 2 = 766) received 0.37 kg/d (DM; LN) of the same supplement delivered 3 times weekly while grazing winter range from December through February. After weaning, a random group (yr 1 = …

Malaria Distribution, Prevalence, Drug Resistance And Control In Indonesia, Iqbal R.F. Elyazar, Simon I. Hay, J. Kevin Baird

United States Public Health Resources

Approximately 230 million people live in Indonesia. The country is also home to over 20 anopheline vectors of malaria which transmit all four of the species of Plasmodium that routinely infect humans. A complex mosaic of risk of infection across this 5000-km-long archipelago of thousands of islands and distinctive habitats seriously challenges efforts to control malaria. Social, economic and political dimensions contribute to these complexities. This chapter examines malaria and its control in Indonesia, from the earliest efforts by malariologists of the colonial Netherlands East Indies, through the Global Malaria Eradication Campaign of the 1950s, the tumult following the coup …

United States Public Health Resources

Background: The consumption of omega-3 (n–3) and omega-6 (n–6) essential fatty acids in Western diets is thought to have changed markedly during the 20th century.

Objective: We sought to quantify changes in the apparent consumption of essential fatty acids in the United States from 1909 to 1999.

Design:We calculated the estimated per capita consumption of food commodities and availability of essential fatty acids from 373 food commodities by using economic disappearance data for each year from 1909 to 1999. Nutrient compositions for 1909 were modeled by using current foods (1909-C) and foods produced by traditional early 20th century practices (1909-T). …

Prevalence And Predictors Of Food Insecurity In Migrant Farmworkers In Georgia, Brittany G. Hill, Ashley G. Moloney, Terry Mize, Tom Himelick, Jodie L. Guest

United States Public Health Resources

We examined the prevalence of food insecurity in migrant farmworkers in Georgia.Of these workers 62.83% did not have enough food, and non–H-2A workers had an adjusted risk of food insecurity almost 3 times higher than did H-2A workers. Lack of access to cooking facilities, transportation problems, and having children were additional risk factors. Migrant farmworkers are at extreme risk for food insecurity, although being an H-2A guestworker was protective within this population. Policy interventions are needed to protect these vulnerable farmworkers.

Long Term Depleted Uranium Exposure In Gulf War I Veterans Does Not Cause Elevated Numbers Of Micronuclei In Peripheral Blood Lymphocytes, M. V. Bakhmutskya, M. S. Oliver, M. A. Mcdiarmid, K. S. Squibb, J. D. Tucker

United States Public Health Resources

Depleted uranium (DU) is a high density heavy metal that has been used in military munitions since the 1991 Gulf War. DU is weakly radioactive and chemically toxic. Long term exposure can cause adverse health effects. This study assessed genotoxic effects in DU exposed Gulf War I veterans as a function of uranium (U) body burden. Levels of urine U were used to categorize the cohort into low and high exposure groups. Exposure to DU occurred during friendly fire incidents in 1991 involving DU munitions resulting in inhalation and ingestion exposure to small particles of DU and soft tissue DU …

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 …

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.

Cow Size

It is commonly …

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 …
