Use Of Irrigated Pastures And Economics Of Establishment And Grazing, Jerry D. Volesky, Richard T. Clark

Range Beef Cow Symposium

The use of irrigated pasture is a potential option for many livestock producers. Irrigated cool-season species, for example, can be used as complementary forage to warm season rangeland (Nichols et al. 1993) or mitigate some of the effects of drought. Irrigated pasture can result in high animal production per acre; however, achieving the high production levels requires excellent grazing management with high water and fertilizer applications (Nichols and Clanton 1985; Gray et al. 2001). There are a number of management considerations associated with irrigated pasture. This includes practical details such as field selection, species and variety selection, seeding methods, and …

Strategically Feeding Protein And Energy During Wintering And Managing Cow Condition, Don C. Adams

Range Beef Cow Symposium

Concepts of managing cow body condition score (BCS) during the fall and winter are discussed. A key time in the year-long management of spring calving cows is late summer and fall. If cows are thin at the beginning of winter grazing, they are likely to be thin in the spring at calving. Fall weaning date and protein supplements in the fall and/or winter are key tools for managing cow BCS. Applications of weaning and supplementation in different extended grazing systems are presented. Strategic weaning and supplementation can have significant effects on economic net returns of the ranch.

Value And Use Of Corn Milling By-Products In The Cow Herdv, Richard J. Rasby, Galen E. Erickson, Terry J. Klopfenstein, Don C. Adams

Range Beef Cow Symposium

There are many different grain by-products available for cow/calf producers to use in rations. Grain by-products such as wheat mids, soy hulls, and cottonseed hulls have been available for many years and have been used effectively in cow diets and supplements. More recent grain by-products have come from the production of fructose (wet or dry corn gluten feed) or ethanol (wet or dry distillers grains). This paper will focus on by-product of corn milling industry. This paper will discuss the wet and dry milling process, product quality, nutrient quality, and research on use by beef cattle.

Effects Of Water Quality On Beef Cattle, Trey Patterson, Pat Johnson

Range Beef Cow Symposium

Producers often invest a great deal of time and money in developing nutrition and grazing strategies for their cattle. It is often taken for granted that if water is available, cattle productivity can be maintained. This is not always the case. The quality of water available to cattle can have substantial impacts on productivity. Much of the water available to cattle in South Dakota, and other parts of the United States, is not sufficient in quality to sustain performance and health of cattle.

Field observations from our laboratory since 1999 have shown both surface and subsurface water to be high …

Making Sense Of Mineral Supplementation, Cody L. Wright

Range Beef Cow Symposium

Mineral nutrition is one of the most complicated and least understood components of nutrition. For years, producers and researchers alike have known about the need for mineral supplementation; however, development of mineral supplements to meet the requirements of grazing cattle often becomes a difficult and challenging problem due to 1) changes in animal requirements with stage and level of production, 2) difference in forage supply of minerals, and 3) methods to supply cost-effective supplemental minerals that ensure adequate intake and bioavailability (Greene, 1999).

Macro Influences On The Beef Business, Wayne D. Purcell

Range Beef Cow Symposium

There are many major economic focuses at work in the sector. In late 2003, a start to the herd building phase of the cattle cycle is imminent. Export markets are coming back after faltering during 2002, and beef demand, domestic and international, is growing again. We have not seen the combination of heifer holdback to build the herd, which will reduce per capita beef supplies, and increased demand for beef since the early 1970’s. Unless corn prices surge, and this is unlikely, calf prices will go above $1.00 and generally stay there for the next several years—perhaps as long as …

Developing Replacement Heifers: Recent Research Findings On Target Weights And Fat Supplementation, Richard N. Funston, Gene H. Deutscher

Range Beef Cow Symposium

Proper development of replacement heifers is critical. Heifers should be managed to reach puberty early, conceive early in the first breeding season, calve unassisted, and breed back early for their second calf. This development needs to be accomplished at low costs without sacrificing performance. Previous studies (Patterson et al., 1992) indicate puberty can be expected to occur at a genetically predetermined size among individual animals; and only when heifers reach predetermined target weights can high pregnancy rates be obtained. Recommended guidelines generally have been 60 to 66% of mature weight in beef heifers, depending on frame size (Patterson et al., …

Supplementing Fat To The Cow Herd, Bret W. Hess

Range Beef Cow Symposium

Range livestock operations are continually challenged with the need to maintain sustainable production systems. Improvements in the herd’s biological efficiency are important considerations for the sustainability of beef cattle production. In a broad sense there are two levels at which improvements can be made, the cow and the calf. Considering that the majority of income for the typical cow-calf operation comes from the sale of the calf being produced, the calf would be a logical production unit to target for improvement. However, the key factor influencing total calf production is reproductive efficiency of the cow herd. Sound nutritional programs are …

Feeding And Managing Cows On High Grain Diets, Steve Paisley

Range Beef Cow Symposium

Increasing land prices, rising lease rates, restrictive grazing leases, intensified operations, as well as drought-related hay availability have all led to an increase in the use of alternative wintering programs for beef herds. While limit-fed grain rations have the potential to reduce wintering costs provided the programs are closely managed, additional herd management and feeding precision is needed to help ensure success. Several recent University studies have investigated different scenarios for limit-feeding high concentrate diets to heifers and adult cows. In addition, there have been several fact sheets, newsletters, and research reports discussing limit-fed high grain wintering rations for adult …

New Tools For Estrous Synchronization – Costs And Benefits, Doug D. Zalesky, Ryon S. Walker

Range Beef Cow Symposium

Estrous synchronization has become a powerful tool in managing breeding seasons to compliment niche markets. Synchronization of estrus, along with the use of AI, has become a popular technology that can introduce new sire genetics along with control of the breeding and calving season. Cattle producers have long searched for methods to efficiently and effectively synchronize females for artificial insemination without compromising conception or pregnancy rates versus conventional natural service breeding. Over the past 40 years, research scientists have developed and tested many synchronization protocols to synchronize estrus and ovulation in beef and dairy cattle with a goal to consistently …

Managing To Alleviate Calf Scours: The Sandhills Calving System, David R. Smith, Dale Grotelueschen, Tim Knott, Steve Ensley

Range Beef Cow Symposium

Diarrhea remains an important cause of illness and death of young beef calves. The economic effects of calf scours can be profound. Some beef cattle herds annually experience death rates of 5 to 10 percent or greater, sometimes with up to 100 percent of calves being ill. Economic costs to the disease include loss of performance, mortality, and the expense of medication and labor to treat sick calves. In addition, herd owners and their employees often become disheartened after investing long hours to treat scouring calves during an already exhausting calving season.

Management practices can have a profound effect on …

Early And Fence Line Weaning Of Calves: Producers’ Experience, Harlow W. Hill

Range Beef Cow Symposium

The reason I have been invited to speak today is because of our success with our early weaning program at Maddux Cattle Company for the last several years. I grew up in the western Sand Hills around Alliance, Nebraska. In the Sand Hills, the tradition was to wean in November. Once or twice I can remember us weaning early so we weaned in October. I left there 25 years ago and came to Maddux Cattle Company in southwestern Nebraska owned by Jack Maddux. I came on the job the 15th of September and the calves were already weaned. I shook …

The Two Best And Worst Decisions I Have Made In My Operation, Barry H. Dunn

Range Beef Cow Symposium

Since hindsight is always 20:20, important decisions made over a long career in the ranching business have gained a clarity that was surely missing while in the midst of making them. Or have they? With the destinations of the chosen paths clear, but the destinations of those paths not taken only a distant memory of what might have been, rationalization becomes a powerful force in evaluation. While ranch managers search for the perfect lenses to gain strategic advantages for the future, the lenses used to view the past are often clouded with blame, self-doubt, and perhaps, jealousy. And many times, …

Natural History Of The Mole Salamander Ambystoma Talpoideum In Virginia, Michael Scott Hayslett

Theses & Honors Papers

The Mole Salamander (Ambystoma talpoideum) has been known from Virginia for over two decades, but no intensive research on this state-rare species had been pursued prior to this project. Various aspects of mole salamander natural history were studied over a seven-year period throughout a seven-county area of central Virginia. New state distribution records for the species were recorded from Amherst, Appomattox, Buckingham, Campbell, Nelson, and Pittsylvania Counties. These records include a range of extension with the most northern occurrence known for this species in the United States.

Drift fence/pitfall trap studies were conducted on three ponds in two …

Multiwavelength Observations Revealing The Evolution Of The Outburst Of The Black Hole Xte J1118+480, S. Chaty, C. A. Haswell, J. Malzac, R. I. Hynes, C. R. Shrader, W. Cui

Faculty Publications

We report multiwavelength observations of the soft X-ray transient XTE J1118+480, which we observed with UKIRT, Hubble Space Telescope (HST), RXTE, Extreme Ultraviolet Explorer (EUVE) and many other instruments and facilities. Adding radio (Ryle Telescope, VLA), submillimetre (JCMT) and X-ray (Chandra and SAX) data from the literature, we assembled the most complete spectral energy distribution (SED) of this source yet published. We followed the evolution of this source for 1 yr, including six observations performed during the outburst, and one observation at the end of the outburst. Because of the unusually high galactic latitude of XTE J118+480, it suffers from …

A Close Look At U (5) ↔ Su (3) Transitional Patterns In The Interacting Boson Model, Feng Pan, J. P. Draayer, Yanan Luo

Faculty Publications

We study transitional patterns from the vibrational, U (5), to the rotational, SU (3), limit of the interacting boson model with a schematic Hamiltonian. The transitional behavior of low-lying energy levels, isomer shifts, E2 transition rates, and some other related quantities across the entire U (5) ↔ SU (3) transitional region are studied in detail. The analysis shows that nuclei in the critical region are soft. © 2003 Published by Elsevier B.V.
