Current Status Of National Cattle Evaluation Programs For Carcass Traits, Larry Benyshek
Current Status Of National Cattle Evaluation Programs For Carcass Traits, Larry Benyshek
South Dakota Beef Seedstock Symposium, 1991
At present, diet conscious consumers are exerting considerable pressure on the beef industry. Consumers continually indicate they are concerned about, and in fact, will not tolerate fat associated with red meat products (Breidenstein, 1988). This has resulted in many retailers trimming various cuts of beef to 1/8 inch of subcutaneous fat and in some cases a complete trimming of fat. It is probably conservative to estimate the industry produces an excess of 500 million pounds of fat each year from those carcasses with a yield grade above two. This excess fat represents the nutritional energy in more than a million …
Real-Time Ultrasound To Predict Carcass Traits In Live Cattle, Gene Rouse
Real-Time Ultrasound To Predict Carcass Traits In Live Cattle, Gene Rouse
South Dakota Beef Seedstock Symposium, 1991
Ultrasound technology offers a low-cost alternative to expensive and time-consuming progeny testing of beef sires for carcass merit. Expected progeny differences (EPDs) for carcass traits such as fat cover, ribeye area, and marbling would provide a tremendous tool to the beef 'cattle industry for producing a high quality, uniform end product. With these EPDs, breeders and commercial bull buyers will be able to directionally change the end product through genetic improvement programs. The objective of this report is to relate the accuracy with which fat cover and ribeye area can be measured with ultrasound equipment when compared with carcass measurements …

Impacts Of Types On Feed And Market Requirements, Donald L. Boggs
South Dakota Beef Seedstock Symposium, 1991
So you want to make them bigger! Or, do you want to add some milk to your cow herd? Improvements in these and other traits offer opportunities to increase production through higher weaning weights. However, the increased outputs are accompanied by increased feed and management inputs. Available research indicates that the increased production may or may not outweigh the increased inputs. Mature cow size and level of milk production are typically the factors considered when changes in cattle type are discussed. Numerous research studies have been conducted to evaluate the effects of these factors on biological and economic efficiency. In …
Which Cows Are More Efficient, D. M. Marshall
Which Cows Are More Efficient, D. M. Marshall
South Dakota Beef Seedstock Symposium, 1991
On the surface, the topic of cow efficiency may seem to be primarily of importance to commercial cow-calf producers. The topic is also of importance to seedstock producers, because the primary purpose of the seedstock industry is to provide genetic resources for the commercial industry. It is critical that seedstock producers develop a good understanding of the challenges faced by commercial producers in order to provide the best possible services. Feed costs for the cow herd represent the single largest expense in producing retail beef. The proportion of total energy utilized in beef production that is required to support the …
The State Of Interbreed Epds, Jim Gibb
The State Of Interbreed Epds, Jim Gibb
South Dakota Beef Seedstock Symposium, 1991
During the past ten years, the use of Expected Progeny Differences (EPDs) by both seedstock producers and commercial cattlemen has increased markedly. EPDs have proven to be very valuable for discerning within breed sire differences, but are still of no value for comparing sires between breeds. Even though EPDs were never intended for across breed comparisons, many commercial cattlemen find this limitation to be very frustrating.
Beef Cattle National Genetic Evaluation Programs, Larry Benyshek
Beef Cattle National Genetic Evaluation Programs, Larry Benyshek
South Dakota Beef Seedstock Symposium, 1991
Selection alters the frequency of genes in a population (breed) affecting a particular characteristic. Population genetic change is difficult for breeders to understand because they deal with individuals when making selection decisions and in their merchandising programs. Nevertheless, breeds (populations) which practice intense selection for characteristics of economic importance to the cattle industry will change genetically and eventually be the successful populations because they will leave the most progeny in the next generation. The genetic improvement of a population (breed) cannot overlook the individual because the individual, if selected, is the vehicle containing the genes which are to be passed …
Calving Difficulty In Beef Cattle: Part I, Harlan D. Ritchie, Peter T. Anderson
Calving Difficulty In Beef Cattle: Part I, Harlan D. Ritchie, Peter T. Anderson
South Dakota Beef Seedstock Symposium, 1991
Calving difficulty (dystocia) can increase calf losses, cow mortality, and veterinary and labor costs, as well as delay return to estrus, and lower conception rates. In two studies at the U.S. Meat Animal Research Center (MARC), Clay Center, Nebraska, calf losses within 24 hours of birth averaged 4 percent for those born with little or no assistance compared to 16 percent for those requiring assistance. Calf mortality increased by a 0.35 percent per pound increase in birth weight. In a Hereford herd at the U.S. Livestock and Range Research Station. Miles City, Montana, 57 percent of all calf losses were …

Computations Associated With National Beef Cattle Evaluation Programs, Larry Benyshek
South Dakota Beef Seedstock Symposium, 1991
In 1971-72 the first U.S. National Sire Summary was published by a beef cattle breed association. At that time the idea of extending beef performance records into a national progeny testing program was indeed revolutionary. Until 1972, truly accurate comparisons of bulls could only be made within a herd-year-season contemporary group. The first and subsequent National Sire Summaries compared bulls across herds and/or generations.
Calving Difficulty In Beef Cattle: Part Ii, Harlan D. Ritchie, Peter T. Anderson
Calving Difficulty In Beef Cattle: Part Ii, Harlan D. Ritchie, Peter T. Anderson
South Dakota Beef Seedstock Symposium, 1991
Many cattlemen believe reducing dietary energy during late pregnancy will decrease fetal size resulting in improved calving ease, whereas increasing energy will increase fetal size leading to a higher incidence of dystocia. Generally speaking, research has shown that lowering the energy allowance will decrease birth weight but will not significantly reduce dystocia. At MARC, Hereford and Angus 2-year-old heifers were fed three levels of energy (10.8, 13.7 or 17 .0 lb TDN/head/day) for 90 days prior to calving. Increasing the level of dietary energy resulted in increased birth weight but not increased dystocia; in fact, the incidence of calving difficulty …

Farm Program Flexibility Options And Sustainable Agriculture, Thomas Dobbs, David L. Becker
Farm Program Flexibility Options And Sustainable Agriculture, Thomas Dobbs, David L. Becker
Economics Research Reports
The phrase planting f1exibility was influential in the formation of The Food, Agriculture, Conservation, and Trade Act of 1990 (the 1990 Farm Bill).Several planting flexibility proposals were introduced during the congressional debates leading up to the 1990 Farm Bl11. Each proposal differed in the amount of planting flexibility given to farmers and which acres to use in the calculation of farm program benefits. In this report, we will look at three of those proposals --the Normal Crop Acreage program, the Triple Base program, and the Integrated Farm Management Program Option. For purposes of our analyses, we have selected 10 case …

South Dakota Farm Real Estate Values And Rental Rates 1991, Larry Janssen, Burton Pflueger
Economics Research Reports
South Dakota's agricultural land values increased 6.7% in 1990, paced by increases in grazing land values. Average agricultural land values (as of February 1, 1991) vary from $539 per acre in the southeast region, to $225 per acre in the central region to $89 per acre in northwest South Dakota. These are key findings from the SDSU 1991 South Dakota Farm Real Estate Market Survey reports. In each region, per acre values are highest for irrigated land, followed in descending order by non-irrigated cropland, hayland, tame pasture, and native rangeland. For each land use per acre land values are highest …

Projected Production Costs For Eastern South Dakota Crops: 1980-1990, Richard C. Shane
Projected Production Costs For Eastern South Dakota Crops: 1980-1990, Richard C. Shane
Agricultural Experiment Station Agricultural Economics Pamphlets (1941-1991)
The crop producer in South Dakota faces risk and uncertainty from many directions. Commodity prices and input costs are volatile, weather conditions change continuously and macroeconomic forces acting on inflation and interest rates leave the farmer "not knowing which way to turn." This high risk is accentuated by high investment requirements for land and machinery and high cash flow obligations. Annual or short-run decisions of what crop(s) and how much of each crop to plant are imperfect because of risk factors. Long-run decisions concerning equipment investment and land expansion are even more risky because of the longer planning horizon of …
Rural Economy Implications Of Farms Converting To Sustainable Agriculture Practices: Some Estimates For South Dakota, Thomas Dobbs, John D. Cole
Rural Economy Implications Of Farms Converting To Sustainable Agriculture Practices: Some Estimates For South Dakota, Thomas Dobbs, John D. Cole
Economics Research Reports
The purpose of the research reported in this monograph is to examine the hypothesis implied in that argument, i.e., that adoption of sustainable farming systems would adversely affect rural economies. Effects examined can be conceptualized in terms of the "backward" and "forward" linkages shown in Figure 1. The direct (or primary) effect of a conversion from conventional to sustainable farming systems in a local area is the effect on net incomes of agricultural households. Agricultural households are defined here as farm proprietors and their families and hired laborers. Secondary effects result from "backward" and "forward" linkages to the farm sector.

Western Wheatgrass Recovery From Drought, F. R. Gartner, E. M. White, K. D. Klement
Western Wheatgrass Recovery From Drought, F. R. Gartner, E. M. White, K. D. Klement
South Dakota Beef Report, 1991
Native grasses are predictably taller in wet years than in dry years and their density also increases with favorable precipitation. These responses of western wheatgrass are more dramatic on mechanically treated rangeland when precipitation is adequate. Measurements taken in July 1991 confirmed that western wheatgrass was slightly taller and density at least two times greater on mechanically treated claypan soils compared with untreated soils 13 and 18 years following treatment. Increases of this magnitude constitute a potentially greater carrying capacity which livestock producers should be prepared to utilize. This report briefly summarizes the effects of mechanical treatment on height and …
