Factors Limiting Overwinter Survival Of Young-Of-The-Year Largemouth Bass In South Dakota, Todd D. Kolander

Electronic Theses and Dissertations

Studies were conducted to examine the effects of total length (TL), prey abundance, and water temperature on approximate body composition, condition index, and overwinter survival of young-of-the-year (YOY) largemouth bass Micropterus salmoides in South Dakota. Growth and condition of YOY largemouth bass stocks from South Dakota and Wisconsin were also compared. Study areas included two South Dakota University impoundments (0.8 hectare each), a gravel pit (7. 3 hectare), and laboratory aquaria. Hatchery reared YOY largemouth bass were graded into short (19-45 mm TL) and long (58-135 mm TL) length groups. Overwinter mortality was 78% and 85% in the two impoundments, …

Population Status And Characteristics Of Macrhybopsis Gelida, Platygobio Gracilis And Rhinichthys Cataractae In The Missouri River Basin, Selena J. Werdon

Electronic Theses and Dissertations

Few sturgeon chub (Macrhybopsis gelida: Cyprinidae) have been collected in the last decade, therefore their status, habitat selection and morphology were investigated at 172 previous collection sites. Data on two ecologically similar species, Platygobio gracilis and Rhinichthys cataractae, were also collected. Macrhvbopsis gelida were collected at 28 sites on the Powder River (n = 158) in Wyoming and Montana, and at one site on the Yellowstone River (n = 1) in Montana. Age-I, Age-II and Age-III M. gelida were collected. Specimens were 37 to 95 mm in total length. Macrhvbopsis gelida were ripe in mid-June, at water temperatures of 18.3-22. …

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 …

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.

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

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 …

Planetor: Review And Application, John Cole, Burton Pflueger

Economics Staff Paper Series (1969 - 2017)

Farmers are becoming increasingly aware of the environmental consequences of farming practices that have become "conventional" over the last 30 to 40 years. As agricultural producers, they are expressing concern about erosion, ground water contamination, and personal health considerations from chemical use. At the same time, farmers are concerned about the economic viability of their operations. Farmers cannot afford to sacrifice net farm incomes in order to meet stricter environmental regulations. A new software package named Planetor has been developed that can be used to examine the interrelationship between economic sustainability and environmental safety. Researchers working on the Big Sioux …

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 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 …

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 …

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 …

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 …

Alachlor Movement Through Intact Soil Columns Taken From Two Tillage Systems, Sharon A. Clay, William C. Koskinen, Paul Carlson

Agronomy, Horticulture and Plant Science Faculty Publications

Intact soil columns were evaluated as a screening technique to determine the effect of tillage on herbicide movement through soil. Alachlor was applied at 3.3 kg ai ha-1 to intact surface 0- to 10-cm and subsurface 10- to 20-cm soil columns (15-cm diam) taken from long-term no-till and conventional tillage plots and leached with 11.6 pore volumes (7 L; 39 cm) of water at a rate that did not create ponding. Leachate was collected in 0.07 pore volume fractions. Twice as much alachlor leached from surface no-till than from surface conventional tillage columns. The differences in leaching patterns from the …

South Dakota Farm Real Estate Values And Rental Rates 1991, Larry Janssen, Burton Pflueger

Economics Research Reports (1969 - 2017)

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 …
