Pasture Weaning And Forage Barley To Extend The Grazing Season For Replacement Heifers, R. J. Pruitt, W. B. Epperson, V. N. Owens

South Dakota Beef Report, 2004

In a two-year study at the SDSU Cow/Calf Teaching and Research Unit, Brookings, SD, heifer calves were allotted to two weaning management treatments in early October at an average age of 202 days. The pasture-weaned group was separated from their dams and grazed grass pasture across the fence from their dams for two weeks. Then, until early December, they grazed “Robust” barley (forage type) that had been no-till planted into oat stubble in early August. The drylot-weaned group was fed a traditional weaning diet of grass hay, corn, and protein supplement from weaning until early December. The effect of management …

Impact Of Relocation And Weaning Stress On The Feedlot Performance Of Steer Calves During The Receiving Period, Simone M. Holt, Robbi H. Pritchard, Timonthy A. Wittig

South Dakota Beef Report, 2004

The effect of ranch management on weaning and relocation stress was investigated using spring born steer calves from a single source. Steers on mature (≥ 4 yr of age) dams were weaned at shipment (NW) whiles steers on young (< 4 yr of age) dams had been weaned and on feed at the ranch for 1 mo prior to shipment (PW). At shipment tympanic temperature (TT) loggers, an indicator of body temperature, were placed in 13 steers from each management group at shipment. Steers were transported together to the SDSU Research Feedlot (365 mi). Body weight after 21 d in the feedlot (670 vs 673 lb) and DMI (14.7 vs 14.9 lb) were similar (P > 0.10) between PW and NW steers, respectively. Average daily gain (2.66 vs 3.17 lb) and feed efficiency (5.53 vs 4.74 lb) were higher (P < 0.05) in NW steers. NW steers recorded higher TT (1.2 ºF; P < 0.05) than PW steers duing loading and transportation from the ranch, indicating a greater initial stress associated with NW. During the first 4 d at the feedlot DMI was lower for NW steers (11.2 vs 6.1 lb) and was slightly below maintenance. There were no differences (P > 0.05) in TT associated with this period of negative energy balance. Results indicate that pre-transit weaning, as a part of feedlot transition, did not add sufficient stress to alter TT compared to previously weaned calves.

The Effect Of Stage Of Growth And Implant Exposure On Performance And Carcass Composition In Steers, Kelly W. Bruns, Robbi H. Pritchard

South Dakota Beef Report, 2004

Angus and Angus cross Limousin steers (n = 182; initial BW = 681 ± 61.2 lb) were used to evaluate the influence of an estradiol-trenbolone acetate implant (24mg/120mg) on production efficiency and carcass traits when administered at specific stages of growth. Treatments (TRT) were as follows: No Implant, control (NI), Early Implant, d 1, BW = 681 lb (EI); or Delayed Implant, d 57, BW = 845 lb (DI). Comparisons were also made between the NI and implanted treatments (I; EI + DI). Steers were procured at weaning and were backgrounded (47 d) prior to the initiation of the experiment. …

Impact Of Castration Time And Method On Carcass And Palatability Traits In Steers, Kelly W. Bruns, Robbi H. Pritchard

South Dakota Beef Report, 2004

Angus and Angus x Limousin steers from one ranch were used to evaluate the effect of castration time and method on production and carcass traits. At 2 mo of age, calves were randomly assigned to one of two treatments (TRT); surgical castration at 2 mo age (SC) or castrated at 9 mo age (828 lb) by banding (BAND). Calves assigned to SC received a Synovex-C implant at castration. All calves were weaned at 5 mo of age with no difference in weaning weight. Calves were blocked into heavy and light groups with a 45 Mcal NEG/lb diet fed for 91 …

Effects Of Sulfates In Water On Performance Of Cow-Calf Pairs, Hubert H. Patterson, Patricia S. Johnson, Earl H. Ward, Roger N. Gates

South Dakota Beef Report, 2004

Past data from our laboratory showed water sulfate levels of 3,000 ppm reduced performance and health of growing steers during the summer. This experiment, conducted at the South Dakota State University Cottonwood Research Station, evaluated the effects of high sulfate water on cow and calf performance, milk production, and cow reproduction. Ninety-six crossbred, lactating cows (ages 2-13; average calving date of May 1) and their calves were assigned, after stratifying by age, weight, and previous winter management, to one of six pastures (16 cows/pasture) from June 3 to August 26, 2003. Pastures were randomly assigned to one of two water …

Effects Of Sulfates In Water On Performance Of Steers Grazing Rangeland, Patricia S. Johnson, Hubert H. Patterson, Ronald Haigh

South Dakota Beef Report, 2004

Surface and subsurface water in South Dakota often contains high concentrations of total dissolved solids (TDS) and sulfates, which, in severe cases, can cause livestock deaths. Data from our laboratory have demonstrated that sulfate concentrations of 3,000 ppm in water consumed by steers in dry-lot decreased ADG, feed intake, and water consumption. Little information is available on the effects of water sulfate concentrations on grazing livestock. This study evaluated the effects of water quality and two vegetation communities on the performance of steers grazing rangeland. Eight native pastures at the SDSU Cottonwood Research Station were used. Four pastures were dominated …

Effects Of Thiamin Supplementation On Performance And Health Of Growing Steers Consuming High Sulfate Water, Earl H. Ward, Hubert H. Patterson

South Dakota Beef Report, 2004

Thiamin injections are often used to treat sulfate induced polioencephalomalacia (PEM) in beef cattle. It is unclear whether supplemental thiamin will reduce the incidence of PEM and improve performance in steers consuming water with elevated sulfate levels. This study was conducted to determine the effects of thiamin supplementation on performance and health of growing steers consuming water with high sulfate levels. Sixty-three steers (737 ± 2.97 lb) were stratified by weight and randomly allotted to one of nine pens. Pens were assigned to one of three treatments (3 pens/treatment) based on water sulfates and thiamin supplementation. Treatments were: 1) low …

Effects Of Supplying Water With Varying Levels Of Total Dissolved Solids And Sulfates To Steers During The Growing Period On Subsequent Finishing Performance, Kent E. Tjardes, Hubert H. Patterson, Cody L. Wright, Bradley D. Rops

South Dakota Beef Report, 2004

Previous results have shown that water with elevated total dissolved solids (TDS) and sulfates was detrimental to performance of growing steers. The objective of this study was to determine finishing performance of steers that had previously received different levels of water quality during the growing period. In yr 1, 78 steers (824 lb) were assigned to one of eight pens (2-4 pens/treatment) based on water supplied during the 84-d growing period. Water TDS and sulfates during growing were: 1) 1,020 and 400; 2) 4,840 and 3,090; and 3) 6,190 and 3,950 ppm of TDS and sulfates, respectively. In yr 2, …

Composition And Nutritive Value Of Corn Co-Products From Dry Milling Ethanol Plants, Simone M. Holt, Robbi H. Pritchard

South Dakota Beef Report, 2004

The South Dakota ethanol industry is rapidly expanding. As a direct result of this expansion it is expected that in excess of 500,000 tons of corn co-products will be available to livestock enterprises annually as a feed source. Processing methods are, in general terms, similar among dry milling ethanol plants. However, newer technology and small deviations of methods can alter the nutritive value of the co-products. Subsequently, diet formulations using general nutritive values may be inaccurate and cause production inefficiencies. The objective of this research project was to characterize the composition and nutritive value of corn co-products produced from several …

Contagious Vs. Environmental Mastitis, Alvaro Garcia

SDSU Extension Extra Archives

Mastitis is an inflammation of the udder caused by microorganisms that enter the gland through the teat canal. Once inside the gland, these organisms find ideal conditions in which to multiply and, in turn, to damage the lining of the milk ducts, cistern, and alveoli. As a result, the cow’s immune response is triggered, and white blood cells travel to the udder to fight the infection. This results in increased somatic cell counts. The organisms responsible for this infection can be broadly classified into two groups: contagious and environmental.

This fact sheet is one in a series intended to answer — with science-based land-grant university research — questions frequently asked by the public about issues and needs affecting agricultural growth, urban expansion, and rural community development in South Dakota. During 2002, the year with latest available USDA figures, livestock production in South Dakota represented 50.7% of total agricultural cash receipts, followed by 42.4% for crops and 6.9% for government payments. Dairy products, at $178,176,000, were fifth of all agricultural cash receipts and were a highly significant portion of the state’s economy. In light of possible dairy expansion in the …

Factors Influencing A Declining Pronghorn Population In Wind Cave National Park, South Dakota, Jaret D. Sievers

Electronic Theses and Dissertations

Pronghorn (Antilocapra americana) were reintroduced into Wind Cave National Park (WCNP) in 1914 and thus, have inhabited the park for almost a century. A decline in the population has raised concern for the continued existence of pronghorn inside the park. Historically, pronghorn numbers reached greater than 300 individuals but were estimated to be less than 50 individuals during this study. Knowledge of food habits, genetic structure, causes of mortality, survival rates, and information related to movements were important to developing an understanding of factors contributing to this decline. Past studies have described spatial relationships and breeding behavior of adults and …

Effects Of Fire On The Nutritional Ecology Of Selected Ungulates In The Southern Black Hills, South Dakota, Teresa J. Zimmerman

Electronic Theses and Dissertations

Research in the 1990s indicated that populations of white-tailed deer (Odocoileus virginianus) in the northern and central Black Hills had declined since the late 1970s likely due to habitat deterioration. In August 2000, the Jasper fire consumed nearly 35,000 ha of ponderosa pine (Pinus ponderosa) forest in the southern Black Hills. To ascertain the nutritional condition of white-tailed deer and mule deer (O. hemionus) and their response to fire, 5 adult white-tailed deer and 5 adult mule deer were collected in burned and unburned habitat, in February and August, 2002 and 2003. Collected deer were weighed and necropsied at a …

Influence Of Diets Formulated To Increase The Supply Of Ketones Or Ketone Precursors On The Carbohydrate Status And Performance Of Transition Dairy Cows, Jeffrey Michael Defrain

Electronic Theses and Dissertations

Research to date has focused on increasing the supply of glucose precursors in transition dairy cows to reduce ketosis. Ketones and ketone bodies represent energy sources for body tissues; therefore, conserving blood glucose for lactose synthesis in the mammary gland. This led to the hypothesis that transition cows might benefit from diets formulated to stimulate rumen epithelial ketogenesis or dietary ingredients supplying ketone precursors. A series of experiments were conducted to study the impact of diets formulated to increase the supply of ketones (via feeding lactose, glycerol, or an alphaamylase enzyme preparation) or ketone precursors (feeding Ca soaps of longchain …

Nutritional Composition Of Selected Traditional Native American Foods, Suzanne Parker Stluka, Mary Lynn Gengler

The Journal of Undergraduate Research

Food choices have changed among Native American populations. Healthy food choices are subject to lifestyles, cooking skills, nutrition knowledge and the availability of healthy foods. There is a paucity of nutritional information on traditional and cultural Native American foods. Sixteen traditional Dakota recipes were prepared by members of the Sisseton Wahpeton Oyate, Sisseton, South Dakota. These foods were pureed, lyophilized and analyzed for moisture, ash, fat, protein, carbohydrate and individual mineral content using officially accepted methods. The following mineral elements were analyzed: calcium, copper, iron, magnesium, manganese, phosphorus, potassium, sodium and zinc. Methods of the Association of Official Analytical Chemists …

Use Of The Case Study Method To Enhance The Educational Experience For Students, David W. Willis

Bush Project Anthology

I have always believed in teaching with practical examples. However, I typically have presented these examples to students in a passive manner (i.e., a traditional lecture format). Because I was not pleased with retention of what I considered important material, I searched for a means to improve retention through more active learning while retaining practical examples. Thus, I first learned about the National Center for Case Study Teaching in Science (http://ublib.buffalo.edu/libraries/projects/ cases/ case.html) and attended their annual meeting.

Segregating Transgenic Grains: Results Of A Survey Among Country Elevators In South Dakota, Bashir Qasmi, Clayton J. Wilhelm, Evert Van Der Sluis

Economics Research Reports (1969 - 2017)

In 2002, cash receipts from crop production in South Dakota totaled $1.76 billion, accounting for 38 % of all receipts of agricultural producers in the state (South Dakota Agricultural Statistics Service, 2003). The three most important crops grown in South Dakota are soybeans, corn, and wheat. In 2001, South Dakota ranked 8th in the production of corn and soybean and 9th in wheat production among the nation's crop producing states (South Dakota Agricultural Statistics Service, 2003). These three crops accounted for 86 % of all cash receipts from marketing crops in the state. Due to the state's reliance on grain …

Using South Dakota Grown Field Peas In Swine Diets, Bob Thaler, Hans Stein

SDSU Extension Extra Archives

Due to changes in crop rotations, field peas are now more commonly grown in central South Dakota. Depending on variety, they can either be sold for human consumption or fed directly to livestock. Beef producers can bale the entire plant and feed it as a forage to ruminants, and swine producers can use the seed as a protein and energy source.

Role Of Physical Activity On Bone Mineral Content In Young Children, Bonny L. Specker

Ethel Austin Martin Program Publications

Previous studies identifying factors that influence peak bone mass have typically focused on older children, although it has been suggested that environmental factors early in life also may be important in optimizing the genetic potential for bone gain1 . Physical activity and calcium intake are considered major environmental factors influencing bone mass accretion. Longitudinal studies beginning in childhood show that high activity early in life is associated with high adult bone density2,3. The long-term effect between bone mass accretion and early calcium intake is less clear, with most trials finding that the beneficial bone effect of high calcium intake does …
