Small Grains: 2005 Variety Recommendations (2004 Crop Performance Results), Cooperative Extension Service, South Dakota State University

SDSU Extension Circulars

Variety selection is a fundamental element in a sound crop production program. This report contains variety recommendations, descriptions, and yield data for the spring-seeded small grains – hard red spring wheat, oat, and barley, along with the fall-seeded small grain –hard red winter wheat. Key factors in variety selection include yield, yield stability, maturity, straw strength, height, test weight, quality, and disease resistance. Yield is an important factor; however, a variety with good disease resistance, straw strength, and high grain quality may be more profitable in some cases than the highest yielding variety. Disease resistance information is based on reactions to ...

Comparison Of 'Organic' And 'Conventional' Grains And Soybean Prices In The Northern Great Plains And Upper Midwest: 1995 Through 2003, Nicholas Streff, Thomas L. Dobbs Jun 2004

Comparison Of 'Organic' And 'Conventional' Grains And Soybean Prices In The Northern Great Plains And Upper Midwest: 1995 Through 2003, Nicholas Streff, Thomas L. Dobbs

Economics Pamphlet Series

Price premiums for organic crops drew the attention of an increasing number of farmers throughout the 1990s. Premiums contributed to the expansion of U.S. farmland managed under organic farming systems during that time period. Expansion of organic farming systems continued at least through 2001. According to the U.S. Department of Agriculture (USDA) Economic Research Service's most recent data on organic farming systems, U.S. farmers and ranchers added almost one million acres of certified organic farmland between 1997 and 2001, an increase of 74 percent. Over that same time frame, certified organic cropland increased by 53 percent ...

Evaluating Consumer Acceptability Of Various Muscles From The Beef Chuck And Rib, A.C. Kukowski, R.J. Maddock, D.M. Wulf Feb 2004

Evaluating Consumer Acceptability Of Various Muscles From The Beef Chuck And Rib, A.C. Kukowski, R.J. Maddock, D.M. Wulf

Animal Science Faculty Publications

One hundred thirty-eight consumers evaluated steaks from the complexus (CX), infraspinatus (IF), serratus ventralis (SV), supraspinatus (SS), and triceps brachii (TB) from the wholesale beef chuck; the deep pectoral (DP) from the wholesale brisket; and the longissimus thoracis (LT) from the wholesale rib. The LT was used as a reference for comparison to the other muscles. Ten USDA Choice and ten USDA Select boneless boxed beef subprimals were used for each muscle. Subprimals were aged 14 d from box date, frozen, and cut into 2.5-cm-thick steaks. Consumers rated the IF highest (P < 0.05) for overall like, tenderness, juiciness, and flavor, and assigned it the highest (P < 0.05) price/0.45 kg. The TB also was rated higher (P < 0.05) than the LT for overall like, tenderness, juiciness, flavor, and price/0.45 kg. The SV and CX were rated as being similar (P < 0.05) to the LT for overall like, tenderness, juiciness, flavor, and price/0.45 kg. Consumers rated the SS lower (P < 0.05) than the LT for tenderness, juiciness, flavor, and price. The DP was rated as the toughest, driest, and blandest (P < 0.05), resulting in assignment of the lowest (P < 0.05) price/0.45 kg. Differences in palatability ratings due to quality grade were found for several muscles; USDA Choice SV and SS were rated higher (P < 0.05) for overall like, tenderness, and juiciness than USDA Select SV and SS. For the IF, USDA Choice was rated higher (P < 0.05) for tenderness and juiciness than USDA Select. The USDA Choice TB was rated higher (P < 0.05) for juiciness, and the USDA Choice DP was rated higher (P < 0.05) for overall like, than their USDA Select counterparts. Tenderness, juiciness, and flavor ratings were correlated with overall like ratings (r = 0.84, 0.77, and 0.76, respectively) and with price (r = 0.73, 0.70, and 0.68, respectively). These results indicate the IF, TB, SV, and CX were acceptable, whereas and the SS and DP were unacceptable as steaks.


Effects Of Naturalized Population Of Yellow-Flowered Alfalfa On Species Richness And Biomass Production Of Native Rangeland, Lan Xu, Arvid Boe, Patricia Johnson, Kevin Kephart Jan 2004

Effects Of Naturalized Population Of Yellow-Flowered Alfalfa On Species Richness And Biomass Production Of Native Rangeland, Lan Xu, Arvid Boe, Patricia Johnson, Kevin Kephart

South Dakota Beef Report, 2004

The occurrence of naturalized yellow-flowered alfalfa on private and adjacent public rangeland in northwestern South Dakota presents a dilemma. Its ability to reproduce naturally in native rangeland demonstrates its value for rehabilitating severely depleted rangelands and increasing forage production and quality, soil carbon and soil nitrogen levels. On the other hand, the spread of alfalfa into native rangeland potentially threatens native biological diversity and may result in changes in ecological processes and functions (e.g., alteration of pools and flows of energy and nutrients). A study was initiated on the Grand River National Grassland in 2003 to determine the effects ...

Effects Of Prairie Dogs And Cattle On Vegetation Disappearance On Prairie Dog Towns In Mixed-Grass Prairie, Matthew B. Stoltenberg, Patricia S. Johnson, Alexander J. Smart, Lax Xu

South Dakota Beef Report, 2004

Quantitative data is lacking on competition between prairie dogs and cattle for forage on mixed-grass prairie pastures. The objective of this study was to determine the disappearance of vegetation attributable to cattle and prairie dogs on pastures with prairie dog towns. During the summers of 2002 and 2003, biomass estimates were made periodically on three mixed-grass prairie pastures in south central South Dakota that had varying degrees of prairie dog town coverage (percent of pasture area). Two types of grazing exclosures were established. Cattle exclosures allowed grazing by prairie dogs only. Cattle/prairie dog exclosures excluded both herbivores. Permanent plots ...

Intramuscular Tenderness Variation Within Four Muscles Of The Beef Chuck, Gina A. Searls, Robert J. Maddock, Duane M. Wulf

South Dakota Beef Report, 2004

To evaluate the potential for steak production from beef chuck muscles, we evaluated intramuscular tenderness variation within four beef chuck muscles: infraspinatus (IF), supraspinatus (SS), triceps brachii (TB), and serratus ventralis (SV). The IF, SS, TB, and SV muscles were cut into 1-in-thick steaks perpendicular to the long axis of the muscle. An identification tag was placed on each steak consisting of a muscle identification number, steak number, and orientation of the steak. Steaks were vacuum-packaged and stored at -8° F until used. Steaks were thawed at 34° F and broiled on electric broilers to an internal temperature of 160 ...


Ability Of Cidrs Or Melengestrol Acetate To Initiate Estrous Cycles In Early Postpartum Beef Cows, G. A. Perry, T. W. Geary Jan 2004

Ability Of Cidrs Or Melengestrol Acetate To Initiate Estrous Cycles In Early Postpartum Beef Cows, G. A. Perry, T. W. Geary

South Dakota Beef Report, 2004

Postpartum anestrous interval in beef cows is a major factor contributing to reproductive failure during a defined breeding season. Our objectives were to determine the ability of a controlled internal drug-releasing device (CIDR), or melengestrol acetate (MGA) to induce ovulation and to eliminate short estrous cycles. Multiparous beef cows (n = 75) were equally assigned by age, days postpartum, body condition, and body weight to one of three treatments: CIDR, MGA, or control. All cows were fed carrier (2 lbs•cow-1•day-1) with MGA (0.25 mg/lb) or without MGA for 7 days (day -6 to 0). On day -6 ...

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 ...


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 Jan 2004

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 ...

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. Initial predicted carcass composition ...


Impact Of Castration Time And Method On Carcass And Palatability Traits In Steers, Kelly W. Bruns, Robbi H. Pritchard Jan 2004

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 ...

Effects Of Sulfates In Water On Performance Of Cow-Calf Pairs, Hubert H. Patterson, Patricia S. Johnson, Earl H. Ward, Roger N. Gates Jan 2004

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 ...


Effects Of Sulfates In Water On Performance Of Steers Grazing Rangeland, Patricia S. Johnson, Hubert H. Patterson, Ronald Haigh Jan 2004

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 ...


Effects Of Thiamin Supplementation On Performance And Health Of Growing Steers Consuming High Sulfate Water, Earl H. Ward, Hubert H. Patterson Jan 2004

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 ...

Composition And Nutritive Value Of Corn Co-Products From Dry Milling Ethanol Plants, Simone M. Holt, Robbi H. Pritchard Jan 2004

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 ...
