The Role Of Industry Attributes In Determining The Pattern Of U.S.-Canada Intra-Industry Trade In 1997, Bashir Qasmi, Scott Fausti

Economics Staff Paper Series (1969 - 2017)

Trade flow patterns associated with U.S. - Canada bilateral trade by industry groups are investigated (Food and live animal products, manufacturing products, chemical products, and machinery and transportation products). The analysis uses the OECD data for 1997 U.S.-Canada bilateral trade flows combined with the U.S. industry characteristics data from the U.S. Economic Census. Levels of intra-industry trade, measured by the Grubel Lloyd Index, were regressed on a number of industry characteristics using OLS techniques. Empirical results indicate that selected measures of product differentiation, market power, and market structure are important influences upon U.S.-Canada bilateral trade in the selected industries. Finally, …

Observations From Cattle Mandatory Price Reporting, Matthew A. Diersen Mar 2004

Observations From Cattle Mandatory Price Reporting, Matthew A. Diersen

SDSU Extension Extra Archives

Under the Livestock Mandatory Reporting Act of 1999, large packers of cattle, swine, and sheep must report data from purchases and processing with respect to price, volume, and grade. The U.S. Department of Agriculture’s Agricultural Marketing Service (AMS) assembles and disseminates the price reports. Prices are now available for making annual observations and comparisons about industry trends. In addition, the recent high cattle prices and prospects of smaller supplies in the coming years make monitoring supply pertinent.

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 of …

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 outside …

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, CIDR were inserted …

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 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 previously weaned calves.
