Farmers’ Adoption And Perceived Benefits Of Diversified Crop Rotations In The Margins Of U.S. Corn Belt, Tong Wang, Jin Hailong, Yubing Fan, Oladipo Obembe, Dapeng Li

Monoculture and simplified two-crop rotation systems compromise the ecosystem services essential to crop production, diminish agricultural productivity, and cause detrimental effects on the environment. In contrast to the simplified two-crop rotation, diversified crop rotation (DCR) refers to rotation systems that contain three or more crops. Despite multiple benefits generated by DCR, its usage has dwindled over the past several decades. This paper examined determinants of farmers' adoption decisions and perceived benefits of DCR in the west margins of the U.S. Corn Belt where crop diversity has declined. We analyzed 708 farmer responses from a farmer survey conducted in the eastern …
Grazing Behavior, Forage Quality, And Intake Rates Of Livestock Grazing Pastures Occupied By Prairie Dogs, Jameson R. Brennan, Ken Olson, Patricia Johnson, Janna Block, Chris Schauer
Grazing Behavior, Forage Quality, And Intake Rates Of Livestock Grazing Pastures Occupied By Prairie Dogs, Jameson R. Brennan, Ken Olson, Patricia Johnson, Janna Block, Chris Schauer
SDSU Beef Day 2020 Summary Publication
Prairie dogs can reduce the carrying capacity on rangelands by up to 50% through direct consumption of vegetation and by clipping plants to improve predator detection. Studies have shown that forage quality and digestibility are greater on prairie dog towns than off-town, however research is lacking that quantifies rates of forage and nutrition intake by cattle grazing pastures occupied by prairie dogs. The objectives of this study were to 1) evaluate relationships between on- and off-town plant communities and cattle grazing locations to identify trends in livestock grazing behavior throughout the growing season, 2) evaluate diet nutrient composition and intake …
Prairie Dogs And Livestock In Rangeland Systems: Balancing Biodiversity And Production In The Northern Mixed-Grass Prairie, Jameson Robert Brennan
Prairie Dogs And Livestock In Rangeland Systems: Balancing Biodiversity And Production In The Northern Mixed-Grass Prairie, Jameson Robert Brennan
Electronic Theses and Dissertations
A major constraint of beef production within the Standing Rock Reservation has been identified as a reduction in rangeland quality due in large part to wide-scale colonization by black-tailed prairie dogs (Cynomys ludovicianus). The desire exists within the community to design a holistic framework which incorporates livestock management with the goal of increasing production and rangeland health while still maintaining increased diversity associated with prairie dogs. Prairie dogs reduce the carrying capacity of cattle on rangelands by up to 50% on occupied hectares through direct consumption of vegetation and waste due to clipping to improve detection of predators. Livestock stocking …
Surveillance Of Emerging Livestock Viruses, Faten A. Okda
Surveillance Of Emerging Livestock Viruses, Faten A. Okda
Electronic Theses and Dissertations
Accurate and rapid diagnostic tests are essential for the management and control of emerging infectious diseases. Therefore, the overall goals of studies presented in this dissertation were to provide improved diagnostic and surveillance capabilities for several emerging viral diseases impacting the livestock industry and to provide insight into appropriate control strategies. Recent, severe outbreaks of porcine epidemic diarrhea virus (PEDV) in Asia and North America highlighted the need for well-validated diagnostic tests for identification of PEDV infected animals and evaluation of their immune status. PEDV was first detected in the U.S. in May 2013 and another swine coronavirus, porcine deltacoronavirus …

Comparison Of Estradiol-Trenbolone Acetate Implant Programs For Yearling Steers Of Two Genotypes, Robbi H. Pritchard
Comparison Of Estradiol-Trenbolone Acetate Implant Programs For Yearling Steers Of Two Genotypes, Robbi H. Pritchard
South Dakota Beef Report, 2008
Yearling steers (n = 400) were used to evaluate relative payout periods for implants when feeding high grain content diets. Implant treatments included (1) control (nonimplanted), (2) Synovex Plus, (3) revalor-s, and (4) Ralgro-revalor-s. The Synovex Plus (2), revalor-s (3) and Ralgro (4) were administered on day 1. The reimplant with revalor-s (4) was admnistered after 56 d on feed. Steers were managed in two groups. Initial BW and days fed were 782 lb, 131 d (Group I), and 661 lb, 145 d (Group II). Implants increased production rates and efficiencies, increased carcass size and reduced marbling when compared to …

Livestock Budgets And Whole-Farm Economic Analysis: South Dakota Sustainable Agriculture Case Farms, Donald Taylor, Clarence Mends, Thomas L. Dobbs
Economics Research Reports
In this report, livestock budgets for nine sustainable farmers in South Dakota who raise beef cattle and two of the same farmers who raise hogs are presented. Results of whole-farm economic analysis--in which the livestock, sustainable crop rotation, and non-sustainable rotation crop enterprise budgets on the respective farms are integrated with each other--are also presented. The final sections of the report cover results of analyses of (1) livestock price sensitivity and (2) on-farm manure production and disposition.

Crop And Livestock Enterprises, Risk Evaluation, And Management Strategies On South Dakota Sustainable Farms, Donald Taylor, Thomas L. Dobbs, David L. Becker, James D. Smolik
Economics Research Reports
This report presents findings from personal interviews undertaken in January-March 1989 with 22 of the 32 sustainable/regenerative farmers in South Dakota who responded to a Summer 1988 mail survey concerning their sustainable farming practices. [For the mail survey results, see Taylor, Dobbs, and Smolik, 1989.] The major purpose of the personal interview part of the study reported herein was to gain greater insight into (1) the sustainable crop rotations and livestock enterprises on these farmers' farms and (2) the judgments of these farmers about the riskiness and managerial strategies for meeting selected challenges of sustainable agriculture.
Price Variability At South Dakota Livestock Auction Markets, Larry Janssen, Richard Shane
Price Variability At South Dakota Livestock Auction Markets, Larry Janssen, Richard Shane
Economics Research Reports
Livestock prices are established through various market channels, such as terminal markets and auction markets. Auction sales account for 74% of all cattle purchases and 64% of all cattle sales by South Dakota producers (Clauson, 1983). Livestock auctions are also an important market channel for feeder pigs, slaughter hogs and slaughter lambs. The major purpose of this research was to determine which factors, controllable or noncontrollable, have a significant impact on livestock prices established at auction market outlets in South Dakota. Factors to be tested include market location, month of sale, sex, weight, breed and lot size. Data on sale …
Irrigation Development: It's Potential Impact On South Dakota's Economy, Richard Shane, Ralph J. Brown
Irrigation Development: It's Potential Impact On South Dakota's Economy, Richard Shane, Ralph J. Brown
Economics Research Reports
Irrigation development has been and will continue to be a key issue facing the people of the state of South Dakota. As irrigated acreage increases, benefits accrue throughout the State. The irrigator's income earning potential is expanded and income variability is reduced as drought impacts on yields are ameliorated. In addition, a more stable, larger quantity of feed can be produced for livestock production. This may allm-1 for expansion in the livestock industry or less importation of feedstuffs into an area. The nonfarm economy may also benefit from irrigation development. Since irrigation requires the purchase of more inputs such as …

The Runt Problem In Livestock, Paul P. Banker
SDSU Extension Circulars
Are runts a necessary evil or can they be largely, if not wholly, prevented? Several hundred practical stockmen were interviewed on this subject by the United States Department of Agriculture, and according to their opinions, based on experience, the runt problem can largely be prevented.
