Rapid Determination Of Pork Sensory Quality Using Raman Spectroscopy, Qi Wang, Steven M. Lonergan, Chenxu Yu Jun 2010

Rapid Determination Of Pork Sensory Quality Using Raman Spectroscopy, Qi Wang, Steven M. Lonergan, Chenxu Yu

Agricultural and Biosystems Engineering Conference Proceedings and Presentations

Currently existing objective methods to evaluate tenderness and chewiness of pork in general do not yield satisfactory correlation to sensory panel evaluations, and their applications in meat industry are hence limited. In this study, a Raman spectrosensing method was developed to evaluate and predict tenderness and chewiness of pork loins. Raman spectroscopic binary barcodes for pork loins from 169 pigs were created based on their spectroscopic characteristics, and multivariate statistical discriminant model was developed based on the Raman barcodes to differentiate and classify pork loins into tenderness grades. Good agreement (> 82% correct predictions) with sensory panel results were obtained especially ...


Mycotoxin Contamination Of Corn: What It Is, What It Does To Pigs And What Can Be Done About It, John F. Patience, Steven M. Ensley, Sherry Hoyer Mar 2010

Mycotoxin Contamination Of Corn: What It Is, What It Does To Pigs And What Can Be Done About It, John F. Patience, Steven M. Ensley, Sherry Hoyer

Iowa Pork Industry Center Fact Sheets

Mycotoxins in corn are produced by certain molds which infect the ears of corn. Molds may be present without the production of mycotoxins, but mycotoxins cannot be produced in the absence of molds


Nonsolar Energy Use And One-Hundred-Year Global Warming Potential Of Iowa Swine Feedstuffs And Feeding Strategies, Peter J. Lammers, M. Douglas Kenealy, James B. Kliebenstein, Jay D. Harmon, Matthew J. Helmers, Mark S. Honeyman Mar 2010

Nonsolar Energy Use And One-Hundred-Year Global Warming Potential Of Iowa Swine Feedstuffs And Feeding Strategies, Peter J. Lammers, M. Douglas Kenealy, James B. Kliebenstein, Jay D. Harmon, Matthew J. Helmers, Mark S. Honeyman

Agricultural and Biosystems Engineering Publications

Demand for nonsolar energy and concern about the implications of fossil fuel combustion have encouraged examination of energy use associated with agriculture. The United States is a global leader in pig production, and the United States swine industry is centered in Iowa. Feed is the largest individual input in pig production, but the energy consumption of the Iowa swine feed production chain has yet to be critically examined. This analysis examines nonsolar energy use and resulting 100-yr global warming potential (GWP) associated with the swine feed production chain, beginning with cultivation of crops and concluding with diet formulation. The nonsolar ...


Incidence Of Bovine Enterovirus, Coronavirus, And Group A Rotavirus, And Concentration Of Total Coliforms In Midwestern Pasture Streams (Three-Year Progress Report), Douglas Allen Bear, James R. Russell, Yong.-Il. Cho, Steven M. Ensley, Kyoung-Jin Yoon Jan 2010

Iowa State Research Farm Progress Reports

Grazing management practices that allow cattle to congregate near pasture streams may result in the loss of vegetative cover, soil compaction, and accumulation of manure near the streams. These conditions may cause sediment, phosphorus, and pathogen loading of streams by direct deposition of feces or in precipitation runoff.


Cattle Temporal And Spatial Distribution In Midwestern Pastures Using Global Positioning (Three-Year Progress Report), Douglas A. Bear, James R. Russell, Daniel G. Morrical Jan 2010

Cattle Temporal And Spatial Distribution In Midwestern Pastures Using Global Positioning (Three-Year Progress Report), Douglas A. Bear, James R. Russell, Daniel G. Morrical

Iowa State Research Farm Progress Reports

Previous research has shown that grazing cattle tend to congregate in streamside zones of pastures to obtain water and shade for thermoregulation. However, problems associated with thermoregulation may be increased because of the presence of endophyte-infected tall fescue in pastures. Defining relationships between cattle distribution, such pasture characteristics as size, shape, shade distribution, botanical composition, and climatic factors related to heat stress, will provide the basis for the development and implementation of management practices that minimize nonpoint source pollution possibly associated with grazing cattle.

The growth of the ethanol industry in the Midwest has greatly increased in the last 5 years. This increase has affected the cattle industry in many ways. The increased demand for corn by this industry has driven prices to new highs over the last 3 years. This has affected feed costs for the cattle industry. On the other hand, the growth of the ethanol industry has increased the amount of byproducts that are produced.


Effects Of Stocking Rate, Botanical Composition, And Stream Bank Erosion On The Physical Characteristics Of The Streamside Zones Of Pastures (Three-Year Progress Report), Douglas Allen Bear, James R. Russell, Daniel G. Morrical, Mustafa Tufekcioglu, Thomas M. Isenhart, John L. Kovar Jan 2010
