Ground transportation of pigs at early ages is typical in modern swine production because the young animals are often produced in one part of the country and finished in another. One challenge associated with this practice is the profit-stripping incidence of mortality and compromised animal welfare due to stress stemming from unfavorable transporting conditions. The objective of this study was to examine possible causative relationships of mortality rate of weaned and feeder pigs to ground transportation conditions. Records of weaned and feeder pig transportation for the period of April 2012 – January 2014 were provided by a U.S. swine ...


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 ...
