Ocular infrared thermography to predict pork quality

Publication : lundi 17 mars 2014 18:33
Écrit par Weschenfelder A.V., Saucier L., Maldague X., Rocha L.M., Schaefer A.L., Faucitano L.

Infra-red thermography (IRT) body temperature readings were taken in the ocular region of 258 pigs immediately before slaughter. Levels of lactate were measured in blood taken in the restrainer. Meat quality was assessed in the Longissimus dorsi (LD) and Semimembranosus (SM) muscles. Ocular IRT (IROT) temperature was positively correlated with blood lactate levels, with pH taken 1 hour post-mortem and drip loss in the LD muscle, and negatively with pH 1 hour post-mortem in the SM muscle. Potentially, IROT may be a useful tool to assess the physiological conditions of pigs at slaughter and predict the variation of important meat quality traits. However, the magnitude of the correlations is rather low, so a further development of image capture technique and further studies under more variable preslaughter conditions ensuring a larger pork quality variation are needed.

French Animal Production: Characteristics, stakes, prospects and key figures

Publication : mercredi 26 février 2014 09:39
Écrit par M.P. Ellies-Oury

The present text is about the two books recently published by Lavoisier Ed. dealing with French Animal Production. The first one is about characteristics, stakes and prospects whereas the second one is about key figures.
These two books offers students a comprehensive, science-based approach to managing livestock for food (meat, fish, shell, milk, cheese, dairy products, eggs) but also sport and recreation. This text examines management practices of livestock production, but also breeding stakes and prospects, providing students the context and foundation upon which they can determine their academic and career focus.
Written by researchers, teachers and professional that are specialists of their domains, these books are richly illustrated with figures, photos, and current data, and appears as good references and resources to teachers and students in animal production and animal sciences.

Farmed animals’ status and rights in France: developments, challenges and outlook

Publication : mardi 11 février 2014 15:29
Écrit par M. Lesage

The status and rights of animals have evolved radically in the West, and developments have gathered considerable momentum over the past few decades. One of the latest shifts involves production-animal welfare. There has been remarkable progress on this front, but several currents of thought want to take it even further. The underlying trend in society seems to be heading towards greater concern for animal welfare, but this question is still the subject of some debate. Thinking about the status and rights of animals invariably involves thinking about the relationship between humans and animals, and views on this issue in particular diverge and occasionally clash. Whatever the answer, this societal trend entails—in the case of animals used in the service of humankind, and livestock in particular—the need to reconcile a new status and new rights with the need to manage the services they render (their productive function) and therefore constantly putting animal and human interests into perspective.
