Leg Surface Temperature Shows Leg Health in Poultry


Lameness costs the poultry industry in the USA 80 million birds at market weight. There is no information on impacts of lameness and other leg health issue on mortality and performance in the USA. The European Union Directive 2007/43/EC concluded that leg issues in broiler chickens are a major problem. In a 2017 report to the EU, Broom stated that leg problems in broiler chickens is the "greatest animal welfare problem in the World". (Broom, D.M.2017. Animal welfare in the European Union. Study commissioned by Policy Department  for Citizens' Rights and Constitutional Affairs, European Union.)

Infra-Red Thermography (IRT) allows determination of skin temperature. The approach is employed in airports (passport control) in some countries so that people with fevers are not admitted. With the exception of one study measuring foot surface temperature and its link to foot dermatitis, there have been no reports of the use of IRT in poultry.  This present invention is a novel approach to assess poultry leg health together with litter quality. It will be an important tool for integrators, growers and auditors in assessing the leg health in poultry.
