Impact of Selected Climate Parameters on the Foot Pad Health Status of Turkey Poults
it is commonly known,that the climate of the environment of productive livestock influences its well-being and productivity.Therefore the Order on the Protection of Animals and the Keeping of Production Animals(German designation: Tierschutz-Nutztierhaltungsverordnung,TierSchNutztV)claims in the General Requirements for Animal Husbandry Systems (§3 (3)2.),that barns must be sufficiently thermally insulated and equipped in such a way,that circulation,dust level,temperature,humidity and gaseous concentrations in the air must be kept in a range that is unharmful for animals (translated from German ).In a previous field study carried out from 2007 to 2009,11.860 turkeys were examined,amongst other parameters,concerning foot pad alterations.It then became evident that epithelial necrosis was diagnosed in 45% of the fattening turkeys at the early age of six weeks.Multiple factors have been linked to cause foot pad dermatitis.Aim of the present field study was to investigate possible connections between climate parameters and the occurrence of foot pad alterations during the early rearing phase.Altogether 2.681 beak-trimmed British United Turkeys 6 poults from twelve commercial farms were examined twice to that effect during generally two rearing periods.In addition to continuously recorded air temperature and humidity,ammonia and dust concentration were registered on each day of the examination.Dependencies on the foot pad health status could be detected concerning starting temperature (P<0.001),temperature measured one week before the second examination (P=0.004 ),humidity and gaseous ammonia concentration (P<0.001).The results show that climate parameters,which can also be easily assessed by the farm manager,can give valid information about frequency and severity of foot pad alterations in turkey poults during the early rearing phase.
