The aim of this study is to evaluate the biosecurity level of 41 swine fattening herds located in Torino and Cuneo provinces and to survey some productivity parameters (mortality rate and chronic sick pigs rate). In order to collect data it has been used a questionnaire divided in different sections for a total of 42 items regarding internal and external biosecurity, feeding and sanitary treatments. For each item it has been evaluated the impact on the productivity parameters through 351 the comparison of the medians: graphic comparison of the data distribution (boxplot) and Kruskal-Wallis test. The mortality rate has been founded lower in case of use of exclusive equipment ( barnacles and ear brands.) (p<0.05); also in case the deaths store was insulated (p<0.05) and in case insect screen for windows have been installed (p<0.05). It is very important to underline the correlation trend between the increase of pig numbers for workers, the organization chart available and the mortality rate. These preliminary data will be completed with further parameters regarding welfare, using check list following the 91/630/CE law.

Abstract
The aim of this study is to evaluate the biosecurity level of 41 swine fattening herds located in Torino and Cuneo provinces and to survey some productivity parameters (mortality rate and chronic sick pigs rate). In order to collect data it has been used a questionnaire divided in different sections for a total of 42 items regarding internal and external biosecurity, feeding and sanitary treatments. For each item it has been evaluated the impact on the productivity parameters through 351 the comparison of the medians: graphic comparison of the data distribution (boxplot) and Kruskal-Wallis test. The mortality rate has been founded lower in case of use of exclusive equipment ( barnacles and ear brands.) (p<0.05); also in case the deaths store was insulated (p<0.05) and in case insect screen for windows have been installed (p<0.05). It is very important to underline the correlation trend between the increase of pig numbers for workers, the organization chart available and the mortality rate. These preliminary data will be completed with further parameters regarding welfare, using check list following the 91/630/CE law.
