In a first phase of research, data from 88 reproductive Italian pig breeding farms were analysed. In this investigation 4 main housing systems were identified: 1) collective pen for the entire pregnancy phase; 2) individual stall for the entire pregnancy phase; 3) individual stall for a first period of less than 35 days, followed by collective pen; 4) individual stall for a first period of more than 35 days, followed by collective pen. For each one of these solutions 10 representative farms were then selected and in these ones a more detailed investigation was carried on considering single animals. In order to evaluate the welfare conditions of the sows, a number of indicators of health, behaviour and reproductive performance were determined for a sample group of animals per farm, the number of animals being in proportion to the size of the farm. In particular the indicators regard: A) reproductive performances; B) physical integrity; C) behaviour; D) management (environmental conditions, type of feeding ratio during pregnancy and farrowing, fat thickness and body condition score); E) sanitary conditions; F) work times and costs of production. The research will continue for two farrowing cycles and is now half completed; as a result, only the intermediate results will be presented.

Abstract

In a first phase of research, data from 88 reproductive Italian pig breeding farms were analysed. In this investigation 4 main housing systems were identified: 1) collective pen for the entire pregnancy phase; 2) individual stall for the entire pregnancy phase; 3) individual stall for a first period of less than 35 days, followed by collective pen; 4) individual stall for a first period of more than 35 days, followed by collective pen. For each one of these solutions 10 representative farms were then selected and in these ones a more detailed investigation was carried on considering single animals. In order to evaluate the welfare conditions of the sows, a number of indicators of health, behaviour and reproductive performance were determined for a sample group of animals per farm, the number of animals being in proportion to the size of the farm. In particular the indicators regard: A) reproductive performances; B) physical integrity; C) behaviour; D) management (environmental conditions, type of feeding ratio during pregnancy and farrowing, fat thickness and body condition score); E) sanitary conditions; F) work times and costs of production. The research will continue for two farrowing cycles and is now half completed; as a result, only the intermediate results will be presented.
