Integrated evaluation of the sustainability of the Noir de Bigorre pork chain

Abstract : The social expectation for more sustainable livestock farming systems is growing. However, multidisciplinary approaches to assess the sustainability of pig farming systems are not sufficiently addressed. Twenty-five farms of local pig breed’s production in France (Noir de Bigorre chain – Gascon breed) were evaluated altogether in terms of environmental impacts (EN), economic sustainability (EC) and animal welfare (AW), using multiple factor analysis (MFA) and hierarchical clustering (HC). The first dimension of MFA (22.7% the total variance) was mainly associated to the EN (r=0.56) and AW (r=0.52), while the second (20.8% of the total variance) was linked to EC (r=0.41). The HC resulted in the identification of four groups: Group 1 comprised farrow-to-finish farms, with a farmer aged between 20-30 years-old, characterized by high EN, high dietary crude protein (CP) of fattening feeds and feed conversion ratio (FCR), low AW, and usually low EC. It could be described as ‘sustainability unfavourable’, with an overall inefficient management of the farm, when the high FCR could be a result of the high feed waste. Group 2, composed by 75% of feeder-to-finish farms, was characterized by high transferability, high land occupation (LO), and low AW. It could be described as ‘AW unfavourable and Transferability favourable’; maybe due to the high LO, animals were raised with lower level of care. Group 3 comprised farrow-to-finish farms managed by a man, and characterized by high EC, high number of sows and low EN per ha. It could be described as ‘EC and EN favourable’, described by high farm size and good management practices. Group 4, characterized by high AW and low EN, could be described as ‘AW and EN favourable’, with more attention to AW and lower surface available to pig production. The use of an integrated evaluation highlights different profiles of farmers which are associated with various results in the different themes considered. Based on complementary themes, it provides a broader representation of the sustainability of pig farming systems than the use of one theme.
