Unlike with conventional pig breeds, knowledge on growth and performance, and even more so on nutritional requirements, is very limited for local breeds. Using a modelling approach based on a growth model and data from literature or experiments from H2020 European Union project TREASURE, we determined the growth characteristics and nutritional requirements of nine local breeds (Alentejana, Basque, Bísara, Apulo Calabrese, Cinta Senese, Iberian, Krškopolje pig, Mangalitsa, and Moravka). Our results confirmed the lower growth potential of local pig breeds compared to conventional pig breeds. Moreover, a larger proportion of ingested and retained energy is dedicated to lipid deposition in local pig breeds, explaining the higher fat composition of the carcasses of these breeds. Our study provided initial insights into the nutritional requirements (such as amino-acids) of local pig breeds, providing a first step towards defining feeding strategies better adapted to the characteristics of these breeds.
