| This research project examined the use of fiber-rich, non-food competing protein alternatives in pig fattening. The aim was to optimize protein supply by allowing pigs to self-regulate their feed intake. The effects of three feed groups (control, sustainable protein alternative, and choice group) on growth performance, slaughter parameters, and gastrointestinal physiology were analyzed.
Results showed that the choice group achieved a higher daily gain and improved feed efficiency (FE only in finisher phase) compared to the other groups, due to the apparently optimized nutrient intake. Female pigs demonstrated better feed efficiency, higher meat quality, and lower drip loss regardless of feed type. Increasing fiber content in diets also enhanced gut health, as indicated by microbiological and morphometric analyses.
The project highlights the importance of sustainable feeding strategies that reduce import dependency, decrease environmental impact, and promote animal health. These findings provide valuable insights for advancing efficient and practical pig feeding practices. |
