• Assessment of the biological performance of individual animal/experimental groups.
• Survey of the natural behavior of the individual animal/experimental groups (is boar fattening possible without problems - good nature of the boars?!).
• Evaluation of slaughter performance with special consideration of the parameter - meat quality in general (pH value, drip juice, meat color, etc.).
• Determining the suitability of boar fattening as a suitable method for producing pork for consumption.
• Gathering information for practicing farmers on the fattening of boars.
• Determining the suitability of boar fattening as an alternative fattening method - no need to perform surgical castration of male piglets.

The following points are crucial:

• Increased profitability through the fattening of boars - young boars grow faster: Fattening adapted to the boars (especially in terms of feed) significantly influences the economic results of the fattening farmers.
• Results from studies in neighboring countries show that raising boars enables higher biological performance (e.g., feed conversion, daily weight gain). This can improve the economic situation of pig fattening farms.
• Meat quality – same or better quality in boar meat: Results from Switzerland, in particular, attest to the good to very good quality of young boar meat. Therefore, it is necessary to investigate whether castration is required. If the same or even better meat quality can be achieved with boars, then castration without pain relief is not necessary.
• Development of a suitable testing method to prevent boar taint in meat products: To establish boar fattening on a broad and accepted basis, it is necessary to develop an objective testing method that can demonstrably determine the quality of the carcass. This applies particularly to the boar-typical meat odor. This odor is caused by skatole and androstenone. These metabolic products accumulate primarily in the animals' fatty tissue and lead to the typical pig or boar odor during preparation.
• The use of the electronic nose or olfactometry is a suitable and objective measure.
• The only solution from an animal welfare perspective is to fatten boars, thus eliminating the need for the bloody castration of piglets. This would improve the acceptance of pig farming from both consumer and animal welfare perspectives. The extremely painful procedure of castration would be avoided, preventing unnecessary suffering for the animals.
