Abstract
BackgroundMale piglets are surgically castrated at a young age primarily to prevent pork meat from being tainted with boar taint, an offensive taste and odor that can be present in uncastrated male pigs. The practice of surgical castration is considered to be both stressful and painful for the piglets, and is therefore under scrutiny due to animal welfare concerns. Rearing of intact males or vaccination against boar taint (immunocastration) are two potential alternatives to surgical castration, but in order to successfully implement either of these alternatives, consumer acceptance of the different methods must be taken into consideration as it will be central for future sales of pork products. A consumer survey mapping Norwegian consumers’ attitudes toward piglet castration was conducted to explore whether the consumers’ position regarding castration has changed since an almost identical study was completed in 2008.ResultsThe internet-based survey found that Norwegian consumers are comfortable with the current practice of surgical castration with anesthesia, but also that they are open to the alternative method of vaccination against boar taint. When provided additional information stating that vaccination against boar taint may not be able to reduce boar taint to the levels that castration with anesthesia does, consumer skepticism towards vaccination increased. When evaluating castration methods, animal welfare was the most important influencing factor. Since the original survey from 2008, animal welfare was also the single factor that has increased the most among a set of assessment criteria when purchasing pork products.ConclusionNorwegian consumers regard animal welfare as an important factor both when purchasing pork products and when evaluating different methods of castration, and animal welfare as a factor has increased in importance since the initial survey in 2008. Although the current practice of castration using local anesthesia is still widely accepted among consumers, the acceptance of today’s method has declined since the original survey in 2008.
Highlights
Male piglets are surgically castrated at a young age primarily to prevent pork meat from being tainted with boar taint, an offensive taste and odor that can be present in uncastrated male pigs
To successfully implement either of the potential alternatives to surgical castration with anesthesia, consumer acceptance of the different methods must be taken into consideration as it will be central for future sales of pork products
Women placed more emphasis on animal welfare when buying pork than men (51% vs 35%), and animal welfare concerns when purchasing pork products were higher in respondents in the 60+ age bracket than for respondents in the lowest age bracket
Summary
Male piglets are surgically castrated at a young age primarily to prevent pork meat from being tainted with boar taint, an offensive taste and odor that can be present in uncastrated male pigs. In most European countries, male piglets are surgically castrated at a young age. This is primarily done to prevent pork meat from being tainted with an offensive taste. Requiring a licensed veterinarian to castrate piglets is likely easier to implement in a small-scale pork production system like that of Norway than it would be in most other European countries that operate on a much larger scale, as the veterinary cost would be too large for the pig producer
