Key Facts and Figures

Pig vaccination around the world

IMPROVAC, the vaccine against boar taint, was developed in Australia and is produced by Zoetis. The most extensive experience so far with the use of vaccination against boar taint is in Australia and New Zealand. Since 1998, vaccination has been used successfully in these two countries under the brand name IMPROVAC. Because of its history of proven performance, this vaccine has been licensed for use in many countries around the world.

Castration

Traditionally, castration of male piglets has been the preferred method of combating taint, with an estimated 95% of the world’s male pig population castrated.

Physical castration has a number of inherent drawbacks – all of which make it less than ideal from a commercial point of view.

The process itself is time consuming and labour-intensive for the farmer, and carries the risk of infection and hernia which at best will require treatment and set the pig back, and at worst will contribute to mortality.

While physical castration may control the cause of boar taint, castrated animals exhibit a less efficient feed conversion rate than a boar. The alternative, slaughtering male pigs before they mature sexually, also means that producers miss out on the rapid growth of the finishing phase.

The reduction in feed conversion associated with physical castration means that animals consume more feed and produce more waste than natural boars for the same weight of meat produced – making production less sustainable and less environmentally friendly.

Finally, physical castration has attracted increasing attention from those who question its suitability on animal welfare grounds.

Consumer taste-test data

Consumers agree vaccination is the preferred method for controlling boar taint. In fact, consumers in Australia and New Zealand have enjoyed pork from vaccinated boars since 1998.³

Research from European and Asian countries during 2004 to 2008 revealed positive consumer reactions to the concept of vaccination as an alternative to castration. In fact, 61-77% of consumers in the countries prefer the vaccination approach compared to castration.^3,14

In addition, consumer taste panels are unable to distinguish any differences in the eating quality of pork from boars vaccinated against boar taint – in terms of smell, taste, juiciness and tenderness – and pork from pigs which have been physically castrated or from female pigs.^15-19
