Extract

Nose ringing is widely used in conventional outdoor pig production as the only reliable method of preventing sows destroying pasture by rooting (Edwards et al., 1998), but is prohibited by some organic sector bodies as it inhibits the sows’ behaviour. Some organic producers use a rotation policy in which the sows are moved to fresh pasture about three times a year, after green cover has been destroyed. As well as limiting nutrient leaching, frequent movement also limits parasite build-up in a system which prohibits the routine use of anthelmintics. However, it has a high labour demand. An alternative strategy is to maintain the sows on a larger area for the whole year. This abstract presents initial data on comparison of the two systems regarding annual pattern of pasture damage by sows.
