The WormFEC Programme is provided by AgResearch in association with Beef & Lamb New Zealand (Sheep Improvement Limited – SIL). This service provides breeding values for several parasite resistant traits, along with an overall index of resistance.
A faecal egg count (FEC) index is calculated for individual sheep. FEC data is registered with SIL along with data collected for other traits (e.g. lamb growth, twinning rate etc.) to generate breeding values that can be applied to assist in stock management decision making.
