Cow’s Own Worth (COW) Designed to represent more closely the future phenotypic performance of dairy females

A new system to rank females on predicted profit potential

  • Spring-calving system
  • EBI – Economic Breeding Index

(national breeding index)

  • Centralised database
  • Reward data recording herds

with an added value service

COW was able to identify cows performaing well COW was able to identify cows for culling I would use COW to help inform culling decisions if it were available from ICBF The report easy to read The summary tables were useful to highlight specific areas of production The colour coding of the top and bottom 10% on traits was useful My milk recording has more value now that I can receive COW I would like COW to be generated for my herd from now on I would recommend the national extension of the COW in 2017

Conclusions

  • Complimentary to the EBI (national breeding index)
  • Added value service
  • Prospects to improve herd profitability
  • Multiple sources of data available
  • Live system
  • Maximise COW accuracy by;
  • Recording MORE data
  • Recording ACCURATE data
  • Pilot phase of on-line service July 2017
  • Commercial roll-out September pending results of pilot phase
