Q. Is beef cow progress high enough?
A. No
- Why?
- Lack of culling for productive traits because:
- A herd calving at 80% culls its "average cow(being empty) after three calves
- A herd calving at 90% culls its "average" cow after 7 calves
- A herd calving at 95% culls its "average" cow after 13 calves
Every cow culled as empty can not be culled on productive traits.
Are we buying bulls from cows that have got in calf every year of their life?
- Constitution and longevity
- Every cow culled for a physical problem(feet, udder, etc) takes the place of a production trait cull
- Buy bulls from long lived sound dams.
- Sire and Dam selection
Is there a variation in feed intake per kg of body weight?
Yes
Refer Steve Morris Australian Meat Research Centres
We can only improve this efficiency factor via stud herds.
- Beef cow traits critical to farming profits on hill country
- Converting grass to profit
Beef cows will never produce mat from grass as efficiently as finishing animals on high producing pastures. Breed cows that will perform on lower quality feed, not high quality feed.

- Conclusions:
- Efficient beef cows stack up well in profitability against finishing stock, but will not, and should not compete for profit against a high growth steer.
- When utilising poor quality feed, even poorer efficiency beef cows compete with finishing steers
- By definition, beef cows will never convert grass to meat as efficiently as steers or bulls on good grass, buy are very competitive on poorer grass.
- Take Home Messages
The result is in your control
- Make your cows more efficient
Better cow culling
Better bull selection
Better utilisation of feed
Don't breed big soft cows(workers are required)
Use terminal sires where not breeding for the FSB market
- Organise your livestock system to suit the country
Cows won't compete with high performance ewes and finishing cattle on good pastures
They outperform, and are complimentary, on poorer quality feed.
