Reproduction

The ewe flock forms the hub of a breeding enterprise and represents a significant capital investment for a farm business.

After selecting the best ewes, managing them for optimal performance is paramount for profitability.

Considerable research, in particular from the Lifetime Wool project, has shown that greater profits can be gained by managing ewe body condition score and weaner growth rates as well as pregnancy scanning to better allocate nutritional resources to late pregnant ewes.


Profits result from:

  • improved conception and twinning rates
  • increased wool returns from the ewes
  • greater survival of lambs at both lambing and beyond weaning,
  • improved performance of lambs for weight and wool over their lifetime
  • fewer losses of ewes around lambing
  • increased ability of ewes to recover and join again the following year.

Major upgrade on the way for RamSelect.com.au
Commercial sheep breeders could soon have access to a new DNA test that profiles the average genetic merit of their flock. This new information will increase the precision with which rams can be selected to have the greatest impact on flock performance. The DNA test results will feature in an upgraded RamSelect app, which will also allow breeders to store details of flock rams and their genetic merit in order to make better...
