How responsive is the conception rate of your Merino ewes?

Summary

The NSW Lifetime Wool project has clearly demonstrated that there is a strong relationship between body condition at joining and the subsequent conception rates of Merino ewes. However, the mechanism driving the increase in conception differs between maiden and adult ewes.

Another important finding from these various analyses has been the amount of variability occurring between Merino flocks in the magnitude of the response to ewe condition at joining.
