Evidence-based approach to investigating poor reproductive performance in maiden ewes
Date presented 2022
2022 Sheep, Camelid and Goat Veterinarians Conference, 22/06/2022–24/06/2022, Stamford Grand Adelaide, Glenelg
Improving ewe reproductive performance remains a priority for the Australian sheep industry. Here we present a protocol for veterinary practitioners to investigate cases of poor reproductive performance. The proposed methodology can be readily adapted to account for resources available and risk factors specific to the farm in question. This protocol will allow practitioners to determine the (a) timing and (b) likely causes of foetal/lamb loss to inform strategies targeted at improving reproductive performance.

The Merino Lifetime Productivity project is evaluating the lifetime productivity of the ewe progeny of industry sires at five sites around Australia. Additional work at the Pingelly site is evaluating the productivity of the wether progeny. Liveweight, carcase traits and wool production data for wether progeny born in 2016 and 2017 have been collected. This paper presents a preliminary analysis of the value of production of the 2016 and 2017 drop wethers at yearling and adult age. The difference in value of production to 18-22 months of age between the top and bottom ranking sire groups was approximately $50 per head, excluding differences in mortality between sire groups. In future analyses the wether data will be compared to the productivity of the ewes as well as combined with ewe data to calculate flock profitability so comparisons can be drawn between sires in feed intake and whole-body energy.
