New sheep AI booklets aim to boost on-farm breeding success

Sheep Central, September 20, 2021

NEW handbooks aimed at improving the success of artificial sheep insemination (AI) practices have been released in South Australia.

The SA Sheep Industry Fund and its project partners – Primary Industries and Regions SA and the South Australian Research and Development Institute – have created the Improving the Success of Sheep Artificial Insemination Programs handbooks.

The handbooks are aimed at AI practitioners and sheep producers, and provide a range of information on how to synchronise the oestrus cycle in flocks and to improve results in an AI program.

The project partners said the handbooks will help producers to know when their flocks are cycling and ovulating and will provide other ways to improve AI outcomes.

They will also provide ways for producers and practitioners to understand what is happening in the oestrus cycle when programming ewes for AI.

Co-author of the handbooks, SARDI’s Dr Jen Kelly, said the information would be invaluable for both producers and AI providers.

“They will increase the understanding of the oestrus cycle and follicle development as well as the timing of AI to increase commercial outcomes,” she said.

A brief economic analysis by the SARDI Reproduction Research Team with assistance from the South Australian Stud Merino Breeders Association accompanies the handbooks.
Dr Stephen Lee, University of Adelaide, prepared the section on genetic gain.
