Economic modelling
�Modelled at the margin
�ABS 2001 numbers
�Stop at farm gate (excludes zoonosis, regulation)
�Annual average costs
�Flock/herd average cost
�10 yr average prices

National cost of disease to the sheep industry
The cost of peri-natal lamb mortality represents the return to industry for a
10% increase in lamb survival

Animal Health & Welfare Strategic
Plan 2007-12
Program Goal
•AWI will successfully address current and future animal welfare
related issues, including:
–By December 2008 100% of woolgrowers who conventionally mules
their own sheep will have had access to the accreditation training
package through the National Mulesing Accreditation Program
–By 2010 100% of woolgrowers who previously carried out surgical
mulesing will have adopted a new technology for breech fly strike
control
–By 2012, 30% of woolgrowers will have increased neonatal and weaner
lamb survival to at least 85%
•By 2012, 30% or 12,000 woolgrowers and 200 service providers will
have adopted an AWI innovation that has reduced the national on-
farm economic impact of internal and external parasites by $100
million annually

Mulesing
Aim
•Improve and replace current mulesing
practices through a combination of
accreditation, new products and breeding
options

Welfare study
Conclusion for clips
“…the clip treatment has only a mild impact
on the biology of lambs and thus the
welfare risks are considered relatively
minor…”
![Page 17: Dr Joan Lloyd DVM MVS PhD Program Manager Animal …Parasite Control Aim • Develop new extension materials, tools and product s for use by woolgrowers and their advisors to reduce](https://reader030.fdocuments.in/reader030/viewer/2022011921/6038fe9dfc797975e80c94a6/html5/thumbnails/17.jpg)
Parasite Control
Aim
•Develop new extension materials, tools and products for
use by woolgrowers and their advisors to reduce the
economic impact of internal and external parasites
Projects
•Extension of IPM strategies
•Improved test to monitor worm burdens in sheep
•Fungal bio-pesticide for control of lice
•Identification of novel targets for development of new
anthelmintics and insecticides
•Lice detection test
![Page 18: Dr Joan Lloyd DVM MVS PhD Program Manager Animal …Parasite Control Aim • Develop new extension materials, tools and product s for use by woolgrowers and their advisors to reduce](https://reader030.fdocuments.in/reader030/viewer/2022011921/6038fe9dfc797975e80c94a6/html5/thumbnails/18.jpg)
Shelter
•Issue raised by both producers and
welfare groups
•Important for the survival of ewes and
lambs, especially during inclement
weather
•Addressed through lamb and weaner
survival program in new Sheep CRC
![Page 19: Dr Joan Lloyd DVM MVS PhD Program Manager Animal …Parasite Control Aim • Develop new extension materials, tools and product s for use by woolgrowers and their advisors to reduce](https://reader030.fdocuments.in/reader030/viewer/2022011921/6038fe9dfc797975e80c94a6/html5/thumbnails/19.jpg)
Tail Docking
•Essential for flystrike control
•Most recent survey of Australian sheep
producers in 2002
–50% sheep docked with rubber ring
–27% sheep docked with gas knife
–22% sheep docked by knife or shears
–52% dock at recommended joint
•Welfare outcome (behaviour and cortisol)
–Gas knife > rings > knife
![Page 20: Dr Joan Lloyd DVM MVS PhD Program Manager Animal …Parasite Control Aim • Develop new extension materials, tools and product s for use by woolgrowers and their advisors to reduce](https://reader030.fdocuments.in/reader030/viewer/2022011921/6038fe9dfc797975e80c94a6/html5/thumbnails/20.jpg)
Tail Docking (cont’d)
•Phasing out of mulesing presents an
opportunity to improve tail docking
•As part of development of alternatives to
mulesing AWI has developed a modified
gas knife
•Use of this and improved technique will be
promoted alongside the mulesing
alternatives

The breeding ewe plays a pivotal role in the w
ool
production system
It m
akes good sense to have her in the right condition at
the right time as her condition affects;
•reproduction levels and lamb survival
•wool production of herself and her progeny
•pasture utilisation and efficient use of feed
resources

increase productivity and profitability of the M
erino

Predation by foxes and feral dogs
•Ranked highly as a welfare issue by
producers
•Estimated to cost >$30m annually
•AWI will continue to work with the Invasive
Animals CRC for a more humane toxicant
to replace 1080

Summary
•AWI’sAnimal Health & Welfare Strategic Plan
aims to reduce economic cost of disease and to
address priority welfare issues
•Some conditions are both of high economic cost
and a welfare issue
•Generally speaking, producers and welfare
groups are in agreement as to the high priority
welfare issues
•AWI is making progress in several areas,
including alternatives to mulesing, improved
parasite control, tail docking, ewe nutrition and
predation
