Risks, Myths, and Opportunities

What’s it all about?

Page 3: Pregnancy Diagnosis in Export Feeder Cattle · 100% accuracy (NDP) in cattle < 6 weeks pregnant •Ultrasound Good for detecting most pregnancies (contrasting uterine fluid) Difficult

Animal Welfare Risks• Unsuitable environment and poor

outcomes for neonatal calves

export depots

livestock vessels

destination feedlots

• Inadequate skills and resources to care for neonatal calves

• Risk of poor outcomes for cow due to abortion, dystocia, metritis etc.

Quantifying the Problem?

• Anecdotal reports common, investigations rare

• Data not available

Depots and RP’s?

Shipboard?

ESCAS?

Total females exported?

• Spectrum of skills and accuracy of pregnancy testing

NT/WA accredited testers, vets, PregCHECK® vets

Myths & Misconceptions

• You don’t need a vet degree to pregnancy test

Basic skills (90% accuracy) versus Competency (100% accuracy)

• 100 % accuracy is not achievable

Competency = 100% (>99.9% is reasonable goal)

• Vets are not accessible, or too expensive

470 PregCHECK® accredited vets around Australia

vets are cost competitive with non-veterinary contractors

ACV position: If PregCHECK ® accredited;

Pre-export period 30days 45days, no additional risk

Page 6: Pregnancy Diagnosis in Export Feeder Cattle · 100% accuracy (NDP) in cattle < 6 weeks pregnant •Ultrasound Good for detecting most pregnancies (contrasting uterine fluid) Difficult

Technique vs Technology• Manual palpation

the Gold Standard for non-pregnant cattle Palpation of the entire non-pregnant uterus 100% accuracy (NDP) in cattle < 6 weeks pregnant

• Ultrasound Good for detecting most pregnancies (contrasting uterine

fluid) Difficult to examine entire non-pregnant uterus Poorly suited for export feeder cattleMay be used by a veterinarian only. See EAN 2016-22

• Blood Testing ~99% accuracy, depending on stage of pregnancy not diagnostic in ~4% of animals (need rechecking) Poorly suited for export feeder cattle

Techs Vs Vets

• Competent testers* allowed in NT & WA, but not QLD

79 accredited by NT DPI&F

4 approved by WA Vet Surgeons Board

QLD Vet Surgeons regulations under review

CCA and MLA exploring national accreditation options

• Some Contractors and DIY testers highly competent, but quality of testing is variable

• Training is minimal and assessment standards are poor

So what?

• Manual palpation is the most suitable method

• PregCHECK® Accredited Vet = Gold Standard

• Other providers can be good/bad/indifferent

• PDx for Certification versus Management?

• A Veterinary Certificate;

= Credibility

= Accountability

= Liability

Challenges and Opportunities

• Calving’s and unmanaged pregnancies are preventable and unacceptable

• Squandered opportunity to utilise existing data

• Morbidity data is no good unless you do something

with it (data systems and epidemiological analysis)

• What is industry’s tolerable limit?

• How do we achieve that?
