Transcription

1 Genomic Management: Impact on Sustainability David C. Thorbahn, Select Sires Inc. 1

2 Definition of Sustainability: the ability to survive, be sustained, be supported, or confirmed the quality of not being harmful to the environment or depleting natural resources, and thereby supporting longterm ecological balance The Three P s of Sustainability the economic - Profit the social - People the environmental - Planet 2

3 Survival in the Dairy Business Low Cost/most profitable Differentiate All have to be environmentally and Mom friendly Presentation Genetics Works Required for Long-Term Profit Maximization Genetic audits required like financial audits Breed for total profitability Selection Index for total profit New Methodologies of Application and Delivery Better for the environment/mom Friendly Lowers the Carbon Footprint Healthier cows and Healthier Product 3

4 Turning Records Into Genetic Information Performance Pedigree Animal s True Genetic Merit Progeny Genomic Evaluation Process Estimate 60,000 SNP Effects Build a Reference Population 40,000 AI Bulls 500,000 Cows w/records DNA Test Young Animals Compute Genomic Evaluations then Make Selection Decisions 4

6 What if you could: (What is it worth to you)? Increase production by 6 to 10 lbs per cow per day? Increase Pregnancy Rates by 5 to 10%? Increase Conception Rates by 4 to 6%? Decrease days open by 20 to 25 days? Reduce sold and died cows by 200% or more and Have cows with limited health events? Proof that Genetics Works Tracking the genetic performance with data from the Actual Dairy Comp backup file 6

7 Accurate Data is a MUST! (Parentage ID) Select Sires PGA Testing Results from 883 Animals/64 Herds was Misidentified 17.9% of the time. Range: 100% to 1% Sire ID National Average Misidentification 24.9% Updates: Genetic Tools Pedigree Index: ½ the sire, ¼ MGS Accuracy 12.5% to 25% Acc. Parent Average: ½ Sire PTA + ½ Dam PTA 20% to 40% Acc. Genomic Test: DNA analysis 55% to 75% Acc. 100% accuracy in Parent ID 7

16 How do I go faster? Female Selection Options: Sexed Semen & Beef Semen Breed top genetic animals sexed Breed remaining to highest value offspring Embryos Commercial goal embryos - High NM$ F1 Cross embryos for replacements Remaining animals are profit opportunities 16

17 Sexed Semen & Beef Semen Considerations Rank animals in herd genetically Use PI, PTA or genomic test to rank Use a replacement calculator for heifer needs Develop a program to market excess offspring Market will be loaded with Dirty Holsteins Advantages of Dairy Beef over Beef Holsteins are inbred and naturally high on tenderness gene 100% A.I. Babies vs 60% A.I. or less 100% consistent traceability 100% genetic traceability Vaccination protocol Mineral supplementation Health record protocol Genetic specifications Traits: Fert, CE, weaning wt., carcass quality 17

18 Make Everything Produced a Profit Center! Dairy/Beef Planning When do you sell? Wet Calves Price is most vulnerable/hard to be a price maker Hard to take advantage of your management pound feeder calves Premium: Lot Loads 50,000# ( consistent head) Fat Steers New Programs and Deliveries Embryos Delivery mechanism Real and will grow Offers choice of genetic level and hot weather fertility F1 crossbreds Concerns: Cost of reproductive performance Management is more intensive Cost per pregnancy vs return 18

19 Sustainability must be environmentally and Mom friendly 19

20 What public is fed? GMO Free (Wines/Plants only) Hormone free (No rbst) Antibiotic Free (Test every tanker load) We must inform the consuming public! High Protein (Whey Protein) Cancer fighting (Its in the fat-clfa) Fat Free (value in fat?) Gluten free Naturally Sugar Free (Fairlife) Genetics Can Make Healthier/Happier Cows Lower disease incidence Lower lameness GMO Free Healthy cow is a happy cow High traceability Good for the environment 20

Bauman*2 Take Aways Get an annual Genetic Audit Genetics Work - Use the best genetics Use a complete value-based selection index Selecting females can make faster progress Use SCR as a unbiased tool Make every thing you produce a profit center Help inform consumers 21
