  3. Introduction � After a long period of stability � Many changes in dairy production including 3 majors innovations � Genomic Selection � Sexed semen � Precision dairy farming � What are the impacts of this technologies ? � How their combinations can change dairy farming ? CSC Nuffield, 4th March 2015, Reims, France

  4. Dairy cattle in France Normande 430,000 cows 56% r ecorded Milk: 6,176 kg Montbéliarde 670,000 cows, 61% recorded Milk: 6,158 kg Holstein 2,500,000 cows, 68% recorded 10 local breeds Milk: 9,125 kg 150,000 cows 72,000 dairy farmers, 3,686,000 dairy cows CSC Nuffield, 4th March 2015, Reims, France

  5. Trend in France � Increasing of herd size, Herd size (dairy cattle in performance recording) � Divide by 2 of pick up points for the same volume (28 Ml) � 50 000 pick up points 1990 to 25 000 in 2020… CSC Nuffield, 4th March 2015, Reims, France

  6. Genomic selection CSC Nuffield, 4th March 2015, Reims, France

  7. What is genomic selection? Effect of each marker to estimate Candidates Young animal with +2 only genotypes -3 +2 +3 Reference population +5 +1 Bulls with +4 -2 Genotypes + Phenotypes (average daughter GEBV = performances) ∑ marker effects + polygenic effect Calibrate prediction equations CSC Nuffield, 4th March 2015, Reims, France

  8. Steps toward Genomic Selection in France Genomic selection Marker Assisted Selection 35 traits, (MAS 2) 300-400 QTL/traits 25 traits, 30-40 QTL /traits From 2010 (males) Marker Assisted Selection (MAS R ² : 2008 -2010 1) +0.30,0.40 8 traits, 5 QTL /traits R ² :+0.20, 2001 -2007 From 2011 (females) 0.30 1996 -1999 R ² :+0.05 Fine Mapping R ² : ++0.10 Pre-selection tool: full brothers + affordable chip selection before QTL detection testing CSC Nuffield, 4th March 2015, Reims, France

  9. Breeding programs in dairy cattle without Genomic Selection PROGENY TESTING PROGRAM: ➢ A costly process: maintaining 10 bulls to ➢ A long process: > 5 years X Mated to 400 cows 100-150 daughters get proofs only use 1 for AI ⇒ USE FOR AI birth 2 years 5 years Age of the bull SELECTION Estimation of breeding values CSC Nuffield, 4th March 2015, Reims, France

  10. ➢ Breeding values Genomic Selection: a revolution available for all traits routinely evaluated ➢ For males and females, with the same accuracy ➢ A shortened generation interval ➢ A better accuracy at the X time of pre-selection (compared with Parent Average) birth 2 years ⇒ USE FOR AI 5 years ⇒ An increased genetic Age of the bull 3 months: gain! Estimation of breeding values, from genomics CSC Nuffield, 4th March 2015, Reims, France

  11. European reference population From 2009, European breeding partners (breeding associations, computing centers, breeding companies) have decided to join their forces to share: - data (reference population, 54k, bulls) - and know-how (tight collaboration with research centers and universities) CSC Nuffield, 4th March 2015, Reims, France

  12. A specific organization for research and operation • Research Co-funding – INRA ALLICE – INRA ALLICE APIS-GENE (GIS AGENAE) • Transfert and roll-out • Operation – UMT 3G – SAS • Capital by Breeding companies 
 who invested in the research – Valogène – Exclusive licence of operation for 5 years

  13. Large return on investment � Inovative points � Share cost of genetic evaluation with farmer organization (250 k € /year) � Royalties for intellectual property linked to research (350 à 400 k € /year) � to invest on the next steps � Reduction of expenses for French farmers Royalty paid in APIS-GENE � International cooperation 4ème génération � buying Chips cumul : 1 208 K € � New tools (EuroG10k) � VALOGENE has a commercial activity

  16. Impact on cows Number of females genotyped for herd management… Genotyping for farmers ● Interest of the female 55,000 genotying: 49,985 ⇒ Herd management, 41,250 ⇒ heifers sells, ⇒ mating, 34,662 ⇒ … 27,500 Increasing selection intensity 26,329 Accuracy of GEBV More genetic progress 13,750 2,166 00 2011 2012 2013 2014 CSC Nuffield, 4th March 2015, Reims, France
