1 Practitioners` Forum How can ET-praxis find his feet in the age of genomics? Frank Becker
2 Key data of European cattle reproduction 90 millions of cattle Dairy cows : 23 millions Beef cows : 15 millions 22 millions of first inseminations Dairy : 85 % vs Beef : 15 % Holstein : 8.7 ; Simmenthal : 2.8 millions ; Charolais : ; Limousine :
3 INFORMATION ABOUT YOUNG ANIMALS UNTIL 2 YEARS AGO PEDIGREES genomic analysis is possible immediately after fertilization selection is possible very early (in both sexes) young bull dams young AI bulls + NEW! PHENOTYPE GENOMIC INFORMATIO N CONSEQUENCES: genetic (breeding) progress can be doubled costs of breeding value estimation can be reduced by more than 90% KNUT ROSCHLAU, MASTERRIND Germany
4 STRATEGY FOR GENOMIC SELECTION OF EMBRYOS Embryos day 6 7 Biopsy of 10 cells Whole genome amplification (over night) Sexing (next day) Transfer of female embryos (without breeding value) Freezing of male embryos genome analysis calculation of breeding values Best only! Selection of male embryos for transfer
5 In vivo embryo production in bovine Number of flushed donors 2011: 23,480 Number of transferable embryos: 108,711
6 Example: 24 calves from 6 flushings or OPU/IVP sessions the calf with the highest breeding value was produced only in the 6th flushing/session (P.I. = pedigree index; gzw = genomic breeding value) +10 points gzw P.I. gzw -10 points Flushings and OPU/IVP sessions
