3. Basic Information 1)Breed of sire solutions from MARC Represent samples of sires 2)EPD from breed associations EPD for animals born in 2002 EPD for bulls used at MARC Difference represents "what if“ year 2002 bulls had been used at MARC

4. 3)Adjust MARC solutions to year 2002 MARC (ADJ) = MARC + b (EPD 02Y - EPD MARC ) Compares breeds as if had been year 2002 sires 4)Difference EPD for bull i from EPD 02 (breed Y) MARC (ADJ,Y) + [EPD(Y,i) - EPD 02Y ]

5. 5)Table adjustment for breed Y bull relative to breed X (Angus) bull: [MARC (ADJ,Y) - MARC(ADJ,X)] minus [EPD 02Y - EPD 02X ]

6. 6)Compare individual bulls (i, j, k) i, breed Y j, breed Z k, breed X (Angus) Table for Y+ EPD(Y, i) Table for Z+ EPD(Z, j) 0+ EPD(X, k) (Angus)

11. 3)Adjust BWT, WWT, YWT for lack of direct heterozygosity Include HH, AA calves Proceed with across-breed analyses 4)Adjust MWWT for lack of direct and maternal heterozygosity Include HH, AA cows Proceed with across-breed analysis
