ACROSS-BREED TABLE 2004

with year 2002 Angus base

Dale Van VleckLarry Cundiff

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

3) Adjust MARC solutions to year 2002

MARC (ADJ) = MARC + b (EPD02Y -

EPDMARC)

Compares breeds as if had been year

2002 sires

4) Difference EPD for bull i from EPD02 (breed

Y)

MARC (ADJ,Y) + [EPD(Y,i) - EPD02Y]

5)Table adjustment for breed Y bull

relative to breed X (Angus)

bull:

[MARC (ADJ,Y) - MARC(ADJ,X)]

minus

[EPD02Y - EPD02X]

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)

Need estimates of

Direct heterosis

Maternal heterosis

1)From H by A diallels

(HH, HA, AH, AA)

Estimate direct heterosis;

3.0 lb for BWT

14.7 lb for WWT

30.4 lb for YWT

2) Adjust MWWT of cows from diallel for

direct heterosis

Estimate maternal heterosis; 23.0 lb

for MWWT

3) Adjust BWT, WWT, YWT for lack of direct

heterozygosityInclude 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
