The increased use of Holstein genetic material in the Irish dairy herd has consequences for beef production. In all, 42
spring-born steers [14 Holsteins (HO), 14 Friesian (FR) and 14 Charolais × Holstein-Friesian (CH)] were reared to slaughter
at between 26 and 37 mo of age. Carcass weight was higher and the lipid concentration of m. longissimus thoracis
et lumborum was lower (P < 0.05) for CH than the dairy breeds. Overall acceptability tended to be lower (P = 0.055) while
tenderness, texture and chewiness were lower (P < 0.05) for CH compared with the dairy breeds. The proportion of
C16:1 in the total lipid tended to be lower (P = 0.055) for CH than the dairy breeds. Replacing male offspring of traditional
“Irish” Friesian bulls with offspring from a genetically superior (from a dairy perspective) strain of Holstein bull had no
commercially important impact on beef nutritional or eating quality.
