Abstract 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.

高乳品遗传价值荷斯坦牛、标准乳品遗传价值弗里斯和夏洛莱 x 荷斯坦-弗里斯牛的肉质特征

摘要 在爱尔兰奶牛群中越来越多地使用荷斯坦遗传材料对牛肉生产产生了影响。总共有 42 头春季出生的公牛 [14 头荷斯坦牛 (HO)、14 头弗里斯兰 (FR) 和 14 头夏洛来 × 荷斯坦-弗里斯兰 (CH)] 在 26 至 37 月龄时进行屠宰。胴体重较高，脂质浓度为 m。CH 的胸最长肌和腰肌比奶牛品种低（P < 0.05）。与奶牛品种相比，CH 的总体可接受性往往较低（P = 0.055），而柔软度、质地和咀嚼性较低（P < 0.05）。CH 的 C16:1 在总脂质中的比例往往低于奶牛品种（P = 0.055）。
