The aim of this study was to characterize three different commercial dairy beef fattening systems for intensive Mediterranean fattening programs differing in gender, breed, nutrition, and days of feed in order to describe their performance, behavior, and carcass and meat quality when they were raised simultaneously under the same housing and care conditions. Treatments were three different production systems: (1) crossbred Holstein x beef breeds such as Charolais or Limousine heifers, slaughtered at 10 months of age (CBH10, = 41); (2) Holstein bulls, slaughtered at 11 months of age (HB11, = 42); and (3) crossbred Holstein x Angus bulls, slaughtered at 12 months of age (CAB12, = 37). According to our results, moving from a production system based on Holstein bulls to the crossbred Angus production system has no technical support as no large production and meat quality improvements were observed, and only marketing strategies for meat differentiation and consumer trends could favor this decision.
本研究的目的是对三种不同的商业乳肉兼用育肥系统进行特征描述，这些系统用于集约化地中海育肥项目，在性别、品种、营养和饲养天数方面存在差异，以便在相同的饲养和照料条件下同时饲养时，描述它们的生产性能、行为以及胴体和肉质。处理方式为三种不同的生产系统：（1）荷斯坦与肉牛品种（如夏洛来或利木赞）的杂交小母牛，10月龄时屠宰（CBH10，n = 41）；（2）荷斯坦公牛，11月龄时屠宰（HB11，n = 42）；以及（3）荷斯坦与安格斯杂交公牛，12月龄时屠宰（CAB12，n = 37）。根据我们的研究结果，从基于荷斯坦公牛的生产系统转向杂交安格斯生产系统没有技术支持，因为未观察到生产和肉质有大幅提升，只有肉类差异化营销策略和消费者趋势可能会支持这一决策。
