The introduction of a routine genetic evaluation for specialized meat sheep (Blackheaded meat, Suffolk, Texel, Ile de France, Dorper, and Berrichon du Cher) and land sheep with focus on meat production (Merinoland) is described. Even though performance recording has existed for several production and fitness related traits and years, breeding values have not been officially available for sheep in Austria until 2017. Meat performance traits, recorded for purebred animals of both sexes, include average daily gain, fat depth and eye muscle depth. Historic computer tomography performance recording results serve as auxiliary traits. Regarding functional traits, lambing interval, number of lambs born and number of lambs born alive are considered. The routine genetic evaluation is carried out twice a year, at the beginning of January and at the end of June. Additionally, breeding values and reliabilities are calculated at weekly intervals but only uploaded if the change in reliability exceeds 5%-points or a new individual performance recording result is available. All estimated breeding values are standardised to relative breeding values with a mean of 100 (rolling base including rams aged 5–15 years), and a genetic standard deviation of 12, higher values are favourable. Apart from breeding values for individual traits, subindices for meat and fitness traits as well as a Total merit index (TMI) are calculated. For the calculation of the Meat index, the relative weights (in %) for average daily gain (direct) : muscle depth : fat depth are 36 : 62 : 2 for Merinoland and 44 : 52 : 4 for meat sheep. For fat depth, the breeding values are transformed to an intermediate optimum in the index calculation. In the Fitness index, the relative weights (in %) for lambing interval : lambs born maternal : lambs born paternal: lambs born alive maternal : lambs born alive paternal are 35.0 : 33.3 : 8.3 : 18.3 : 5.0 (Merinoland) and 20.0 : 49.0 : 17.0 : 10.0 : 4.0 (Meat sheep). Including the trait average daily gain maternal in the meat complex, the relative weights (in %) of Meat : Fitness are 40 : 60 and 60 : 40 in Merinoland and Meat sheep, respectively. The TMI was defined in a way so that the calculated selection response is positive for all single traits in order to avoid an unfavourable development. Thus, it serves as a starting point for a breeding objective that is both, economically feasible and sustainable in the long-term. Further traits that may be considered in a future TMI are e.g. longevity and selected conformation traits.

介绍了对专业肉羊（黑头肉、萨福克、特塞尔、法兰西岛、杜珀和 Berrichon du Cher）和以肉类生产为重点的陆地羊（美利奴羊）的常规遗传评估。尽管性能记录已经存在多个与生产和健康相关的特性和年份，但直到 2017 年奥地利绵羊的育种值才正式可用。记录的纯种两性动物的肉类性能特性包括平均每日增重、脂肪深度和眼肌深度。历史计算机断层扫描性能记录结果作为辅助特征。关于功能性状，考虑产羔间隔、出生羔羊数和活产羔羊数。每年进行两次常规遗传评估，在 1 月初和 6 月底。此外，育种值和可靠性每周计算一次，但仅当可靠性变化超过 5% 或有新的个体性能记录结果可用时才会上传。所有估计的育种值均标准化为相对育种值，平均值为 100（滚动基础包括 5-15 岁的公羊），遗传标准偏差为 12，较高的值是有利的。除了单个性状的育种值外，还计算了肉类和健康性状的子指数以及总价值指数 (TMI)。对于肉类指数的计算，平均日增重（直接）：肌肉深度：脂肪深度的相对权重（百分比）为 36 : 62 : 2 美利奴兰岛和 44 : 52 : 4 肉羊。对于脂肪深度，在指数计算中，育种值被转换为中间最优值。在适应度指数中，产羔间隔的相对权重（以 % 计）：母体出生的羔羊：父系出生的羔羊：母体活产的羔羊：母体活产的羔羊：35.0 : 33.3 : 8.3 : 18.3 : 5.0 (Merinoland) 和 20.0 : 49.0 : 17.0 : 10.0 : 4.0（肉羊）。包括肉类复合物中母体的性状平均每日增重，Meat : Fitness 的相对权重（%）在 Merinoland 和 Meat 绵羊中分别为 40 : 60 和 60 : 40。TMI 的定义方式使得计算出的选择响应对于所有单个性状都是正的，以避免不利的发展。因此，它作为育种目标的起点，在经济上可行且长期可持续。
