Genetic improvement of Canadian lamb carcass yield, quality and growth traits

在加拿大羊肉产业中，胴体产量和质量性状相当重要，因为这些性状直接关系到供应链的生产效率、经济盈利能力和消费者对国内产品的选择。然而，尚未对加拿大品种和加工系统的羔羊胴体产量和质量性状的商业性能和遗传学进行大规模评估。本研究旨在基准表型和检查胴体产量，脂肪深度和构象的遗传基础，在商业羔羊，并考虑与早期生长，超声波测量和其他经济上重要的生产和繁殖性状的遗传关系。本研究的目的是寻找最佳的选择方法，以提高商品羔羊育种计划中的胴体产量和质量。

In the Canadian lamb industry, carcass yield and quality traits are of considerable importance because these relate directly supply chain production efficiency, economic profitability and consumer choice of domestic products. However, a large-scale evaluation of commercial performance and genetics of lamb carcass yield and quality traits has yet to be conducted for Canadian breeds and processing systems. This study seeks to benchmark phenotypes and examine genetic bases of carcass yield, fat depth and conformation in commercial lambs, and consider genetic relationships with early growth, ultrasound measurements and other economically important production and reproduction traits. The goal is to find optimal selection methods to improve carcass yield and quality in commercial lamb breeding programs.
