新的遗传工具有助于养牛,使其享有更强大的、可继承的豁免权,改善健康、福利和利润,同时又不牺牲增长。 A new genetic tool helps breed beef cattle with stronger, inheritable immunity, improving health, welfare, and profits without sacrificing growth.

由CSIRO与澳大利亚肉畜和澳大利亚安格斯伙伴开发的称为ImmuneDEX的新遗传工具帮助养牛,使其具有更强大、可继承的免疫反应。 A new genetic tool called ImmuneDEX, developed by CSIRO with partners Meat & Livestock Australia and Angus Australia, helps breed beef cattle with stronger, inheritable immune responses. 它通过评估抗体和以细胞为媒介的豁免,衡量免疫能力——动物如何能战胜疾病,特别是在断奶等压力下——评估抗体和以细胞为媒介的豁免。 It measures immune competence—how well animals can fight disease, especially under stress like weaning—by assessing both antibody and cell-mediated immunity. 研究表明,免疫能力强的牛的保健成本和饲料死亡率要低得多,而大部分保健费用是由免疫力低的动物造成的。 Research shows cattle with high immune competence have significantly lower health costs and death rates in feedlots, with low-immune animals driving most health expenses. 研究发现在增长或生产力方面很少或根本没有取舍,使育种者既能改善健康,又能改善业绩。 Studies found little to no trade-off with growth or productivity, allowing breeders to improve both health and performance. 该工具支持改善动物福利,减少抗生素使用,刺激经济回报,使之成为育种方案的宝贵补充。 The tool supports better animal welfare, reduces antibiotic use, and boosts economic returns, making it a valuable addition to breeding programs.
