Engineering safer pastures for livestock

该项目旨在开发地下三叶草与提高浓缩单宁在叶子。由于低浓缩单宁和高可溶性蛋白质，这种重要的牧草豆科植物目前对牛羊有腹胀风险。腹胀是一种健康问题，每年给澳大利亚和新西兰的畜牧业造成超过2亿美元的损失。缩合单宁可以减少膨胀，降低甲烷产量，提高生产效率。一种利用CRISPR和其他创新分子技术的新方法将产生浓缩单宁含量高的育种品系，并提供适用于其他牧场豆类的知识。牲畜生产者的预期结果包括改善动物福利、减少碳排放和提高利润。

This project aims to develop subterranean clover with elevated condensed tannins in leaves. This important pasture legume is currently a bloat risk for cattle and sheep due to low condensed tannins and high soluble proteins. Bloat is a health issue that costs the Australian and New Zealand livestock industries over $200 million per annum. Condensed tannins can reduce bloat, decrease methane production and improve efficiency of production. A novel approach using CRISPR and other innovative molecular techniques will generate breeding lines high in condensed tannins and deliver knowledge applicable to other pasture legumes. Expected outcomes for livestock producers include improved animal welfare, reduced carbon emissions and enhanced profits.
