Genetic improvement of pea to replace soyabean in the diets of poultry and monogastric livestock (PeaGen)

提高农业生产力和可持续性对于应对气候变化带来的全球粮食安全挑战至关重要。豆类作物是人类和动物植物蛋白质的重要来源。随着世界对动物产品需求的增加，对作为动物饲料的植物蛋白的需求也在增加，英国与其他国家一样面临国内植物蛋白生产能力的不足。在欧盟，70%的动物蛋白质是进口的，主要是大豆或豆粕，豆粕占英国牲畜饲料蛋白质的33%。2011-12年度，英国进口大豆产品达到183万吨，其中大部分是从南美进口的转基因大豆。增加英国种植的蛋白质数量以取代进口大豆产品被认为是英国动物饲料行业面临的主要挑战。在本LINK提案中，我们将开发和应用新的遗传方法来提高豌豆（Pisum sativum L.）的营养价值（蛋白质和水溶性碳水化合物）。种子，以增加豌豆作为动物饮食中的高质量饲料的使用，减少英国因进口大豆产品而造成的蛋白质短缺，并为畜牧生产系统带来环境效益。该提案建立在BBSRC，欧盟，Defra，Innovate UK和levy board资助的豆类遗传学和农艺学研究中获得的知识基础上，这些研究导致了具有更高蛋白质含量的豌豆新品系的开发。我们将利用我们在植物基因组学、豌豆遗传育种、农艺学、植物化学和动物营养学方面的专业知识，将具有改良谷物成分的种质整合到改良的豌豆品种中。我们将与来自家禽和养猪业的行业合作伙伴以及作物开发商一起，分析在饲料配给中用这些新的豌豆品种取代大豆对单胃和家禽生长的影响，以及将其纳入的经济和环境影响。虽然重点是家禽和单胃动物，但该项目将提供关于将这些新的豌豆品系纳入其他部门（反刍动物和水产养殖）的价值的信息。

Higher agricultural productivity and sustainability is critical to meeting the global challenges of food security in the presence of climate change. Legume crops are a critical source of plant-based proteins for people and animals. As the world demand for animal products increases, the demand for vegetable proteins as animal feedstocks also rises and the UK in common with other countries faces a shortfall in domestic vegetable protein production capability. In the EU 70% of the protein fed to animals is imported, mostly soyabean or soya meal with soya meal accounting for 33% of the protein in UK livestock feeds. In 2011-12 UK imports of soya products reached 1.83 million tonnes, the majority of this being transgenic soya imported from South America. Increasing the amount of UK grown protein to replace imported soya products is recognised as a major challenge for the UK animal feed sector. In this LINK proposal we will develop and apply new genetic approaches to enhance the nutritional value (protein and water soluble carbohydrate) of the pea (Pisum sativum L.) seed, to increase the use of pea as a high quality feed in animal diets, reducing the UK protein deficit from the import of soya products and also delivering environmental benefits to livestock production systems. The proposal builds on knowledge gained in BBSRC, EU, Defra, Innovate UK and levy board-funded research on the genetics and agronomy of pulses that have led to the development of novel lines of pea with higher protein content. We will use our expertise in plant genomics, pea genetics and breeding, agronomy, plant chemistry and animal nutrition to integrate the germplasm with improved grain composition into improved pea varieties. With industry partners from the poultry and pig sector as well as crop developers, we will analyse the impact of replacing soya with these new pea varieties in feed rations on the growth of monogastrics and poultry and the economic and environmental impact of their inclusion. Although the focus is on poultry and monogastrics, the project will provide information on the value of including these new pea lines for other sectors (ruminants and aquaculture).
