**PolyPig aims to address a commercial and animal welfare need for sustainably produced feed to protect the health of piglets and improve survival and growth post-weaning.** This is desirable because of high mortality rates and disease incidence associated with early stages of pig development, due to factors such as oxidative stress that causes gut damage.Until recently, piglet feeds contained high levels of zinc oxide as an anti-microbial and growth promoter; however, this has been identified as a contributor to environmental contamination and antimicrobial resistance (AMR). Feeding of therapeutic levels of zinc oxide has been banned in Europe from June 2022; therefore, it is imperative that more sustainable alternative solutions are available.**The objective of PolyPig is to develop prior studies that demonstrated supplementation of piglet feed with polyphenols provides desirable protective effects; improving piglet gut health and survival.** Polyphenols are naturally occurring anti-microbial, anti-inflammatory, anti-oxidant compounds present in a wide range of plant materials, especially red beetroot. Large quantities of beetroot waste are generated from harvesting and processing for human consumption, exploitation of these by-products would provide a sustainable source of polyphenols for use as feed supplements.**A further objective is to implement sustainable methods for efficient polyphenol extraction from agri-food by-products (AFBPs).** This is necessary to separate the polyphenols from the plant fibre which is undesirable. Fibre inclusion in piglet feed exacerbates gut health problems associated with weaning. Previously developed energy efficient 'green' extraction and purification methods will be evaluated and optimised to enable large-scale processing of beetroot by­products.**The innovative combination of scalable biorefining of AFBPs for sustainable production of polyphenol supplemented piglet feed will create significant benefits for the farming community.** Improved productivity and growth, with enhanced meat quality and product shelf-life, enable increased exports of pig products and reduced importation. AFBP exploitation will generate additional revenue streams for farmers, divert waste from landfill and help achievement of net-zero carbon emission targets. PolyPig will initially focus on extraction of polyphenols from red beetroot, however, other agricultural and food waste-streams can also be exploited.Additional opportunities for innovative animal feed formulations and new product development will be generated, whilst the biorefinery engineering designs developed during this project will be scalable and applicable to novel by-products. **Manufacturing of innovative animal feeds based on AFBP-derived supplementation will help grow the UK economy and create employment opportunities, while supporting a transition to a low-carbon circular bioeconomy.**

**PolyPig旨在满足商业和动物福利对可持续生产饲料的需求，以保护仔猪的健康，提高断奶后的生存和生长。**这是可取的，因为与猪发育早期阶段相关的高死亡率和疾病发病率，由于氧化应激等因素导致肠道损伤。直到最近，仔猪饲料中含有高水平的氧化锌作为抗微生物和生长促进剂；然而，这已被确定为环境污染和抗菌素耐药性（AMR）的一个因素。自2022年6月起，欧洲已禁止食用达到治疗水平的氧化锌；因此，迫切需要更可持续的替代解决方案。** PolyPig的目的是开展前期研究，证明在仔猪饲料中添加多酚可以提供理想的保护效果；改善仔猪肠道健康和存活率。**多酚是一种天然存在的抗微生物、抗炎、抗氧化化合物，广泛存在于植物材料中，尤其是红甜菜根。大量的甜菜根废料是在收获和加工过程中产生的，供人类食用，对这些副产品的开发利用将提供多酚的可持续来源，用作饲料补充剂。**进一步的目标是实施从农业食品副产品（afbp）中高效提取多酚的可持续方法。**这对于从植物纤维中分离多酚是必要的，这是不可取的。仔猪饲料中含有纤维会加剧断奶时的肠道健康问题。以前开发的节能“绿色”提取和净化方法将被评估和优化，以实现甜菜根副产品的大规模加工。**可扩展的afbp生物精炼创新组合，用于可持续生产多酚添加仔猪饲料，将为养殖界创造显著效益。**生产力和增长的提高，以及肉质和产品保质期的提高，使生猪产品的出口增加，进口减少。AFBP的开发将为农民带来额外的收入来源，从垃圾填埋场转移废物，并有助于实现净零碳排放目标。PolyPig最初将专注于从红甜菜根中提取多酚，然而，其他农业和食物废物流也可以被利用。创新动物饲料配方和新产品开发的额外机会将产生，而在该项目期间开发的生物炼制工程设计将可扩展并适用于新的副产品。**生产基于afbp衍生添加剂的创新动物饲料将有助于促进英国经济增长和创造就业机会，同时支持向低碳循环生物经济过渡
