项目摘要
The pork industry is a major contributor to the Canadian agriculture economy, with an estimated farm gate income of about $3.5 billion per year. The Canadian meat processing industry has annual sales of almost $15 billion, about 40% of which is pork. Clearly, a successful pork industry is important to the overall Canadian economy. In addition, 50% of Canada's pork is exported to more than 90 nations worldwide, so it is essential that our industry remains financially competitive, produces a high quality product and maintains environment sustainability. The objective of this project is to develop an innovative and simple method for the determination of true sulphur amino acid requirements and bioavailability. Our approach is based on the broadly accepted understanding of sulphur amino acid metabolism, namely that sulphur amino acids supplied by the diet and absorbed in amounts that exceed the requirement for growth will be excreted in the urine as fre sulphate or related compounds. At the end of this project, we will provide a new approach for the determination of true sulphur amino acid requirement and bioavailability, and a method that probably could be used to determine the true amino acid requirements and availability of other amino acids by using urinary sulphate as an indicator. The concepts behind this proposed method are well established in humans and rats, s the likelihood of success is very good. Improved methods for the determination of true amino acid bioavailability has the potential to benefit Canada by providing an improved platform for the formulation of optimum feeding programs; this, in turn, will assist the pork industry in achieving the highest quality pork at the lowest possible cost, through optimum dietary amino acid content. Avoiding over formulation of amino acids will also contribute to environmental sustainability by reducing nitrogen excretion, a common outcome when diets are improperly formulated. This proposal will support the training of two graduate students plus summer students in animal nutrition, a field that continually experiences an inadequate supply of trained personnel
猪肉产业是加拿大农业经济的主要贡献者,估计农场每年的收入约为 35 亿加元。加拿大肉类加工业年销售额近150亿加元,其中约40%是猪肉。显然,成功的猪肉业对加拿大整体经济非常重要。此外,加拿大 50% 的猪肉出口到全球 90 多个国家,因此我们的行业保持财务竞争力、生产高质量产品并保持环境可持续性至关重要。该项目的目标是开发一种创新且简单的方法来测定真正的含硫氨基酸需求量和生物利用度。我们的方法基于对含硫氨基酸代谢的广泛接受的理解,即由饮食提供并吸收超过生长需求的含硫氨基酸将作为硫酸盐或相关化合物从尿液中排出。在该项目结束时,我们将提供一种确定真实含硫氨基酸需求量和生物利用度的新方法,以及一种可能用于以尿硫酸盐为指标来确定真实氨基酸需求量和其他氨基酸可用性的方法。这种方法背后的概念已经在人类和老鼠身上得到了很好的证实,成功的可能性非常大。测定真实氨基酸生物利用度的改进方法有可能为制定最佳喂养计划提供改进的平台,从而使加拿大受益;反过来,这将有助于猪肉行业通过最佳的膳食氨基酸含量,以尽可能低的成本生产出最高品质的猪肉。避免氨基酸的过度配制还可以通过减少氮排泄来促进环境的可持续性,氮排泄是饮食配制不当时的常见结果。该提案将支持动物营养领域两名研究生和暑期学生的培训,该领域一直面临训练有素的人员供应不足的问题
