猪鸡低蛋白配合饲料团体标准发布

2018-10-26 20:41:01    新华网

新华社北京10月26日电(记者 胡璐、董峻)中国饲料工业协会26日发布《仔猪、生长育肥猪配合饲料》《蛋鸡、肉鸡配合饲料》两项团体标准,聚焦降低配合饲料蛋白含量,倡导高效低蛋白日粮体系应用。

中国饲料工业协会有关负责人说,我国工业饲料以及肉、蛋产量连续多年位居全球第一,但饲料资源长期短缺,特别是蛋白饲料原料的进口依存度接近80%,成为制约我国饲料工业和养殖业发展的瓶颈。同时,饲料利用效率不高不仅增加养殖动物代谢负担,而且导致养分大量过腹排放,带来了比较突出的环境影响。随着科学研究不断深入,特别是低蛋白日粮配制技术发展,在合理添加合成氨基酸和酶制剂的前提下,配合饲料中粗蛋白和磷的水平可以显著降低。

为减少饲料原料特别是蛋白质饲料原料的消耗,破解养殖业的环境约束,建立可持续发展的产业体系,中国饲料工业协会联合国内动物营养领域专家及大型饲料企业,共同起草了《仔猪、生长育肥猪配合饲料》《蛋鸡、肉鸡配合饲料》两项团体标准。与现行的国家标准相比,两项团体标准增设了粗蛋白质、总磷上限值,下调了部分指标的下限值,增加了限制性氨基酸品种,重新划分了动物生长阶段,增加了我国特色养殖品种黄羽肉鸡的相关指标。

相关研究结果及国内养殖企业应用实践表明,该标准的指标设置完全可以满足养殖动物生长需求,不会降低生产性能和产品品质,也不会影响畜产品的生产周期。

据测算,新标准在全行业全面推行后,养殖业豆粕年消耗量有望降低约1100万吨,带动减少大豆需求约1400万吨。专家认为,这对于保障我国饲料、养殖业蛋白原料供给和提高利用效率将发挥积极作用,同时有利于提升我国饲料工业水平,促进高质量发展。
