摘要
由于畜禽水产养殖业的快速发展,优质饲料蛋白面临需求量快速增加、原料价格上涨和品质参差不齐等问题,寻找优质的替代蛋白成为解决问题的关键。棉籽蛋白作为一种优质蛋白在动物饲料中广泛使用,蛋白质含量可以达到40%以上,资源丰富且价格低廉,但其存在的抗营养因子限制了其在生产中的应用。随着棉籽蛋白生产工艺的不断发展,通过合理有效的科学技术手段去除棉籽蛋白的抗营养因子并进一步优化其营养组成,其营养价值和适口性不断提高。合理利用棉籽蛋白能在保证动物生长性能的同时可以大幅降低动物饲料成本,但关于棉籽蛋白在不同养殖动物和生长阶段的适宜添加量和添加形式,对动物吸收、代谢、生理功能的影响及作用机制研究尚未明确。作者阐述了棉籽蛋白的营养价值、生产工艺、替代饲料蛋白源的研究现状以及影响棉籽蛋白利用价值的因素,为棉籽蛋白的合理使用和进一步提高棉籽蛋白利用价值提供参考。
Due to the rapid development of livestock,poultry,and aquaculture industries,high-quality feed protein is facing challenges such as increasing demand,rising raw material prices,and inconsistent quality.Finding high-quality alternative proteins has become the key to solving these problems.Cottonseed protein,as a high-quality protein,is widely used in animal feed.It has a protein content of over 40%,is abundant in resources,and has a low price.However,the presence of anti-nutritional factors in cottonseed protein limits its application in production.With the continuous development of cottonseed protein production technology,the removal of anti-nutritional factors from cottonseed protein and further optimization of its nutritional composition through reasonable and effective scientific and technological methods have continuously improved its nutritional value and palatability.Rational utilization of cottonseed protein can not only ensure animal growth performance but also significantly reduce animal feed costs.However,the appropriate addition amount and form of cottonseed protein in different aquaculture animals and growth stages,as well as its impact on animal absorption,metabolism,physiological functions,and mechanisms,have not been clearly studied.The author elucidates the nutritional value,production technology,research status of alternative feed protein sources,and factors influencing the utilization value of cottonseed protein.This provides a reference for the rational use of cottonseed protein and further improvement of its utilization value.
