摘要
牧草是草食动物最主要的营养来源。牧草品质的优劣不仅影响家畜的生长发育和生产效率,也决定着最终畜产品的产量与品质。牧草品质的优劣主要取决于牧草营养成分及其消化率、适口性、以及牧草中所含抗营养因子和真菌毒素、霉菌毒素的含量水平。近红外光谱技术(NIRS)是一种低成本、快速、简单、无损的定性、定量分析技术,已在许多领域广泛应用。该文简要介绍了NIRS的原理和特点,详细综述了NIRS在牧草品质分析、牧草育种、牧草品种鉴定和性状分类中的应用。通过较全面综述NIRS在牧草领域中的应用现状,以期有助于NIRS在我国牧草领域中的发展。
The majority of nutrients in ruminants and other herbivores come from forages. Forage quality not only affects the growth and production efficiency of livestock, but also determines the final output and quality of livestock products. Forage qual- ity mainly depends on nutrient coneentrations and their digestibility, palatability and the level of presence of antiquality factors and mycotoxins in forage. Near infrared reflectance speetroscopy（NIRS） has been widely used in many research areas because it is a inexpensive, rapid, simple and nondestructive technique offering the potential for qualitative and quantitative analysis. The present paper briefly introduces the principle and characteristics of NIRS, detailedly expounds the application of NIRS in forage quality. In addition, other applications of near infrared spectroscopy technique in forage are also discussed, including forage breeding, identification of variety and classification by kind. This paper comprehensively reviews the status quo of application of NIRS in forage filed, in order to contribute to promoting development of NIRS in this field in China.
