畜禽饲料的微量元素含量数据库1985

本数据集由国家农业科学数据中心（动物科学和动物医学）建设。
该数据集是在1979至1983年全国有关院校及科研单位的饲料营养成分分析及消化、代谢试验数据的基础上，收集、整理、加工的数据主要是饲料中干物质、主要微量元素（ 铁、铜、锰、锌、硒）的含量数据及资料出处。提供的数据是饲料原样中微量元素含量数据。

This dataset was developed by the National Agricultural Science Data Center (Animal Science and Veterinary Medicine).
Based on data from feed nutrient composition analysis, digestion and metabolism trials conducted by relevant national universities and research institutions between 1979 and 1983, this dataset was compiled, curated and processed. It primarily includes data on the contents of dry matter and major trace elements (iron, copper, manganese, zinc, and selenium) in feeds, along with the source citations of the referenced materials. The provided data corresponds to the trace element contents in raw feed samples.
