Statistical processing

Source data

It is a census where all companies producing compound feed stuff in Denmark delivers data to the statistics. At the moment 13 companies delivers data to the statistics.

Frequency of data collection

Through 2022, data has been collected semi-annually. From 2023, data will be collected annually.

Data collection

Data are gathered electronically in a questionnaires, which the companies upload to Statistics Denmark. The statistics have an information page in Danish. The companies fill in and upload a spreadsheet, which consists of two sheets. In the first sheet, they indicate the quantities of the company's production of various feed mixtures, excluding exports, as well as their quantities of purchased supplementary mixtures, in own production, excl. export. In the second sheet, they indicate the quantities of a wide range of raw materials in their own production of compound feed, excluding export.

Data validation

Data from the individual reporting sheets are collected and partial quantities and total quantities are calculated and compared with previous periods. Data are first debugged and validated on a micro level, for example by comparing individual reports with reports from previous periods. If these comparisons give rise to questions, the company is contacted for an in-depth explanation and a possible re-report. Data are then checked at the macro level. This is done by comparing partial quantities, e.g. Ready-to-use feed mixtures for sows, and by comparing the total quantities, e.g. Cattle feed mixtures in total, with previous total quantities and the development in the cattle and pig populations.

Data compilation

The validated data are added together, and thereby the total production of feed mixtures is obtained. Data are not weighted, nor are they imputed.

Adjustment

Data are not corrected.
