Quarterly Survey of Milk

Menu do Produto


The survey investigates information on the quantity of raw fluid milk, having as collection unit the establishments that industrialize cow's milk under federal, state or municipal sanitary inspection.

The Monthly Survey of Milk began in 1976 and investigated, using the census strategy, the quantity of milk purchased and/or received for processing; the quantity of milk destined for industrialization in the establishment itself; the quantity of milk transferred and/or marketed; and the amount of milk stored. Over time, changes and improvements have occurred in various aspects of the survey - scope; list of informants; frequency of results; methodology; conceptualizations; collection instruments -, which also reflected in its current denomination. Due to the methodological changes, the data from the Quarterly Survey of Milk, implemented in 1997, should not be compared to those of the Monthly Survey of Milk, since they have different characteristics, both in relation to their lists and to the variables investigated. More recently, in 2013, the on-line questionnaire was introduced, and the informant was given the option of data completion on the Internet.

The survey provides information on the quantities of raw milk procured, raw milk received by transfer, raw milk intended for industrialization, and raw milk sold or transferred to other establishments. The establishments which only carry out the cooling of the milk (cooling stations) for the company to which they belong, or for third parties are not considered in the investigation.

The survey is carried out quarterly, and for each quarter of the calendar year the data are broken down month by month. Its geographic coverage is national, being conditioned to a systematically updated panel, with inclusions and exclusions of establishments due to the dynamics of this productive activity. The results are disclosed, preliminarily, to Brazil and Federation Units, with a gap of one quarter between the data collection and its disclosure. The aggregate results of the reference year are released when the results of the last quarter of the year are put out. It should be noted that the data are not definitive, and may undergo changes until the results of the first quarter of the year after the survey's reference year are disclosed.

Meeting users' demands for a sooner access to livestock information, from the first quarter of 2018 on, the First Results of the Quarterly Survey of Milk for the Brazil level have become available. They are disclosed right after the end of the reference quarter, about a month before the general disclosure.
