This paper intends to identify changes in producer s attitude resulting from strategies regarding penaltiesgoogle.com/mail/help/intl/pt-br_br/logout.html#hl=pt-br&c=br on milk price, implemented in January 2009, in order improve milk quality, and, also, to evaluate the influence that the daily production scale has on milk quality. The periods between January and December 2008, before implementation of the fines program, and, also, the period from January to December 2009, after implementation of the program were analyzed. Producers from the Unaí, Cabeceira Grande, Uruana de Minas, Buritis, Arinos, Dom Bosco and Natalândia areas were divided into four strata, according to their daily milk production (stratum 1- up to 100 L/day; stratum 2 - from 101 to 500 L/day); stratum 3- from 501 to 1000 L/day; and stratum 4- from 1001 L/day). Somatic cells count (SCC), total bacterial count (TBC), gross protein value (GP) and milk fat (F) were analyzed, through a comparison made between both years and months within each year. During the studied periods, improvement on the TBC levels (P<0.01) in all four producers strata was observed. As for the SCC, improvement was observed only within producers in stratum 1; in stratum 2, there was no change on the SCC levels (P>0.01) between 2008 and 2009; and in strata 3 and 4 there was an increase on SCC values (P<0.01) from 2008 to 2009, which determines that the volume is still considered a priority in country estates with higher production. The GP levels decreased from 2008 to 2009 in all four producers strata, while milk fat decreased (P<0.01) only in stratum 1, presenting no changes in stratum 2 (P>0.01) and increasing (P<0.01) amongst producers in strata 2 and 4. A difference in the four quality variables analyzed among the months of the year in all producers strata was observed, which determines that the change in milk quality vary according to the changes in the daily handling in the farm, either environmental or nutritional. It is thus concluded that the penalties strategy imposed by the company responsible for the milk purchase did not induce milk quality improvement in any of the studied variables; only the TBC levels presented improvement in all producers strata following the implementation of the penalties system. Improvement on SCC, GP and milk fat levels could not be observed in most producers strata, which mark the fact that the production scale is still prioritized by most producers, and, also, that producers with different production scales find distinct difficulties in obtaining better quality milk.
