Avaliação da qualidade das características físico-químicas do leite produzido em Roque Gonzales - RS

Abstract

The search for quality in goods and services is inherent to the consumer market. Especially the refrigerated raw type of milk delivered to the industry for processing, in which the search for quality is constant. Laboratorial tests, carried out monthly with milk samples of the producers, are important to evaluate the quality of milk delivered to the industry, because the larger the percentage of total solids (TS) that compose the milk is, the larger is the dairy products profitability; and the more appropriate the SCC (somatic cell count) of the milk is, the larger is the productivity and the better is the herd sanitary conditions. In the present work, descriptive analyses were carried out to evaluate the quality of milk delivered to the unity Avipal S/A from Roque Gonzales by 56 producers from five routes. The Box-Plot of all variables was designed using the software Statistica 7.0. It was concluded that none producer presented contents that corresponds to the Normative Instruction n. 51/2002 of the Ministry of Agriculture, Livestock and Food Supply, in all variables during the period. The season influences in the milk quality; the routes present differences in the quality of collected milk, but none is emphasized in all variables. The variables that presented the most significant problems were the SCCs, protein and, as a consequence the TSs, in this way, both payment forms in question are damaged. These results will be delivered to the industry and to the producers who presented low quality milk, because the milk out of these patterns is injurious to the industry, which loses in dairy quality produced and to the producer, which receives less for the milk, not mentioning the loss of productivity occasioned by the high index of SCC in the milk.
