Resumo: The objective of this work was to characterize milk yield and quality of production systems in the southern region of Rio Grande do Sul, and verify the proportion of samples in the range allowed by Federal Normative Instruction 51 (IN 51), created to establish quality parameters for milk in the country. From September 2000 to August 2001, except January, ten dairy production units were monthly evaluated and then classified into three productions systems: specialized, partially specialized and nonspecialized. Bulk tank milk was sampled to determine physicochemical characteristics, somatic cell count and milk production was corrected to 4% milk fat. Production systems differed statistically for milk production, percentages of fat, lactose, casein, total solids, non-fat solids, somatic cell count, acidity and density. Only 41.8% of samples were in the acceptable range of IN 51 rules. Production systems greatest specialization resulted in higher milk yield, reduced somatic cell count and larger percentages for milk casein, lactose and non-fat solids, probably due to better nutritional management and milking hygiene.

De setembro de 2000 a agosto de 2001, exceto janeiro, foram monitoradas, mensalmente, dez unidades de produção leiteira classificadas nos seguintes sistemas de produção: especializado, semi-especializado e não especializado. Em amostras coletadas no tanque resfriador, foram avaliadas características físico-químicas do leite, realizada a contagem de células somáticas e a produção de leite foi corrigida para 4% de gordura. Houve diferença significativa entre os sistemas para produção de leite, porcentagens de gordura, lactose, caseína, sólidos totais, sólidos desengordurados, contagem de células somáticas, acidez titulável e densidade. Consideradas todas as características do leite, apenas 41,8% das amostras se enquadraram nos limites estabelecidos pela IN 51. A maior especialização dos sistemas resultou em aumento da produção de leite e menor contagem de células somáticas, além de maiores valores porcentuais da caseína, lactose e sólidos desengordurados, possivelmente pelo melhor manejo nutricional e higiene na ordenha.Pesquisa Agropecuaria BrasileiraPesquisa Agropecuária BrasileiraZanela, Maira BalbinottiFischer, VivianRibeiro, Maria Edi RochaJunior, Waldyr StumpfZanela, ClaudirMarques, Lúcia TreptowMartins, Paulo Ricardo Garcia2006-01-01info:eu-repo/semantics/articleinfo:eu-repo/semantics/publishedVersionapplication/pdfhttps://seer.sct.embrapa.br/index.php/pab/article/view/7121Pesquisa Agropecuaria Brasileira; v.41, n.1, jan. 2006; 153-159Pesquisa Agropecuária Brasileira; v.41, n.1, jan. 2006; 153-1591678-39210100-104xreponame:Pesquisa Agropecuária Brasileira (Online)instname:Empresa Brasileira de Pesquisa Agropecuária (Embrapa)instacron:EMBRAPAporhttps://seer.sct.embrapa.br/index.php/pab/article/view/7121/4166info:eu-repo/semantics/openAccess2010-12-27T17:54:48Zoai:ojs.seer.sct.embrapa.br:article/7121Revistahttp://seer.sct.embrapa.br/index.php/pabPRIhttps://old.scielo.br/oai/scielo-oai.phppab@sct.embrapa.br || sct.pab@embrapa.br1678-39210100-204Xopendoar:2010-12-27T17:54:48Pesquisa Agropecuária Brasileira (Online) - Empresa Brasileira de Pesquisa Agropecuária (Embrapa)false
