Resumo: | The objective of this study was to evaluate the physicochemical and microbiological parameters of milk in different lactation phases during a year in two Dairy farms producing type A milk (Brazilian Standards) and classified as Farm 1 (G1) and Farm 2 (G2). The 320 raw milk samples were collected to analyze acidity Dornic, California Mastit Test (CMT), Somatic Cells Counting (SCC) and Cryoscopy (0H) during four seasons, in the period of January 00 to January 005. To data statistical analyses a General linear model (GLM) was used. The CMT, the SCC, acidity Dornic and Cryoscopy (0H) results were not significant (P>0.05), during the year seasons, between the farms and in the different lactation phases. The SCC (9 5.000 cells/mL) average results are in disagreement with the legislation. To the Dornic acidity and Cryoscopy (0H), the values had not exceeded the limit demanded by IN5 . The results of mesophilic aerobic organisms counting during autumn (G ) and during spring (G ) had revealed a disagreement with IN5 . High levels of coliforms (TC) and Escherichia coli (EC) were observed in G in all seasons when compared with G . It was demonstrated that the physical-chemistry and microbiological quality are important to handling practical during milks. |

Foram colhidas e analisadas 0 amostras de leite cru para análise da acidez Dornic, California Mastitis Test (CMT), Contagem de Células Somáticas (CCS) e crioscopia. Para as análises estatísticas dos dados, foram empregados os Modelos Lineares Generalizados (GLM). Constatou-se que os resultados das análises estatísticas não foram significativos (P>0,05), durante as estações do ano, nas diferentes fases de lactação, entre as granjas avaliadas. Os resultados médios para CCS (9 5.000 CCS/mL), estão em desacordo com a legislação vigente. Com relação à acidez Dornic e Crioscopia, os valores não excederam o limite exigido pela IN51. Os resultados das contagens médias de aeróbios mesófilos no outono na G2 e na primavera na G mostraram-se em desacordo com a IN5 . No caso dos Coliformes totais e Escherichia coli , observou-se que os resultados médios foram maiores na G , em todas as estações do ano. Evidenciou-se que as qualidades físico-químicas e microbiológicas estão principalmente ligadas às práticas de manejo durante a ordenha.UEL2008-09-27info:eu-repo/semantics/articleinfo:eu-repo/semantics/publishedVersionapplication/pdfhttps://ojs.uel.br/revistas/uel/index.php/semagrarias/article/view/277910.5433/1679-0359.2008v29n3p651Semina: Ciências Agrárias; Vol. 29 No. 3 (2008); 651-660Semina: Ciências Agrárias; v. 29 n. 3 (2008); 651-6601679-03591676-546Xreponame:Semina.
