Influence of somatic cell count on chemical composition of milk refrigerated of Goiás southwest region

Abstract

The objective was to this study of evaluate the influence of chemical composition on somatic cell count and total bacterial count cool and draw Milk collected in the Southwest Goiás. Data were collected for chemical composition, SCC and TBC of reports issued by the Laboratory of Milk Quality (LQL) of the Center for Food Research (CPA) School of Veterinary and Animal Science, Federal University of Goiás, in Brazil. Data were grouped according to the SCC at six interval ranging ≤ 200,000 SC / mL at ≥ 1.001000 SC/ml ,with the range 1 to 530 samples, 2 to 725 samples, 3 to 469 samples, 4 to 302 samples, 5 to183 samples and 6 with 362 samples. SCC above 1,001,000 SC/mL reflected in the increase of the milk fat content. The higher content of protein and total dry stratum maybe associated with a low SCC, and the lactose contente of Stratum solids non-fat decreases with the increase in SCC. The chemical composition of bulk milk collected in the Southwest Goiás independente of SCC resulted in increased values above the minimum limits established by Brazilian legislation. SCC below 200,000SC/mL is associated with a lower TBC.
