| Summary: | Milk quality is affected by mastitis and practices used during and after milking. The purpose of this study was to evaluate milking practices, hygienic and nutritional quality of milk produced in Granada, Antioquia, by no probabilistic sampling, ten farms belonging to the association ASOGRAN were selected. Assessment of milking practices was realized by direct observation; mastitis detection was made at each farm using the California Test (CMT). At the end of the milking process two samples with an interval of 60 days were taken, each one analyzed for colony forming units (CFU), somatic cell count (SCC), percentages of protein, fat and total solids; during the interval the producers were trained in good milking practices (GMP). Statistical analyzes were performed using the Wilcoxon test. Before training, failure in the GMP was found. Significant differences for the UFC and mastitis tests before and after training were found; furthermore 24% of the mammary glands were affected by subclinical mastitis. In the hygienic milk quality, a mean CFU 6x105 and 3x105, respectively, was detected. The SCC was not significantly different, reporting average values of 630,000 and 750,000, respectively. The nutritional quality showed percentages of fat, protein and total solids, higher than those required by Colombian law. The results indicate the importance of the application of GMP on milk quality. |
