| Summary: | Mastitis is the inflammation of the mammary glands in response to neutralize infectious agents and return to normal function. This inflammatory response decreases the synthesis of different components, which reduce the milk quality. The purpose of this study was to determine physicochemical and microbiological quality of tank milk and the udder health in 15 dual-purpose system enterprises in Monteria (Cordoba), chosen by non-probability sampling and a cross-sectional study. A tank milk sample in each of the enterprises involved in the study was collected. The density, acidity percentage, protein, lactose, mesophilic and somatic cell count was determined. Also, the prevalence of mastitis and, by extrapolation, economic losses were calculated. Statistical analysis was executed using SAS software. Physicochemical values were within normal values. Mesophilic count was 160.347 ± 213.354 Cfu/mL and somatic cell count of 345.133 ± 302.241 SC/mL. In all enterprises the prevalence of mastitis varied from 13.8% to 74.7%. Linear regression was found between the prevalence of mastitis and somatic cell count (R2=0,867). In seven of these enterprises, somatic cell count was up to 250.000 SC/mL, which warrants the immediate implementation of prevention and control of bovine mastitis. |
