Effect of the level of technology of dairy farms in the province of Lima on the compositional, hygienic and sanitary quality of milk

The aim of this study was to establish the relationship between the level of technology and the quality of milk in dairy farms in the province of Lima, Peru. The study was carried out in 18 farms. Data was collected through surveys, as well as analysis of milk samples collected during three consecutive days. Variables related to the level of technology of the farms, as well as the physical, compositional, hygienic and sanitary quality of the milk were evaluated. The results revealed average technical scores of 7.1/10 in management, 4.3/10 in facilities and resources, 4.2/6 in milking, and 15.6/26 in the global technification. Regarding the quality of the milk, average temperatures of 18.38 °C, pH of 6.60, average density of 1.030 g/mL, total solids of 12.11%, and fat of 3.46% were recorded. The mean count of mesophilic bacteria was 210x106, coliforms 6x107, and somatic cells 300x105 cells/mL. Significant negative correlations were found between the level of technology with the storage temperature, the sedimentation score, and the count of mesophilic and coliform bacteria in the milk. In addition, it was evident that farms with better level of technology presented significantly better milk quality parameters compared to those with less technology.

El objetivo del estudio fue establecer la relación entre el nivel de tecnificación y la calidad de la leche en establos lecheros de la provincia de Lima, Perú. El estudio se llevó a cabo en 18 establos. Se recolectaron datos a través de encuestas, así como análisis de muestras de leche colectada durante tres días consecutivos. Se evaluaron variables relacionadas con el nivel de tecnificación de los establos, así como la calidad física, composicional, higiénica y sanitaria de la leche. Los resultados revelaron puntuaciones promedio de tecnificación de 7.1/10 en manejo, 4.3/10 en instalaciones y recursos, 4.2/6 en el ordeño, y 15.6/26 en tecnificación global. En cuanto a la calidad de la leche, se registraron temperaturas promedio de 18.38 °C, pH de 6.60, densidad media de 1.030 g/mL, sólidos totales de 12.11%, y grasa de 3.46%. El conteo promedio de bacterias mesófilas fue de 210x106, coliformes de 6x107, y células somáticas de 300x105 cél/mL. Se encontraron correlaciones negativas significativas entre el nivel de tecnificación con la temperatura de almacenamiento, el puntaje de sedimentación, y el conteo de bacterias mesófilas y coliformes en la leche. Además, quedó evidente que los establos con mayor nivel de tecnificación presentaron parámetros de calidad de la leche significativamente mejores en comparación con aquellos con menor tecnificación.
