The raw milk quality from organic and conventional agriculture = Kvalita surového kravského mlieka z ekologického a konvenčného poľnohospodárstva

In the experiment the parameters of milk quality from organic and conventional dairy farm were analyzed. The number of somatic cells was 219.10*3.ml-1 in the organic milk and 242.10*3.ml-1 in the conventional milk. It seems that conditions of organic farming could be able to have a positive effect of health of mammary gland. We found the highest number of somatic cells at the end of the year (336.10*3.ml-1 in organic milk in December, respectively 336.10*3.ml-1 in conventional milk in November). The total bacteria count was higher in organic milk (86.10*3 CFU.ml-1) than conventional (51.10*3 CFU.ml-1) likewise the number of coliform bacteria. Number of coliform bacteria was by conventional milk under 1000 CFU.ml-1 for all samples. The highest number of coliform bacteria in organic milk was achieved in February (1000 CFU.ml-1). We found higher content of fat (4.23 g.100g-1) and protein (3.41 g.100g-1) by organic milk in comparison with the conventional milk (4.11 g.100g-1, resp. 3.39 g.100g-1). The higher content of protein and fat in organic milk and the higher protein content in conventional milk were determined in December. The heat resistance was determined by 96 % ethanol required to coagulation of 2 ml of milk. The conventional milk has significantly lower heat resistance (1.38 ml) than the organic one (1.86 ml). Better heat stability by organic milk and higher content of Ca (144.29 mg.100g-1) correspond with higher technological quality of organic milk. … celý popis
