The occurrence of isoflavones in dairy feedstuffs and assessment of their transfer into milk
Original language description
The aim of the study was to determine the intake of isoflavones from commonly used dairy diets ant to quantify the transfer of the isoflavones from feed into the bovine milk under on-farm conditions. The study was performed on individual milk samples collected from four dairy farms breeding Holstein (Farm 1 and 2) and Czech Fleckvieh x Holstein cows (Farm 3 and 4). Milk samples were taken from five average yielding cows per herd and were analysed on the content of basic constituents and isoflavones. Samples of feedstuffs were taken at the same time as milk samples and were analysed on the content of dry matter (DM) and isoflavones. In all farms feeding mixtures were identified as the only source of isoflavones in the diets with concentration of total isoflavones ranging between 143.1 and 986.7 mg/kg of DM resulting in total isoflavones intake from 1071 to 8393 mg/d. Daidzein, genistein, glycitein and metabolite equol were detected in milk of all farms. The total carry-over rate of isoflavones from feed into the milk ranged from 0.3 ?g/mg (Farm 4) to 3.6 ?g/mg (Farm1).
